This bill proposes significant updates to current statutes regarding sex-based terms and discrimination. It introduces new definitions for terms such as "boy," "girl," "male," "female," "man," "woman," "father," and "mother," clarifying their meanings in legal contexts. The bill mandates that any policy, program, rule, or law prohibiting sex discrimination must ensure that females and males are treated fairly in comparison to similarly situated individuals of the opposite sex. Additionally, it allows for the establishment of separate single-sex environments in specific contexts, such as athletics and facilities, when the sexes are not similarly situated, particularly concerning biological differences.

Furthermore, the bill requires that any entity collecting vital statistics related to sex must categorize individuals as either male or female, while also allowing for the collection of additional data points beyond biological sex. It emphasizes that the term "sex" refers strictly to biological sex at birth and does not encompass gender identity. The legislation aims to provide clarity and uniformity in the state's approach to sexual discrimination and equality, and it includes a severability clause to ensure that if any part of the act is deemed invalid, the remaining provisions will still be enforceable. The act will be known as the "Arizona Sex-based Terms Act."
