Chevron USA Incorporated, et al., Petitioners v. Plaquemines Parish, Louisiana, et al.

Louisiana parishes sued oil companies in state court, claiming their operations damaged coastal lands. The companies want to move these cases to federal court, arguing they were acting as 'federal officers' because they produced oil to support the U.S. military during World War II.

The outcome will determine if local governments can use state laws to sue companies for environmental harm or if those cases must go to federal court. This could make it harder or easier for communities to win money for restoring damaged wetlands and coastlines.

This case tests the 'federal officer removal statute,' a law that lets people working for the government move state lawsuits to federal court. The Court must decide if simply following a government contract to provide fuel is enough to count as acting under federal authority.

During oral arguments, the discussion focused on whether the wartime contracts gave the government enough specific control over oil production. The oil companies argued their work was essential for the war effort, while the parishes argued the contracts did not tell the companies exactly how to drill or manage the land.

The Supreme Court is deciding if oil companies can use their history as wartime suppliers to avoid being sued in Louisiana state courts for environmental damage.

The Court has finished hearing arguments and will now meet privately to vote on the outcome. A final written decision is expected by the end of the term in June 2026.

The parishes want to sue in state court for coastal damage. The companies argue that their wartime fuel production for the government means the cases belong in federal court.

If the oil companies win, many other companies with government contracts might try to move local lawsuits to federal court. This could make it more difficult for local officials to use state environmental laws.

The Court is interpreting the federal officer removal statute. This law allows private parties to move cases to federal court if they were acting under the direction of a federal officer.

The justices will draft and release a written opinion explaining their decision. This usually happens several months after the oral arguments are completed.

This case is part of a larger trend where the Court decides the boundaries between state and federal power. It specifically looks at where corporations can be held responsible for long-term environmental impacts.
