The state of California hurled a pre-enforcement lawsuit at the Trump administration on Monday, saying it would not bow to “illegal” demands that it bar transgender youth from competing in local sports after the U.S. Justice Department tried ordering it to do so last week.

In addition to the lawsuit, the California Department of Education also sent a letter to federal authorities Monday, letting them know that California’s school districts were not obligated to provide certifications to the DOJ on its transgender sports enforcement, and that doing so would violate not only existing state law “but also the U.S. Constitution,” according to a press release from the state’s attorney general.

“Defendants have no right to make such a demand,” the state’s complaint says. “They cite no authority which would allow them to issue or enforce the Certification Demand Letter against California’s LEAs [local educational agencies], nor do they provide any support for their claim.”

California is seeking declaratory and injunctive relief “in anticipation of imminent legal retaliation against California’s school systems” for the state’s refusal to comply, according to officials. They argue that allowing athletic participation consistent with students’ gender identity is “substantially related to the important government interests of affording all students the benefits of an inclusive school environment” — including participation in sports — and preventing the “serious harms that transgender students would suffer from a discriminatory, exclusionary policy.”

The complaint alleges that throughout his presidential campaign for the 2024 election and since taking office, President Donald Trump and his administration have “consistently expressed contempt and animosity” for transgender people as a group.

“Defendants’ statements and actions, as well as those of President Trump, create a distorted narrative that dehumanizes transgender children and pits them against cisgender students,” the complaint charges. “This narrative instigates antagonism and discrimination towards a discrete and insular class of children and demands that LEAs violate the equal protection rights of transgender students by categorically excluding them from school athletics programs that align with their gender identity.”

California officials say Trump’s executive orders and statements over the past few months and years demonstrate an “unapologetic animus” toward transgender people that has “permeated the entire administration, including but not limited to U.S. DOJ,” according to the state’s press release. Attorney General Bonta ripped Trump in an accompanying statement Monday, saying California would not “break the law and violate the Constitution” just to appease the president.
