Texas Attorney General Ken Paxton has sued the city of Denton, accusing it of breaking the Texas Women’s Privacy Act by allowing organizers of an LGBTQ-themed swimming event to offer “gender-neutral changing rooms” at a city-owned facility.

The lawsuit, filed Wednesday in Denton County district court, seeks a temporary restraining order and permanent injunction against the city and several officials, including Mayor Gerard Hudspeth. It targets the planned June 7 “Big Gay Swim Day” at the Quakertown Civic Center Pool, organized by the nonprofit groups PRIDENTON and OUTreach Denton.

The Texas Women’s Privacy Act, enacted in 2025, requires publicly owned multi-occupancy changing rooms, locker rooms, and similar facilities to be designated by biological sex. Paxton’s office argues the city has only two such changing rooms — one for men and one for women, and that event organizers intend to open them to both sexes, in direct violation of the law.

The attorney general’s complaint states the city failed to take “every reasonable step” to prevent the violation after receiving a formal complaint from a resident. Court filings include the city’s response, which described the event as a private rental and said official signage must remain in place.

PRIDENTON and OUTreach Denton criticized the lawsuit as “frivolous” and “a waste of taxpayers’ time and money,” calling it an attack on their fourth annual Pride Month swim party. The groups are not named as defendants in the suit.

This case is among the first significant legal challenges to the Texas Women’s Privacy Act. The city had not yet filed a formal response as of Thursday.
