In re Gray and Rice
This opinion, authored by Justice Himonas, deals with the right of transgender individuals to change their legal sex designation on their birth certificates. This case was an appeal by two transgender individuals—Sean Childers-Gray, a transgender man, and Angie Rice, a transgender woman—who had petitioned the Utah District Court for the right to change both their name and sex designation on their birth certificate. The District Court granted the name change but refused the sex change. Justice Himonas, and a majority of the Utah Supreme Court ultimately found that "A person has a common-law right to change facets of their personal legal status, including their sex designation." This decision rested upon the common-law right to change one's own name as well as a Utah statute that tied sex designation changes to name changes.
