Florida just hit a dead end at the nation's highest court. The Supreme Court on Tuesday refused to let Florida sue California and Washington over their policies allowing certain undocumented immigrants to obtain commercial driver's licenses, a case that grew out of an August 2025 crash in Florida that killed three people, reports USA Today. The truck driver in that accident, Harjinder Singh—who officials say entered the US illegally and held commercial licenses from Washington and then California—has pleaded not guilty and has not yet gone to trial. Florida argued that those states were putting other states' residents at risk by licensing drivers who allegedly lacked proper training and English skills, and sought to block them from issuing such licenses at all.
The justices rejected the request without explanation. Only Clarence Thomas and Samuel Alito said they would have heard the case, with Thomas noting that the "court declines to even hear Florida's claims, even though it has nowhere else to bring them," per NBC News. Lawyers for California and Washington labeled the lawsuit a "political stunt" and said such disputes should go through federal regulators, warning that otherwise states could start suing each other over everything from vaccine rules to gun laws. "The Court should not open that door," wrote Washington AG Nicholas Brown, adding that Florida is "seeking to distract from its own incompetence." Florida AG James Uthmeier countered that "California's and Washington's decisions to endanger their own citizens is reprehensible. But commercial drivers routinely cross state lines, endangering citizens of other States."
