Rule 23. Class Actions(a) Prerequisites. One or more members of a class may sue or be sued as representative parties on behalf of all members only if:(1) the class is so numerous that joinder of all members is impracticable;(2) there are questions of law or fact common to the class;(3) the claims or defenses of the representative parties are typical of the claims or defenses of the class; and(4) the representative parties will fairly and adequately protect the interests of the class.(b) Types of Class Actions. A class action may be maintained if Rule 23(a) is satisfied and if:(1) prosecuting separate actions by or against individual class members would create a risk of:(A) inconsistent or varying adjudications with respect to individual class members that would establish incompatible standards of conduct for the party opposing the class; or(B) adjudications with respect to individual class members that, as a practical matter, would be dispositive of the interests of the other members not parties to the individual adjudications or would substantially impair or impede their ability to protect their interests;(2) the party opposing the class has acted or refused to act on grounds that apply generally to the class, so that final injunctive relief or corresponding declaratory relief is appropriate respecting the class as a whole; or(3) the court finds that the questions of law or fact common to class members predominate over any questions affecting only individual members, and that a class action is superior to other available methods for fairly and efficiently adjudicating the controversy. The matters pertinent to these findings include:(A) the class members’ interests in individually controlling the prosecution or defense of separate actions;(B) the extent and nature of any litigation concerning the controversy already begun by or against class members;(C) the desirability or undesirability of concentrating the litigation of the claims in the particular forum; and(D) the likely difficulties in managing a class action.(c) Certification Order; Notice to Class Members; Judgment; Issues Classes; Subclasses. (1) Certification Order.(A) Time to Issue. At an early practicable time after a person sues or is sued as a class representative, the court must determine by order whether to certify the action as a class action.(B) Defining the Class; Appointing Class Counsel. An order that certifies a class action must define the class and the class claims, issues, or defenses, and must appoint class counsel under Rule 23(g).(C) Altering or Amending the Order. An order that grants or denies class certification may be altered or amended before final judgment.(2) Notice.(A) For (b)(1) or (b)(2) Classes. For any class certified under Rule 23(b)(1) or (b)(2), the court may direct appropriate notice to the class.(B) For (b)(3) Classes. For any class certified under Rule 23(b)(3), the court must direct to class members the best notice that is practicable under the circumstances, including individual notice to all members who can be identified through reasonable effort. The notice must clearly and concisely state in plain, easily understood language:(i) the nature of the action;(ii) the definition of the class certified;(iii) the class claims, issues, or defenses;(iv) that a class member may enter an appearance through an attorney if the member so desires;(v) that the court will exclude from the class any member who requests exclusion;(vi) the time and manner for requesting exclusion; and(vii) the binding effect of a class judgment on members under Rule 23(c)(3).(3) Judgment. Whether or not favorable to the class, the judgment in a class action must:(A) for any class certified under Rule 23(b)(1) or (b)(2), include and describe those whom the court finds to be class members; and(B) for any class certified under Rule 23(b)(3), include and specify or describe those to whom the Rule 23(c)(2) notice was directed, who have not requested exclusion, and whom the court finds to be class members.(4) Particular Issues. When appropriate, an action may be brought or maintained as a class action with respect to particular issues.(5) Subclasses. When appropriate, a class may be divided into subclasses that are each treated as a class under this rule.(d) Conducting the Action. (1) In General. In conducting an action under this rule, the court may issue orders that:(A) determine the course of proceedings or prescribe measures to prevent undue repetition or complication in presenting evidence or argument;(B) require—to protect class members and fairly conduct the action—giving appropriate notice to some or all class members of:(i) any step in the action;(ii) the proposed extent of the judgment; or(iii) the members’ opportunity to signify whether they consider the representation fair and adequate, to intervene and present claims or defenses, or to otherwise come into the action;(C) impose conditions on the representative parties or on intervenors;(D) require that the pleadings be amended to eliminate allegations about representation of absent persons and that the action proceed accordingly; or(E) deal with similar procedural matters.(2) Combining and Amending Orders. An order under Rule 23(d)(1) may be altered or amended from time to time and may be combined with an order under Rule 16.(e) Settlement, Voluntary Dismissal, or Compromise. The claims, issues, or defenses of a certified class may be settled, voluntarily dismissed, or compromised only with the court’s approval. The following procedures apply to a proposed settlement, voluntary dismissal, or compromise:(1) The court must direct notice in a reasonable manner to all class members who would be bound by the proposal.(2) If the proposal would bind class members, the court may approve it only after a hearing and on finding that it is fair, reasonable, and adequate.(3) The parties seeking approval must file a statement identifying any agreement made in connection with the proposal.(4) If the class action was previously certified under Rule 23(b)(3), the court may refuse to approve a settlement unless it affords a new opportunity to request exclusion to individual class members who had an earlier opportunity to request exclusion but did not do so.(5) Any class member may object to the proposal if it requires court approval under this subdivision (e); the objection may be withdrawn only with the court’s approval.(f) Appeals. A court of appeals may permit an appeal from an order granting or denying class-action certification under this rule if a petition for permission to appeal is filed with the circuit clerk within 14 days after the order is entered. An appeal does not stay proceedings in the district court unless the district judge or the court of appeals so orders.(g) Class Counsel. (1) Appointing Class Counsel. Unless a statute provides otherwise, a court that certifies a class must appoint class counsel. In appointing class counsel, the court:(A) must consider:(i) the work counsel has done in identifying or investigating potential claims in the action;(ii) counsel’s experience in handling class actions, other complex litigation, and the types of claims asserted in the action;(iii) counsel’s knowledge of the applicable law; and(iv) the resources that counsel will commit to representing the class;(B) may consider any other matter pertinent to counsel’s ability to fairly and adequately represent the interests of the class;(C) may order potential class counsel to provide information on any subject pertinent to the appointment and to propose terms for attorney’s fees and nontaxable costs;(D) may include in the appointing order provisions about the award of attorney’s fees or nontaxable costs under Rule 23(h); and(E) may make further orders in connection with the appointment.(2) Standard for Appointing Class Counsel. When one applicant seeks appointment as class counsel, the court may appoint that applicant only if the applicant is adequate under Rule 23(g)(1) and (4). If more than one adequate applicant seeks appointment, the court must appoint the applicant best able to represent the interests of the class.(3) Interim Counsel. The court may designate interim counsel to act on behalf of a putative class before determining whether to certify the action as a class action.(4) Duty of Class Counsel. Class counsel must fairly and adequately represent the interests of the class.(h) Attorney’s Fees and Nontaxable Costs. In a certified class action, the court may award reasonable attorney’s fees and nontaxable costs that are authorized by law or by the parties’ agreement. The following procedures apply:(1) A claim for an award must be made by motion under Rule 54(d)(2), subject to the provisions of this subdivision (h), at a time the court sets. Notice of the motion must be served on all parties and, for motions by class counsel, directed to class members in a reasonable manner.(2) A class member, or a party from whom payment is sought, may object to the motion.(3) The court may hold a hearing and must find the facts and state its legal conclusions under Rule 52(a).(4) The court may refer issues related to the amount of the award to a special master or a magistrate judge, as provided in Rule 54(d)(2)(D). (As amended Feb. 28, 1966, eff. July 1, 1966; Mar. 2, 1987, eff. Aug. 1, 1987; Apr. 24, 1998, eff. Dec. 1, 1998; Mar. 27, 2003, eff. Dec. 1, 2003; Apr. 30, 2007, eff. Dec. 1, 2007; Mar. 26, 2009, eff. Dec. 1, 2009.) Note to Subdivision (a). This is a substantial restatement of [former] Equity Rule 38 (Representatives of Class) as that rule has been construed. It applies to all actions, whether formerly denominated legal or equitable. For a general analysis of class actions, effect of judgment, and requisites of jurisdiction see Moore, Federal Rules of Civil Procedure: Some Problems Raised by the Preliminary Draft, 25 Georgetown L.J. 551, 570 et seq. (1937); Moore and Cohn, Federal Class Actions, 32 Ill.L.Rev. 307 (1937); Moore and Cohn, Federal Class Actions—Jurisdiction and Effect of Judgment, 32 Ill.L.Rev. 555—567 (1938); Lesar, Class Suits and the Federal Rules, 22 Minn.L.Rev. 34 (1937); cf. Arnold and James, Cases on Trials, Judgments and Appeals (1936) 175; and see Blume, Jurisdictional Amount in Representative Suits, 15 Minn.L.Rev. 501 (1931). The general test of [former] Equity Rule 38 (Representatives of Class) that the question should be “one of common or general interest to many persons constituting a class so numerous as to make it impracticable to bring them all before the court,” is a common test. For states which require the two elements of a common or general interest and numerous persons, as provided for in [former] Equity Rule 38, see Del.Ch.Rule 113; Fla.Comp.Gen.Laws Ann. (Supp., 1936) § 4918 (7); Georgia Code (1933) § 37-1002, and see English Rules Under the Judicature Act (The Annual Practice, 1937) O. 16, r. 9. For statutory provisions providing for class actions when the question is one of common or general interest or when the parties are numerous, see Ala.Code Ann. (Michie, 1928) § 5701; 2 Ind.Stat.Ann. (Burns, 1933) § 2-220; N.Y.C.P.A. (1937) § 195; Wis.Stat. (1935) § 260.12. These statutes have, however, been uniformly construed as though phrased in the conjunctive. See Garfein v. Stiglitz, 260 Ky. 430, 86 S.W.(2d) 155 (1935). The rule adopts the test of [former] Equity Rule 38, but defines what constitutes a “common or general interest”. Compare with code provisions which make the action dependent upon the propriety of joinder of the parties. See Blume, The “Common Questions” Principle in the Code Provision for Representative Suits, 30 Mich.L.Rev. 878 (1932). For discussion of what constitutes “numerous persons” see Wheaton, Representative Suits Involving Numerous Litigants, 19 Corn.L.Q. 399 (1934); Note, 36 Harv.L.Rev. 89 (1922). Clause (1), Joint, Common, or Secondary Right. This clause is illustrated in actions brought by or against representatives of an unincorporated association. See Oster v. Brotherhood of Locomotive Firemen and Enginemen, 271 Pa. 419, 114 Atl. 377 (1921); Pickett v. Walsh, 192 Mass. 572, 78 N.E. 753, 6 L.R.A. (N.S.) 1067 (1906); Colt v. Hicks, 97 Ind.App. 177, 179 N.E. 335 (1932). Compare Rule 17(b) as to when an unincorporated association has capacity to sue or be sued in its common name; United Mine Workers of America v. Coronado Coal Co., 259 U.S. 344 (1922) (an unincorporated association was sued as an entity for the purpose of enforcing against it a federal substantive right); Moore, Federal Rules of Civil Procedure: Some Problems Raised by the Preliminary Draft, 25 Georgetown L.J. 551, 566 (for discussion of jurisdictional requisites when an unincorporated association sues or is sued in its common name and jurisdiction is founded upon diversity of citizenship). For an action brought by representatives of one group against representatives of another group for distribution of a fund held by an unincorporated association, see Smith v. Swormstedt, 16 How. 288 (U.S. 1853). Compare Christopher, et al. v. Brusselback, 58 S.Ct. 350 [302 U.S. 500] (1938). For an action to enforce rights held in common by policyholders against the corporate issuer of the policies, see Supreme Tribe of Ben Hur v. Cauble, 255 U.S. 356 (1921). See also Terry v. Little, 101 U.S. 216 (1880); John A. Roebling’s Sons Co. v. Kinnicutt, 248 Fed. 596 (D.C.N.Y., 1917) dealing with the right held in common by creditors to enforce the statutory liability of stockholders. Typical of a secondary action is a suit by stockholders to enforce a corporate right. For discussion of the general nature of these actions see Ashwander v. Tennessee Valley Authority, 297 U.S. 288 (1936); Glenn, The Stockholder’s Suit—Corporate and Individual Grievances, 33 Yale L.J. 580 (1924); McLaughlin, Capacity of Plaintiff-Stockholder to Terminate a Stockholder’s Suit, 46 Yale L.J. 421 (1937). See also Subdivision (b) of this rule which deals with Shareholder’s Action; Note, 15 Minn.L.Rev. 453 (1931). Clause (2). A creditor’s action for liquidation or reorganization of a corporation is illustrative of this clause. An action by a stockholder against certain named defendants as representatives of numerous claimants presents a situation converse to the creditor’s action. Clause (3). See Everglades Drainage League v. Napoleon Broward Drainage Dist., 253 Fed. 246 (D.C.Fla., 1918); Gramling v. Maxwell, 52 F.(2d) 256 (D.C.N.C., 1931), approved in 30 Mich.L.Rev. 624 (1932); Skinner v. Mitchell, 108 Kan. 861, 197 Pac. 569 (1921); Duke of Bedford v. Ellis (1901) A.C. 1, for class actions when there were numerous persons and there was only a question of law or fact common to them; and see Blume, The “Common Questions” Principle in the Code Provision for Representative Suits, 30 Mich.L.Rev. 878 (1932). Note to Subdivision (b). This is [former] Equity Rule 27 (Stockholder’s Bill) with verbal changes. See also Hawes v. Oakland, 104 U.S. 450, 26 L.Ed. 827 (1882) and former Equity Rule 94, promulgated January 23, 1882, 104 U.S. IX. Note to Subdivision (c). See McLaughlin, Capacity of Plaintiff-Stockholder to Terminate a Stockholder’s Suit, 46 Yale L.J. 421 (1937). Subdivision (b), relating to secondary actions by shareholders, provides among other things, that in, such an action the complainant “shall aver (1) that the plaintiff was a shareholder at the time of the transaction of which he complains or that his share thereafter devolved on him by operation of law...” As a result of the decision in Erie R. Co. v. Tompkins, 304 U.S. 64 (decided April 25, 1938, after this rule was promulgated by the Supreme Court, though before it took effect) a question has arisen as to whether the provision above quoted deals with a matter of substantive right or is a matter of procedure. If it is a matter of substantive law or right, then under Erie R. Co. v. Tompkins clause (1) may not be validly applied in cases pending in states whose local law permits a shareholder to maintain such actions, although not a shareholder at the time of the transactions complained of. The Advisory Committee, believing the question should be settled in the courts, proposes no change in Rule 23 but thinks rather that the situation should be explained in an appropriate note. The rule has a long history. In Hawes v. Oakland (1882) 104 U.S. 450, the Court held that a shareholder could not maintain such an action unless he owned shares at the time of the transactions complained of, or unless they devolved on him by operation of law. At that time the decision in Swift v. Tyson (1842) 16 Peters 1, was the law, and the federal courts considered themselves free to establish their own principles of equity jurisprudence, so the Court was not in 1882 and has not been, until Erie R. Co. v. Tompkins in 1938, concerned with the question whether Hawes v. Oakland dealt with substantive right or procedure. Following the decision in Hawes v. Oakland, and at the same term, the Court, to implement its decision, adopted [former] Equity Rule 94, which contained the same provision above quoted from Rule 23 F.R.C.P. The provision in [former] Equity Rule 94 was later embodied in [former] Equity Rule 27, of which the present Rule 23 is substantially a copy. In City of Quincy v. Steel (1887) 120 U.S. 241, 245, the Court referring to Hawes v. Oakland said: “In order to give effect to the principles there laid down, this Court at that term adopted Rule 94 of the rules of practice for courts of equity of the United States.” Some other cases dealing with [former] Equity Rules 94 or 27 prior to the decision in Erie R. Co. v. Tompkins are Dimpfel v. Ohio & Miss. R. R. (1884) 110 U.S. 209; Illinois Central R. Co. v. Adams (1901) 180 U.S. 28, 34; Venner v. Great Northern Ry. (1908) 209 U.S. 24, 30; Jacobson v. General Motors Corp. (S.D.N.Y. 1938) 22 F.Supp. 255, 257. These cases generally treat Hawes v. Oakland as establishing a “principle” of equity, or as dealing not with jurisdiction but with the “right” to maintain an action, or have said that the defense under the equity rule is analogous to the defense that the plaintiff has no “title” and results in a dismissal “for want of equity.” Those state decisions which held that a shareholder acquiring stock after the event may maintain a derivative action are founded on the view that it is a right belonging to the shareholder at the time of the transaction and which passes as a right to the subsequent purchaser. See Pollitz v. Gould (1911) 202 N.Y. 11. The first case arising after the decision in Erie R. Co. v. Tompkins, in which this problem was involved, was Summers v. Hearst (S.D.N.Y. 1938) 23 F.Supp. 986. It concerned [former] Equity Rule 27, as Federal Rule 23 was not then in effect. In a well considered opinion Judge Leibell reviewed the decisions and said: “The federal cases that discuss this section of Rule 27 support the view that it states a principle of substantive law.” He quoted Pollitz v. Gould (1911) 202 N.Y. 11, as saying that the United States Supreme Court “seems to have been more concerned with establishing this rule as one of practice than of substantive law” but that “whether it be regarded as establishing a principle of law or a rule of practice, this authority has been subsequently followed in the United States courts.” He then concluded that, although the federal decisions treat the equity rule as “stating a principle of substantive law”, if [former] “Equity Rule 27 is to be modified or revoked in view of Erie R. Co. v. Tompkins, it is not the province of this Court to suggest it, much less impliedly to follow that course by disregarding the mandatory provisions of the Rule.” Some other federal decisions since 1938 touch the question. In Piccard v. Sperry Corporation (S.D.N.Y. 1941) 36 F.Supp. 1006, 1009-10, affirmed without opinion (C.C.A.2d, 1941) 120 F.(2d) 328, a shareholder, not such at the time of the transactions complained of, sought to intervene. The court held an intervenor was as much subject to Rule 23 as an original plaintiff; and that the requirement of Rule 23(b) was “a matter of practice,” not substance, and applied in New York where the state law was otherwise, despite Erie R. Co. v. Tompkins. In York v. Guaranty Trust Co. of New York (C.C.A.2d, 1944) 143 F.(2d) 503, rev’d on other grounds (1945) 65 S.Ct. 1464, the court said: “Restrictions on the bringing of stockholders’ actions, such as those imposed by F.R.C.P. 23(b) or other state statutes are procedural,” citing the Piccard and other cases. In Gallup v. Caldwell (C.C.A.3d, 1941) 120 F.(2d) 90, 95, arising in New Jersey, the point was raised but not decided, the court saying that it was not satisfied that the then New Jersey rule differed from Rule 23(b), and that “under the circumstances the proper course was to follow Rule 23(b).” In Mullins v. De Soto Securities Co. (W.D.La. 1942) 45 F.Supp. 871, 878, the point was not decided, because the court found the Louisiana rule to be the same as that stated in Rule 23(b). In Toebelman v. Missouri-Kansas Pipe Line Co. (D.Del. 1941) 41 F.Supp. 334, 340, the court dealt only with another part of Rule 23(b), relating to prior demands on the stockholders and did not discuss Erie R. Co. v. Tompkins, or its effect on the rule. “It seems to me the rule does not go beyond procedure. * * * Simply because a particular plaintiff cannot qualify as a proper party to maintain such an action does not destroy or even whittle at the cause of action. The cause of action exists until a qualified plaintiff can get it started in a federal court.” In Bankers Nat. Corp. v. Barr (S.D.N.Y. 1945) 9 Fed.Rules Serv. 23b.11, Case 1, the court held Rule 23(b) to be one of procedure, but that whether the plaintiff was a stockholder was a substantive question to be settled by state law. The New York rule, as stated in Pollitz v. Gould, supra, has been altered by an act of the New York Legislature (Chapter 667, Laws of 1944, effective April 9, 1944, General Corporation Law, § 61) which provides that “in any action brought by a shareholder in the right of a... corporation, it must appear that the plaintiff was a stockholder at the time of the transaction of which he complains, or that his stock thereafter devolved upon him by operation of law.” At the same time a further and separate provision was enacted, requiring under certain circumstances the giving of security for reasonable expenses and attorney’s fees, to which security the corporation in whose right the action is brought and the defendants therein may have recourse. (Chapter 668, Laws of 1944, effective April 9, 1944, General Corporation Law, § 61-b.) These provisions are aimed at so-called “strike” stockholders’ suits and their attendant abuses. Shielcrawt v. Moffett (Ct.App. 1945) 294 N.Y. 180, 61 N.E.(2d) 435, rev’g 51 N.Y.S.(2d) 188, aff’g 49 N.Y.S.(2d) 64; Noel Associates, Inc. v. Merrill (Sup.Ct. 1944) 184 Misc. 646, 53 N.Y.S.(2d) 143. Insofar as § 61 is concerned, it has been held that the section is procedural in nature. Klum v. Clinton Trust Co. (Sup.Ct. 1944) 183 Misc. 340, 48 N.Y.S.(2d) 267; Noel Associates, Inc. v. Merrill, supra. In the latter case the court pointed out that “The 1944 amendment to Section 61 rejected the rule laid down in the Pollitz case and substituted, in place thereof, in its precise language, the rule which has long prevailed in the Federal Courts and which is now Rule 23(b)...” There is, nevertheless, a difference of opinion regarding the application of the statute to pending actions. See Klum v. Clinton Trust Co., supra (applicable); Noel Associates, Inc. v. Merrill, supra (inapplicable). With respect to § 61-b, which may be regarded as a separate problem (Noel Associates, Inc. v. Merrill, supra), it has been held that even though the statute is procedural in nature—a matter not definitely decided—the Legislature evinced no intent that the provision should apply to actions pending when it became effective. Shielcrawt v. Moffett, supra. As to actions instituted after the effective date of the legislation, the constitutionality of § 61-b is in dispute. See Wolf v. Atkinson (Sup.Ct. 1944) 182 Misc. 675, 49 N.Y.S.(2d) 703 (constitutional); Citron v. Mangel Stores Corp. (Sup.Ct. 1944) — Misc. —, 50 N.Y.S.(2d) 416 (unconstitutional); Zlinkoff, The American Investor and the Constitutionality of Section 61-B of the New York General Corporation Law (1945) 54 Yale L.J. 352. New Jersey also enacted a statute, similar to Chapters 667 and 668 of the New York law. See P.L. 1945, Ch. 131, R.S.Cum.Supp. 14:3-15. The New Jersey provision similar to Chapter 668 (§ 61-b) differs, however, in that it specifically applies retroactively. It has been held that this provision is procedural and hence will not govern a pending action brought against a New Jersey corporation in the New York courts. Shielcrawt v. Moffett (Sup.Ct.N.Y. 1945) 184 Misc. 1074, 56 N.Y.S.(2d) 134. See also generally, 2 Moore’s Federal Practice (1938) 2250-2253, and Cum.Supplement § 23.05. The decisions here discussed show that the question is a debatable one, and that there is respectable authority for either view, with a recent trend towards the view that Rule 23(b)(1) is procedural. There is reason to say that the question is one which should not be decided by the Supreme Court ex parte, but left to await a judicial decision in a litigated case, and that in the light of the material in this note, the only inference to be drawn from a failure to amend Rule 23(b) would be that the question is postponed to await a litigated case. The Advisory Committee is unanimously of the opinion that this course should be followed. If, however, the final conclusion is that the rule deals with a matter of substantive right, then the rule should be amended by adding a provision that Rule 23(b)(1) does not apply in jurisdictions where state law permits a shareholder to maintain a secondary action, although he was not a shareholder at the time of the transactions of which he complains. Difficulties with the original rule. The categories of class actions in the original rule were defined in terms of the abstract nature of the rights involved: the so-called “true” category was defined as involving “joint, common, or secondary rights”; the “hybrid” category, as involving “several” rights related to “specific property”; the “spurious” category, as involving “several” rights affected by a common question and related to common relief. It was thought that the definitions accurately described the situations amendable to the class-suit device, and also would indicate the proper extent of the judgment in each category, which would in turn help to determine the res judicata effect of the judgment if questioned in a later action. Thus the judgments in “true” and “hybrid” class actions would extend to the class (although in somewhat different ways); the judgment in a “spurious” class action would extend only to the parties including intervenors. See Moore, Federal Rules of Civil Procedure: Some Problems Raised by the Preliminary Draft, 25 Geo.L.J. 551, 570-76 (1937). In practice, the terms “joint,” “common,” etc., which were used as the basis of the Rule 23 classification proved obscure and uncertain. See Chaffee, Some Problems of Equity 245-46, 256-57 (1950); Kalven & Rosenfield, The Contemporary Function of the Class Suit, 8 U. of Chi.L.Rev. 684, 707 & n. 73 (1941); Keeffe, Levy & Donovan, Lee Defeats Ben Hur, 33 Corn.L.Q. 327, 329-36 (1948); Developments in the Law: Multiparty Litigation in the Federal Courts, 71 Harv.L.Rev. 874, 931 (1958); Advisory Committee’s Note to Rule 19, as amended. The courts had considerable difficulty with these terms. See, e.g., Gullo v. Veterans’ Coop. H. Assn., 13 F.R.D. 11 (D.D.C. 1952); Shipley v. Pittsburgh & L. E. R. Co., 70 F.Supp. 870 (W.D.Pa. 1947); Deckert v. Independence Shares Corp., 27 F.Supp. 763 (E.D.Pa. 1939), rev’d, 108 F.2d 51 (3d Cir. 1939), rev’d, 311 U.S. 282 (1940), on remand, 39 F.Supp. 592 (E.D.Pa. 1941), rev’d sub nom. Pennsylvania Co. for Ins. on Lives v. Deckert, 123 F.2d 979 (3d Cir. 1941) (see Chafee, supra, at 264-65). Nor did the rule provide an adequate guide to the proper extent of the judgments in class actions. First, we find instances of the courts classifying actions as “true” or intimating that the judgments would be decisive for the class where these results seemed appropriate but were reached by dint of depriving the word “several” of coherent meaning. See, e.g., System Federation No. 91 v. Reed, 180 F.2d 991 (6th Cir. 1950); Wilson v. City of Paducah, 100 F.Supp. 116 (W.D.Ky. 1951); Citizens Banking Co. v. Monticello State Bank, 143 F.2d 261 (8th Cir. 1944); Redmond v. Commerce Trust Co., 144 F.2d 140 (8th Cir. 1944), cert. denied, 323 U.S. 776 (1944); United States v. American Optical Co., 97 F.Supp. 66 (N.D.Ill. 1951); National Hairdressers’ & C. Assn. v. Philad. Co., 34 F.Supp. 264 (D.Del. 1940); 41 F.Supp. 701 (D.Del. 1940), aff’d mem., 129 F.2d 1020 (3d Cir. 1942). Second, we find cases classified by the courts as “spurious” in which, on a realistic view, it would seem fitting for the judgments to extend to the class. See, e.g., Knapp v. Bankers Sec. Corp., 17 F.R.D. 245 (E.D.Pa. 1954); aff’d 230 F.2d 717 (3d Cir. 1956); Giesecke v. Denver Tramway Corp., 81 F.Supp. 957 (D.Del. 1949); York v. Guaranty Trust Co., 143 F.2d 503 (2d Cir. 1944), rev’d on grounds not here relevant, 326 U.S. 90 (1945) (see Chafee, supra, at 208); cf. Webster Eisenlohr, Inc. v. Kalodner, 145 F.2d 316, 320 (3d Cir. 1944), cert. denied, 325 U.S. 807 (1945). But cf. the early decisions, Duke of Bedford v. Ellis , A.C. 1; Sheffield Waterworks v. Yeomans, L.R. 2 Ch.App. 8 (1866); Brown v. Vermuden, 1 Ch.Cas. 272, 22 Eng.Rep. 796 (1676). The “spurious” action envisaged by original Rule 23 was in any event an anomaly because, although denominated a “class” action and pleaded as such, it was supposed not to adjudicate the rights or liabilities of any person not a party. It was believed to be an advantage of the “spurious” category that it would invite decisions that a member of the “class” could, like a member of the class in a “true” or “hybrid” action, intervene on an ancillary basis without being required to show an independent basis of Federal jurisdiction, and have the benefit of the date of the commencement of the action for purposes of the statute of limitations. See 3 Moore’s Federal Practice, pars. 23.10, 23.12 (2d ed. 1963). These results were attained in some instances but not in others. On the statute of limitations, see Union Carbide & Carbon Corp. v. Nisley, 300 F.2d 561 (10th Cir. 1961), pet. cert. dism., 371 U.S. 801 (1963); but cf. P. W. Husserl, Inc. v. Newman, 25 F.R.D. 264 (S.D.N.Y. 1960); Athas v. Day, 161 F.Supp. 916 (D.Colo. 1958). On ancillary intervention, see Amen v. Black, 234 F.2d 12 (10th Cir. 1956), cert. granted, 352 U.S. 888 (1956), dism. on stip., 355 U.S. 600 (1958); but. cf. Wagner v. Kemper, 13 F.R.D. 128 (W.D.Mo. 1952). The results, however, can hardly depend upon the mere appearance of a “spurious” category in the rule; they should turn no more basic considerations. See discussion of subdivision (c)(1) below. Finally, the original rule did not squarely address itself to the question of the measures that might be taken during the course of the action to assure procedural fairness, particularly giving notice to members of the class, which may in turn be related in some instances to the extension of the judgment to the class. See Chafee, supra, at 230-31; Keeffe, Levy & Donovan, supra; Developments in the Law, supra, 71 Harv.L.Rev. at 937-38; Note, Binding Effect of Class Actions, 67 Harv.L.Rev. 1059, 1062-65 (1954); Note, Federal Class Actions: A Suggested Revision of Rule 23, 46 Colum.L.Rev. 818, 833-36 (1946); Mich.Gen.Court R. 208.4 (effective Jan. 1, 1963); Idaho R.Civ.P. 23(d); Minn.R.Civ.P. 23.04; N.Dak.R.Civ.P. 23(d). The amended rule describes in more practical terms the occasions for maintaining class actions; provides that all class actions maintained to the end as such will result in judgments including those whom the court finds to be members of the class, whether or not the judgment is favorable to the class; and refers to the measures which can be taken to assure the fair conduct of these actions. Subdivision (a) states the prerequisites for maintaining any class action in terms of the numerousness of the class making joinder of the members impracticable, the existence of questions common to the class, and the desired qualifications of the representative parties. See Weinstein, Revision of Procedure; Some Problems in Class Actions, 9 Buffalo L.Rev. 433, 458-59 (1960); 2 Barron & Holtzoff, Federal Practice & Procedure § 562, at 265, § 572, at 351-52 (Wright ed. 1961). These are necessary but not sufficient conditions for a class action. See, e.g., Giordano v. Radio Corp. of Am., 183 F.2d 558, 560 (3d Cir. 1950); Zachman v. Erwin, 186 F.Supp. 681 (S.D.Tex. 1959); Baim & Blank, Inc. v. Warren Connelly Co., Inc., 19 F.R.D. 108 (S.D.N.Y. 1956). Subdivision (b) describes the additional elements which in varying situations justify the use of a class action. Subdivision (b)(1). The difficulties which would be likely to arise if resort were had to separate actions by or against the individual members of the class here furnish the reasons for, and the principal key to, the propriety and value of utilizing the class-action device. The considerations stated under clauses (A) and (B) are comparable to certain of the elements which define the persons whose joinder in an action is desirable as stated in Rule 19(a), as amended. See amended Rule 19(a)(2)(i) and (ii), and the Advisory Committee’s Note thereto; Hazard, Indispensable Party; The Historical Origin of a Procedural Phantom, 61 Colum.L.Rev. 1254, 1259-60 (1961); cf. 3 Moore, supra, par. 23.08, at 3435. Clause (A): One person may have rights against, or be under duties toward, numerous persons constituting a class, and be so positioned that conflicting or varying adjudications in lawsuits with individual members of the class might establish incompatible standards to govern his conduct. The class action device can be used effectively to obviate the actual or virtual dilemma which would thus confront the party opposing the class. The matter has been stated thus: “The felt necessity for a class action is greatest when the courts are called upon to order or sanction the alteration of the status quo in circumstances such that a large number of persons are in a position to call on a single person to alter the status quo, or to complain if it is altered, and the possibility exists that [the] actor might be called upon to act in inconsistent ways.” Louisell & Hazard, Pleading and Procedure; State and Federal 719 (1962); see Supreme Tribe of Ben-Hur v. Cauble, 255 U.S. 356, 366-67 (1921). To illustrate: Separate actions by individuals against a municipality to declare a bond issue invalid or condition or limit it, to prevent or limit the making of a particular appropriation or to compel or invalidate an assessment, might create a risk of inconsistent or varying determinations. In the same way, individual litigations of the rights and duties of riparian owners, or of landowners’ rights and duties respecting a claimed nuisance, could create a possibility of incompatible adjudications. Actions by or against a class provide a ready and fair means of achieving unitary adjudication. See Maricopa County Mun. Water Con. Dist. v. Looney, 219 F.2d 529 (9th Cir. 1955); Rank v. Krug, 142 F.Supp. 1, 154-59 (S.D.Calif. 1956), on app., State of California v. Rank, 293 F.2d 340, 348 (9th Cir. 1961); Gart v. Cole, 263 F.2d 244 (2d Cir. 1959), cert. denied 359 U.S. 978 (1959); cf. Martinez v. Maverick Cty. Water Con. & Imp. Dist., 219 F.2d 666 (5th Cir. 1955); 3 Moore, supra, par. 23.11, at 3458-59. Clause (B): This clause takes in situations where the judgment in a nonclass action by or against an individual member of the class, while not technically concluding the other members, might do so as a practical matter. The vice of an individual actions would lie in the fact that the other members of the class, thus practically concluded, would have had no representation in the lawsuit. In an action by policy holders against a fraternal benefit association attacking a financial reorganization of the society, it would hardly have been practical, if indeed it would have been possible, to confine the effects of a validation of the reorganization to the individual plaintiffs. Consequently a class action was called for with adequate representation of all members of the class. See Supreme Tribe of Ben-Hur v. Cauble, 255 U.S. 356 (1921); Waybright v. Columbian Mut. Life Ins. Co., 30 F.Supp. 885 (W.D.Tenn. 1939); cf. Smith v. Swormstedt, 16 How. (57 U.S.) 288 (1853). For much the same reason actions by shareholders to compel the declaration of a dividend the proper recognition and handling of redemption or pre-emption rights, or the like (or actions by the corporation for corresponding declarations of rights), should ordinarily be conducted as class actions, although the matter has been much obscured by the insistence that each shareholder has an individual claim. See Knapp v. Bankers Securities Corp., 17 F.R.D. 245 (E.D.Pa. 1954), aff’d, 230 F.2d 717 (3d Cir. 1956); Giesecke v. Denver Tramway Corp., 81 F.Supp. 957 (D.Del. 1949); Zahn v. Transamerica Corp., 162 F.2d 36 (3d Cir. 1947); Speed v. Transamerica Corp., 100 F.Supp. 461 (D.Del. 1951); Sobel v. Whittier Corp., 95 F.Supp. 643 (E.D.Mich. 1951), app. dism., 195 F.2d 361 (6th Cir. 1952); Goldberg v. Whittier Corp., 111 F.Supp. 382 (E.D.Mich. 1953); Dann v. Studebaker-Packard Corp., 288 F.2d 201 (6th Cir. 1961); Edgerton v. Armour & Co.,94 F.Supp. 549 (S.D.Calif. 1950); Ames v. Mengel Co., 190 F.2d 344 (2d Cir. 1951). (These shareholders’ actions are to be distinguished from derivative actions by shareholders dealt with in new Rule 23.1). The same reasoning applies to an action which charges a breach of trust by an indenture trustee or other fiduciary similarly affecting the members of a large class of security holders or other beneficiaries, and which requires an accounting or like measures to restore the subject of the trust. See Bosenberg v. Chicago T. & T. Co., 128 F.2d 245 (7th Cir. 1942); Citizens Banking Co. v. Monticello State Bank, 143 F.2d 261 (8th Cir. 1944); Redmond v. Commerce Trust Co., 144 F.2d 140 (8th Cir. 1944), cert. denied, 323 U.S. 776 (1944); cf. York v. Guaranty Trust Co., 143 F.2d 503 (2d Cir. 1944), rev’d on grounds not here relevant, 326 U.S. 99 (1945). In various situations an adjudication as to one or more members of the class will necessarily or probably have an adverse practical effect on the interests of other members who should therefore be represented in the lawsuit. This is plainly the case when claims are made by numerous persons against a fund insufficient to satisfy all claims. A class action by or against representative members to settle the validity of the claims as a whole, or in groups, followed by separate proof of the amount of each valid claim and proportionate distribution of the fund, meets the problem. Cf. Dickinson v. Burnham, 197 F.2d 973 (2d Cir. 1952), cert. denied, 344 U.S. 875 (1952); 3 Moore, supra, at par. 23.09. The same reasoning applies to an action by a creditor to set aside a fraudulent conveyance by the debtor and to appropriate the property to his claim, when the debtor’s assets are insufficient to pay all creditors’ claims. See Hefferman v. Bennett & Armour, 110 Cal.App.2d 564, 243 P.2d 846 (1952); cf. City & County of San Francisco v. Market Street Ry., 95 Cal.App.2d 648, 213 P.2d 780 (1950). Similar problems, however, can arise in the absence of a fund either present or potential. A negative or mandatory injunction secured by one of a numerous class may disable the opposing party from performing claimed duties toward the other members of the class or materially affect his ability to do so. An adjudication as to movie “clearances and runs” nominally affecting only one exhibitor would often have practical effects on all the exhibitors in the same territorial area. Cf. United States v. Paramount Pictures, Inc., 66 F.Supp. 323, 341-46 (S.D.N.Y. 1946); 334 U.S. 131, 144-48 (1948). Assuming a sufficiently numerous class of exhibitors, a class action would be advisable. (Here representation of subclasses of exhibitors could become necessary; see subdivision (c)(3)(B).) Subdivision (b)(2). This subdivision is intended to reach situations where a party has taken action or refused to take action with respect to a class, and final relief of an injunctive nature or of a corresponding declaratory nature, settling the legality of the behavior with respect to the class as a whole, is appropriate. Declaratory relief “corresponds” to injunctive relief when as a practical matter it affords injunctive relief or serves as a basis for later injunctive relief. The subdivision does not extend to cases in which the appropriate final relief relates exclusively or predominantly to money damages. Action or inaction is directed to a class within the meaning of this subdivision even if it has taken effect or is threatened only as to one or a few members of the class, provided it is based on grounds which have general application to the class. Illustrative are various actions in the civil-rights field where a party is charged with discriminating unlawfully against a class, usually one whose members are incapable of specific enumeration. See Potts v. Flax, 313 F.2d 284 (5th Cir. 1963); Bailey v. Patterson, 323 F.2d 201 (5th Cir. 1963), cert. denied, 377 U.S. 972 (1964); Brunson v. Board of Trustees of School District No. 1, Clarendon City, S.C., 311 F.2d 107 (4th Cir. 1962), cert. denied, 373 U.S. 933 (1963); Green v. School Bd. of Roanoke, Va., 304 F.2d 118 (4th Cir. 1962); Orleans Parish School Bd. v. Bush, 242 F.2d 156 (5th Cir. 1957), cert. denied, 354 U.S. 921 (1957); Mannings v. Board of Public Inst. of Hillsborough County, Fla., 277 F.2d 370 (5th Cir. 1960); Northcross v. Board of Ed. of City of Memphis, 302 F.2d 818 (6th Cir. 1962), cert. denied 370 U.S. 944 (1962); Frasier v. Board of Trustees of Univ. of N.C., 134 F.Supp. 589 (M.D.N.C. 1955, 3-judge court), aff’d, 350 U.S. 979 (1956). Subdivision (b)(2) is not limited to civil-rights cases. Thus an action looking to specific or declaratory relief could be brought by a numerous class of purchasers, say retailers of a given description, against a seller alleged to have undertaken to sell to that class at prices higher than those set for other purchasers, say retailers of another description, when the applicable law forbids such a pricing differential. So also a patentee of a machine, charged with selling or licensing the machine on condition that purchasers or licensees also purchase or obtain licenses to use an ancillary unpatented machine, could be sued on a class basis by a numerous group of purchasers or licensees, or by a numerous group of competing sellers or licensors of the unpatented machine, to test the legality of the “tying” condition. Subdivision (b)(3). In the situations to which this subdivision relates, class-action treatment is not as clearly called for as in those described above, but it may nevertheless be convenient and desirable depending upon the particular facts. Subdivision (b)(3) encompasses those cases in which a class action would achieve economies of time, effort, and expense, and promote, uniformity of decision as to persons similarly situated, without sacrificing procedural fairness or bringing about other undesirable results. Cf. Chafee, supra, at 201. The court is required to find, as a condition of holding that a class action may be maintained under this subdivision, that the questions common to the class predominate over the questions affecting individual members. It is only where this predominance exists that economies can be achieved by means of the class-action device. In this view, a fraud perpetrated on numerous persons by the use of similar misrepresentations may be an appealing situation for a class action, and it may remain so despite the need, if liability is found, for separate determination of the damages suffered by individuals within the class. On the other hand, although having some common core, a fraud case may be unsuited for treatment as a class action if there was material variation in the representation made or in the kinds or degrees of reliance by the persons to whom they were addressed. See Oppenheimer v. F. J. Young & Co., Inc., 144 F.2d 387 (2d Cir. 1944); Miller v. National City Bank of N.Y., 166 F.2d 723 (2d Cir. 1948); and for like problems in other contexts, see Hughes v. Encyclopaedia Brittanica, 199 F.2d 295 (7th Cir. 1952); Sturgeon v. Great Lakes Steel Corp., 143 F.2d 819 (6th Cir. 1944). A “mass accident” resulting in injuries to numerous persons is ordinarily not appropriate for a class action because of the likelihood that significant questions, not only of damages but of liability and defenses of liability, would be present, affecting the individuals in different ways. In these circumstances an action conducted nominally as a class action would degenerate in practice into multiple lawsuits separately tried. See Pennsylvania R.R. v. United States, 111 F.Supp. 80 (D.N.J. 1953); cf. Weinstein, supra, 9 Buffalo L.Rev. at 469. Private damage claims by numerous individuals arising out of concerted antitrust violations may or may not involve predominating common questions. See Union Carbide & Carbon Corp. v. Nisley, 300 F.2d 561 (10th Cir. 1961), pet. cert. dism., 371 U.S. 801 (1963); cf. Weeks v. Bareco Oil Co., 125 F.2d 84 (7th Cir. 1941); Kainz v. Anheuser-Busch, Inc., 194 F.2d 737 (7th Cir. 1952); Hess v. Anderson, Clayton & Co., 20 F.R.D. 466 (S.D.Calif. 1957). That common questions predominate is not itself sufficient to justify a class action under subdivision (b)(3), for another method of handling the litigious situation may be available which has greater practical advantages. Thus one or more actions agreed to by the parties as test or model actions may be preferable to a class action; or it may prove feasible and preferable to consolidate actions. Cf. Weinstein, supra, 9 Buffalo L.Rev. at 438-54. Even when a number of separate actions are proceeding simultaneously, experience shows that the burdens on the parties and the courts can sometimes be reduced by arrangements for avoiding repetitious discovery or the like. Currently the Coordinating Committee on Multiple Litigation in the United States District Courts (a subcommittee of the Committee on Trial Practice and Technique of the Judicial Conference of the United States) is charged with developing methods for expediting such massive litigation. To reinforce the point that the court with the aid of the parties ought to assess the relative advantages of alternative procedures for handling the total controversy, subdivision (b)(3) requires, as a further condition of maintaining the class action, that the court shall find that that procedure is “superior” to the others in the particular circumstances. Factors (A)-(D) are listed, non-exhaustively, as pertinent to the findings. The court is to consider the interests of individual members of the class in controlling their own litigations and carrying them on as they see fit. See Weeks v. Bareco Oil Co., 125 F.2d 84, 88-90, 93-94 (7th Cir. 1941) (anti-trust action); see also Pentland v. Dravo Corp., 152 F.2d 851 (3d Cir. 1945), and Chaffee, supra, at 273-75, regarding policy of Fair Labor Standards Act of 1938, § 16(b), 29 U.S.C. § 216(b), prior to amendment by Portal-to-Portal Act of 1947, § 5(a). [The present provisions of 29 U.S.C. § 216(b) are not intended to be affected by Rule 23, as amended.] In this connection the court should inform itself of any litigation actually pending by or against the individuals. The interests of individuals in conducting separate lawsuits may be so strong as to call for denial of a class action. On the other hand, these interests may be theoretic rather than practical; the class may have a high degree of cohesion and prosecution of the action through representatives would be quite unobjectionable, or the amounts at stake for individuals may be so small that separate suits would be impracticable. The burden that separate suits would impose on the party opposing the class, or upon the court calendars, may also fairly be considered. (See the discussion, under subdivision (c)(2) below, of the right of members to be excluded from the class upon their request.) Also pertinent is the question of the desirability of concentrating the trial of the claims in the particular forum by means of a class action, in contrast to allowing the claims to be litigated separately in forums to which they would ordinarily be brought. Finally, the court should consider the problems of management which are likely to arise in the conduct of a class action. Subdivision (c)(1). In order to give clear definition to the action, this provision requires the court to determine, as early in the proceedings as may be practicable, whether an action brought as a class action is to be so maintained. The determination depends in each case on satisfaction of the terms of subdivision (a) and the relevant provisions of subdivision (b). An order embodying a determination can be conditional; the court may rule, for example, that a class action may be maintained only if the representation is improved through intervention of additional parties of a stated type. A determination once made can be altered or amended before the decision on the merits if, upon fuller development of the facts, the original determination appears unsound. A negative determination means that the action should be stripped of its character as a class action. See subdivision (d)(4). Although an action thus becomes a nonclass action, the court may still be receptive to interventions before the decision on the merits so that the litigation may cover as many interests as can be conveniently handled; the questions whether the intervenors in the nonclass action shall be permitted to claim “ancillary” jurisdiction or the benefit of the date of the commencement of the action for purposes of the statute of limitations are to be decided by reference to the laws governing jurisdiction and limitations as they apply in particular contexts. Whether the court should require notice to be given to members of the class of its intention to make a determination, or of the order embodying it, is left to the court’s discretion under subdivision (d)(2). Subdivision (c)(2) makes special provision for class actions maintained under subdivision (b)(3). As noted in the discussion of the latter subdivision, the interests of the individuals in pursuing their own litigations may be so strong here as to warrant denial of a class action altogether. Even when a class action is maintained under subdivision (b)(3), this individual interest is respected. Thus the court is required to direct notice to the members of the class of the right of each member to be excluded from the class upon his request. A member who does not request exclusion may, if he wishes, enter an appearance in the action through his counsel; whether or not he does so, the judgment in the action will embrace him. The notice setting forth the alternatives open to the members of the class, is to be the best practicable under the circumstances, and shall include individual notice to the members who can be identified through reasonable effort. (For further discussion of this notice, see the statement under subdivision (d)(2) below.) Subdivision (c)(3). The judgment in a class action maintained as such to the end will embrace the class, that is, in a class action under subdivision (b)(1) or (b)(2), those found by the court to be class members; in a class action under subdivision (b)(3), those to whom the notice prescribed by subdivision (c)(2) was directed, excepting those who requested exclusion or who are ultimately found by the court not to be members of the class. The judgment has this scope whether it is favorable or unfavorable to the class. In a (b)(1) or (b)(2) action the judgment “describes” the members of the class, but need not specify the individual members; in a (b)(3) action the judgment “specifies” the individual members who have been identified and described the others. Compare subdivision (c)(4) as to actions conducted as class actions only with respect to particular issues. Where the class-action character of the lawsuit is based solely on the existence of a “limited fund,” the judgment, while extending to all claims of class members against the fund, has ordinarily left unaffected the personal claims of nonappearing members against the debtor. See 3 Moore, supra, par. 23.11. Hitherto, in a few actions conducted as “spurious” class actions and thus nominally designed to extend only to parties and others intervening before the determination of liability, courts have held or intimated that class members might be permitted to intervene after a decision on the merits favorable to their interests, in order to secure the benefits of the decision for themselves, although they would presumably be unaffected by an unfavorable decision. See, as to the propriety of this so-called “one-way” intervention in “spurious” actions, the conflicting views expressed in Union Carbide & Carbon Corp. v. Nisley, 300 F.2d 561 (10th Cir. 1961), pet. cert. dism., 371 U.S. 801 (1963); York v. Guaranty Trust Co., 143 F.2d 503, 529 (2d Cir. 1944), rev’d on grounds not here relevant, 326 U.S. 99 (1945); Pentland v. Dravo Corp., 152 F.2d 851, 856 (3d Cir. 1945); Speed v. Transamerica Corp., 100 F.Supp. 461, 463 (D.Del. 1951); State Wholesale Grocers v. Great Atl. & Pac. Tea Co., 24 F.R.D. 510 (N.D.Ill. 1959); Alabama Ind. Serv. Stat. Assn. v. Shell Pet Corp., 28 F.Supp. 386, 390 (N.D.Ala. 1939); Tolliver v. Cudahy Packing Co., 39 F.Supp. 337, 339 (E.D.Tenn. 1941); Kalven & Rosenfield, supra, 8 U. of Chi.L.Rev. 684 (1941); Comment, 53 Nw.U.L.Rev. 627, 632-33 (1958); Developments in the Law, supra, 71 Harv.L.Rev. at 935; 2 Barron & Holtzoff, supra, § 568; but cf. Lockwood v. Hercules Powder Co., 7 F.R.D. 24, 28-29 (W.D.Mo. 1947); Abram v. San Joaquin Cotton Oil Co., 46 F.Supp. 969, 976-77 (S.D.Calif. 1942); Chaffee, supra, at 280, 285; 3 Moore, supra, par. 23.12, at 3476. Under proposed subdivision (c)(3), one-way intervention is excluded; the action will have been early determined to be a class or nonclass action, and in the former case the judgment, whether or not favorable, will include the class, as above stated. Although thus declaring that the judgment in a class action includes the class, as defined, subdivision (c)(3) does not disturb the recognized principle that the court conducting the action cannot predetermine the res judicata effect of the judgment; this can be tested only in a subsequent action. See Restatement, Judgments § 86, comment (h), § 116 (1942). The court, however, in framing the judgment in any suit brought as a class action, must decide what its extent or coverage shall be, and if the matter is carefully considered, questions of res judicata are less likely to be raised at a later time and if raised will be more satisfactorily answered. See Chafee, supra, at 294; Weinstein, supra, 9 Buffalo L.Rev. at 460. Subdivision (c)(4). This provision recognizes that an action may be maintained as a class action as to particular issues only. For example, in a fraud or similar case the action may retain its “class” character only through the adjudication of liability to the class; the members of the class may thereafter be required to come in individually and prove the amounts of their respective claims. Two or more classes may be represented in a single action. Where a class is found to include subclasses divergent in interest, the class may be divided correspondingly, and each subclass treated as a class. Subdivision (d) is concerned with the fair and efficient conduct of the action and lists some types of orders which may be appropriate. The court should consider how the proceedings are to be arranged in sequence, and what measures should be taken to simplify the proof and argument. See subdivision (d)(1). The orders resulting from this consideration, like the others referred to in subdivision (d), may be combined with a pretrial order under Rule 16, and are subject to modification as the case proceeds. Subdivision (d)(2) sets out a non-exhaustive list of possible occasions for orders requiring notice to the class. Such notice is not a novel conception. For example, in “limited fund” cases, members of the class have been notified to present individual claims after the basic class decision. Notice has gone to members of a class so that they might express any opposition to the representation, see United States v. American Optical Co., 97 F.Supp. 66 (N.D.Ill. 1951), and 1950-51 CCH Trade Cases 64573-74 (par. 62869); cf. Weeks v. Bareco Oil Co., 125 F.2d 84, 94 (7th Cir. 1941), and notice may encourage interventions to improve the representation of the class. Cf. Oppenheimer v. F. J. Young & Co., 144 F.2d 387 (2d Cir. 1944). Notice has been used to poll members on a proposed modification of a consent decree. See record in Sam Fox Publishing Co. v. United States, 366 U.S. 683 (1961). Subdivision (d)(2) does not require notice at any stage, but rather calls attention to its availability and invokes the court’s discretion. In the degree that there is cohesiveness or unity in the class and the representation is effective, the need for notice to the class will tend toward a minimum. These indicators suggest that notice under subdivision (d)(2) may be particularly useful and advisable in certain class actions maintained under subdivision (b)(3), for example, to permit members of the class to object to the representation. Indeed, under subdivision (c)(2), notice must be ordered, and is not merely discretionary, to give the members in a subdivision (b)(3) class action an opportunity to secure exclusion from the class. This mandatory notice pursuant to subdivision (c)(2), together with any discretionary notice which the court may find it advisable to give under subdivision (d)(2), is designed to fulfill requirements of due process to which the class action procedure is of course subject. See Hansberry v. Lee, 311 U.S. 32 (1940); Mullane v. Central Hanover Bank & Trust Co., 339 U.S. 306 (1950); cf. Dickinson v. Burnham, 197 F.2d 973, 979 (2d Cir. 1952), and studies cited at 979 n. 4; see also All American Airways, Inc. v. Elderd, 209 F.2d 247, 249 (2d Cir. 1954); Gart v. Cole, 263 F.2d 244, 248-49 (2d Cir. 1959), cert. denied, 359 U.S. 978 (1959). Notice to members of the class, whenever employed under amended Rule 23, should be accommodated to the particular purpose but need not comply with the formalities for service of process. See Chafee, supra, at 230-31; Brendle v. Smith, 7 F.R.D. 119 (S.D.N.Y. 1946). The fact that notice is given at one stage of the action does not mean that it must be given at subsequent stages. Notice is available fundamentally “for the protection of the members of the class or otherwise for the fair conduct of the action” and should not be used merely as a device for the undesirable solicitation of claims. See the discussion in Cherner v. Transitron Electronic Corp., 201 F.Supp. 934 (D.Mass. 1962); Hormel v. United States, 17 F.R.D. 303 (S.D.N.Y. 1955). In appropriate cases the court should notify interested government agencies of the pendency of the action or of particular steps therein. Subdivision (d)(3) reflects the possibility of conditioning the maintenance of a class action, e.g., on the strengthening of the representation, see subdivision (c)(1) above; and recognizes that the imposition of conditions on intervenors may be required for the proper and efficient conduct of the action. As to orders under subdivision (d)(4), see subdivision (c)(1) above. Subdivision (e) requires approval of the court, after notice, for the dismissal or compromise of any class action. The amendments are technical. No substantive change is intended. Subdivision (f). This permissive interlocutory appeal provision is adopted under the power conferred by 28 U.S.C. § 1292(e). Appeal from an order granting or denying class certification is permitted in the sole discretion of the court of appeals. No other type of Rule 23 order is covered by this provision. The court of appeals is given unfettered discretion whether to permit the appeal, akin to the discretion exercised by the Supreme Court in acting on a petition for certiorari. This discretion suggests an analogy to the provision in 28 U.S.C. § 1292(b) for permissive appeal on certification by a district court. Subdivision (f), however, departs from the § 1292(b) model in two significant ways. It does not require that the district court certify the certification ruling for appeal, although the district court often can assist the parties and court of appeals by offering advice on the desirability of appeal. And it does not include the potentially limiting requirements of § 1292(b) that the district court order “involve a controlling question of law as to which there is substantial ground for difference of opinion and that an immediate appeal from the order may materially advance the ultimate termination of the litigation.” The courts of appeals will develop standards for granting review that reflect the changing areas of uncertainty in class litigation. The Federal Judicial Center study supports the view that many suits with class-action allegations present familiar and almost routine issues that are no more worthy of immediate appeal than many other interlocutory rulings. Yet several concerns justify expansion of present opportunities to appeal. An order denying certification may confront the plaintiff with a situation in which the only sure path to appellate review is by proceeding to final judgment on the merits of an individual claim that, standing alone, is far smaller than the costs of litigation. An order granting certification, on the other hand, may force a defendant to settle rather than incur the costs of defending a class action and run the risk of potentially ruinous liability. These concerns can be met at low cost by establishing in the court of appeals a discretionary power to grant interlocutory review in cases that show appeal-worthy certification issues. Permission to appeal may be granted or denied on the basis of any consideration that the court of appeals finds persuasive. Permission is most likely to be granted when the certification decision turns on a novel or unsettled question of law, or when, as a practical matter, the decision on certification is likely dispositive of the litigation. The district court, having worked through the certification decision, often will be able to provide cogent advice on the factors that bear on the decision whether to permit appeal. This advice can be particularly valuable if the certification decision is tentative. Even as to a firm certification decision, a statement of reasons bearing on the probable benefits and costs of immediate appeal can help focus the court of appeals decision, and may persuade the disappointed party that an attempt to appeal would be fruitless. The 10-day period for seeking permission to appeal is designed to reduce the risk that attempted appeals will disrupt continuing proceedings. It is expected that the courts of appeals will act quickly in making the preliminary determination whether to permit appeal. Permission to appeal does not stay trial court proceedings. A stay should be sought first from the trial court. If the trial court refuses a stay, its action and any explanation of its views should weigh heavily with the court of appeals. Appellate Rule 5 has been modified to establish the procedure for petitioning for leave to appeal under subdivision (f). Changes Made after Publication (GAP Report). No changes were made in the text of Rule 23(f) as published. Several changes were made in the published Committee Note. (1) References to 28 U.S.C. § 1292(b) interlocutory appeals were revised to dispel any implication that the restrictive elements of § 1292(b) should be read in to Rule 23(f). New emphasis was placed on court of appeals discretion by making explicit the analogy to certiorari discretion. (2) Suggestions that the new procedure is a “modest” expansion of appeal opportunities, to be applied with “restraint,” and that permission “almost always will be denied when the certification decision turns on case-specific matters of fact and district court discretion,” were deleted. It was thought better simply to observe that courts of appeals will develop standards “that reflect the changing areas of uncertainty in class litigation.” Subdivision (c). Subdivision (c) is amended in several respects. The requirement that the court determine whether to certify a class “as soon as practicable after commencement of an action” is replaced by requiring determination “at an early practicable time.” The notice provisions are substantially revised. Paragraph (1). Subdivision (c)(1)(A) is changed to require that the determination whether to certify a class be made “at an early practicable time.” The “as soon as practicable” exaction neither reflects prevailing practice nor captures the many valid reasons that may justify deferring the initial certification decision. See Willging, Hooper & Niemic, Empirical Study of Class Actions in Four Federal District Courts: Final Report to the Advisory Committee on Civil Rules 26-36 (Federal Judicial Center 1996). Time may be needed to gather information necessary to make the certification decision. Although an evaluation of the probable outcome on the merits is not properly part of the certification decision, discovery in aid of the certification decision often includes information required to identify the nature of the issues that actually will be presented at trial. In this sense it is appropriate to conduct controlled discovery into the “merits,” limited to those aspects relevant to making the certification decision on an informed basis. Active judicial supervision may be required to achieve the most effective balance that expedites an informed certification determination without forcing an artificial and ultimately wasteful division between “certification discovery” and “merits discovery.” A critical need is to determine how the case will be tried. An increasing number of courts require a party requesting class certification to present a “trial plan” that describes the issues likely to be presented at trial and tests whether they are susceptible of class-wide proof. See Manual For Complex Litigation Third, § 21.213, p. 44; § 30.11, p. 214; § 30.12, p. 215. Other considerations may affect the timing of the certification decision. The party opposing the class may prefer to win dismissal or summary judgment as to the individual plaintiffs without certification and without binding the class that might have been certified. Time may be needed to explore designation of class counsel under Rule 23(g), recognizing that in many cases the need to progress toward the certification determination may require designation of interim counsel under Rule 23(g)(2)(A). Although many circumstances may justify deferring the certification decision, active management may be necessary to ensure that the certification decision is not unjustifiably delayed. Subdivision (c)(1)(C) reflects two amendments. The provision that a class certification “may be conditional” is deleted. A court that is not satisfied that the requirements of Rule 23 have been met should refuse certification until they have been met. The provision that permits alteration or amendment of an order granting or denying class certification is amended to set the cut-off point at final judgment rather than “the decision on the merits.” This change avoids the possible ambiguity in referring to “the decision on the merits.” Following a determination of liability, for example, proceedings to define the remedy may demonstrate the need to amend the class definition or subdivide the class. In this setting the final judgment concept is pragmatic. It is not the same as the concept used for appeal purposes, but it should be flexible, particularly in protracted litigation. The authority to amend an order under Rule 23(c)(1) before final judgment does not restore the practice of “one-way intervention” that was rejected by the 1966 revision of Rule 23. A determination of liability after certification, however, may show a need to amend the class definition. Decertification may be warranted after further proceedings. If the definition of a class certified under Rule 23(b)(3) is altered to include members who have not been afforded notice and an opportunity to request exclusion, notice—including an opportunity to request exclusion—must be directed to the new class members under Rule 23(c)(2)(B). Paragraph (2). The first change made in Rule 23(c)(2) is to call attention to the court’s authority—already established in part by Rule 23(d)(2)—to direct notice of certification to a Rule 23(b)(1) or (b)(2) class. The present rule expressly requires notice only in actions certified under Rule 23(b)(3). Members of classes certified under Rules 23(b)(1) or (b)(2) have interests that may deserve protection by notice. The authority to direct notice to class members in a (b)(1) or (b)(2) class action should be exercised with care. For several reasons, there may be less need for notice than in a (b)(3) class action. There is no right to request exclusion from a (b)(1) or (b)(2) class. The characteristics of the class may reduce the need for formal notice. The cost of providing notice, moreover, could easily cripple actions that do not seek damages. The court may decide not to direct notice after balancing the risk that notice costs may deter the pursuit of class relief against the benefits of notice. When the court does direct certification notice in a (b)(1) or (b)(2) class action, the discretion and flexibility established by subdivision (c)(2)(A) extend to the method of giving notice. Notice facilitates the opportunity to participate. Notice calculated to reach a significant number of class members often will protect the interests of all. Informal methods may prove effective. A simple posting in a place visited by many class members, directing attention to a source of more detailed information, may suffice. The court should consider the costs of notice in relation to the probable reach of inexpensive methods. If a Rule 23(b)(3) class is certified in conjunction with a (b)(2) class, the (c)(2)(B) notice requirements must be satisfied as to the (b)(3) class. The direction that class-certification notice be couched in plain, easily understood language is a reminder of the need to work unremittingly at the difficult task of communicating with class members. It is difficult to provide information about most class actions that is both accurate and easily understood by class members who are not themselves lawyers. Factual uncertainty, legal complexity, and the complication of class-action procedure raise the barriers high. The Federal Judicial Center has created illustrative clear-notice forms that provide a helpful starting point for actions similar to those described in the forms. Subdivision (e). Subdivision (e) is amended to strengthen the process of reviewing proposed class-action settlements. Settlement may be a desirable means of resolving a class action. But court review and approval are essential to assure adequate representation of class members who have not participated in shaping the settlement. Paragraph (1). Subdivision (e)(1)(A) expressly recognizes the power of a class representative to settle class claims, issues, or defenses. Rule 23(e)(1)(A) resolves the ambiguity in former Rule 23(e)’s reference to dismissal or compromise of “a class action.” That language could be—and at times was—read to require court approval of settlements with putative class representatives that resolved only individual claims. See Manual for Complex Litigation Third, § 30.41. The new rule requires approval only if the claims, issues, or defenses of a certified class are resolved by a settlement, voluntary dismissal, or compromise. Subdivision (e)(1)(B) carries forward the notice requirement of present Rule 23(e) when the settlement binds the class through claim or issue preclusion; notice is not required when the settlement binds only the individual class representatives. Notice of a settlement binding on the class is required either when the settlement follows class certification or when the decisions on certification and settlement proceed simultaneously. Reasonable settlement notice may require individual notice in the manner required by Rule 23(c)(2)(B) for certification notice to a Rule 23(b)(3) class. Individual notice is appropriate, for example, if class members are required to take action—such as filing claims—to participate in the judgment, or if the court orders a settlement opt-out opportunity under Rule 23(e)(3). Subdivision (e)(1)(C) confirms and mandates the already common practice of holding hearings as part of the process of approving settlement, voluntary dismissal, or compromise that would bind members of a class. Subdivision (e)(1)(C) states the standard for approving a proposed settlement that would bind class members. The settlement must be fair, reasonable, and adequate. A helpful review of many factors that may deserve consideration is provided by In re: Prudential Ins. Co. America Sales Practice Litigation Agent Actions, 148 F.3d 283, 316-324 (3d Cir. 1998). Further guidance can be found in the Manual for Complex Litigation. The court must make findings that support the conclusion that the settlement is fair, reasonable, and adequate. The findings must be set out in sufficient detail to explain to class members and the appellate court the factors that bear on applying the standard. Settlement review also may provide an occasion to review the cogency of the initial class definition. The terms of the settlement themselves, or objections, may reveal divergent interests of class members and demonstrate the need to redefine the class or to designate subclasses. Redefinition of a class certified under Rule 23(b)(3) may require notice to new class members under Rule 23(c)(2)(B). See Rule 23(c)(1)(C). Paragraph (2). Subdivision (e)(2) requires parties seeking approval of a settlement, voluntary dismissal, or compromise under Rule 23(e)(1) to file a statement identifying any agreement made in connection with the settlement. This provision does not change the basic requirement that the parties disclose all terms of the settlement or compromise that the court must approve under Rule 23(e)(1). It aims instead at related undertakings that, although seemingly separate, may have influenced the terms of the settlement by trading away possible advantages for the class in return for advantages for others. Doubts should be resolved in favor of identification. Further inquiry into the agreements identified by the parties should not become the occasion for discovery by the parties or objectors. The court may direct the parties to provide to the court or other parties a summary or copy of the full terms of any agreement identified by the parties. The court also may direct the parties to provide a summary or copy of any agreement not identified by the parties that the court considers relevant to its review of a proposed settlement. In exercising discretion under this rule, the court may act in steps, calling first for a summary of any agreement that may have affected the settlement and then for a complete version if the summary does not provide an adequate basis for review. A direction to disclose a summary or copy of an agreement may raise concerns of confidentiality. Some agreements may include information that merits protection against general disclosure. And the court must provide an opportunity to claim work-product or other protections. Paragraph (3). Subdivision (e)(3) authorizes the court to refuse to approve a settlement unless the settlement affords class members a new opportunity to request exclusion from a class certified under Rule 23(b)(3) after settlement terms are known. An agreement by the parties themselves to permit class members to elect exclusion at this point by the settlement agreement may be one factor supporting approval of the settlement. Often there is an opportunity to opt out at this point because the class is certified and settlement is reached in circumstances that lead to simultaneous notice of certification and notice of settlement. In these cases, the basic opportunity to elect exclusion applies without further complication. In some cases, particularly if settlement appears imminent at the time of certification, it may be possible to achieve equivalent protection by deferring notice and the opportunity to elect exclusion until actual settlement terms are known. This approach avoids the cost and potential confusion of providing two notices and makes the single notice more meaningful. But notice should not be delayed unduly after certification in the hope of settlement. Rule 23(e)(3) authorizes the court to refuse to approve a settlement unless the settlement affords a new opportunity to elect exclusion in a case that settles after a certification decision if the earlier opportunity to elect exclusion provided with the certification notice has expired by the time of the settlement notice. A decision to remain in the class is likely to be more carefully considered and is better informed when settlement terms are known. The opportunity to request exclusion from a proposed settlement is limited to members of a (b)(3) class. Exclusion may be requested only by individual class members; no class member may purport to opt out other class members by way of another class action. The decision whether to approve a settlement that does not allow a new opportunity to elect exclusion is confided to the court’s discretion. The court may make this decision before directing notice to the class under Rule 23(e)(1)(B) or after the Rule 23(e)(1)(C) hearing. Many factors may influence the court’s decision. Among these are changes in the information available to class members since expiration of the first opportunity to request exclusion, and the nature of the individual class members’ claims. The terms set for permitting a new opportunity to elect exclusion from the proposed settlement of a Rule 23(b)(3) class action may address concerns of potential misuse. The court might direct, for example, that class members who elect exclusion are bound by rulings on the merits made before the settlement was proposed for approval. Still other terms or conditions may be appropriate. Paragraph (4). Subdivision (e)(4) confirms the right of class members to object to a proposed settlement, voluntary dismissal, or compromise. The right is defined in relation to a disposition that, because it would bind the class, requires court approval under subdivision (e)(1)(C). Subdivision (e)(4)(B) requires court approval for withdrawal of objections made under subdivision (e)(4)(A). Review follows automatically if the objections are withdrawn on terms that lead to modification of the settlement with the class. Review also is required if the objector formally withdraws the objections. If the objector simply abandons pursuit of the objection, the court may inquire into the circumstances. Approval under paragraph (4)(B) may be given or denied with little need for further inquiry if the objection and the disposition go only to a protest that the individual treatment afforded the objector under the proposed settlement is unfair because of factors that distinguish the objector from other class members. Different considerations may apply if the objector has protested that the proposed settlement is not fair, reasonable, or adequate on grounds that apply generally to a class or subclass. Such objections, which purport to represent class-wide interests, may augment the opportunity for obstruction or delay. If such objections are surrendered on terms that do not affect the class settlement or the objector’s participation in the class settlement, the court often can approve withdrawal of the objections without elaborate inquiry. Once an objector appeals, control of the proceeding lies in the court of appeals. The court of appeals may undertake review and approval of a settlement with the objector, perhaps as part of appeal settlement procedures, or may remand to the district court to take advantage of the district court’s familiarity with the action and settlement. Subdivision (g). Subdivision (g) is new. It responds to the reality that the selection and activity of class counsel are often critically important to the successful handling of a class action. Until now, courts have scrutinized proposed class counsel as well as the class representative under Rule 23(a)(4). This experience has recognized the importance of judicial evaluation of the proposed lawyer for the class, and this new subdivision builds on that experience rather than introducing an entirely new element into the class certification process. Rule 23(a)(4) will continue to call for scrutiny of the proposed class representative, while this subdivision will guide the court in assessing proposed class counsel as part of the certification decision. This subdivision recognizes the importance of class counsel, states the obligation to represent the interests of the class, and provides a framework for selection of class counsel. The procedure and standards for appointment vary depending on whether there are multiple applicants to be class counsel. The new subdivision also provides a method by which the court may make directions from the outset about the potential fee award to class counsel in the event the action is successful. Paragraph (1) sets out the basic requirement that class counsel be appointed if a class is certified and articulates the obligation of class counsel to represent the interests of the class, as opposed to the potentially conflicting interests of individual class members. It also sets out the factors the court should consider in assessing proposed class counsel. Paragraph (1)(A) requires that the court appoint class counsel to represent the class. Class counsel must be appointed for all classes, including each subclass that the court certifies to represent divergent interests. Paragraph (1)(A) does not apply if “a statute provides otherwise.” This recognizes that provisions of the Private Securities Litigation Reform Act of 1995, Pub. L. No. 104-67, 109 Stat. 737 (1995) (codified in various sections of 15 U.S.C.), contain directives that bear on selection of a lead plaintiff and the retention of counsel. This subdivision does not purport to supersede or to affect the interpretation of those provisions, or any similar provisions of other legislation. Paragraph 1(B) recognizes that the primary responsibility of class counsel, resulting from appointment as class counsel, is to represent the best interests of the class. The rule thus establishes the obligation of class counsel, an obligation that may be different from the customary obligations of counsel to individual clients. Appointment as class counsel means that the primary obligation of counsel is to the class rather than to any individual members of it. The class representatives do not have an unfettered right to “fire” class counsel. In the same vein, the class representatives cannot command class counsel to accept or reject a settlement proposal. To the contrary, class counsel must determine whether seeking the court’s approval of a settlement would be in the best interests of the class as a whole. Paragraph (1)(C) articulates the basic responsibility of the court to appoint class counsel who will provide the adequate representation called for by paragraph (1)(B). It identifies criteria that must be considered and invites the court to consider any other pertinent matters. Although couched in terms of the court’s duty, the listing also informs counsel seeking appointment about the topics that should be addressed in an application for appointment or in the motion for class certification. The court may direct potential class counsel to provide additional information about the topics mentioned in paragraph (1)(C) or about any other relevant topic. For example, the court may direct applicants to inform the court concerning any agreements about a prospective award of attorney fees or nontaxable costs, as such agreements may sometimes be significant in the selection of class counsel. The court might also direct that potential class counsel indicate how parallel litigation might be coordinated or consolidated with the action before the court. The court may also direct counsel to propose terms for a potential award of attorney fees and nontaxable costs. Attorney fee awards are an important feature of class action practice, and attention to this subject from the outset may often be a productive technique. Paragraph (2)(C) therefore authorizes the court to provide directions about attorney fees and costs when appointing class counsel. Because there will be numerous class actions in which this information is not likely to be useful, the court need not consider it in all class actions. Some information relevant to class counsel appointment may involve matters that include adversary preparation in a way that should be shielded from disclosure to other parties. An appropriate protective order may be necessary to preserve confidentiality. In evaluating prospective class counsel, the court should weigh all pertinent factors. No single factor should necessarily be determinative in a given case. For example, the resources counsel will commit to the case must be appropriate to its needs, but the court should be careful not to limit consideration to lawyers with the greatest resources. If, after review of all applicants, the court concludes that none would be satisfactory class counsel, it may deny class certification, reject all applications, recommend that an application be modified, invite new applications, or make any other appropriate order regarding selection and appointment of class counsel. Paragraph (2). This paragraph sets out the procedure that should be followed in appointing class counsel. Although it affords substantial flexibility, it provides the framework for appointment of class counsel in all class actions. For counsel who filed the action, the materials submitted in support of the motion for class certification may suffice to justify appointment so long as the information described in paragraph (g)(1)(C) is included. If there are other applicants, they ordinarily would file a formal application detailing their suitability for the position. In a plaintiff class action the court usually would appoint as class counsel only an attorney or attorneys who have sought appointment. Different considerations may apply in defendant class actions. The rule states that the court should appoint “class counsel.” In many instances, the applicant will be an individual attorney. In other cases, however, an entire firm, or perhaps numerous attorneys who are not otherwise affiliated but are collaborating on the action will apply. No rule of thumb exists to determine when such arrangements are appropriate; the court should be alert to the need for adequate staffing of the case, but also to the risk of overstaffing or an ungainly counsel structure. Paragraph (2)(A) authorizes the court to designate interim counsel during the pre-certification period if necessary to protect the interests of the putative class. Rule 23(c)(1)(B) directs that the order certifying the class include appointment of class counsel. Before class certification, however, it will usually be important for an attorney to take action to prepare for the certification decision. The amendment to Rule 23(c)(1) recognizes that some discovery is often necessary for that determination. It also may be important to make or respond to motions before certification. Settlement may be discussed before certification. Ordinarily, such work is handled by the lawyer who filed the action. In some cases, however, there may be rivalry or uncertainty that makes formal designation of interim counsel appropriate. Rule 23(g)(2)(A) authorizes the court to designate interim counsel to act on behalf of the putative class before the certification decision is made. Failure to make the formal designation does not prevent the attorney who filed the action from proceeding in it. Whether or not formally designated interim counsel, an attorney who acts on behalf of the class before certification must act in the best interests of the class as a whole. For example, an attorney who negotiates a pre-certification settlement must seek a settlement that is fair, reasonable, and adequate for the class. Rule 23(c)(1) provides that the court should decide whether to certify the class “at an early practicable time,” and directs that class counsel should be appointed in the order certifying the class. In some cases, it may be appropriate for the court to allow a reasonable period after commencement of the action for filing applications to serve as class counsel. The primary ground for deferring appointment would be that there is reason to anticipate competing applications to serve as class counsel. Examples might include instances in which more than one class action has been filed, or in which other attorneys have filed individual actions on behalf of putative class members. The purpose of facilitating competing applications in such a case is to afford the best possible representation for the class. Another possible reason for deferring appointment would be that the initial applicant was found inadequate, but it seems appropriate to permit additional applications rather than deny class certification. Paragraph (2)(B) states the basic standard the court should use in deciding whether to certify the class and appoint class counsel in the single applicant situation—that the applicant be able to provide the representation called for by paragraph (1)(B) in light of the factors identified in paragraph (1)(C). If there are multiple adequate applicants, paragraph (2)(B) directs the court to select the class counsel best able to represent the interests of the class. This decision should also be made using the factors outlined in paragraph (1)(C), but in the multiple applicant situation the court is to go beyond scrutinizing the adequacy of counsel and make a comparison of the strengths of the various applicants. As with the decision whether to appoint the sole applicant for the position, no single factor should be dispositive in selecting class counsel in cases in which there are multiple applicants. The fact that a given attorney filed the instant action, for example, might not weigh heavily in the decision if that lawyer had not done significant work identifying or investigating claims. Depending on the nature of the case, one important consideration might be the applicant’s existing attorney-client relationship with the proposed class representative. Paragraph (2)(C) builds on the appointment process by authorizing the court to include provisions regarding attorney fees in the order appointing class counsel. Courts may find it desirable to adopt guidelines for fees or nontaxable costs, or to direct class counsel to report to the court at regular intervals on the efforts undertaken in the action, to facilitate the court’s later determination of a reasonable attorney fee. Subdivision (h). Subdivision (h) is new. Fee awards are a powerful influence on the way attorneys initiate, develop, and conclude class actions. Class action attorney fee awards have heretofore been handled, along with all other attorney fee awards, under Rule 54(d)(2), but that rule is not addressed to the particular concerns of class actions. This subdivision is designed to work in tandem with new subdivision (g) on appointment of class counsel, which may afford an opportunity for the court to provide an early framework for an eventual fee award, or for monitoring the work of class counsel during the pendency of the action. Subdivision (h) applies to “an action certified as a class action.” This includes cases in which there is a simultaneous proposal for class certification and settlement even though technically the class may not be certified unless the court approves the settlement pursuant to review under Rule 23(e). When a settlement is proposed for Rule 23(e) approval, either after certification or with a request for certification, notice to class members about class counsel’s fee motion would ordinarily accompany the notice to the class about the settlement proposal itself. This subdivision does not undertake to create new grounds for an award of attorney fees or nontaxable costs. Instead, it applies when such awards are authorized by law or by agreement of the parties. Against that background, it provides a format for all awards of attorney fees and nontaxable costs in connection with a class action, not only the award to class counsel. In some situations, there may be a basis for making an award to other counsel whose work produced a beneficial result for the class, such as attorneys who acted for the class before certification but were not appointed class counsel, or attorneys who represented objectors to a proposed settlement under Rule 23(e) or to the fee motion of class counsel. Other situations in which fee awards are authorized by law or by agreement of the parties may exist. This subdivision authorizes an award of “reasonable” attorney fees and nontaxable costs. This is the customary term for measurement of fee awards in cases in which counsel may obtain an award of fees under the “common fund” theory that applies in many class actions, and is used in many fee-shifting statutes. Depending on the circumstances, courts have approached the determination of what is reasonable in different ways. In particular, there is some variation among courts about whether in “common fund” cases the court should use the lodestar or a percentage method of determining what fee is reasonable. The rule does not attempt to resolve the question whether the lodestar or percentage approach should be viewed as preferable. Active judicial involvement in measuring fee awards is singularly important to the proper operation of the class-action process. Continued reliance on caselaw development of fee-award measures does not diminish the court’s responsibility. In a class action, the district court must ensure that the amount and mode of payment of attorney fees are fair and proper whether the fees come from a common fund or are otherwise paid. Even in the absence of objections, the court bears this responsibility. Courts discharging this responsibility have looked to a variety of factors. One fundamental focus is the result actually achieved for class members, a basic consideration in any case in which fees are sought on the basis of a benefit achieved for class members. The Private Securities Litigation Reform Act of 1995 explicitly makes this factor a cap for a fee award in actions to which it applies. See 15 U.S.C. §§ 77z-1(a)(6); 78u-4(a)(6) (fee award should not exceed a “reasonable percentage of the amount of any damages and prejudgment interest actually paid to the class”). For a percentage approach to fee measurement, results achieved is the basic starting point. In many instances, the court may need to proceed with care in assessing the value conferred on class members. Settlement regimes that provide for future payments, for example, may not result in significant actual payments to class members. In this connection, the court may need to scrutinize the manner and operation of any applicable claims procedure. In some cases, it may be appropriate to defer some portion of the fee award until actual payouts to class members are known. Settlements involving nonmonetary provisions for class members also deserve careful scrutiny to ensure that these provisions have actual value to the class. On occasion the court’s Rule 23(e) review will provide a solid basis for this sort of evaluation, but in any event it is also important to assessing the fee award for the class. At the same time, it is important to recognize that in some class actions the monetary relief obtained is not the sole determinant of an appropriate attorney fees award. Cf. Blanchard v. Bergeron, 489 U.S. 87, 95 (1989) (cautioning in an individual case against an “undesirable emphasis” on “the importance of the recovery of damages in civil rights litigation” that might “shortchange efforts to seek effective injunctive or declaratory relief”). Any directions or orders made by the court in connection with appointing class counsel under Rule 23(g) should weigh heavily in making a fee award under this subdivision. Courts have also given weight to agreements among the parties regarding the fee motion, and to agreements between class counsel and others about the fees claimed by the motion. Rule 54(d)(2)(B) provides: “If directed by the court, the motion shall also disclose the terms of any agreement with respect to fees to be paid for the services for which claim is made.” The agreement by a settling party not to oppose a fee application up to a certain amount, for example, is worthy of consideration, but the court remains responsible to determine a reasonable fee. “Side agreements” regarding fees provide at least perspective pertinent to an appropriate fee award. In addition, courts may take account of the fees charged by class counsel or other attorneys for representing individual claimants or objectors in the case. In determining a fee for class counsel, the court’s objective is to ensure an overall fee that is fair for counsel and equitable within the class. In some circumstances individual fee agreements between class counsel and class members might have provisions inconsistent with those goals, and the court might determine that adjustments in the class fee award were necessary as a result. Finally, it is important to scrutinize separately the application for an award covering nontaxable costs. If costs were addressed in the order appointing class counsel, those directives should be a presumptive starting point in determining what is an appropriate award. Paragraph (1). Any claim for an award of attorney fees must be sought by motion under Rule 54(d)(2), which invokes the provisions for timing of appeal in Rule 58 and Appellate Rule 4. Owing to the distinctive features of class action fee motions, however, the provisions of this subdivision control disposition of fee motions in class actions, while Rule 54(d)(2) applies to matters not addressed in this subdivision. The court should direct when the fee motion must be filed. For motions by class counsel in cases subject to court review of a proposed settlement under Rule 23(e), it would be important to require the filing of at least the initial motion in time for inclusion of information about the motion in the notice to the class about the proposed settlement that is required by Rule 23(e). In cases litigated to judgment, the court might also order class counsel’s motion to be filed promptly so that notice to the class under this subdivision (h) can be given. Besides service of the motion on all parties, notice of class counsel’s motion for attorney fees must be “directed to the class in a reasonable manner.” Because members of the class have an interest in the arrangements for payment of class counsel whether that payment comes from the class fund or is made directly by another party, notice is required in all instances. In cases in which settlement approval is contemplated under Rule 23(e), notice of class counsel’s fee motion should be combined with notice of the proposed settlement, and the provision regarding notice to the class is parallel to the requirements for notice under Rule 23(e). In adjudicated class actions, the court may calibrate the notice to avoid undue expense. Paragraph (2). A class member and any party from whom payment is sought may object to the fee motion. Other parties—for example, nonsettling defendants—may not object because they lack a sufficient interest in the amount the court awards. The rule does not specify a time limit for making an objection. In setting the date objections are due, the court should provide sufficient time after the full fee motion is on file to enable potential objectors to examine the motion. The court may allow an objector discovery relevant to the objections. In determining whether to allow discovery, the court should weigh the need for the information against the cost and delay that would attend discovery. See Rule 26(b)(2). One factor in determining whether to authorize discovery is the completeness of the material submitted in support of the fee motion, which depends in part on the fee measurement standard applicable to the case. If the motion provides thorough information, the burden should be on the objector to justify discovery to obtain further information. Paragraph (3). Whether or not there are formal objections, the court must determine whether a fee award is justified and, if so, set a reasonable fee. The rule does not require a formal hearing in all cases. The form and extent of a hearing depend on the circumstances of the case. The rule does require findings and conclusions under Rule 52(a). Paragraph (4). By incorporating Rule 54(d)(2), this provision gives the court broad authority to obtain assistance in determining the appropriate amount to award. In deciding whether to direct submission of such questions to a special master or magistrate judge, the court should give appropriate consideration to the cost and delay that such a process might entail. Changes Made After Publication and Comment. Rule 23(c)(1)(B) is changed to incorporate the counsel-appointment provisions of Rule 23(g). The statement of the method and time for requesting exclusion from a (b)(3) class has been moved to the notice of certification provision in Rule 23(c)(2)(B). Rule 23(c)(1)(C) is changed by deleting all references to “conditional” certification. Rule 23(c)(2)(A) is changed by deleting the requirement that class members be notified of certification of a (b)(1) or (b)(2) class. The new version provides only that the court may direct appropriate notice to the class. Rule 23(c)(2)(B) is revised to require that the notice of class certification define the certified class in terms identical to the terms used in (c)(1)(B), and to incorporate the statement transferred from (c)(1)(B) on “when and how members may elect to be excluded.” Rule 23(e)(1) is revised to delete the requirement that the parties must win court approval for a precertification dismissal or settlement. Rule 23(e)(2) is revised to change the provision that the court may direct the parties to file a copy or summary of any agreement or understanding made in connection with a proposed settlement. The new provision directs the parties to a proposed settlement to identify any agreement made in connection with the settlement. Rule 23(e)(3) is proposed in a restyled form of the second version proposed for publication. Rule 23(e)(4)(B) is restyled. Rule 23(g)(1)(C) is a transposition of criteria for appointing class counsel that was published as Rule 23(g)(2)(B). The criteria are rearranged, and expanded to include consideration of experience in handling claims of the type asserted in the action and of counsel’s knowledge of the applicable law. Rule 23(g)(2)(A) is a new provision for designation of interim counsel to act on behalf of a putative class before a certification determination is made. Rule 23(g)(2)(B) is revised to point up the differences between appointment of class counsel when there is only one applicant and when there are competing applicants. When there is only one applicant the court must determine that the applicant is able to fairly and adequately represent class interests. When there is more than one applicant the court must appoint the applicant best able to represent class interests. Rule 23(h) is changed to require that notice of an attorney-fee motion by class counsel be “directed to class members,” rather than “given to all class members.” The language of Rule 23 has been amended as part of the general restyling of the Civil Rules to make them more easily understood and to make style and terminology consistent throughout the rules. These changes are intended to be stylistic only. Amended Rule 23(d)(2) carries forward the provisions of former Rule 23(d) that recognize two separate propositions. First, a Rule 23(d) order may be combined with a pretrial order under Rule 16. Second, the standard for amending the Rule 23(d) order continues to be the more open-ended standard for amending Rule 23(d) orders, not the more exacting standard for amending Rule 16 orders. As part of the general restyling, intensifiers that provide emphasis but add no meaning are consistently deleted. Amended Rule 23(f) omits as redundant the explicit reference to court of appeals discretion in deciding whether to permit an interlocutory appeal. The omission does not in any way limit the unfettered discretion established by the original rule. The time set in the former rule at 10 days has been revised to 14 days. See the Note to Rule 6.
