Levin v. Commerce Energy, Inc.
The Supreme Court ruled that independent natural gas sellers challenging tax exemptions given to Ohio's gas utilities must bring their case in state court, not federal court, because federal courts should generally stay out of disputes over how states structure their own tax systems.
The decision narrows an earlier ruling, Hibbs v. Winn, that some lower courts had read as opening federal courts to a much wider range of state tax challenges, and it reinforces that federal courts should defer to states on tax administration except in unusual circumstances.
“Comity’s constraint has particular force when lower federal courts are asked to pass on the constitutionality of state taxation of commercial activity.”
Explains why federal courts should be especially cautious about state tax disputes involving businesses.
How it got here: A federal trial court dismissed the suit on comity grounds; the Sixth Circuit reversed and let it proceed; the tax commissioner asked the Supreme Court to resolve a circuit split.
The Case in Depth
What happened
Independent gas marketers and one of their customers sued Ohio's tax commissioner in federal court, arguing that Ohio's tax breaks for traditional gas utilities unfairly disadvantaged competing independent marketers. Rather than seeking a tax cut for themselves, they asked the federal court to strike down the utilities' exemptions, which would have leveled the playing field by raising the utilities' tax burden.
The question before the Court
Could independent natural gas marketers sue in federal court to challenge Ohio's tax breaks for their utility competitors, instead of suing in state court?
The Court's answer
No — the Court ruled that the independent gas marketers could not bring their tax-fairness challenge in federal court and instead had to sue in Ohio's own courts. The Court explained that a broader judge-made comity doctrine, not just the federal Tax Injunction Act, requires federal courts to step back from state tax disputes like this one out of respect for state control over fiscal matters.
The Court distinguished this situation from its earlier Hibbs v. Winn decision, which had allowed a federal Establishment Clause challenge to a different state tax credit to proceed. Unlike the Hibbs plaintiffs, who were financial outsiders with only one possible remedy, the marketers here were direct competitors complaining about their own relative tax burden, with several possible fixes better sorted out by Ohio's own courts and legislature.

Why it matters
Businesses that think a state's tax code favors their competitors will generally have to fight that battle in state court rather than federal court. The ruling also gives state tax agencies more certainty that ordinary tax-fairness disputes won't be pulled into federal litigation, preserving states' control over how they fix any tax problems that are found.
What changes now
The Sixth Circuit's judgment allowing the case to proceed in federal court is reversed, and the case is sent back for further proceedings consistent with the Supreme Court's ruling — meaning the marketers' suit will need to be pursued, if at all, in Ohio's state courts. This is a final merits ruling on where the case may be heard, though it does not resolve whether Ohio's tax exemptions are actually unconstitutional.
What this does not decide
The Court did not decide whether Ohio's tax exemptions for gas utilities actually violate the Constitution — only that any such challenge belongs in state court. It also did not decide whether the separate federal Tax Injunction Act independently would have blocked the suit, since comity alone was enough to require dismissal.
Concurrences and dissents
Concurrence — Justice Kennedy
Justice Kennedy joined the Court's opinion in full but flagged that he remains doubtful about the correctness of the Court's earlier decision in Hibbs v. Winn. He noted that nothing in today's ruling expands Hibbs, and on that understanding he was willing to join.
Concurrence — Justice Thomas
Justice Thomas, joined by Justice Scalia, agreed the case belongs in state court but would have dismissed for lack of jurisdiction under the Tax Injunction Act itself rather than on the discretionary comity ground. He argued that when a jurisdictional ground and a non-jurisdictional ground both support dismissal, courts should resolve the jurisdictional question first, and suspected the majority avoided doing so to preserve flexibility like that used in Hibbs.
Concurrence — Justice Alito
Justice Alito agreed that comity principles bar the suit but expressed doubt about the majority's efforts to distinguish Hibbs v. Winn, saying whether today's ruling actually undermines Hibbs's reasoning could be left for another case.
How the Court got there
The legal reasoning, step by step
- The Court explained that a judge-made comity doctrine, broader than the federal Tax Injunction Act, tells federal courts to avoid stepping into state tax disputes out of respect for states' control over their own fiscal affairs, even when a federal statute might not technically block the suit.
- The Court distinguished this case from Hibbs v. Winn, an earlier decision letting a federal Establishment Clause challenge to a state tax credit go forward, by noting that the Hibbs plaintiffs were financial outsiders who never objected to their own tax bills and had only one possible remedy: killing the credit outright.
- Here, by contrast, the marketers were direct competitors of the utilities receiving the tax breaks and were, in substance, complaining about their own comparative tax burden, with multiple possible fixes (cutting their own taxes, stripping the utilities' exemptions, or some other legislative solution) that only Ohio's legislature or courts could sensibly choose among.
- Because federal courts have no power to send a case they created back into the state court system for an interim fix, and because federal law bars them from ordering tax cuts that would shrink state revenue, the Court reasoned that federal courts are poorly positioned to manage this kind of remedy.
- Weighing that the marketers' claim did not involve a fundamental right, was really an attempt to gain a competitive edge, and that Ohio's own courts were better suited to figure out how to fix any constitutional problem, the Court concluded that comity required the case to proceed in state court instead.
