Chevron U.S.A. Inc. v. Plaquemines Parish

On April 17, 2026, the Supreme Court vacated a Fifth Circuit decision that narrowly interpreted the federal-officer removal statute to deny federal contractors access to federal courts. The decision was a victory for WLF, which argued in an amicus brief that the appeals court’s contractual-direction requirement revived a discarded causal-nexus test and upended the broad “relating to” standard Congress established in 2011. In an 8-0 decision, the Court agreed, holding that defendants’ production, tied to federal wartime needs through pricing, tax exemptions, and allocations, satisfied this standard. Atlantic Legal Foundation joined WLF on the brief.
