Ingels v. Morf
The Supreme Court struck down California's 'Caravan' Act permit fee as applied to an interstate car dealer, ruling that the $15-per-car fee was far higher than what the state actually needed to police and administer the caravan traffic.
Because the fee could not be justified as a reasonable charge for highway use or policing costs, it amounted to an unconstitutional burden on interstate commerce, even though states can charge reasonable fees tied to real costs.
“To justify the exaction by a state of a money payment burdening interstate commerce, it must affirmatively appear that it is demanded as reimbursement for the expense of providing facilities, or of enforcing regulations of the commerce which are within its constitutional power.”
The Court's core test for when a state fee on interstate commerce is constitutionally valid.
How it got here: A three-judge federal district court in Southern California ruled for the car dealer and blocked the law; California officials appealed directly to the Supreme Court.
The Case in Depth
What happened
A Los Angeles car dealer bought used cars in other states and drove them, sometimes in groups called caravans, into California to sell. California's Caravan Act required a $15 permit for each car brought in this way, with the money going to the state's general fund, ostensibly to cover the cost of administering the law and policing caravan traffic on the highways.
The question before the Court
Could California charge a special $15-per-car permit fee on out-of-state car dealers driving used cars into the state to sell, when the money went into the general treasury rather than actual highway or policing costs?
Why it matters
Businesses that move goods or vehicles across state lines are protected from state fees that go well beyond what it actually costs the state to police or regulate that traffic. States must show a real link between a fee and its stated purpose, or the fee can be struck down as an illegal tax on interstate trade.
What changes now
The decision affirms the lower court's ruling blocking enforcement of the permit-fee provisions against the interstate car dealer. The Court did not need to decide whether a separate provision requiring spacing between vehicles in a caravan could be enforced on its own, apart from the invalid licensing fee, leaving that question open for future cases.
What this does not decide
The Court did not decide whether California's rule requiring spacing between vehicles in a caravan could be enforced by itself, separate from the licensing fee, in a law that did not discriminate against interstate commerce. It also did not resolve whether comparable in-state traffic truly went untaxed.

How the Court got there
The legal reasoning, step by step
- The Court explained that a state fee burdening interstate commerce is only valid if it is shown to reimburse the state for real costs of providing highway facilities or enforcing legitimate regulations, rather than acting as a disguised tax on interstate trade.
- This justification can come either from the statute's own terms or from how the collected money is actually spent; here, the statute itself declared the fees were meant to cover the cost of administering the Act and policing caravan traffic, but the money went into the general treasury rather than any highway fund.
- Because the statute specified this administrative and policing purpose, the burden fell on the car dealer to prove that the $15 fee charged for each car was excessive compared to those actual costs.
- The trial court found that the total realistic cost of policing and administering the caravan traffic was far below what the fees would generate — roughly $24,000 to $29,000 a year in costs against about $225,000 in fees collected from 15,000 cars.
- Applying this comparison, the Court concluded that the fee bore no reasonable relation to the actual cost of regulating the caravan traffic, so it functioned as an improper charge rather than a legitimate reimbursement for state expenses.
