Marquez v. State of Montana
Amelia Marquez is transgender woman and life-long Montanan. John Doe is a transgender man who was born in Montana, but currently lives out of state. Both wish to correct the sex marker on their birth certificates to reflect who they are. However, a law enacted in 2021, Montana Senate Bill 280, sought to prohibit transgender individuals born in Montana from correcting the sex marker listed on their birth certificate without obtaining a court order indicating that their “sex . . . has been changed by surgical procedure.” The ACLU, the ACLU of Montana, and Nixon Peabody LLP have sued, claiming that SB 280 violates the equal protection and due process clauses of the Montana State Constitution.

City of Kalispell v. Doman
This case asks whether the state can arrest, charge, and convict someone under Montana’s obstruction statute for exercising their federal and state constitutional right to record police officers in public spaces. The defendant was filming a traffic stop when police instructed him to move farther away. When he did not move as far as they wanted, they arrested him for obstructing a peace officer. The ACLU’s State Supreme Court Initiative, along with the ACLU of Montana, filed an amicus brief in support of the defendant arguing that the officer’s refusal to allow the defendant to peacefully record police activity from a public sidewalk was, in effect, a content-based restriction on speech that could not be justified under strict scrutiny. Even if the restriction was not content-based, our brief argues that it is not a reasonable time place or manner restriction.

Kalarchik v. Montana
After a years-long effort by the state of Montana to deny transgender people the right to update their identity documents, two transgender women filed a class-action lawsuit against the state and several of its agencies and officials. 26 states and the District of Columbia issue new birth certificate and do not require sex reassignment surgery nor court order in order to change gender marker, while Montana is one of five states that prohibits any changes.

Western Native Voice v. Jacobsen
The American Civil Liberties Union, ACLU of Montana, Native American Rights Fund (NARF), and the Harvard Election Law Clinic challenged two Montana laws that hinder Native American participation in the state’s electoral process — HB 530, which prohibited paid third-party ballot collection; and HB 176, which repealed Election Day voter registration (EDR) in Montana. Together, these laws violate a number of provisions in the Montana Constitution: the right to vote, equal protection, free speech, and due process.
