Chevron USA Inc. v. Plaquemines Parish
The Supreme Court ruled that Chevron can transfer environmental lawsuits about its World War II-era oil-field practices from Louisiana state courts to federal court, because those practices were closely tied to the company's wartime federal contract to produce aviation fuel for the U.S. military.
The decision clarifies how close the connection between a company's conduct and its federal duties must be before a lawsuit can be shifted to federal court under the law that protects federal officers and their contractors.
How it got here: The federal district court sent the case back to Louisiana state court; the Fifth Circuit affirmed; Chevron asked the Supreme Court to hear it and the Court agreed.
The Case in Depth
What happened
Louisiana's Plaquemines Parish and neighboring parishes sued dozens of oil and gas companies under a 1978 state coastal-zone protection law, alleging that decades-old oil-field practices caused lasting environmental damage. The suits focused on activities from the 1940s, including Chevron's use of earthen pits, canals, and vertical-drilling methods during World War II. At the same time, Chevron held a federal contract requiring it to refine crude oil into high-octane aviation gasoline for the U.S. military, a critical wartime need.
The question before the Court
Louisiana parishes sued Chevron over oil-field practices from World War II. Could Chevron move those state-court suits to federal court on the ground that its wartime crude-oil production was connected to its federal contract to refine aviation fuel for the military?
The Court's answer
Yes — Chevron can move the lawsuit to federal court. The Court held that the state-court suit "relates to" Chevron's federal contract duties because its wartime crude-oil production was closely connected to its federally contracted job of refining that oil into aviation fuel. The practices the parish challenged — vertical drilling, earthen pits, and canals — each helped Chevron maximize crude-oil output in service of the military's aviation fuel program, and the government itself had identified Chevron's Louisiana oil fields as critical to the war effort.
The Court rejected two contrary arguments: first, that Chevron's refining contract had to specifically direct its oil-production methods (the statute requires only a genuine relationship, not an express directive); and second, that Louisiana's argument that Chevron had to be "acting under" a federal officer in the specific challenged conduct (that reading would strip the statute's "relating to" language of any independent meaning).

Why it matters
Companies and their corporate descendants that performed wartime or other federal contracts may be able to move state-court environmental or tort suits about those activities into federal court, where federal law defenses are more readily available. The ruling could affect the disposition of dozens of pending coastal-damage suits in Louisiana and potentially reshape environmental litigation against historic federal contractors nationwide.
What changes now
The case goes back to the Fifth Circuit for further proceedings consistent with the Court's interpretation of the "relating to" standard. The federal district court will retain jurisdiction rather than returning the case to Louisiana state court, but Chevron's underlying liability under Louisiana's coastal zone law is still unresolved. The Court expressly declined to decide whether the other oil companies in the related 42 lawsuits can also satisfy the removal statute's requirements.
What this does not decide
The Court did not decide whether Chevron or any other defendant in the related 42 lawsuits is actually liable under Louisiana's coastal zone law, or whether the other requirements of the federal officer removal statute (including the need for a colorable federal defense) are met. The ruling is limited to the meaning of the "relating to" element at the threshold removal stage.

Concurrence — Justice Jackson
Justice Jackson agreed that the lawsuit can be moved to federal court but disagreed with the majority's reasoning. In her view, the Court's 'ordinary meaning' approach to 'relating to' sets a standard that is too loose. She argued that Congress's 2011 addition of 'or relating to' was merely a minor conforming amendment intended to clarify that pre-suit discovery proceedings were covered — not a change to the existing rule requiring a causal (but-for) connection between the challenged conduct and the federal duties. She concluded that Chevron satisfies even the stricter causal-nexus standard on these facts, so she joined the result. Read the full concurrence →
How the Court got there
The legal reasoning, step by step
- The federal officer removal statute allows private companies that worked 'under' a federal officer to move state-court suits to federal court if the suit is 'for or relating to' acts performed in that capacity. The case turned entirely on what 'relating to' means — specifically, how close the connection must be between the challenged conduct and the federal duties.
- The Court interpreted 'relating to' broadly based on its ordinary meaning: one thing can relate to another even if the link is indirect, even if the federal contract did not specifically require the challenged behavior, and even without a strict cause-and-effect relationship. But the connection cannot be trivial — it must be more than 'tenuous, remote, or peripheral.' A butterfly's wing flap does not 'relate to' next week's weather in any meaningful sense.
- Applying that standard, the Court found Chevron's wartime crude-oil production closely connected to its federal contract to refine aviation fuel. The very practices the parish challenged — vertical drilling, using canals instead of roads, and earthen pits — each helped Chevron produce more crude oil faster and with fewer resources, directly supporting its ability to meet the military's aviation fuel demands. The government had even designated Chevron's Louisiana fields as critical to the war program.
- The Court rejected the Fifth Circuit's reasoning that the connection was broken because Chevron's refining contract did not specifically tell it how to obtain crude oil. Under the ordinary meaning of 'relating to,' a federal contract does not need to expressly direct the challenged conduct; the conduct only needs to have a genuine relationship to the federal duties.
- The Court also rejected the argument that the federal government's role as an intermediary — allocating crude oil from producers to refiners — cut off any connection. Drawing on Morales v. Trans World Airlines (a 1992 preemption case), the Court noted that an act can relate to its downstream consequences even when a third party plays a role in the causal chain, just as advertising rules can 'relate to' airline ticket prices even though consumers are the link between the two.
- Finally, the Court rejected Louisiana's alternative theory that the statute only covers conduct performed while 'acting under' a federal officer — which would have required Chevron to have a specific federal contract for its oil production, not just for its refining. That reading would make the statute's 'relating to' language redundant by collapsing it entirely into the separate 'acting under' element.
