BOYLE, J.

We granted leave to appeal to examine the relationship between courts of general jurisdiction and the primary jurisdiction of the Michigan Public Service Commission (MPSC). Specifically, we address the question whether a circuit court may entertain a cause of action against a telephone company alleging negligence, despite the MPSC's primary jurisdiction over customer claims arising under MPSC tariffs. We also address the applicability of MPSC Tariff 7 to the plaintiff's case.

For the reasons that follow, we hold that, although a cause of action in tort against a telephone company or a claim that the company has violated the regulatory code or tariff may proceed in a court of general jurisdiction, the doctrine of primary jurisdiction requires dismissal of plaintiff's claim because it arises solely out of the contractual relationship between the telephone company and the plaintiff, its customer, and is limited by Tariff 7.

I. FACTS AND PROCEEDINGS

Plaintiff is a commercial and residential construction company located in Clinton Township. In May, 1991, plaintiff moved its place of business to a new address and requested that defendant Michigan Bell Telephone Company transfer its telephone service to the new address. Upon moving to the new address, plaintiff experienced various problems with its telephone service. Michigan Bell attempted to correct these problems by testing the line for trouble and by sending out repair personnel. Michigan Bell's records indicate that among the causes for these problems were unauthorized drop lines, underground cable damage, and problems with the plaintiff's own equipment.

In January, 1992, plaintiff filed a complaint in Macomb Circuit Court alleging negligence on the part of the defendant in installing and maintaining plaintiff's telephone service, proximately causing a great number of calls from customers and others not to be connected to plaintiff, and resulting in loss of business revenue in excess of $362,000. The complaint was later amended to add a res ipsa loquitur count and a wilful misrepresentation count based on a June, 1991, statement by the defendant that the problems had been corrected.

The defendant filed a motion for summary disposition pursuant to MCR 2.116(C)(4), arguing that the MPSC had "primary jurisdiction" over the plaintiff's claim, and that plaintiff had not exhausted its administrative remedies. Macomb Circuit Judge George C. Steeh granted the motion, concluding that the plaintiff's claims were within the jurisdiction of the MPSC, despite the allegations of negligence. The judge reasoned that there was no cause of action in tort where "the parties' relationship was purely contractual in nature since any alleged duties owed to plaintiff by defendant were governed by the MPSC tariffs."

The Court of Appeals affirmed in an unpublished per curiam opinion. Like the trial court, the Court of Appeals reasoned that the defendant's only duty to the plaintiff arose "as a result of a contractual agreement between defendant and a specific individual or entity." Unpublished opinion per curiam, issued February 27, 1995 (Docket No. 164509), slip op at 1. Thus, the Court concluded, plaintiff had no cognizable cause of action in tort and was required to assert its breach of contract claim before the MPSC. Id.

Plaintiff appealed to this Court, and we now affirm the Court of Appeals decision.

II. PRIMARY JURISDICTION A

Examination of the jurisdictional issue begins with this Court's decision in Valentine v. Michigan Bell Telephone Co, 388 Mich. 19, 25-26; 199 N.W.2d 182 (1972). In Valentine, we affirmed the dismissal of the plaintiff's claims in the context of a circuit court complaint seeking a declaration that the MPSC regulations limiting liability were "null and void as against public policy," and alleging "breach of contract, gross negligence, fraud and misrepresentation, malicious and fraudulent failure to provide reasonably adequate equipment and facilities and service, and willful and wanton negligence." Id. at 21-22.

Although the issue of primary jurisdiction was raised, we did not explicitly address the doctrine. Thereafter, panels of the Court of Appeals expressed uncertainty regarding the affect of the Valentine decision on the doctrine of primary jurisdiction in the context of suits against public utilities.

Primary jurisdiction "is a concept of judicial deference and discretion." LeDuc, Michigan Administrative Law, § 10:43, p 70. The doctrine exists as a "recognition of the need for orderly and sensible coordination of the work of agencies and of courts." White Lake Improvement Ass'n v. City of Whitehall, 22 Mich. App. 262, 282; 177 N.W.2d 473 (1970). In White Lake, the Court of Appeals correctly noted that "[t]he doctrine of primary jurisdiction does not preclude civil litigation; it merely suspends court action." Id. at 271. Thus, LeDuc notes, "[p]rimary jurisdiction is not a matter of whether there will be judicial involvement in resolving issues, but rather of when it will occur and where the process will start." Id. at § 10:44, p 73. A court of general jurisdiction considers the doctrine of primary jurisdiction "whenever there is concurrent original subject matter jurisdiction regarding a disputed issue in both a court and an administrative agency." Id. at § 10:43, p 70.

In Attorney General v. Diamond Mortgage Co, 414 Mich. 603, 613; 327 N.W.2d 805 (1982), we applied the United States Supreme Court's definition of the doctrine from United States v. Western P R Co, 352 U.S. 59; 77 S Ct 161; 1 L Ed 2d 126 (1956):

"`Primary jurisdiction' . . . applies where a claim is originally cognizable in the courts and comes into play whenever enforcement of the claim requires the resolution of issues which, under a regulatory scheme, have been placed within the special competence of an administrative body."

The Court observed, "No fixed formula exists for applying the doctrine of primary jurisdiction. In every case the question is whether the reasons for the existence of the doctrine are present and whether the purposes it serves will be aided by its application in the particular litigation." Id. at 64.

Professors Davis and Pierce identify three major purposes that usually govern the analysis when a court is deciding whether to defer to an administrative agency under this doctrine. First, a court should consider "the extent to which the agency's specialized expertise makes it a preferable forum for resolving the issue. . . ." Second, it should consider "the need for uniform resolution of the issue. . . ." Third, it should consider "the potential that judicial resolution of the issue will have an adverse impact on the agency's performance of its regulatory responsibilities." Davis Pierce, 2 Administrative Law (3d ed), § 14.1, p 272. Where applicable, courts of general jurisdiction weigh these considerations and defer to administrative agencies where the case is more appropriately decided before the administrative body.

In Diamond, for example, we rejected application of the doctrine because "[t]he rationales underlying the . . . doctrine [did] not support its application. . . ." Id. at 615. Speaking for the Court, Justice COLEMAN declined to apply the doctrine of primary jurisdiction because "the real estate brokerage business is not a heavily regulated industry of the type to which the doctrine has typically been held to apply." Id. at 614. Additionally, she explained that the courts, "without interfering with the responsibilities of the Department of Licensing and Regulation . . . can determine what the obligations of real estate brokers are under our consumer protection, usury, and corporation laws." Id. at 615. Finally, she observed that the nature of the factual questions in the case, whether defendant made misrepresentations in violation of the Michigan Consumer Protection Act, were not of a type to require agency expertise to evaluate. Id.

In Valentine, we held that claims by utility customers proceed in the circuit court where the "cause of action is based upon a claim that the utility has violated Public Service Commission promulgated tariffs or codes, or if the claim covers some action by the utility outside the regulations of the Public Service Commission. . . ." Id. at 25. While noting that where a plaintiff pleads a cause of action in tort, "the proper forum . . . is a court of general jurisdiction of this State," id. at 26, we observed with regard to contractual liability:

[T]he code or tariff is part of the contract between the parties and limits of liability therein contained are presumptively valid. Any claim based upon the contractual obligation of the parties is limited to validly promulgated provisions of the tariff or code within the authority of the Public Service Commission. Ordinarily, a party aggrieved by the provisions of a tariff or code should seek relief by an attack upon those provisions before the Public Service Commission. . . . [ Id. (emphasis added).]

In disposing of the case by affirming the lower courts' dismissals, the Court concluded:

No count sets forth acts or conduct of defendant that would constitute negligence, gross negligence, fraud, misrepresentation, or some other tort. As for any claim in contract, no violation of the code or tariff is pleaded. [ Id. at 30.]

Thus, where a plaintiff seeks relief against a telephone company in a court of general jurisdiction, under Valentine, the court may entertain (1) a cause of action in tort, or (2) a claim that the telephone company has violated the regulatory code or tariffs. Customer claims anticipated by the tariffs and regulations however, are governed by those tariffs, and relief from the presumptively valid limitations on liability therein must first be sought before the MPSC.

B

The Valentine decision is in harmony with the rationale underlying the doctrine of primary jurisdiction. The circuit court has not been ousted of its original jurisdiction under art 6, § 13 of the Michigan Constitution by the regulatory legislation. Under the telephone act of 1913, the MPSC possessed the "power and jurisdiction to hear and pass upon all matters pertaining to, necessary, or incident to the regulation of all public utilities, including . . . telephone. . . ." MCL 460.6(1); MSA 22.13(6)(1). In other words, the Legislature has broadly defined the power and jurisdiction of the MPSC over such matters, without explicitly providing that this power and jurisdiction is exclusive. Moreover, this is not an area in which the regulatory scheme preempts the field altogether so that all claims must be committed to the administrative body. See, e.g., San Diego Bldg Trades Council v. Garmon, 359 U.S. 236; 79 S Ct 773; 3 L Ed 2d 775 (1959) (denying California state court jurisdiction where union picketing giving rise to allegedly tortious acts was arguably encompassed by the National Labor Relations Act, 29 U.S.C. § 141 et seq.).

Causes of action in tort and those causes of action alleging that a telephone company has violated the tariffs or code are not cases in which the rationale underlying the doctrine of primary jurisdiction usually apply. The complexities of the regulatory scheme will generally not be implicated where the plaintiff's claim is for personal injury, property damage not covered by the tariffs, or other tortious activity, because the regulatory scheme is not designed to address these matters. Likewise, where the claim is that the defendant has somehow violated the tariffs or code, a court of general jurisdiction will usually be able to decide the legal issues involved in the case.

On the other hand, in Valentine we observed:

The jurisdiction of the [MPSC] is primarily prospective — a matter of promulgating regulations and setting rates. Its tariffs and regulations, if applicable, control as to the rights of the parties. The courts are primarily concerned with affording remedies for actions that have taken place. [ Id. at 30 (emphasis added).]

Where the claim asserted is essentially a matter already contemplated by the controlling tariffs, such as a claim for defective telephone equipment or service, and the only issue is the extent to which those tariffs will apply, deferral to the MPSC under the doctrine of primary jurisdiction is proper. The MPSC, charged with the authority to regulate and oversee telephone companies, possesses the degree of expertise with regard to the purpose and effect of the governing tariffs to decide whether the presumptively valid tariff provisions apply to particular facts that do not constitute tortious conduct or a violation of the code or tariff. Thus, the first consideration, the need for agency expertise, weighs in favor of deferral of such matters to the MPSC.

The second consideration, the need for uniformity in deciding matters incident to the regulatory scheme, also favors deferral to the MPSC. The MPSC has broad authority to regulate the rate structure to which a telephone company is subject. MCL 460.6(1); MSA 22.13(6)(1). In so doing, it balances the need for the telephone company to cover its expenses and absorb a reasonable return against the need to maintain affordable rates for the use of telephone service by the public. Uniform results in applying the tariffs to customer claims are essential to prevent the telephone company from being exposed to unanticipated liabilities that will hinder its ability to offer affordable telephone service.

Finally, applying the third consideration, if courts were to afford remedies separate from those provided in the tariffs, despite the fact that the tariffs contemplated claims of that nature when they were approved, such remedies could frustrate not only the uniform application of the regulatory scheme but also the agency's ability to perform its regulatory responsibilities. Thus, the considerations in favor of applying primary jurisdiction clearly favor deference to the MPSC. Primary jurisdiction over those claims covered by the tariffs allows the MPSC, through its regulatory expertise, to provide uniform and predictable results in the performance of its regulatory responsibilities. Allowing trial courts to resolve claims incident to the regulatory scheme, on the other hand, without the expertise of the MPSC, could lead to inconsistent application of the regulatory code or tariffs and competing standards for deciding when the regulatory scheme is operative. This is not what the Legislature intended when it granted the MPSC concurrent jurisdiction over matters incident to the regulatory scheme.

C

Where a customer asserts a cause of action arising purely out of the matters anticipated by the approved tariffs and code, i.e., the regulatory scheme, the doctrine of primary jurisdiction will require the court of general jurisdiction to defer to the MPSC. These matters, "pertaining to, necessary, or incident to the regulation of" the public utility, MCL 460.6(1); MSA 22.13(6)(1), are within the authority of the MPSC. Where, however, a plaintiff's cause of action against a utility company arises in tort, thus potentially requiring a remedy outside the regulatory scheme, or alleges that a telephone company somehow violated the regulatory code or the MPSC tariffs, such a cause of action may proceed in a court of general jurisdiction.

Plaintiff has not alleged any violation of the code or tariffs. Thus, the issue is whether plaintiff's claim is properly classified as an action in tort or as a claim "pertaining to, necessary, or incident to the regulation of" a public utility.

III. PLAINTIFF'S CLAIMS

Plaintiff claims in its brief that "by negligent tortious conduct, Defendant interrupted Plaintiff's business by negligently installing and/or maintaining telephone service to Plaintiff's business and by negligently misdirecting telephone calls intended for the Plaintiff to other telephone subscribers." Plaintiff's amended complaint set out allegations of ordinary negligence, res ipsa loquitur, and wilful misrepresentation. The alleged duties owed and violated by defendant were set forth as follows:

Michigan Bell . . . owed Plaintiff a duty to conduct its business in a reasonable manner; to provide the Plaintiff with adequate telephone service . . .; to employ competent trained personnel; to maintain, inspect and use equipment in an appropriate manner so as not to injure the Plaintiff in business; and to be honest and forthright in its dealings with Plaintiff.

We agree with the plaintiff that the defendant owed these duties; however, we conclude that they arose solely out of the contractual relationship between the parties and not from any independent legal obligations supporting a cause of action in tort. Thus, they are matters incident to the regulation of the telephone company within the primary jurisdiction of the MPSC.

A

Plaintiff relies on decisions of the Court of Appeals declining to apply the MPSC's primary jurisdiction with respect to alleged tortious activity on the part of the telephone company. Hunter v. General Telephone Co, 121 Mich. App. 411, 421; 328 N.W.2d 648 (1982); Thomas v. General Telephone Directory Co, 127 Mich. App. 788, 794-795; 339 N.W.2d 257 (1983). Those cases and others cited by both the plaintiff and the defendant turn on differing interpretations of what is required by Valentine in order to plead a cause of action against the telephone company in tort.

For example, in B W Rustproofing, Inc v. Michigan Bell Telephone Co, 88 Mich. App. 242; 276 N.W.2d 572 (1979), the Court reversed the circuit court's dismissal of the plaintiff's negligence claim where the plaintiff alleged that the defendant "failed to transfer calls to plaintiff's new number and failed to include that number in the [new] . . . directory." Id. at 243. The Court cited Valentine for the proposition that

"[a] claim in tort that sets forth facts which would constitute tortious conduct to the injury and damage of the claimant can also be filed in a court of general jurisdiction." [ Id. at 244 (emphasis added).]

Without further elaboration or analysis, the Court concluded, "The complaint sets forth allegations contending that defendant acted in a negligent manner. Since the complaint alleges tortious conduct on the part of defendant it was properly brought in circuit court." Id. at 245 (emphasis added). W E Westfall, Inc v. Michigan Bell Telephone Co, 129 Mich. App. 301; 341 N.W.2d 514 (1983), followed this approach, concluding that the circuit court had jurisdiction because the "plaintiff's complaint sets forth sufficient factual allegations to state an action in negligence." Id. at 304.

In Hunter, supra at 415, the Court of Appeals reversed an order of partial summary judgment, allowing the plaintiff to proceed in circuit court seeking "damages for the alleged negligent, reckless, wilful, wanton, malicious and intentional misconduct of defendants." These allegations arose from the alleged misdirection of callers attempting to reach the plaintiff's funeral home to the funeral home of the plaintiff's brother. Id. at 414. The trial court had granted partial summary judgment in part on the basis of the argument that the MPSC had exclusive jurisdiction over "`this essentially contractual dispute.'" Id. at 417. Despite its conviction that liability should be governed by MPSC Tariff 7, the Court of Appeals held that it was constrained by "binding precedent" from this Court to reverse and remand the plaintiff's theory of ordinary negligence for trial. Id. The Court read Valentine as appearing to affirm the notion that "once tortious conduct is properly alleged, a plaintiff may proceed in a court of general jurisdiction against a telephone company to recover full tort damages. . . ." Id. at 419.

The panel concluded that Valentine had essentially "emasculated" the regulatory scheme, id. at 421, but it was forced to reverse entry of partial summary judgment for the defendants. B W Rustproofing, Westfall, and Hunter apparently construed Valentine to resolve the jurisdictional question solely on the basis of a mere allegation of tortious conduct, without any serious inquiry into whether the facts alleged in the complaint actually supported the allegations of tortious conduct or violation of a legal duty independent of the contractual relationship. However, Valentine requires such inquiry in the very language quoted by the Court in B W Rustproofing.

Other panels of the Court of Appeals have rejected the approach that an allegation of negligence permits a plaintiff to proceed in a court of general jurisdiction. For example, in John Cannon Agency v. Michigan Bell Telephone Co, 128 Mich. App. 472, 476; 341 N.W.2d 115 (1981), the Court rejected the plaintiff's attempt to avoid MPSC limits on liability by alleging negligence in its complaint:

Plaintiff's claim, although phrased in tort, is clearly one which is based upon the contractual obligations of the parties. The only duty alleged in plaintiff's complaint is based upon defendant's promise to inform persons who dialed plaintiff's old telephone number of plaintiff's new telephone number. Plaintiff's argument must be rejected on the authority of Valentine, supra.

The Court of Appeals took this same approach in the instant case, stating:

In a contractual setting, a tort action must rest on a breach of duty distinct from contract. . . . Mere failure to perform an obligation under a contract cannot give rise to a negligence cause of action in tort. . . .

The instant defendant does not owe a general duty to provide and maintain telephone service to the public at large. To the contrary, defendant's "duty" to do so only arises as a result of a contractual agreement between defendant and a specific individual or entity. . . . [A]bsent the contract for telephone service . . . , defendant did not have a "duty" to provide and maintain the phone system in question. [Slip op at 1-2. See also Heitsch v. Hampton, 167 Mich. App. 629, 634; 423 N.W.2d 297 (1988) (refusing, absent extraordinary circumstances, to extend the defendant telephone company's duty beyond its contractual obligations).]

We clarify Valentine and hold that the jurisdictional question is not to be resolved by mere allegation, but rather by analysis of whether the facts pleaded give rise to a legal duty in tort independent of breach of contract.

B

Admitting that mere failure to perform or nonfeasance would not give rise to an action in tort, plaintiff asserts that this case sounds in tort because the defendant committed misfeasance in negligently failing to properly and fully perform its contract. The question whether an action in tort may arise out of a contractual promise has not been without difficulty. Hart v. Ludwig, 347 Mich. 559, 560; 79 N.W.2d 895 (1956). However, in Hart, the Court discussed the issue at length in determining whether the plaintiff could maintain an action in tort against a defendant who failed to adequately care for the plaintiff's orchard under the parties' oral contract. In refusing to allow the plaintiff's action to proceed in tort, the Court explained, quoting Tuttle v. Gilbert Mfg Co, 145 Mass. 169, 175; 13 N.E. 465 (1887):

"As a general rule, there must be some active negligence or misfeasance to support a tort. There must be some breach of duty distinct from breach of contract." [ Hart at 563.]

Acknowledging that the distinction between misfeasance and nonfeasance is often difficult to discern, the Court explained that the fundamental principle separating the causes of action is the concept of duty. The Court noted those cases where misfeasance on a contract was found to support an action in tort as follows:

[I]n each a situation of peril [was] created, with respect to which a tort action would lie without having recourse to the contract itself. Machinery [was] set in motion and life or property [ was] endangered. . . . In such cases . . . we have a "breach of duty distinct from . . . contract." Or, as Prosser puts it . . . "if a relation exists which would give rise to a legal duty without enforcing the contract promise itself, the tort action will lie, otherwise not." [ Id. at 565 (emphasis added).]

In other words, the threshold inquiry is whether the plaintiff alleges violation of a legal duty separate and distinct from the contractual obligation. The plaintiff's action in Hart failed to state a cause of action in tort because "[t]he only duty, other than that voluntarily assumed in the contract to which the defendant was subject, was his duty to perform his promise in a careful and skillful manner without risk of harm to others, the violation of which [was] not alleged." Id. at 565. The only other duty — to perform the promise — arose from the contract and could not support an action in tort. Id. at 565-566.

Prosser and Keeton discuss the distinction further:

Misfeasance or negligent affirmative conduct in the performance of a promise generally subjects an actor to tort liability as well as contract liability for physical harm to persons and tangible things. Generally speaking, there is a duty to exercise reasonable care in how one acts to avoid physical harm to persons and tangible things. Entering into a contract with another pursuant to which one party promises to do something does not alter the fact that there was a preexisting obligation or duty to avoid harm when one acts. [Torts, § 92, pp 656-657.]

This duty, however, does not extend to "intangible economic losses." Id. at 657. For this type of loss, "the manifested intent of the parties should ordinarily control the nature and extent of the obligations of the parties. . . ." Id. In addition to acknowledging this distinction at least as far back as Hart, the distinction has more recently been applied to sales contracts under the UCC under the rubric of the "economic loss doctrine." Neibarger v. Universal Cooperatives, 439 Mich. 512, 527; 486 N.W.2d 612 (1992). The concept has been approved in other contexts. See Corl v. Huron Castings, Inc, 450 Mich. 620, 626-628; 544 N.W.2d 278 (1996) (refusing to apply the collateral source rule for tort damages to an employment contract); Ferrett v. General Motors Corp, 438 Mich. 235, 243; 475 N.W.2d 243 (1991) (refusing to recognize a cause of action in tort for negligent evaluation of an employee).

In this case, as in Hart, the defendant agreed to provide the plaintiff with services under a contract. Like the defendant in Hart, Michigan Bell allegedly failed to fully perform according to the terms of its promise. While plaintiff's allegations arguably make out a claim for "negligent performance" of the contract, there is no allegation that this conduct by the defendant constitutes tortious activity in that it caused physical harm to persons or tangible property; and plaintiff does not allege violation of an independent legal duty distinct from the duties arising out of the contractual relationship. Like the plaintiff in Valentine, "regardless of the variety of names [plaintiff gives the] claim, [plaintiff is] basically complaining of inadequate service and equipment. . . ." Id. at 22. Thus, under the principles outlined above, there is no cognizable cause of action in tort.

C

Prosser and Keeton discuss "a few situations in which failure to perform a contract may amount to a tort." Torts, § 92, p 662. Such liability applies principally to common carriers and public utilities under "the old tort duty to serve all comers which arose as to common callings before the idea of contract had developed." Id. Although telephone companies and other utilities may appear to fall under this old duty, the comprehensive regulatory scheme set up by the Legislature and under which the MPSC was created supersedes the applicability of this duty in Michigan. Prosser Keeton state:

Most public utilities are now rather intensely regulated. . . . [T]he duty and responsibilities of the regulated industries should be and are largely determined . . . by the regulatory agencies. In dealing with the civil liability of a public utility . . ., primary attention has been given to the nature of the loss. . . . Intangible consequential damages for interruptions of service and defective performance will normally be allocated to the customer under tariff provisions approved by regulatory agencies. Substantial losses of this kind are normally incurred by industrial and commercial customers who can insure against losses. . . . In the light of this regulatory process, the civil liability is neither tortious nor contractual but is rather sui generis. [ Id. at 663.]

This is precisely how the regulatory scheme in Michigan was designed to work. The Legislature provided for the regulatory and jurisdictional authority of the MPSC. In the telephone act of 1913, MCL 460.6(1); MSA 22.13(6)(1) provided:

The public service commission is vested with complete power and jurisdiction to regulate all public utilities in the state. . . . The public service commission is vested with the power and jurisdiction to regulate all . . . services, rules, conditions of service, and all other matters pertaining to the formation, operation, or direction of such public utilities. The public service commission is further granted the power and jurisdiction to hear and pass upon all matters pertaining to, necessary, or incident to the regulation of all public utilities, including . . . telephone. . . .

MPSC Tariff 7 states the following with regard to liability for damages:

C. Liability of the Company

1. In the event of an interruption to the service which is not due to the negligence or willful act of the customer, upon notice and application by the customer an allowance will be made for the time interruption continues.

2. The liability of the Company for damages arising out of mistakes, omissions, interruptions, delays, errors or defects in transmission, or failures or defects in facilities furnished by the Company, occurring in the course of furnishing service or other facilities and not caused by the negligence of the customer, or of the Company in failing to maintain proper standards of maintenance and operation and to exercise reasonable supervision shall in no event exceed an amount equivalent to the proportionate charge to the customer for the period of service during which such mistake, omission, interruption, delay or error or defect in transmission, or failure or defect in facilities occurs.

This provision provides that where a customer's telephone service is defective in a manner anticipated in the tariff, and it is not the customer's fault, recovery of intangible economic losses, whatever their cause, is limited to the amount the customer paid for the service during the time it was defectively provided. Such defects, by virtue of the fact the tariff anticipated them, are matters "incident to the regulation of" the telephone company. Tariff 7's limitation on liability for nonperformance or incomplete performance by a telephone company is presumptively valid, and, as part of the contract between the parties, is the manifested intention of the parties to the agreement. Valentine at 25-26. If a customer is aggrieved by this contractual provision, under the doctrine of primary jurisdiction, its first remedy is before the governing administrative body — the MPSC — not a court of general jurisdiction.

D

As noted above, the problems plaintiff reported to defendant were no dial tone, false busy signals, crossed lines, inability to receive or place calls without a calling card, static, misdirection to another number, no ringing, and low volume. Assuming, as we do for present purposes, that these problems were solely the fault of the defendant, they still fall under the broad language of the tariff as "mistakes, omissions, interruptions, delays, errors or defects in transmission, or failures or defects in facilities furnished by the Company, occurring in the course of furnishing service or other facilities and not caused by the negligence of the customer. . . ." Thus, because these types of problems are anticipated by the tariffs, and are matters incident to the regulation of the utility, the plaintiff's claim falls within the primary jurisdiction of the MPSC and is limited by the tariff.

IV. CONCLUSION

The plaintiff's cause of action was properly dismissed in favor of the primary jurisdiction of the MPSC where the only duty allegedly breached was the contractual duty the defendant had to the plaintiff under the terms of the customer service relationship. The plaintiff did not allege any violation of the regulatory code or tariffs, nor did it allege acts sufficient to constitute tortious conduct. The presumptively valid and comprehensive regulatory scheme anticipated this type of liability and accounted for it adequately as a matter pertaining to the regulation of the public utility. The decision of the Court of Appeals is affirmed.
