WASHINGTON — Conservatives are praising the Trump administration’s rollback of public school bathroom requirements for transgender students, saying the move corrects a legal overreach by the Obama administration that is best left for states to decide. Transgender rights advocates, meanwhile, are vowing to overcome a major setback.

“We’re not discouraged. And we’re going to keep fighting like we have been and keep fighting for the right thing,” said Gavin Grimm, a transgender teen who sued his Virginia school over its bathroom policy and whose case is set to be heard by the Supreme Court next month.

The Justice and Education departments said Wednesday that public schools no longer need to abide by the Obama-era directive instructing them to allow transgender students to use bathrooms and locker rooms of their chosen gender. That guidance, issued in May, led to a spate of lawsuits over how it should be applied, according to a letter from the departments being sent to schools nationwide.

The agencies said they withdrew the guidance “in order to further and more completely consider the legal issues involved.”

Anti-bullying safeguards for students will not be affected by the change, according to the letter. But advocates of protections for transgender teens said the overall rollback sends “a message that something is wrong with them, which is harmful,” said Nancy Haque, co-executive director of Basic Rights Oregon.

Grimm’s case also could be in jeopardy with the guidance now lifted. The high court could decide not to hear it and direct lower courts to settle that issue instead.

There won’t be any immediate impact on schools, because the Obama guidance had been temporarily blocked since August by a federal judge in Texas, one of 13 states that sued over the directive. And schools remain free to provide the same treatment to students even without guidance.

The earlier guidance was based on the Obama administration’s determination that federal sex discrimination law known as Title IX, applies to gender identity. It will now be up to states and school districts to decide the issue.

The Obama guidance did not sufficiently explain its interpretation of that law, Attorney General Jeff Sessions said in a statement.

A patchwork of state laws could continue to emerge as a result of the change. Fifteen states have explicit protections for transgender students.
