What it's about
The Supreme Court agreed to hear the case, wiped out the appeals court’s judgment (vacated it), and sent the case back (remanded it) for reconsideration in light of the Solicitor General’s position; it did not decide the underlying questions.
The dispute concerns federal rules for gas furnaces, including whether they must work in existing buildings without renovation.
Question presented
1. 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. 2. 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.
What the Court decided
Holding
Petition granted. Judgment vacated and case remanded for further consideration in light of the position asserted by the Solicitor General in his brief for the United States filed on April 28, 2026.
- Result
- Remanded
What's next
The case returns to the D.C. Circuit for further consideration in light of the Solicitor General’s position in the government’s April 28, 2026 brief.
