The proposed bill, SB1628, aims to amend Arizona law by replacing the term "gender" with "sex" in all relevant statutes, rules, and policies, thereby establishing a clear distinction between the two. It mandates that any policy or law prohibiting sex discrimination must ensure that both males and females are treated fairly in comparison to similarly situated individuals of the opposite sex. Additionally, the bill introduces specific definitions for terms such as "boy," "girl," "man," "woman," "mother," and "father," and clarifies that "sex" refers strictly to biological sex at birth, excluding gender identity.

Furthermore, the bill allows for the creation of single-sex environments in various contexts, such as athletics and shelters, when the sexes are not similarly situated. It also requires entities that collect vital statistics to categorize individuals strictly as male or female, while ensuring that this does not mandate the collection of sex data unless legally required. The overarching goal of the legislation is to provide clarity and uniformity regarding sexual discrimination and the rights of individuals based on their biological sex, and it is officially titled the "Arizona Women's Bill of Rights."
