A Plano teacher, a Houston high schooler, the Texas teachers’ union and a network of LGBTQ clubs filed a federal lawsuit in August to block parts of a new Texas law that bans certain student groups from public schools.

The law, which took effect Sept. 1, bars schools from sponsoring a “student club based on sexual orientation or gender identity.” It also forbids schools from providing instruction, guidance or programming on sexual orientation or gender identity. Schools are barred from helping in the social transitioning of a transgender child, which can include using new names or pronouns.

A former faculty sponsor for a Gender and Sexuality Alliance in Plano ISD; a Houston high schooler; the Gender and Sexuality Alliances Network, a nonprofit that represents GSA clubs in Texas schools; and advocacy group Students Engaged in Advancing Texas say their freedom of speech and expressive association “will be irreparably suppressed” under the new law.

Texas AFT, the teachers’ union, joined the lawsuit as a plaintiff Sept. 15.

“S.B. 12 is one of the most extreme education censorship laws in the country, undermining the free speech rights of Texas students, parents, and educators,” said Brian Klosterboer, senior staff attorney at the ACLU of Texas, who filed the suitin the U.S. District Court for the Southern District of Texas.“We’re challenging this law in court because our schools should be places of truth, inclusion, and opportunity — not fear and erasure.”

The lawsuit names Texas Education Commissioner Mike Morath as a defendant, as well as Plano, Katy and Houston ISDs.

“Plano ISD is obligated to comply with the law as written unless or until the courts provide further direction,” said Zoheb Hassanali, the district’s assistant director of communications, public relations and social media.

He said district staff have received training to ensure compliance with the law.

“Our focus continues to be on educating and supporting our students, and we will not allow external litigation to distract us from that responsibility,” he added.

Houston ISD’s press office said the district does not comment on pending litigation.

Representatives from Katy ISD and the Texas Education Agency did not respond to emailed requests for comment.

The legal action comes as school districts across Texas are adopting policies to comply with the state law, which prohibits diversity, equity and inclusion efforts in K-12 schools.

Rep. Jeff Leach, R-Allen, who introduced the legislation, said it ensures parents are at the “head of the table when it comes to their kids’ education.”

In addition to the ban on LGBTQ clubs, the legislation requires schools to get a parent’s permission before a child can join any school club.

“Our schools should be about teaching history and reading, writing and math and civic responsibility,” Leach said as he advocated for the bill in the Legislature. “We need to get away from some of the more toxic social issues.”

If the law is not blocked, all 22 student-run Gender and Sexuality Alliance clubs registered with the GSA Network will likely shut down, according to the filing.

Leach criticized the organizations during legislative discussions, calling them “school-sponsored and school-sanctioned sex clubs.” Supporters and members of the clubs say they provide safe and welcoming spaces for students.

The groups in the lawsuit say the ban “ostracizes” students “who have a sexual orientation or gender identity that differs from other students.” It also “harms allies of LGBTQ+ students who seek to learn about issues impacting their friends and advocate for a safer and more inclusive school environment,” according to the filing.

At least one Gender and Sexuality Alliance in Plano ISD disbanded ahead of the law’s implementation date, according to court documents. Students tried to start a new club, but school administrators said it would not be allowed.

One student decided to be homeschooled because the club shut down “and the fact that their affirming name and pronouns will no longer be respected by teachers and staff,” court documents read.

The law has created “a climate of fear and discrimination” in the Plano ISD school, “where the voices of LGBTQ+ students and educators are suppressed.” The school is not identified in the lawsuit, and the teacher and student plaintiffs go by pseudonyms to protect them from retaliation.

The Plano ISD teacher, who was also the faculty sponsor of the now-disbanded Gender and Sexuality Alliance, said the law’s “vague and broad” requirements create “a massive gray area about how and whether she can support her transgender students.”

Texas AFT, the teachers’ union, said it has already received a “high volume of inquiries” from members on its grievance hotline about what the law means, its “harsh professional consequences and the harm it is causing their relationships with their students and concerned parents.”

For a Houston high schooler at Kinder High School for the Performing and Visual Arts, the law could mean she can’t join or start a Gender and Sexuality Alliance at her new school.

The high schooler participated in GSA in middle school, where she “found community and support in her own experience of coming out as an LGBTQ+ student and felt safer and happier,” the filing reads.

Under the law, she worries she won’t have that same experience. She already feels the law “is suppressing her ability to speak with teachers” about certain topics, including social transitioning.
