Oklahoma Gov. Stitt signed SB 1100, barring nonbinary sex designations on birth certificates
On April 26, 2022, Oklahoma Gov. Kevin Stitt signed Senate Bill 1100, amending the state's vital-records statutes to require that the biological sex designation on a birth certificate be either male or female and expressly prohibiting a nonbinary designation or any symbol representing one, including "X." The bill carried an emergency clause and took effect immediately, reversing a nonbinary-marker option the Oklahoma State Department of Health had begun permitting the prior year under a lawsuit settlement.
