Why It Matters
A federal judge is examining how Idaho’s new transgender bathroom law will work in practice before deciding whether to block it from taking effect. The law, set to take force on July 1, could expose Idahoans to criminal penalties — including felony charges — for entering restrooms designated for the opposite biological sex. The case has drawn national attention as one of the most far-reaching bathroom restrictions in the country.
What Happened
Chief U.S. District Judge Amanda K. Brailsford heard arguments over Idaho House Bill 752, which passed the Legislature on a party-line Republican vote. Six transgender Idahoans filed suit challenging the measure, asking the court to grant class-action protections for those who use facilities aligned with their gender identity. Plaintiffs are not contesting the law’s restrictions on changing rooms — only the bathroom provisions.
Judge Brailsford pressed attorneys from both sides on the mechanics of enforcement, signaling close scrutiny of how the measure would function once active. She said she would issue a ruling on the preliminary injunction request quickly.
What the Law Does
HB 752 makes it a criminal offense to “knowingly and willfully” enter a bathroom or changing facility designated for the opposite sex. A first offense is a misdemeanor. Repeat violations carry felony penalties of up to five years in prison, among the steepest consequences for such a law in any state.
The American Civil Liberties Union, which is involved in the legal challenge, says Idaho’s law is the only bathroom ban in the country that extends to private businesses. Three states now have criminal bathroom restrictions, but Idaho’s penalties are the most severe of the three.
Competing Arguments
Lambda Legal attorney Kell Olson argued the law creates immediate danger for transgender residents regardless of how they respond to it. “HB 752 does make Idaho less safe for transgender people,” Olson said. “It threatens serious and immediate harm, no matter what trans people do.”
Idaho Solicitor General Michael Zarian offered a different framing on behalf of the state, arguing the concern is not about the behavior of transgender individuals specifically but about broader safety in sex-separated spaces. “The point is not that transgender people are more likely to commit safety violations,” Zarian said. “The point is that men in women’s restrooms are more likely to commit safety violations.”
A 2025 study from the UCLA Williams Institute found no evidence that harm to others increases when transgender people use facilities consistent with their gender identity. The same research found that transgender individuals report higher rates of verbal harassment and physical assault when denied access to facilities aligned with their identity.
By the Numbers
- Up to 5 years in prison for repeat violations under HB 752
- 6 transgender Idahoans named as plaintiffs in the lawsuit
- 3 states currently have criminal bathroom bans; Idaho’s penalties are the highest
- Idaho’s 2023 public school bathroom ban took full effect last month
- Most plaintiffs hold state-issued ID cards aligned with their gender identity
Zoom Out
Idaho has been at the center of a series of legal battles over policies affecting transgender residents. The state’s 2020 ban on transgender women and girls competing in sports aligned with gender identity remains tied up pending a U.S. Supreme Court ruling. The 2023 school bathroom ban for public schools only recently took full effect after a separate legal challenge was dropped when a transgender student involved in that suit died by suicide.
The human cost of the ongoing legal uncertainty was also raised in court. At least one plaintiff and a Boise family of medical professionals indicated they are considering leaving Idaho over the law’s potential impact. Idaho lawmakers have continued advancing legislation in this space — a pattern also reflected in other areas where the Legislature moved on ballot and policy questions during the 2026 session. The Legislative Council recently set ballot language for marijuana and English-language amendments, also over Democratic objections, underscoring the Legislature’s conservative direction this term.
What’s Next
Judge Brailsford said she intends to rule on the preliminary injunction request before July 1, when HB 752 is scheduled to take effect. Her decision will determine whether the law can be enforced while the underlying lawsuit proceeds. If she denies the injunction, the law will activate as planned and enforcement questions raised during the hearing will move from theoretical to immediate.
