On Thursday, the President signed three Congressional Review Act (CRA) resolutions that effectively prevent California from implementing its zero emission mandates for passenger vehicles and commercial trucks and its stricter emission standards for heavy-duty vehicles. Previously, the Government Accountability Office and the Senate Parliamentarian determined that the Biden Administration EPA’s approvals of these mandates were waivers from federal (Clean Air Act) preemption and not rules for CRA purposes, but the House and Senate nevertheless passed all three resolutions. In signing the resolutions into law, President Trump proclaimed that the resolutions “prohibit the EPA from approving future waivers for California that would impose California’s policy goals across the entire country. . . ending the electric vehicle mandate for good.” That same day, the State of California and ten other states filed suit in a federal district court in California, challenging the three CRA resolutions as unconstitutional and contrary to multiple federal statutes.
