The recent U.S. Supreme Court decision in Loper Bright Enterprises v. Raimondo is already influencing new legal challenges. San Francisco has cited Chief Justice John Roberts Jr.’s opinion in this case to support its claim that the U.S. Environmental Protection Agency (EPA) misinterpreted the Clean Water Act. The case in question involves a permit for sewage discharge into the Pacific Ocean. The Court’s ruling in Loper Bright ended the longstanding Chevron deference, which previously required judges to defer to federal agencies’ interpretations of ambiguous laws. San Francisco’s opening brief to the Supreme Court repeatedly references this decision, demonstrating its immediate impact on ongoing regulatory disputes.
