Consumer Watchdog Questions Alito's Role in Supreme Court's Decision to Hear Suncor Case

Consumer Watchdog has raised questions regarding Justice Samuel Alito's potential role in the Supreme Court's decision to grant review in the Suncor v. Boulder case. The organization suggests that Alito's last-minute and unexplained recusal from the case in September 2026, just before oral arguments, raises doubts about his initial involvement.

The Suncor v. Boulder case addresses the pivotal question of whether federal law precludes state-law claims seeking redress for injuries allegedly caused by emissions. The Supreme Court granted certiorari in February 2026, and Alito is known to have participated in that decision under the "Rule of Four," which requires at least four justices to vote to hear a case.

Consumer Watchdog highlights a contrast with the case Sunoco v. Honolulu, which the Supreme Court denied review in January 2025. In that instance, Alito had recused himself throughout the Court's consideration of the petition. The core legal question presented in both cases was virtually identical, concerning federal preclusion of state-law climate claims.

"We know Alito was recused when the Court declined to hear Honolulu, and we know he was participating when the Court decided to hear Suncor. What we don't know is how he voted or whether there would have been four votes to take Suncor without him," said Alexandra Nagy, Organizing Director of Consumer Watchdog. She added that Alito's subsequent recusal makes these unanswered questions impossible to ignore.
