Montana Supreme Court

Kalarchik v. State

April 14, 20262026 MT 76

Summary

The Court affirmed a preliminary injunction barring enforcement of state policies that prevented transgender individuals from amending the sex designations on their birth certificates and driver's licenses. It held that at least one plaintiff established concrete injury and that the district court did not manifestly abuse its discretion in finding each statutory preliminary-injunction factor satisfied, including a sufficient likelihood that the policies discriminate based on sex under Montana's Constitution. The Court emphasized that the ruling was preliminary and did not resolve the ultimate merits of the constitutional claims.
