Montana's Supreme Court ruled 5-2 that transgender discrimination is inherently sex discrimination, making transgender people a suspect class under state law—meaning any state law targeting them faces the highest level of judicial scrutiny. The decision blocks SB 458 and related policies that prohibited transgender residents from updating birth certificates and driver's licenses. This effectively hands transgender Montanans stronger constitutional protections in their state than they'd have under federal law, and means future anti-trans legislation will almost certainly fail unless the state can prove a compelling reason for it. Montana has passed significant anti-trans restrictions in recent years, making this ruling a rare reversal of that trend in a state that became a major battleground for both sides.
