UTAH (ABC4) – The families of two Utah high school students have filed lawsuits against House Bill 11, which prohibits transgender girls from competing in school sports.

The law bans transgender girls from participating in high school girl sports teams regardless of their “medical care or individual circumstances.”

The announcement, which was made by the National Center for Lesbian Rights, said the families are represented by the ACLU of Utah, the National Center for Lesbian Rights, and the firm Wilson Sonsini Goodrich and Rosati.

The families have elected to proceed anonymously to protect the identities of the girls involved. One girl is a 16-year-old junior in high school who wants to play volleyball and a 13-year-old girl who wants to swim.

“This law bans transgender girls from competing with other girls in every sport, at every grade level, and regardless of each girl’s individual circumstances,” said Justice Christine Durham, former Chief Justice of the Utah Supreme Court and senior of counsel at Wilson Sonsini. “It cannot survive constitutional scrutiny and it endangers transgender children.”

By singling out transgender girls for disfavored treatment, the children and their families allege HB 11 violates multiple provisions of the Utah Constitution.

In March, the Utah legislature voted to override Governor Cox’s veto on House Bill 11.

The bill’s sponsor, Rep. Kera Birkeland released the following statement on the lawsuit:

“The lawsuit filed today is not surprising, as such actions have been threatened since the beginning. My goal has always been to protect girls sports and female athletes across the state and I hope the courts will recognize that and uphold the legislation.”

Utah senators Sen. Curt Bramble and Sen. Dan McCay issued the following statements regarding the lawsuit against the bill

“All kids deserve fair opportunities; however, we must acknowledge the fact that biological boys and girls are built differently,” said Sen. Curt Bramble. “H.B. 11 doesn’t prevent athletes from competing as they can still compete against their same biological gender. The intention of H.B. 11 is to preserve women’s sports and protect future athletic opportunities. If a court allows biological males to compete in female sports, H.B. 11 puts Utah ahead of the curve by creating an unbiased, data-driven commission, continuing to protect female athletes.”

“H.B. 11 is trying to protect two things: safety and the integrity of competition,” said Sen. Dan McCay. “It is our responsibility as lawmakers to pass legislation that ensures women still have a place in their sport. H.B. 11 does just that. At times, litigation is part of the process, and we will work within the legal system to get answers. H.B. 11 also creates a commission if a ban is put on hold that will help foster a safe and fair environment for all athletes.”
