Montana health officials on Friday made permanent a rule that blocks transgender people from changing their birth certificates even if they undergo gender-confirmation surgery. The move by Republican Gov. Greg Gianforte’s administration comes just days before a court will hear arguments over the legality of a similar rule that’s been in effect on an emergency basis since May. The ACLU of Montana has asked state Judge Michael Moses to strike down the emergency rule. Moses in April had temporarily blocked a 2021 Montana law that made it difficult for transgender people to change their birth certificate. The law said people had to have a “surgical procedure” before they could change the sex listed on their birth certificate. Gianforte’s administration then went further and blocked changes to birth certificates even after surgery.
