A bathroom bill is the common name for legislation or a statute that defines access to public facilities – specifically restrooms – by transgender individuals. Bathroom bills affect access to sex-segregated public facilities for an individual based on a determination of their sex as defined in some specific way – such as their sex as assigned at birth, their sex as listed on their birth certificate, or the sex that corresponds to their gender identity. A bathroom bill can either be inclusive or exclusive of transgender individuals, depending on the aforementioned definition of their sex.
Critics of bills which exclude transgender individuals from restrooms which conform to their gender identity argue that they do not make public restrooms any safer for cisgender (non-transgender) people, and that they make public restrooms less safe for both transgender people and gender non-conforming cisgender people. Additionally, critics claim there have been no documented cases of a transgender person attacking a cisgender person in a public restroom, while many transgender people have been verbally, physically, and sexually harassed or attacked by cisgender people in public facilities.
One bathroom bill, the Public Facilities Privacy & Security Act in North Carolina, has been approved as a law, although a preliminary injunction has been issued to prevent enforcement of its restroom-related provisions by the University of North Carolina.
In Canada, the New Democratic Party (NDP) has introduced several bills that tried to include gender identity and gender expression among the characteristics protected from discrimination and eligible to be considered in sentencing crimes motivated by hate. These bills were frequently referred to as "bathroom bills" by their critics as they would have allowed transgender individuals to use the public facilities corresponding to their gender identity.
