The US Supreme Court refused to put a challenge to President Donald Trump’s sweeping tariffs on an ultra-fast track.

The U.S. Supreme Court sided on Friday with fuel producers that had opposed California's standards for vehicle emissions and electric cars under a federal air pollution law, agreeing that their legal challenge to the mandates should not have been dismissed.

The 7-to-2 decision stressed that it did not address the merits of the dispute, and concerned only whether the producers had standing to sue.
