On October 14, 2021, GLAD filed a friend-of-the-court (amicus) brief along with the National Center for Transgender Equality and the National Center for LGBTQ Rights.

The plaintiffs in Soule et al v. CT Association of Schools et al, three high school students – two of whom have since graduated – sought a judicial order that no transgender girls or young women may participate in school sports. This would effectively ban trans girls from school sports. GLAD’s briefs urges the court to affirm the lower court’s dismissal.
