The Supreme Court’s October calendar just got a little more interesting — and a lot more unpredictable. Suncor Energy v. County Commissioners of Boulder County will open the Court’s term on October 5, but the case will proceed without one of the nine justices. That sudden recusal changes the math and raises real questions about whether a divided court will set a national rule on climate lawsuits or punt the issue back to the states.
Alito recusal shifts the balance before arguments
Clerk of the Supreme Court Scott S. Harris sent a one‑sentence notice to counsel: “Justice Alito has determined that he will not continue to participate in this case.” That short line matters. With Associate Justice Samuel Alito stepping aside, only eight justices will argue Suncor v. Boulder on October 5. An eight‑justice panel can deadlock 4–4, which would simply leave the Colorado Supreme Court’s decision in place without creating a national precedent. In other words, a big legal question about climate liability could be decided by who shows up — not by who’s right.
What the case is really about: federal law vs. state torts
At its heart Suncor v. Boulder asks whether state and local courts can use ordinary tort law to hold oil and gas companies responsible for local harms tied to greenhouse‑gas emissions. Petitioners say federal law and foreign‑affairs concerns should block these state suits. Supporters of Boulder, including a bipartisan group of former federal climate officials, argue that blocking state law would require an affirmative act of Congress. The Court’s ruling could either protect state police powers or blunt them in favor of national uniformity — a big deal for federalism and for energy companies facing dozens of similar suits.
Why lawmakers and the energy industry are watching
Senator Kevin Cramer has sounded the alarm, calling the prospect of state lawsuits “anti‑capitalism” and warning that a patchwork of state rules would strangle energy production in places like North Dakota and Alaska. Industry and some lawmakers are also pointing to pending Senate permitting reforms that would shorten the window for judicial challenges to certain federal approvals to about 150 days. But don’t confuse federal permitting timelines with state tort law — they are different tools. Still, both debates show that Congress and the courts are under pressure to limit litigation that industry says delays projects and raises costs for consumers.
What a 4–4 split would mean — and why conservatives should care
If the Court splits 4–4 because of Justice Alito’s recusal, the Colorado decision allowing Boulder’s claims to go forward would stand, and dozens of similar cases could keep chugging along in state courts. That outcome would be a victory for trial lawyers and climate activists, but a headache for businesses and for anyone who believes national economic policy shouldn’t be determined by 50 different state courts. Conservatives should want clear rules: either Congress acts, or the Court issues a nationwide rule. A tied decision leaves chaos in place and hands leverage to plaintiffs who can use discovery to punish companies long before any merits test is applied.
Bottom line: Suncor v. Boulder was already a court test with huge stakes for energy, federalism, and the limits of state tort law. Justice Alito’s recusal turns the case into a live experiment in judicial math. Watch October 5 closely — because the outcome may tell us whether the Supreme Court will bring clarity or simply move the fight back to the trenches of state courts and long, expensive discovery battles.
