American Gas Association v. U.S. Department of Energy

Three trade associations and a company that manufactures and sells gas-powered furnaces and other appliances filed a petition for writ of certiorari seeking U.S. Supreme Court review of a D.C. Circuit decision upholding Biden-era amendments to the energy efficiency standards for consumer furnaces and commercial water heaters. The petitioners presented two questions: (1) “[w]hether courts may defer to an agency’s legal interpretation of a statute because an agency applied the statute to undisputed facts, despite this Court’s holding in Loper Bright Enterprises v. Raimondo that courts must construe statutes without deference to agency statutory interpretations” and (2) “whether an appliance’s ability to operate in existing homes and buildings without renovation is a ‘performance characteristic’ that [the Energy Policy Conservation Act] prohibits the Department [of Energy] from eliminating.”
