On April 16 and 20, petitioners filed two requests asking the court to defer the call for merits briefing proposals until EPA addresses four reconsideration petitions that ask EPA to hold a comment period on modeling and other material on which the final rule relied for its conclusion that regulation of vehicle greenhouse gases would be futile. One request asked that the call for briefing proposals be deferred until at least June 4, 2026 or until EPA decides whether to grant the reconsideration petitions. The other request, by the petitioners in the lead proceeding, requested that the court grant a deferral of 90 days (to July 20, 2026), which they indicated could allow EPA to fully resolve the reconsideration petitions.

Challenges to the U.S. Environmental Protection Agency’s final rule rescinding the 2009 greenhouse gas endangerment finding under the Clean Air Act and repealing all greenhouse gas emission standards for motor vehicles and engines.
