Legal advocacy is a key component of our work advocating for the Declaration on Women’s Sex-Based Rights in American law and policy. We have written and filed 11 amicus briefs in cases related to the Declaration, bringing a radical feminist legal analysis to courtrooms across the country.

Amicus curiae is Latin for “friend of the court”. An amicus brief is a document submitted to a court by individuals or organizations who have an interest in the case but are not a party in it. Each brief is an opportunity to weigh in on a pending case, offering our unique perspective to judges.

District Courts We’ve Engaged

Timeline

  • October 2021 – US District Court for the Eastern District of Tennessee – Tennessee v. US Dept. of Education
    • We argued that Executive Order 13988 (and subsequent orders and memos) violate the Equal Protection Clause of the 14th Amendment because they violate women’s sex-based right to equal protection of the law.
  • May 2023 – Fourth Circuit – BPJ
    • BPJ is a young man who sued the state to be able to compete on the girls’ team. The federal District Court ruled in favor of the state and WDI USA urged the Fourth Circuit to affirm that decision on appeal.
  • June 2023 – Fifth Circuit – Neese
    • We argued that the government’s policy of prohibiting sex-specific medical care harms women and girls by prioritizing “gender identity” over sex in medical care.
  • July 2023 – Sixth Circuit – Skrmetti
    • At issue was a Tennessee ban on the medicalization of children (often referred to by the euphemism “gender affirming care”).
  • December 2023 – Tenth Circuit – Westenbroek
    • At issue in this case was the ability of women and girls to assemble outside the presence of men (specifically, in the context of a sorority whose bylaws mandate that any new member “shall be a woman”).
  • April 2024 – Ninth Circuit – Olympus Spa
    • At issue in the case was the ability of a female-only nude spa to exclude men. As we say in our brief, “It is truly a testament to where we are as a society today that it must be said in the context of federal civil rights litigation that women don’t have penises.” 
  • August 2024 – Supreme Court – Hecox
    • Idaho enacted a law protecting female-only sports and a man named Lindsay Hecox filed a legal challenge. We urged SCOTUS to take this case.
  • August 2024 – Supreme Court – BPJ
    • We urged SCOTUS to take on this sports case as well.
  • October 2024 – Supreme Court – Skrmetti
    • Our first substantive brief filed before the Supreme Court! We argued that “transgender” has no coherent meaning and is not an immutable trait.
  • August 2025 – Seventh Circuit – Mukwonago
    • In this case, a minor boy was demanding to be able to use the girls’ facilities at his school and at various school-sponsored events. We argued that the school district’s policy in this case is consistent with both Title IX and the Equal Protection Clause.
  • September 2025 – Supreme Court – BPJ and Hecox
    • In a consolidated brief for these two sports cases, we argued that women and girls have the right to be protected as a discrete sex class under both the Equal Protection Clause and Title IX.
