A One-Sentence Recusal
Supreme Court Associate Justice Samuel Alito recused himself Monday from Suncor Energy v. County Commissioners of Boulder County, a major climate case scheduled for oral arguments one week later. Supreme Court Clerk Scott Harris told the parties that Alito, an appointee of former President George W. Bush, “has determined that he will not continue to participate in this case.” That was the entire message. The letter stated the decision but gave no explanation. In an institution famous for turning short questions into long opinions, the notice was concise to a fault. It also leaves the public with no stated reason for why Alito will no longer take part.
The Stock Question
Alito owns stock in several oil and gas companies, although not in either Suncor Energy or ExxonMobil, the two companies involved in the case, according to Reuters. Watchdog and environmental groups had urged him to recuse himself, and he initially resisted those calls. He had also stepped aside when the litigation reached the Supreme Court at an earlier stage in 2023. Forbes, citing 2025 financial disclosures, reported that Alito held thousands of dollars in stock in Phillips 66, OGE Energy Corp., Black Hills Corp., BHP Group, Fortis Inc., ConocoPhillips, Woodside Energy Group and AES Corp. The holdings do not establish a legal conclusion by themselves, but they help explain why the recusal became a public issue rather than a routine line in the court calendar.
What Boulder Is Asking For
Boulder County and the City of Boulder sued Suncor and ExxonMobil in 2018. They allege that the companies’ production, promotion and sale of fossil fuels contributed to climate change and caused local harms. The governments brought claims under Colorado law, including public and private nuisance, trespass, unjust enrichment and civil conspiracy. The Colorado Supreme Court allowed the lawsuit to move forward in 2025, setting up a fight over whether a state can use its own tort law to seek damages tied to greenhouse gas emissions produced around the world. Suncor and ExxonMobil argue that claims involving interstate and international emissions are governed by federal law and cannot be imposed through one state’s tort system.
A Case With National Stakes
The Supreme Court’s October argument calendar schedules the case for Oct. 5, and it is set to be the first case argued when the court begins its 2026 term. Roughly 20 amicus briefs have been filed. Environmental groups and Democratic-led governments are backing Boulder, while free speech advocates warn that liability based partly on corporate public statements and political advocacy could raise First Amendment concerns. The dispute therefore reaches beyond one Colorado lawsuit. A ruling could affect similar climate cases across the country and determine how much room states have to pursue fossil fuel companies over alleged harms linked to global emissions. The legal stakes are large, even if the clerk’s letter was remarkably small.
The Litigation Strategy May Shift
Climate litigation advocates have discussed using consumer protection laws and state tort claims to continue pursuing fossil fuel companies if the Supreme Court limits lawsuits like Boulder’s. That means the legal campaign may not end with one ruling. It could simply move to a different statute, a different courtroom or a different theory of liability. Supporters see those tools as ways to seek compensation for climate-related harms. Critics see a potential workaround that could let state lawsuits reach conduct and emissions spanning the country and the globe. Either way, the case is about more than whether Boulder can proceed. It may help define how far state-level climate litigation can go before federal law steps in.
Scrutiny Around Judicial Connections
Alito’s recusal also comes as the climate litigation network faces scrutiny over connections involving judges, academics and advocacy groups. In Hawaii, a watchdog group has sought records about interactions through judicial education programs. Former Hawaii Supreme Court Chief Justice Mark Recktenwald previously disclosed taking part in environmental education programs connected to the Environmental Law Institute, which co-founded the Climate Judiciary Project. A records request is not a finding of misconduct, but it shows why questions about judicial education and advocacy networks keep returning. The Supreme Court Public Information Office did not immediately respond to a request for comment from the Daily Caller News Foundation.
