Commerce Clause Challenge to State Truck Hitch Statute

Introduction and Facts

Tanya Trucker is a trucking company owner who resides in and operates her business in the state of Denial. Her trucking business also operates in the state of Confusion and in other states. The state of Confusion enacted a statute requiring all trucks and towing trailers that use its highways to install a B-type truck hitch, which is manufactured by only one manufacturer located in Confusion. As a result, truckers must either avoid Confusion entirely or have the hitch installed at their own expense. The federal government has not attempted to regulate truck hitches on the nation's highways. Tanya Trucker intends to file suit against Confusion to overturn the statute.

Two central legal questions arise from these facts: (1) Is the Confusion state statute requiring the B-type truck hitch constitutional? (2) What court would have jurisdiction over this dispute?

Jurisdiction: Which Court May Hear the Case

Before determining whether the statute is constitutional, it is necessary to identify which court would have original jurisdiction over the dispute. The candidates are the federal district court for the state of Denial, the federal district court for the state of Confusion, or a state court. Resolving this question requires examining whether federal diversity jurisdiction applies or whether a state court would retain jurisdiction.

Because Tanya Trucker is located in a state outside of Confusion, she and the opposing party are considered diverse. Under 28 U.S.C. § 1331, federal district courts have original jurisdiction over all actions arising under the Constitution, laws, or treaties of the United States. Under 28 U.S.C. § 1332(a)(b), federal courts have original jurisdiction over lawsuits between citizens of different states when the amount in controversy is at least $75,000.

A complication arises, however, because Tanya Trucker's lawsuit is directed not against a private citizen of Confusion but against the state itself. Under U.S. Const. amend. XI, citizens are prohibited from suing states in federal court without an express waiver by the state. However, the stripping doctrine — rooted in Ex parte Young — permits such suits when they are filed against a named state official rather than the state itself. In this scenario, Tanya Trucker would presumably file suit against the head of whatever agency is responsible for enforcing interstate trucking regulations in Confusion. That named official would be considered a citizen of Confusion, which would give rise to diversity jurisdiction provided the other requirements of 28 U.S.C. § 1332(a)(b) are also satisfied.

Underlying the jurisdictional question is whether this case arises under federal law or is merely a matter of state law. In other words, does Confusion have the right to require those trailer hitches, or does Tanya Trucker have a colorable argument that the statute infringes upon a federal legislative domain? To answer this, one must examine U.S. Const. art. I, § 8(3), commonly known as the Commerce Clause, which grants Congress the power "to regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes." States are therefore specifically prohibited from enacting legislation that impedes interstate commerce. Generally, this provision has been applied where a state law favors in-state interests over out-of-state interests, thereby discouraging participation in interstate commerce.

This issue has also been addressed in case law. In Southern Pacific Co. v. Arizona, 61 Ariz. 66, 145 P.2d 530 (1945), the Court considered whether a law that treated in-state and out-of-state parties the same could nonetheless violate the Commerce Clause. The facts were strikingly similar to the present hypothetical: Arizona had enacted a law prohibiting freight trains carrying more than 70 freight cars from crossing the state. The practical effect was that railroads were required to disassemble their large trains before entering Arizona, resulting in added expenses and delays. The Southern Pacific Court held the law unconstitutional because it interfered with travel, and the right to unfettered travel is at the heart of the Commerce Clause.

Commerce Clause Analysis

It is somewhat difficult to determine with certainty which court would have jurisdiction, because the factual scenario does not provide sufficient detail to answer the question definitively. The issue clearly involves a federal constitutional question, which is one prerequisite for triggering federal jurisdiction. Because Tanya Trucker is in Denial and the challenged law is a Confusion state statute, either the federal district court for Denial or the federal district court for Confusion could likely exercise diversity jurisdiction — provided the amount in controversy reaches $75,000 as required by 28 U.S.C. § 1332(a)(b).

Whether Tanya Trucker's damages would reach that threshold cannot be determined from the facts given. It seems unlikely that the cost of replacing hitches on a truck fleet would reach $75,000 unless the fleet were extraordinarily large. However, even if her damages are insufficient to trigger diversity jurisdiction, she can bring suit in a Confusion state trial court, which unquestionably has jurisdiction over the matter and imposes no amount-in-controversy requirement.

Wherever she brings suit, it appears clear that Tanya Trucker should prevail. Under the Commerce Clause, Congress holds the exclusive power to regulate commerce among the states. Even rationally based statutes that substantially impact interstate commerce are impermissible when they create a burden on that commerce. The Confusion statute requires truckers to either change hitches or avoid the state entirely, which would obviously affect the import and export of goods into and out of Confusion, as well as the delivery of goods to other destinations. The statute clearly burdens interstate commerce and cannot withstand constitutional scrutiny.
