Idaho has found itself at the center of a heated debate over a new law that restricts transgender individuals from using public bathrooms and changing facilities that align with their gender identity. The law, set to take effect on July 1, 2026, has sparked a legal battle and raised questions about enforcement and civil rights.
The controversy began when Idaho officials suggested using DNA testing to enforce the law, a proposal that has drawn criticism from civil rights groups and legal experts. The debate highlights the broader implications of the law and its potential impact on transgender individuals in Idaho.
Understanding House Bill 752
House Bill 752also known as the transgender bathroom ban, mandates that individuals use public bathrooms and changing facilities corresponding to the sex they were assigned at birth. The law imposes criminal charges for those who “knowingly and willfully” violate this rule, with repeat offenders facing up to five years in prison.
During a Federal Court hearing on June 5, 2026, US District Judge Amanda Brailsford questioned how the state planned to enforce the law, particularly given that many transgender individuals now carry ID cards that reflect their correct gender. Idaho Solicitor General Michael Zarian responded by suggesting that DNA testing could be used to determine an individual’s biological sex.
The Legal Challenges and Concerns
The lawsuit challenging the law was brought by six transgender Idahoans, represented by Lambda Legal attorney Kell Olson. Olson argued that the law poses serious risks to transgender individuals, making them vulnerable to harassment and assault. “HB 752 does make Idaho less safe for transgender people. It threatens serious and immediate harm, no matter what trans people do,” Olson stated.
ACLU of Idaho attorney Emily Croston also raised concerns about the practicality of enforcing the law. “I don’t think the state has an answer for how you identify someone’s biological sex,” Croston said. “Are we just going to look at folks as they enter a restroom and determine whether we think they look enough like a man or a woman? That’s ridiculous.”
The Enforcement Dilemma
The debate over enforcement has highlighted the challenges law enforcement officers would face in determining an individual’s biological sex. Idaho Solicitor General Michael Zarian suggested that DNA testing could be a solution, although he acknowledged that such testing would not likely be conducted on the spot. Olson countered that DNA testing typically requires a warrant, making the proposal impractical.
Law enforcement groups have also expressed concerns about the law’s enforceability. The Idaho Fraternal Order of Police noted that officers would be placed in difficult positions, having to determine an individual’s biological sex in order to enforce the statute. “In many circumstances, there is no clear or reasonable way for officers to make that determination without engaging in questioning or investigative actions that could be viewed as invasive and inappropriate,” the group stated.
The Broader Impact
The transgender bathroom ban is part of a series of anti-trans laws passed by the Idaho Legislature in recent years. These laws have drawn criticism from civil rights groups and have led some transgender individuals to consider leaving the state. Diego Fable, a transgender man and part of the lawsuit, expressed his intention to move out of Idaho, citing the state’s increasingly hostile environment for transgender individuals.
A 2026 study by the UCLA’s School of Law’s Williams Institute found no evidence that people face more harm if transgender individuals are allowed to use bathrooms that align with their gender identity. However, the study did find that transgender individuals who are refused access to facilities that align with their gender identity report higher rates of verbal harassment and physical assault.
The legal battle over Idaho’s transgender bathroom ban continues, with Chief U.S. District Judge Amanda K. Brailsford expected to issue a ruling on whether to grant a preliminary injunction that could block the law throughout the lawsuit. The outcome of this case will have significant implications for transgender rights and the broader debate over bathroom access laws.
