The families of two teenage girls are suing California Attorney General Rob Bonta over the state’s laws that allow transgender athletes to compete in girls sports. 

A lawsuit was filed by Ryan Starling, the father of Taylor Starling; Daniel and Cynthia Slavin, the parents to Kaitlyn Slavin; and Save Girls Sports, according to court documents reviewed by Fox News Digital. 

The listed defendants are Bonta and California State Superintendent of Public Instruction Tony Thurmond, along with the Riverside Unified School district and administrators Leann Iacuone and Amanda Chann.

The suit challenges a law in California that allows transgender athletes to compete against girls and women, claiming it is a Title IX violation. 

The law, AB 1266, has been in effect since 2014, giving California students at scholastic and collegiate levels the right to “participate in sex-segregated school programs and activities, including athletic teams and competitions, and use facilities consistent with his or her gender identity, irrespective of the gender listed on the pupil’s records.”

“This law conflicts with federal Title IX protections, which were established to ensure fairness, safety, and equal opportunities for female students and athletes,” a spokesperson for Advocates for Faith & Freedom, the legal firm representing the families, told Fox News Digital in a statement.

“AB 1266 undermines female athletes, forcing them to compete against biological males who hold undeniable physical advantages. This is not equality. This is an assault on fairness and safety.”

The lawsuit, recently amended to include Bonta and Thurmond, was initially filed in November by the Starling and Slavin families. 

It alleges Taylor Starling lost her spot on the varsity cross country team at Martin Luther King High School to a transgender athlete who had just transferred to the school. Starling and Slavin also alleged that when they wore shirts that said “Save Girls Sports” in protest, they were scolded by administrators who compared the shirts to swastikas. 

The plaintiffs are looking to bring statewide change to California. 

“Plaintiffs seek a federal ruling that AB 1266 violates Title IX as well as a decision holding the District accountable for violating their First Amendment rights. They demand injunctive relief to stop schools from forcing biological girls to compete with and against males, a judgment affirming sex-based protections in athletics and compensation for damages caused by these discriminatory policies,” the Advocates for Faith & Freedom spokesperson said.

HOW TRANSGENDERISM IN SPORTS SHIFTED THE 2024 ELECTION AND IGNITED A NATIONAL COUNTERCULTURE

Ryan Starling previously told Fox News Digital the loss of his daughter’s varsity spot disrupted his entire family emotionally, because cross country played a pivotal role in her life. And then when his daughter and other girls on the team confronted their school administrators about it, he claims, they were told “transgenders have more rights than cisgenders.”

“It’s been told multiple times to not just Taylor, but her sister,” Ryan Starling said, adding that Taylor is one of three triplets, and all three are active on varsity sports teams. “All the administrators at Martin Luther King have stated this comment, and the Title IX coordinator for the Riverside Unified School District has stated ‘that as a Cisgender girl, they do not have the same rights as a transgender girl’ to multiple girls, not just our daughters, but multiple girls on campus.” 

An RUSD spokesperson declined to give an official comment on Ryan Starling’s claims in a conversation with Fox News Digital. 

The RUSD previously provided a statement to Fox News Digital insisting that its handling of the situation has been in accordance with California state law. 

“While these rules were not created by RUSD, the district is committed to complying with the law and CIF regulations. California state law prohibits discrimination of students based on gender, gender identity and gender expression and specifically prohibits discrimination on the basis of gender in physical education and athletics. The protections we provide to all students are not only aligned with the law but also with our core values which include equity and well-being,” the statement said. 

Dan Slavin previously told Fox News Digital his family may continue to raise awareness of this issue in the 2026 California gubernatorial election if the issue hasn’t been resolved. 

“If nothing changes here in the next couple of years, it absolutely should be part of the next election,” he said.

“I want to see policies change,” Slavin added. “I keep saying the system is broken, and it’s doing more harm than good. And I want to see people understand that and admit that. Sometimes, we make mistakes, and it’s OK to admit that, but we need to make changes and get out of those mistakes we make.” 

California State Assemblymember Kate Sanchez announced in early January she is introducing a bill to ban transgender athletes from competing in girls and women’s sports.

Sanchez, a Republican, will propose the Protect Girls’ Sports Act to the state legislature. Currently, 25 states have similar laws in effect.
