The Supreme Court has declined to take up an effort by Republican-led states to revoke California’s authority to set stringent pollution standards for cars and trucks.
In a short order issued Monday, the justices declined to take up a petition from Ohio Attorney General Dave Yost and 17 other Republican state legal officers who challenged California’s Clean Air Act waiver, arguing that it violated the states’ right to equal sovereignty.
The court did not elaborate on its decision, but noted that Justice Clarence Thomas would have granted the petition.

The finding follows the court’s decision Friday to take up the narrow question of whether a coalition of industry groups have standing to challenge the California program in court.
