A federal judge on Tuesday tossed the remainder of a legal challenge automakers brought against a motor vehicle repair law Massachusetts voters approved more than four years ago.

U.S. District Court Judge Denise Casper dismissed the final two counts in a lawsuit alleging the state’s so-called right to repair law conflicts with preexisting federal law, prompting the measure’s supporters to celebrate that challenges “have finally come to an end” and automakers to hint that certain vehicles “may no longer be offered for sale in Massachusetts” as a result.

The law, which aims to give vehicle owners and independent repair shops access to telematic repair data, has faced a long and tumultuous road since voters approved it by a roughly three-to-one margin in 2020.
