"WASHINGTON -- California and like-minded states are girding for a legal battle with the Trump administration on whether those states have gone too far in controlling greenhouse gases from automobiles, a prospective case that legal scholars say — barring a last-minute settlement — is sure to reach the U.S. Supreme Court.

The Environmental Protection Agency and other federal agencies are expected to announce, as soon as this week, a rollback of national fuel economy standards for vehicles. They could also revoke California’s ability to set its own, tougher, air pollution limits.

If the Trump administration challenges California’s longstanding latitude to set its own emissions rules, it would be wading into untested legal waters, said Deborah Sivas, a law professor and expert on the Clean Air Act at Stanford University."
