The Maine Human Rights Commission has added a seventh school district to its lawsuit challenging policies that prohibit transgender students from playing sports and using facilities that align with their gender identity.

East Grand School in Washington County was named as a defendant this month, according to filings in Kennebec County Superior Court.

In its original lawsuit, the commission argued that the named school districts adopted policies that “create a hostile educational environment for gender non-conforming students” in violation of the Maine Human Rights Act.

In a separate case, the U.S. Department of Justice is suing the state about its policy allowing transgender girls to compete in girls sports. Additionally, a group of Maine Republicans and activists is gathering signatures for a ballot initiative that would change state law to align with the Trump administration’s order.

East Grand, based in Danforth, incorporates Regional School Unit 84 and Maine School Administrative District 14.

According to court filings, the commission was aware of reporting that East Grand’s school board had changed its policy in September but was unable to independently confirm the change and refrained from adding it to the original complaint.

In December, however, the commission discovered social media posts, “which appeared to confirm that East Grand School had not just revoked its policy … but that it had also voted to recognize “only two sexes,” according to the Jan. 9 filing.

The other six districts included in the commission’s suit are MSAD 70 in Hodgdon, Regional School Unit 24 in Sullivan, RSU 73 in Livermore Falls, the Baileyville School District, the Richmond School Department and MSAD 52 in Turner, which was added later.

Officials for the East Grand district could not be reached for comment Friday.

The U.S. Supreme Court recently took up two cases that could have major implications for transgender athletes in scholastic sports. But Kit Thomson Crossman, who directs the commission, said those rulings are unlikely to have any impact on the litigation because they deal with states that have laws prohibiting the participation of transgender women and girls from women’s sports, rather than states like Maine.

The court has not yet ruled on either case.
