DOJ sues California over truck emissions standards after Congress kills waivers

The Justice Department filed suit against California, arguing the state's truck emissions standards were preempted after Congress used the Congressional Review Act to rescind EPA waivers that had permitted California to set stricter vehicle emissions rules. California Attorney General Rob Bonta countered that the CRA cannot be used to revoke Clean Air Act waivers and that the state's authority under Section 209 remained intact. The case set up a direct constitutional conflict over whether Congress or the EPA holds final authority over state emissions derogations.
