Federal judge blocks EPA effort to rescind California vehicle emissions waivers

A preliminary injunction preserves California's clean air rules after the EPA and congressional Republicans attempted to use the Congressional Review Act to nullify them.

The short version

  • A federal judge in Washington, D.C., issued a preliminary injunction preventing the EPA from rescinding California's vehicle emissions waivers.
  • The ruling protects California's light- and heavy-duty vehicle emissions standards while legal challenges proceed.
  • The court determined that the clean air waivers are adjudicatory orders rather than rules, making them ineligible for nullification under the Congressional Review Act.
  • The lawsuit will proceed to a full trial on the merits, though the judge noted California is likely to succeed.
