The U.S. Supreme Court on April 17, 2026 handed Chevron a significant procedural victory in long-running Louisiana coastal-damage litigation, unanimously ruling that the company may pursue removal to federal court in a major suit brought by Plaquemines Parish. The decision does not resolve the merits of the parish’s land-loss and environmental damage claims, but it strengthens a key defense strategy in a wave of cases targeting oil and gas operators for decades of coastal erosion and wetlands degradation.

The case, Chevron USA Incorporated, et al., Petitioners v. Plaquemines Parish, Louisiana, et al., has been closely watched because Louisiana’s coastal suits have produced enormous exposure risk.

The U.S. Supreme Court has agreed to hear a closely watched dispute over whether state and local governments can continue pursuing climate-change tort claims against oil and gas companies in state court. The case arises out of Colorado litigation brought by local governments seeking to recover damages tied to alleged climate impacts, including costs associated with extreme weather, wildfire risk, and other harms.

At the center of the fight is a recurring threshold issue in climate-liability litigation: forum.
