The U.S. Court of Appeals for the Second Circuit on Monday halted an attempt by the Trump administration to delay implementation of new penalties for automakers that fail to meet fuel efficiency standards.

The decision by a panel composed of Circuit Judges Ralph Winter, Rosemary Pooler and Barrington Parker represents a win for states including New York, California and Pennsylvania, as well as environmental groups that joined them in arguing the National Highway Traffic Safety Administration lacked authority and violated a number of federal statutes in delaying implementation of the penalty rule.

“The fuel efficiency standards penalty rule is a common sense measure that would protect consumers' pocketbooks while reducing the carbon emissions that harm our health and drive climate change,” New York State Attorney General Eric Schneiderman said in a statement. “As we've proven again and again, when the Trump administration puts special interests before public health and our environment, we'll take them to court—and we will win.”
