Six Idaho residents have filed a federal lawsuit challenging the constitutionality of the state’s newly enacted bathroom access law, which establishes criminal penalties for individuals who enter restrooms designated for the opposite sex.

The complaint, filed in federal court Thursday, takes aim at House Bill 752, legislation that passed the Idaho Legislature in March and received Governor Brad Little’s signature on April 1. The law is scheduled to take effect on July 1.

Under the provisions of HB 752, individuals who “knowingly and willfully” enter a restroom or changing room designated for the opposite sex would face misdemeanor charges. The plaintiffs argue this measure is unconstitutional, discriminatory, and lacks sufficient clarity for proper enforcement.

The lawsuit contends that the law would expose transgender Idaho residents to violence, harassment, and psychological harm while potentially subjecting them to criminal prosecution for using public restrooms that correspond with their gender identity rather than their biological sex.

Diego Fable, one of the six plaintiffs named in the suit, articulated the practical concerns facing those who would be affected by the law’s implementation. Fable stated that the legislation would compel a return to using facilities designated for biological sex, a change that would invite unwanted attention and scrutiny. The plaintiff suggested that compliance with the law would leave only two realistic options: remaining at home or departing Idaho entirely, thereby severing ties with established community connections.

This legal challenge arrives as the nation’s highest court weighs separate but related questions regarding state restrictions on transgender participation in women’s athletic competitions. The Supreme Court’s consideration of those cases underscores the broader national debate over how states may regulate access to sex-segregated spaces and activities.

Idaho has positioned itself at the forefront of states enacting legislation in this area, with state officials defending such measures as necessary protections for privacy and safety in intimate facilities. The legal arguments presented in this case will test whether states possess the constitutional authority to enforce such restrictions or whether they impermissibly infringe upon the rights of transgender individuals.

The federal court will now be tasked with examining whether HB 752 passes constitutional muster. The plaintiffs bear the burden of demonstrating that the law violates their constitutional rights, while the state will defend its authority to establish such regulations within its borders.

As this case proceeds through the federal judiciary, it represents yet another chapter in the ongoing legal and cultural debate over how American society balances competing claims of rights, privacy, and safety in spaces traditionally segregated by biological sex. The outcome will have implications not only for Idaho but potentially for similar legislative efforts in other states across the nation.

The court has not yet set a timeline for proceedings in this matter.
