Decided
Docket Number
Lower Court Opinion
Questions Presented
- Whether 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. 603 U.S. 369, 395 (2024).
- Whether an appliance’s ability to operate in existing homes and buildings without renovation is a “performance characteristic” that EPCA prohibits the Department from eliminating. 42 U.S.C. §§ 6295(o)(4); 6313(a)(6)(B)(iii)(II)(aa).
