Modifies provisions relating to gender designations on state-issued identity documents

HB 157 requires state agencies to list a person's gender on identity documents (like driver's licenses) based solely on biological sex, defined as determined by sex chromosomes. It prohibits changing gender designations based on self-identification, medical procedures, or hormones, and mandates reissuing documents if the gender doesn't match biological sex. Exceptions apply for individuals with medically verified disorders of sex development (e.g., ambiguous external characteristics or specific genetic conditions). The bill directly affects people seeking or holding state-issued IDs, particularly transgender and intersex individuals, by restricting how gender markers can be updated. It does not apply to birth certificates or other documents covered under separate provisions.
