Liberal justices join Clarence Thomas in unanimous Supreme Court ruling for Chevron

The U.S. Supreme Court sided unanimously with Chevron on Monday in a Louisiana coastal-damage case, with all three liberal justices joining conservative Justice Clarence Thomas's opinion, a rare alignment that kept a high-stakes environmental lawsuit in federal court and handed the oil giant a major procedural win.

The 8-0 ruling vacated a Fifth Circuit decision and sent the case back to the appeals court, giving Chevron and other oil and gas companies another shot at defending themselves on friendlier federal turf. Justice Samuel Alito did not participate.

The case, Chevron USA v. Plaquemines Parish, turns on a narrow but consequential question: whether Chevron's World War II-era oil production, carried out under federal direction to supply aviation gasoline for the U.S. military, entitles the company to move a state-court lawsuit into federal court under the federal officer removal statute. Thomas, writing for the Court, said it does.

Thomas's opinion draws full bench

What makes the ruling notable is not just the outcome but the lineup. Justices Elena Kagan, Sonia Sotomayor, and Ketanji Brown Jackson, the Court's three liberal members, all agreed with the result. Kagan and Sotomayor joined Thomas's opinion outright. Jackson concurred separately, agreeing the case belonged in federal court but cautioning against reading the statute too broadly.

Chief Justice John Roberts and Justices Neil Gorsuch, Brett Kavanaugh, and Amy Coney Barrett also joined Thomas. Newsweek reported that the decision was unanimous among the eight participating justices, a striking consensus on a case with billions of dollars and dozens of similar lawsuits hanging in the balance.

Thomas wrote plainly in the majority opinion:

"Chevron's case fits comfortably within the ordinary meaning of a suit 'relating to' the performance of federal duties. Chevron has plausibly alleged a close relationship between its challenged conduct and the performance of its federal duties, not a tenuous, remote, or peripheral one."

That language matters. The federal officer removal statute allows defendants to move cases into federal court when the claims arise "for or relating to any act under color of such office." The Fifth Circuit had read that standard more narrowly. The Supreme Court disagreed, and did so without a single dissent.

The Court's willingness to speak with one voice here stands in contrast to the sharp ideological splits that have defined much of the current term. On issue after issue, redistricting, executive authority, social policy, the justices have fractured along familiar lines. This was different.

What the case is really about

Louisiana parishes filed lawsuits in 2013 against oil and gas companies, including Chevron, under the state's 1978 Coastal Resources Management Act. That law prohibited certain uses of Louisiana's coastal area, including oil production, without a permit. The parishes alleged that decades of drilling, dredging, and pipeline construction had devastated the state's coastline.

The numbers are staggering. The U.S. Geological Survey has reported that Louisiana's coastal parishes have lost more than 2,000 square miles of land over the past century, with oil and gas infrastructure identified as a major cause. A prior state jury verdict ordered Chevron to pay roughly $740 million for coastal restoration, a figure Breitbart noted could now be jeopardized by the Supreme Court's ruling.

Chevron removed the lawsuit from state court, arguing that its wartime oil production was carried out under federal direction. The company pointed to its role refining crude oil into aviation gasoline for the U.S. military during World War II. Thomas agreed, writing that Chevron "act[ed] under federal officers when it performed its refining duties."

The Washington Examiner reported that a Chevron spokesperson, Bill Turenne, said the company "applauds the Supreme Court's unanimous judgment recognizing that these lawsuits belong in federal court." A separate company statement added: "Chevron looks forward to litigating these cases in federal court, where they belong."

Jackson's separate concurrence

Justice Jackson's decision to write separately deserves attention. She agreed the case belonged in federal court but warned against an overly broad reading of the removal statute. Her concurrence focused on the phrase "under color of [federal] office," suggesting the Court should be careful not to let any company with a wartime contract strip cases out of state court indefinitely.

That concern is not trivial. If the "relating to" standard is read too loosely, virtually any company that performed contract work for the federal government decades ago could invoke the statute to escape state-court liability. Jackson wanted to draw a line. But she still joined the result, which tells you how strong Chevron's position was on the facts.

Jackson has drawn scrutiny from conservatives on other fronts, including Senator Blackburn's call for an ethics probe after Jackson attended a politically charged awards ceremony. But on this case, she landed squarely with the majority.

The Trump administration's role

President Donald Trump's administration backed Chevron and other oil and gas companies in the case. That alignment is consistent with the administration's broader posture toward domestic energy production and its skepticism of state-level litigation used to impose environmental policy through the courts rather than through legislation.

The ruling does not resolve the underlying liability question. Chevron still faces claims that its operations damaged Louisiana's coastline. But the venue matters enormously. Federal courts apply different procedural rules, different evidentiary standards, and, critically, different juries. For companies facing hundreds of millions in potential damages, the forum can shape the outcome as much as the merits.

Thomas made that point implicitly. He noted that an expert report filed by Plaquemines Parish "made clear" that the parish intended to challenge some defendants' crude oil production during World War II. That admission, Thomas wrote, tied the lawsuit directly to conduct performed under federal authority, and that connection satisfied the removal statute.

Just The News reported that Thomas also wrote: "Chevron's federal contracts can be a but-for cause of the challenged crude-oil production without specifically directing that production." In other words, the federal government didn't need to have ordered every barrel pumped. The wartime relationship was enough.

Broader implications for energy litigation

The ruling lands at a moment when oil and gas companies face a wave of climate-related lawsuits filed in state courts across the country. Plaintiffs' lawyers have favored state venues for years, calculating that sympathetic local juries and favorable state tort law give them leverage that federal court does not. Monday's decision chips away at that strategy.

The AP reported that the decision gives Chevron "another chance" after the $740 million-plus jury verdict, and noted the procedural nature of the ruling. But procedural rulings in high-stakes litigation are rarely just procedural. Moving a case from a parish courtroom to a federal bench can change everything, the discovery process, the applicable law, and the political dynamics of the trial.

The Supreme Court has been active this term in ways that have surprised observers on both sides. But the unanimity here is the real story. When Thomas, Kagan, Sotomayor, and Jackson all sign onto the same bottom line, the legal argument is either overwhelming, or the alternative was untenable.

The Fifth Circuit will now reexamine the case using the Supreme Court's guidance. Whether Chevron ultimately prevails on the merits remains an open question. But the company will fight that battle in a forum of its choosing, not the plaintiffs'.

The current Supreme Court term has produced no shortage of contentious, closely divided opinions. This was not one of them. And that unanimity tells you something the ideological scorekeepers rarely admit: sometimes the law is just the law, and the right answer doesn't come with a party label.

When all eight participating justices agree that a company acting under federal wartime orders deserves a federal courtroom, the only people surprised are the ones who assumed the Court can never rise above politics.
