The Supreme Court delivered a unanimous verdict against environmental plaintiffs on Friday, allowing Chevron USA to contest a Louisiana coastal damage lawsuit in federal court, rather than in the state court that previously issued a nearly $750 million judgment against the company.
In the case of Chevron USA Inc. v. Plaquemines Parish, the Court’s 8-0 decision nullified a prior ruling by the Fifth Circuit, sending the case back to the lower courts for further consideration. Justice Clarence Thomas authored the opinion, with six other justices concurring. Justice Ketanji Brown Jackson agreed with the judgment but wrote separately. Justice Samuel Alito abstained from the case due to his financial interests in ConocoPhillips, a parent company involved in the lower court proceedings.
Back in 2013, Plaquemines Parish initiated one of 42 lawsuits in state courts against various oil and gas companies, invoking Louisiana’s State and Local Coastal Resources Management Act from 1978. The parishes claimed that certain oil production activities, some dating as far back as the 1940s, lacked necessary permits or were started illegally, hence not covered by the law’s grandfather clause for operations before 1980.
What the Case Was Actually About
The crux of the argument lies in the fact that many of these disputed activities occurred during World War II. At that time, Chevron’s predecessor, the Texas Company, was fulfilling a federal contract to produce aviation gasoline for the U.S. military. The Petroleum Administration for War had taken control of the oil industry, dictating production techniques, designating crude oil to specific refineries, and urging companies to optimize output at all costs.
Plaquemines Parish now labels these wartime production techniques as environmental infractions. However, methods like vertical drilling, using earthen pits instead of steel tanks, and canal dredging rather than road construction were either mandated or strongly promoted by the federal government to ensure a steady supply of aviation fuel for military aircraft.
The production practices Plaquemines Parish now characterizes as environmental violations, including vertical drilling, earthen pits instead of steel tanks, and canal dredging instead of road construction, were methods the federal government either required or actively encouraged to keep avgas flowing to American aircraft.
The Legal Question
The federal officer removal statute, 28 U.S.C. §1442(a)(1), allows companies that were “acting under” a federal officer to move state-court suits against them to federal court, provided those suits relate to actions taken in their capacity as federal contractors. The question before the Court was whether the parishes’ challenge to Chevron’s wartime crude oil production “related to” Chevron’s federal contract to refine that oil into avgas.
The Fifth Circuit said no. It reasoned that Chevron’s refining contract didn’t specifically address how to acquire crude oil, so the production activities were a separate matter unconnected to the federal contract.
Justice Thomas, writing for the Court, rejected that reading as too narrow. “The phrase ‘relating to’ sweeps broadly,” he wrote, and does not require that federal duties “specifically required or strictly caused the challenged conduct.” What matters is whether the connection is close, not tenuous, remote, or peripheral.
The Court found that the connection was plainly satisfied here. The crude oil Chevron produced in the Delta Duck Club field in Plaquemines Parish fed directly into the avgas refining operation it was conducting for the military. The Petroleum Administration for War had designated that field as critical to the war program because of the quality of its crude oil for avgas production. The government’s own directives required the very vertical drilling methods the parishes now seek to litigate as violations.
“In this all-hands-on-deck, wartime context,” the Court wrote, “Chevron needed to produce more crude oil as quickly as possible to facilitate more avgas refining, including its own.”
Why Federal Court Matters
The venue question carries real stakes. A state jury in Plaquemines Parish, made up of residents of the community that the lawsuit says was harmed, had already returned a verdict of nearly $745 million against Chevron. Federal courts apply uniform standards and are not subject to the same geographic pressures that can pull local juries toward local grievances.
The Trump administration backed Chevron’s position in this case. Supporters of Chevron’s argument, including retired military officers, warned that allowing state courts to second-guess the production decisions of wartime federal contractors would undermine the federal government’s ability to recruit private companies for national security work in future crises. If a company can be sued in a local court for following the government’s directives during wartime, the argument goes, fewer companies will be willing to answer the call.
Implications Beyond Plaquemines
The ruling does not resolve the underlying environmental claims. It determines only where those claims will be litigated, not whether they will succeed. Chevron has consistently denied responsibility for coastal land loss in Louisiana, arguing it cannot be held liable under environmental regulations that did not exist when the challenged activities occurred.
According to John Carmouche, the attorney for Plaquemines Parish, the decision directly affects 11 of the 42 suits filed in 2013, those involving wartime federal contractor arguments similar to Chevron’s. The remaining 31 are expected to stay in state court. Several of the defendants in those 11 cases made parallel removal arguments based on their own wartime federal contracts. The Court’s reading of “relating to” gives those companies a path to push their cases into federal court as well.
Carmouche, expressing disappointment in the ruling, said a jury of residents decided the case “after hearing the overwhelming evidence,” and that the Court had concluded that “the people of Plaquemines did not have the right to make this decision.” He vowed to continue the fight in federal court.
Chevron welcomed the ruling. “As the Court recognized,” a company spokesman said, “the plaintiffs’ claims are related to activities that Chevron and other energy companies performed under federal supervision during World War II.” The company said it “looks forward to litigating these cases in federal court, where they belong.”
The Broader Pattern
Environmental groups have leaned on state courts to pursue liability claims against the fossil fuel industry. This has been evident in Louisiana, in cities suing over climate change, and elsewhere else. The calculation has been that local juries, local judges, and local political pressures tilt those venues in their favor.
Thomas’s opinion was careful to note that the ruling does not determine the outcome on the merits. The case goes back to lower courts for further proceedings. The environmental plaintiffs who spent over a decade steering these cases into Louisiana state courts will now have to make their arguments in a very different arena.
