Exxon Corp. v. Eagerton
Headline: Alabama law banning producers from passing a severance tax increase to buyers is partly struck down for interstate gas sales but upheld for intrastate sales, and the royalty-owner tax exemption is upheld.
Holding: The Court held that Alabama’s ban on passing a severance tax increase to purchasers is preempted for interstate natural-gas sales but valid for intrastate sales, and the royalty-owner tax exemption is constitutional.
- Blocks state ban on passing tax increases for gas sold in interstate commerce, restoring federal pricing authority.
- Leaves states free to bar pass-throughs for gas sold only within the state.
- Affirms royalty-owner tax exemption, affecting who legally must pay increased severance taxes.
Summary
Background
Major oil and gas producers challenged Alabama’s 1979 law that raised a severance tax from 4% to 6%, exempted royalty owners from the increase, and barred producers from passing the added tax to purchasers. The pass-through ban took effect in September 1979 and was later repealed in 1980. Producers who paid the increase under protest sued for refunds. A trial court sided with the producers, the Alabama Supreme Court reversed, and the United States Supreme Court agreed to review the dispute.
Reasoning
The Court’s main question was whether federal law or the Constitution prevented Alabama from forbidding producers to pass the tax increase on to buyers or from exempting royalty owners. The Court held that federal law regulating wholesale natural gas prices occupies the field for interstate gas sales, so the state ban could not apply to gas sold in interstate commerce. But the ban could stand for gas sold only inside Alabama because Congress allowed states to set lower intrastate price limits. The Court also rejected challenges under the Contract Clause and Equal Protection Clause, finding the royalty-owner exemption did not nullify contracts and that the pass-through ban was a general consumer-protection rule with a rational basis.
Real world impact
The ruling means producers can be governed by federal pricing rules for interstate gas and cannot be forced by the state to absorb the tax there, while Alabama may bar pass-throughs for purely intrastate sales. The Court remanded to the Alabama courts to decide how much of the law survives and whether refunds are owed under state severability rules.
