Decision
Defendants-appellants' motion to postpone the oral argument denied.
The Sixth Circuit Court of Appeals denied the Trump administration’s motion to postpone the oral argument scheduled for February 5, 2025 in the Federal Highway Administration (FHWA) and other defendants’ appeal of an April 2024 district court ruling that the FHWA exceeded its statutory authority and acted arbitrarily and capriciously when it adopted a regulation requiring states to establish declining targets for carbon dioxide emissions from on-road mobile sources. The defendants requested that the oral argument be postponed and the case held in abeyance to allow the agencies “to become familiar with the final rule and the issues presented by this litigation and to determine how they wish to proceed.”
