What it would have done
Summary by the , the Legislature's nonpartisan drafting office. It's their wording, not ours.
Current law allows for changes to an individual’s sex on a birth record due to a surgical sex-change procedure or to correct an error on a birth record, subject to certain requirements. Under this bill, an individual’s sex on a birth record may not be changed due to a surgical sex-change procedure. Moreover, the bill prohibits any person from changing an individual’s sex on a birth record to a sex other than the individual’s biological sex. The bill also prohibits a court from ordering a change to an individual’s sex on a birth record to a sex other than the individual’s biological sex. Under the bill, “biological sex” means the biological state of being male or female based on sex chromosomes.
