A tentative agreement brokered Friday to allow a transgender girl from Plymouth to temporarily coach on the girls’ soccer team has fallen through, two people familiar with the situation say.

Instead, a hearing in federal court in Concord at 2 p.m. will decide whether Parker Tirrell – plaintiff in a lawsuit against New Hampshire’s recent law banning transgender girls from playing on female sports teams – can practice with her team starting tomorrow.

Tirrell, 15, and Iris Turmelle, 14, of Pembroke, along with their families, sued their school districts and the state education commissioner on Friday, claiming the ban, which went into effect Sunday, violates their rights under Title IX and the 14th Amendment to the Constitution.

The contested transgender sports ban was signed into law by Gov. Chris Sununu on July 19. It prohibits students assigned male at birth from participating on girls’ sports teams in grades 5 through 12.

A court transcript shows that at a court hearing Friday, the parties in the case agreed to file an agreement by Monday morning that would allow the girls to participate in school sports and protect the school districts from liability while an initial motion is heard.

But late Sunday afternoon, two people familiar with the case who spoke on background about the details of the litigation said the agreed-upon settlement would not be filed.

“There will be no such agreement,” said one of them.

Neither person would explain what had happened over the past two days that led to the change in the plan, which was set during an online court conference on Friday.

The first football practice for Tirrell, a rising sophomore at Plymouth Regional High School, is at 6 p.m. Monday. Turmelle, a rising freshman at Pembroke Academy, plans to play sports in the winter and spring, the lawsuit says.

Tirrell was notified by the Pemi-Baker Regional School District on Thursday that she would not be allowed to attend Plymouth High School’s football practice on Monday under the new law. Pembroke Academy notified Turmelle on Friday that she would not be able to participate on girls’ sports teams.

In 2019, Turmelle’s birth certificate was updated to show her gender as female, but that didn’t help the family. The law requires the birth certificate to reflect the student’s biological sex “at or near the time of birth.” Tirrell also wants to have her gender changed to female on her birth certificate.

The hearing on Monday will take place in U.S. District Court in Concord before Chief Judge Landya McCafferty.
