A major ruling by the U.S. Supreme Court Friday that weakened the ability of federal agencies to set rules on the environment, drug safety, consumer protections and other areas could have impacts in California — from vehicle pollution standards to oil and gas drilling on public lands — even though California has its own state laws that are tougher than those in other states and the federal government.

“The decision is an earthquake in U.S. law,” said attorney Michael Wara, director of Stanford University’s Climate and Energy Policy Program, “impacting every single thing, especially every new thing, that any federal agency might want to do to address new problems they are seeking to solve.”
