The trial court granted defendants’ motion for summary disposition, MCR 2.116(C)(4) and (7), in its order of January 19, 1990. Plaintiff appeals as of right from that order. We reverse the trial court’s decision and remand this matter to the trial court for additional proceedings.
Plaintiff is a common and contract motor carrier with its principal place of business in Sterling Heights, Michigan. Plaintiff operates primarily in interstate commerce, with only 4.8 percent of its 1988 revenues being generated from intrastate operations in Michigan. It is plaintiff’s custom and practice to enter into contracts with independent contractors to provide leased equipment and driving services.
*36 Section 10a(6) of the Motor Carrier Act, MCL 479.10a(6); MSA 22.575(1)(6), requires intrastate motor carriers to operate only with direct employees, rather than with independent contractors. The Public Service Commission sent written notices informing plaintiff that it was not permitted to utilize independent contractors to operate leased equipment, and advising plaintiff to bring its intrastate leases into compliance with the statute. The psc refused to allow plaintiff to add equipment to its intrastate operations and refused to grant the decals necessary for intrastate operation until plaintiff complied with § 10a(6).
Plaintiff filed a complaint in the Macomb Circuit Court, requesting a preliminary injunction, a permanent injunction, a declaratory judgment, and a writ of mandamus against defendants. Plaintiff contended that the psc’s application of § 10a(6), which denied plaintiff, a carrier primarily engaged in interstate commerce, the right to intrastate decals and the use of additional equipment, was in violation of the Commerce Clause of the United States Constitution. US Const, Art I, § 8. Plaintiff argued that federal regulations allow interstate carriers to operate leased equipment with independent contractors, and claimed that its intrastate business was only incidental to its general business of interstate commerce. Plaintiff contends that § 10a(6) violates the Commerce Clause because it subjects plaintiff to inconsistent regulations and unduly burdens interstate commerce. Plaintiff requested a declaratory ruling from the circuit court that § 10a(6) was unconstitutional. Among the other requested relief, plaintiff asked that the psc be forced to apply this section in a manner consistent with the federal constitution.
Defendants moved for summary disposition of the complaint. The trial court found that it did not *37 have subject-matter jurisdiction over plaintiffs challenges to the actions by the psc and that plaintiff had failed to exhaust reasonable and available administrative remedies. The trial court granted summary disposition, and plaintiffs complaint was dismissed with prejudice. We believe both parts of the trial court’s ruling were erroneous.
Whether a court has subject-matter jurisdiction is a question of law.
Dep’t of Natural Resources v Holloway Construction Co,
The psc’s jurisdiction is limited to regulating motor carriers involved in intrastate commerce, MCL 460.6(1); MSA 22.13(6X1). While the psc has jurisdiction over the enforcement of the Motor Carrier Act, it has generally been held that an agency that exercises quasi-judicial authority does not possess the power to determine the constitutionality of statutes.
Wikman, supra,
pp 646-647;
Eyde v Lansing Twp,
In the case at bar, plaintiff’s entitlement to the relief requested was dependent upon a ruling that § 10a(6), as applied to interstate motor carriers, was unconstitutional under the Commerce Clause. Plaintiff was directly challenging the constitutionality of the statute and not merely couching the complaint in constitutional terms. We find that the trial court erred in determining that it lacked subject-matter jurisdiction. See also
Plymouth Twp v Wayne Co Bd of Comm’rs,
While it was possible for plaintiff to have first pursued any remedies it may have had before the psc, both judicial economy and the interests of justice supported plaintiff’s actions in filing a complaint in the circuit court for declaratory relief. Plaintiff claimed that the psc lacked statutory authority to regulate it because its primary business as an interstate carrier fell outside the parameters of the powers granted by the Legislature to the psc over intrastate carriers. Plaintiff’s pursuit of its administrative remedies would have been futile; therefore, the failure to do so is excusable.
Generou v Kalamazoo Regional Psychiatric Hosp,
We also believe that the doctrine of primary jurisdiction does not apply because the agency’s statutory authority and the constitutionality of § 10a(6) were issues that did not require the agency’s special expertise or fact-finding skills.
Attorney General v Diamond Mortgage Co,
We are satisfied that the remainder of defendants’ arguments do not support the trial court’s ruling. While appeals from certain decisions of the psc may be pursued directly in this Court, rather than in the circuit court, MCL 462.26(1); MSA 22.45(1), such procedure is limited to appeals from "any order of the commission fixing any rate or rates, fares, charges, classifications, joint rate or rates, or any order fixing any regulations, practices, or services.” Section 26(1) merely addresses the appeal procedure that results from orders issued by the psc, and it is not applicable where the jurisdiction of the psc is not initially invoked. Therefore, it is distinguishable from the case at bar. 1
Defendants also argue that MCL 24.263; MSA
*40
3.560(163) and MCL 24.264; MSA 3.560(164) mandate that declaratory actions be filed with the administrative tribunal in the first instance, rather than with the circuit court. These statutes allow the psc to issue declaratory rulings regarding the applicability of a rule or statute administered by the agency to an actual set of circumstances. When rendering a declaratory judgment, an administrative agency is permitted to determine the validity of rules promulgated by the agency, but not statutes enacted by the Legislature. See MCL 24.207; MSA 3.560(107); MCL 24.264; MSA 3.560(164);
Bentley v Dep’t of Corrections,
Defendants have also raised other issues that they contend support the trial court’s decision to grant summary disposition. Because these issues were not addressed by the trial court, and go beyond its subject-matter jurisdiction, we will not address them for the first time on appeal.
Joe Dwyer, Inc v Jaguar Cars, Inc,
Reversed and remanded. We do not retain jurisdiction.
Notes
We likewise do not believe that MCL 462.26(4), (5); MSA 22.45(4), (5) should be read to prohibit the circuit court from issuing any injunctions in this case. MCL 462.26(4); MSA 22.45(4) bars courts other than this Court from issuing injunctions. However, this subsection must be read in the context of the entire statute, and it is clear that MCL 462.26(4), (5); MSA 22.45(4), (5) are only meant to apply .to injunctions against the psc that are issued pending an appeal of an order of the psc.
