Gavin Grimm, a young transgender man, has finally put to rest an ongoing lawsuit against his Virginia public school district, reports The New York Times.

After years of fighting an anti-transgender bathroom policy at Gloucester County Public Schools in a legal battle that made it all the way to the federal level, a U.S. district judge ruled that Grimm had indeed been the subject of gender-based discrimination.

"There is no question that the board’s policy discriminates against transgender students on the basis of their gender nonconformity,” Judge Wright Allen wrote in Friday's 28-page ruling. “Transgender students are singled out, subjected to discriminatory treatment, and excluded from spaces where similarly situated students are permitted to go.”

Grimm, now 20, was a student in Gloucester County from 2013 to 2017. His fight to use the bathroom that corresponds with his gender identity became one of the more prominent incidents, if not the most prominent incident, of discrimination against trans teens at schools in the U.S.

He has faced plenty of setbacks along the way, some of which he detailed in a 2017 post-grad essay for NewNowNext.

"Even though I’m graduating without a resolution to my case," Grimm wrote more than two years ago, "I know we’re going to win this fight. I didn’t get a typical high school experience, and I can’t get those years back. But I’m so grateful for all the support I’ve received, and the people I’ve gotten to meet along the way."

More recently, judges in U.S. District Court of the Eastern District of Virginia denied the school district's motion to dismiss the case this May, providing the first clear decision from a federal judge in Grimm's favor.

Gillian Branstetter from the National Center for Transgender Equality described last week's ruling as "very important."

“For many people, in a cultural sense, the Gavin Grimm case is the case, and not merely the case governing the right of transgender students, but the case centering on transgender rights, period,” she told The Times.

Grimm himself expressed his relief at the end of a grueling, highly public era on Twitter:

"I promise to continue to advocate for as long as it takes for everyone to be able to live their authentic lives freely, in public, and without harassment and discrimination," he added.

The Trump administration—and current Education Secretary Betsy DeVos—have pushed back against progress made for LGBTQ students during the Obama era, and Grimm isn't alone in his fight. Young trans people in a number of states, including Indiana, Florida, and Wisconsin, have taken legal action against anti-LGBTQ policies in schools nationwide.
