HELENA, Mont.>> A state judge temporarily has blocked policies that prevented transgender people from changing the GENDER designation on their birth certificates and driver’s licenses.

District Judge Mike Menahan issued his order Monday, blocking the rule while the case moves through the courts.

Menahan said it was not necessary at this point in the litigation to determine whether transgender Montanans constitute a special class on the basis of their transgender status, but he disagreed with the state’s argument that discrimination on the basis of transgender status is not discrimination on the basis of sex.

“If the challenged state actions discriminate against transgender individuals on the basis of their transgender status, they also necessarily discriminate on the basis of sex,” he wrote.

The case was filed in April by two transgender women on behalf of themselves and others who have been unable to obtain documents “that accurately reflect their sex,” the complaint said.

One rule blocks transgender people born in Montana from changing the gender designation on their birth certificate. Another policy prevents transgender residents from changing the gender on their driver’s licenses without an amended birth certificate — which they can’t obtain if they were born in Montana.

Plaintiff Jessica Kalarchik, who was born in Montana, said in a statement Tuesday that she was frustrated that while “being able to live my life openly as the woman I know myself to be,” Montana “wants me to carry around a birth certificate that incorrectly lists my sex as male.”

Birth certificates and driver’s licenses are needed to apply for a marriage license or a passport, to vote or even to buy a hunting license, Alex Rate, legal counsel for the American Civil Liberties Union of Montana, argued last month. Each time a transgender person is required to produce a document that does not accurately reflect their gender, they are forced to “out” themselves as transgender.

The state had argued that gender is binary, either male or female, and that being transgender is not a protected class of people who could have their constitutional rights to privacy violated.

“The right to privacy does not include a right to replace an objective fact of biological sex on a government document,” assistant attorney general Alwyn Lansing argued.

Chase Scheuer, spokesperson for the Department of Justice, which includes the motor vehicle division, said: “The judiciary has once again defied the democratic will of Montanans by siding with special interest groups and the left’s radical leftist ideology.” The agency hasn’t decided whether it will appeal the injunction.

The state health department, which issues birth certificates, does not comment on pending litigation, spokesperson Jon Ebelt said.

The case is the latest volley in a series of laws, rules and legal challenges over efforts by Republicans in Montana and many other states to limit the rights of transgender residents. The state has used various justifications in banning changes to identifying documents, including needing accurate statistical records or saying someone’s biological gender cannot be changed even though someone’s gender identity can.

“The state cannot articulate any legitimate interest in restricting access to accurate identity documents, much less a compelling one,” Rate argued during the hearing before Menahan in November.

In late 2017, under Democratic Gov. Steve Bullock, the state health department implemented a rule allowing people to change the gender on their birth certificate by signing an affidavit.
