New York is one of more than two-dozen states and cities suing the Trump administration over its repeal of stricter state emissions standards, the start of what is sure to be a drawn-out legal fight that could get to the U.S. Supreme Court.

In a lawsuit filed in District Court for the District of Columbia on Friday, the 24 attorneys general as well as the cities of New York and Los Angeles allege that the National Highway Traffic Safety Administration acted arbitrarily and capriciously in approving a rule that effectively revoked the state’s standards and that officials didn’t have the authority to make the change in the first place.
