For the first time, the U.S. Supreme Court has granted oil companies’ request to weigh in on whether climate accountability lawsuits are preempted by federal law — setting the stage for a battle that could determine if dozens of similar cases are allowed to move toward trial.
The decision means the court will hear arguments from ExxonMobil and Suncor Energy to overturn an earlier ruling by the Colorado Supreme Court, which decided that a case brought by Boulder, Colorado, could move ahead in state court. You can read more about the companies’ petition in ExxonKnews and DeSmog’s previous coverage here.
Oil companies have previously and repeatedly asked the Supreme Court to take up issues in the lawsuits, which point to growing evidence that the companies spent decades deceiving the public about climate change and blocked the transition to renewable energy. Since a narrow procedural ruling in 2021, the companies were rejected each time.
But two factors were different this time: the Trump administration urged the justices to take the oil companies’ petition in Boulder’s case, and Justice Samuel Alito participated in discussion of the case, despite recusing himself in the past.
