Supreme Court Weighs Jurisdiction in Climate-Liability Litigation

In Suncor v. Boulder, oral arguments focused on whether the Court can review state-law climate claims against oil companies while the underlying state proceeding remains unfinished. The dispute could affect the Clean Air Act, federalism, local governments' ability to pursue climate claims, and nearly 60 similar lawsuits; Justice Alito's recusal raises the possibility of an eight-justice deadlock or a nonprecedential 4-4 result. A decision is expected by June 2027.
