Wis. Stat. § 802.05
The above case annotations refer to s. 802.05 as it existed prior to its repeal and recreation by SCO 03-06.
This section does not allow a "good faith" defense, but imposes an affirmative duty of reasonable inquiry before filing. A party prevailing on appeal in defense of an award under this section is entitled to a further award without showing that the appeal itself is frivolous under s. 809.25(3). Riley v. Isaacson, 156 Wis. 2d 249, 456 N.W.2d 619 (Ct. App. 1990). An unsigned summons served with a signed complaint is a technical defect, which in the absence of prejudice does not deny the trial court personal jurisdiction. This section places a personal obligation on the attorney to assure that there are grounds for the contents of the pleading, which is satisfied by the signing of the complaint. Gaddis v. LaCrosse Products, Inc., 198 Wis. 2d 396, 542 N.W.2d 454 (1996), 94-2121. The return of a writ of certiorari is an "other document" under this section. Attorney failure to verify its correctness before signing the return was ground for sanctions. State ex rel. Campbell v. Town of Delavan, 210 Wis. 2d 239, 565 N.W.2d 209 (Ct. App. 1997), 96-1291. In determining the reasonableness of an attorney's inquiry, a court must consider: 1) the amount of time the attorney had to investigate the claims; 2) the extent to which the attorney had to rely on the client for the underlying facts; 3) whether the case was accepted from another attorney; 4) the complexity of the facts; and 5) whether discovery would benefit the factual record. At minimum some affirmative investigation is required. Belich v. Szymaszek, 224 Wis. 2d 419, 592 N.W.2d 254 (Ct. App. 1999), 97-3447. A plaintiff need not as a matter of course exhaust outside sources of information before embarking on formal discovery. However, a plaintiff may not rely on formal discovery to establish the factual basis of its cause of action, thereby escaping the mandates of ss. 802.05 and [former] 814.025, when the required factual basis could be established without discovery. Jandrt v. Jerome Foods, Inc., 227 Wis. 2d 531, 597 N.W.2d 744 (1999), 98-0885. The standard for determining whether a claim may be dismissed under sub. (3) (b) 4. is the same standard applied in a normal civil case for failure to state a claim upon which relief can be granted. A case should be dismissed only if it is quite clear that under no circumstances can a plaintiff recover. State ex rel. Adell v. Smith, 2001 WI App 168, 247 Wis. 2d 260, 633 N.W.2d 231, 00-0070. A stamped reproduction of a signature does not satisfy s. 801.09(3), and correcting the signature a year after receiving notice of the defect is not timely under sub. (1) (a). The error must be promptly corrected, or else the certification statute and the protection it was intended to afford is rendered meaningless. Novak v. Phillips, 2001 WI App 156, 246 Wis. 2d 673, 631 N.W.2d 635, 00-2416. See also Schaefer v. Riegelman, 2002 WI 18, 250 Wis. 2d 494, 639 N.W.2d N.W.2d 715, 00-2157 reversing the holding of that the error was technical and not fundamental. A summons and complaint signed by an attorney not licensed in the state contained a fundamental defect that deprived the circuit court of jurisdiction even though the signature was made on behalf and at the direction of a licensed attorney. Schaefer v. Riegelman, 2002 WI 18, 250 Wis. 2d 494, 639 N.W.2d N.W.2d 715, 00-2157. The failure to sign a notice of appeal can be corrected and does not compel immediate dismissal. State v. Seay, 2002 WI App 37, 250 Wis. 2d 761, 641 N.W.2d 437, 00-3490. The handwritten signature on a summons and complaint of an attorney of record who had been suspended from the practice of law was a fundamental defect. The defect was not cured when an amended complaint was filed with new counsel's signature but when no amended or corrected summons was ever filed. Town of Dunkirk v. City of Stoughton, 2002 WI App 280, 258 Wis. 2d 805, 654 N.W.2d 488, 02-0166. The circuit court's sua sponte dismissal of a petition for a writ of certiorari did not violate the right to due process or equal protection. Due process was satisfied because of constructive notice under sub. (3) (b), together with post-dismissal procedures available to the prisoner. Equal protection was satisfied because the initial pleading review procedure satisfied the rational basis test. Schatz v. McCaughtry, 2003 WI 80, 263 Wis. 2d 83, 664 N.W.2d 596, 01-0793. When petitioners and their counsel knew events related in their petition had not occurred when the petition was signed and sworn to and had not occurred when they filed the petition with the court, the trial court could reasonably decide that constituted a violation of the obligation to make a reasonable inquiry to insure that their petition was well-grounded in fact. The court properly rejected their rationale that the event did come about as expected. Robinson v. Town of Bristol, 2003 WI App 97, 264 Wis. 2d 318, 667 N.W.2d 14, 02-1247. Sub. (1) expressly authorizes sanctions against a represented client who has not signed a pleading and does not require the signing attorney to personally have the improper purpose. Lack of evidence that a signing attorney was or should have been aware the client was using the complaint for an improper purpose does not result in the conclusion that the complaint was not used for an improper purpose, but is relevant to whom to sanction. Wisconsin Chiropractic Association v. Chiropractic Examining Board, 2004 WI App 30, 269 Wis. 2d 837, 676 N.W.2d 580, 03-0933. In order to confer jurisdiction on the court of appeals, a notice of appeal filed by counsel must contain the handwritten signature of an attorney authorized to practice law in Wisconsin. Counsel cannot delegate the duty to affix a signature on a notice of appeal to a person not authorized to practice law in Wisconsin. When a notice of appeal is not signed by an attorney when an attorney is required, the notice of appeal is fundamentally defective and cannot confer jurisdiction. Brown v. MR Group, LLC, 2004 WI App 121, 274 Wis. 2d 804, 683 N.W.2d 804, 03-2309. To avoid permitting prisoners to easily avoid the judicial screening requirement that is central to the purpose s. 802.05(3), 2003 stats., prisoners may not amend their initial pleadings as a matter of course under s. 802.09(1). A prisoner's amendment of an initial pleading is subject to the judicial screening requirement of s. 802.05(3), 2003 stats., and a court must review the proposed amended pleading under that subsection before granting the prisoner leave to amend. Lindell v. Litscher, 2005 WI App 39, 280 Wis. 2d 159, 694 N.W.2d 396, 03-2477. If a pleading that does not conform to the subscription requirement of sub. (1) (a) is characterized as containing a fundamental defect that normally deprives the court of jurisdiction, that pleading is curable. Rabideau v. Stiller, 2006 WI App 155, 295 Wis. 2d 417, 720 N.W.2d 108, 05-2868. The Effect of Jandrt on Satellite Litigation. Geske & Gleisner. Wis. Law. May 2000. Frivolous Sanction Law in Wisconsin. Geske & Gleisner. Wis. Law. Feb. 2006. This section is a procedural rule and procedural rules generally have retroactive application. However, this section, as affected by Supreme Court Order 03-06, is not to be applied retroactively when the new rule diminishes a contract, disturbs vested rights, or imposes an unreasonable burden on the party charged with complying with the new rule's requirements. Trinity Petroleum, Inc. v. Scott Oil Company, Inc., 2007 WI 88, 302 Wis. 2d 299, 735 N.W.2d 1, 05-2837. Sub. (3) (a) 1. requires the party seeking sanctions to first serve the motion on the potentially sanctionable party, who then has 21 days to withdraw or appropriately correct the claimed violation. The movant cannot file a motion for sanctions unless that time period has expired without a withdrawal or correction. A postjudgment sanctions motion does not comply with sub. (3) (a) 1. It would wrench both the language and the purpose of the rule to permit an informal warning to substitute for service of the motion. Ten Mile Investments, LLC v. Sherman, 2007 WI App 253, 306 Wis. 2d 799, 743 N.W.2d 442, 06-0353. Under sub. (1), every motion filed in court must be signed by an attorney or it shall be stricken. Sub. (1) required the circuit court to strike from the record an affidavit and proposed order submitted by a child support agency that was not executed by an attorney. Teasdale v. Marinette County Child Support Agency, 2009 WI App 152, 321 Wis. 2d 647, 775 N.W.2d 123, 08-2827. Chapter 767 does not prohibit civil sanctions for frivolous proceedings under this section. Therefore, a motion for sanctions under subs. (2) and (3) in a divorce action under ch. 767 is governed by civil procedure because ch. 767 does not preclude such motions. Wenzel v. Wenzel, 2017 WI App 75, 378 Wis. 2d 670, 904 N.W.2d 384, 16-1771.
