Florida’s state athletic board fined a high school and put it on probation Tuesday after a transgender student played on the girls volleyball team, a violation of a controversial law enacted by Gov. Ron DeSantis and the Legislature.

The Florida High School Athletic Association fined Monarch High $16,500, ordered the principal and athletic director to attend rules seminars and placed the suburban Fort Lauderdale school on probation for 11 months, meaning further violations could lead to increased punishments. The association also barred the girl from participating in boys sports for 11 months.

The 2021 law, which supporters named “The Fairness in Women’s Sports Act,” bars transgender girls and women from playing on public school teams intended for student athletes identified as girls at birth.

The student, a 10th grader who played in 33 matches over the last two seasons, was removed from the team last month after the Broward County School District was notified by an anonymous tipster about her participation. Her removal led hundreds of Monarch students to walk out of class two weeks ago in protest.
