Levin v. Commerce Energy, Inc.
The Supreme Court ruled that companies complaining about unequal state taxes on their competitors must first go to state court, not federal court, even when they frame the lawsuit as a request to raise a rival's taxes rather than lower their own.
The decision applies a doctrine of judicial restraint called comity, which tells federal courts to stay out of disputes over how states run their own tax systems, and it resolves a split among federal appeals courts over how far that doctrine reaches after an earlier ruling had appeared to narrow it.
“The comity doctrine, we hold, requires that a claim of the kind here presented proceed originally in state court.”
The Court's core holding that this kind of tax-discrimination suit belongs in state court.
How it got here: A federal trial court dismissed the suit on comity grounds; the Sixth Circuit reversed, reading a footnote in an earlier Supreme Court case to narrow that doctrine; the Court granted review to resolve a circuit split.
The Case in Depth
What happened
Ohio consumers historically bought natural gas only from local utility companies, but independent marketers now compete with those utilities in big cities. Ohio gives the utilities tax breaks that independent marketers don't get. Several independent marketers and a customer sued Ohio's tax commissioner in federal court, arguing this unequal tax treatment violated the Commerce and Equal Protection Clauses, and asked the court to strike down the utilities' exemptions.
The question before the Court
Could natural gas sellers who competed with Ohio's local utilities sue in federal court to challenge tax breaks the utilities got but they didn't?
The Court's answer
No — the independent gas marketers could not bring their tax-discrimination claim in federal court, even though they framed it as a request to strip a tax break from their competitors rather than to lower their own taxes. The Court held that the comity doctrine, which asks federal courts to avoid interfering with how states manage their own tax systems, required the case to start in Ohio's state courts instead.
The Court reasoned that fixing unequal tax treatment can be done multiple ways, and state courts and legislatures are better positioned than federal courts to pick the right fix — especially since federal courts can't send a case back to state court once it's filed with them, and a separate federal law limits what remedies federal courts can order in tax cases. Because this was an ordinary commercial tax dispute with no fundamental right at stake, the Court found no reason for a federal court to get involved.

Why it matters
Businesses that believe a state's tax code favors their competitors can no longer sidestep state courts by relabeling their claim as an attack on someone else's tax break. Independent gas marketers in Ohio, and similarly situated businesses nationwide, must now pursue these discrimination claims in state courts, which have more flexibility to fix any constitutional problem.
What changes now
The case is sent back to the lower courts with instructions that the marketers' lawsuit cannot proceed in federal court and must instead be pursued, if at all, in Ohio's state courts. The ruling is a final decision on how comity applies to this type of tax-discrimination claim, though the Court left open whether the separate Tax Injunction Act would also have blocked the suit.
What this does not decide
The Court did not decide whether the Tax Injunction Act itself would have blocked this lawsuit, resting its decision solely on the comity doctrine. It also did not rule on the merits of whether Ohio's tax exemptions for local utilities are actually unconstitutional.
Concurrences and dissents
Concurrence — Justice Kennedy
Justice Kennedy joined the majority but flagged that he still finds the reasoning of the earlier Hibbs decision doubtful. He agreed to join only because the Court's opinion did not expand that earlier ruling any further.
Concurrence — Justice Thomas
Justice Thomas, joined by Justice Scalia, agreed the case belongs in state court but would have dismissed it for lack of jurisdiction under the Tax Injunction Act rather than resting on the discretionary comity doctrine. He argued the marketers were not outsiders to Ohio's tax scheme, so the statute's jurisdictional bar applied directly, and courts should resolve jurisdictional grounds before turning to prudential ones like comity.
Concurrence — Justice Alito
Justice Alito agreed that comity barred the suit but expressed doubt about the majority's effort to distinguish the Hibbs case, saying whether today's ruling undermines Hibbs is a question that can wait for another day.
How the Court got there
The legal reasoning, step by step
- The Court applied the comity doctrine, a rule of judicial restraint broader than the Tax Injunction Act, which tells federal courts to avoid deciding cases that would interfere with how states run their tax systems, out of respect for state self-governance.
- The Court explained that a prior decision's footnote about comity, from a case where outside taxpayers challenged a tax credit that funded religious schools, was written for a case with no stake in the plaintiffs' own tax bills and did not narrow comity's reach for cases like this one.
- Because economic and tax classifications get only lenient judicial review unless they touch a fundamental right, and because there are multiple ways a state could fix unequal tax treatment, the Court reasoned that only the state legislature or state courts are positioned to choose the right fix.
- The Court noted that federal courts cannot send a case they resolve back to a state court's docket, and that the Tax Injunction Act blocks federal courts from ordering remedies that would cut state tax revenue, so federal courts lack the tools to fashion an appropriate interim remedy here.
- Weighing that the marketers sought to boost their own competitive position through a commercial tax dispute with no heightened constitutional interest at stake, and that Ohio courts have more flexible remedial tools, the Court concluded the case belonged in state court under the comity doctrine.
