Nearly a year and a half after President Trump first announced his plan to ban transgender people from serving in the military, the U.S. Supreme Court has given the go-ahead for the administration to carry out its plan. According to a report from Time, the ruling—decided Tuesday, January 22—has “cleared the way” for the implementation of the ban. Although there have been several injunctions against the policy from lower circuit courts, the new ruling now allows the policy to be implemented despite the fact there are cases still in litigation. Some see the ruling as a way for the Supreme Court to remain hands-off when it comes to policy decisions made by the commander in chief.

“Under Article II of the U.S. Constitution, President Trump has every right to review and change his predecessor’s policies affecting military personnel who identify as transgender or suffer from gender dysphoria,” wrote Elaine Donnelly, president of the Center for Military Readiness. “Four federal district judges have tried to usurp presidential power, ordering the Trump administration to continue Obama-era policies.”

The ban has been controversial since its announcement. Supporters of the ban and the president see the ruling as a clear win, while people on the other side of the debate have already vowed to fight back. One tweet from California Democratic Senator Kamala Harris read, “Transgender military members have the courage to serve our country and deserve to do so. We have to fight back to reverse this.” Other prominent Democratic legislators, such as House Speaker Nancy Pelosi, echoed Harris’ remarks.

“As always, we treat all transgender persons with respect and dignity,” said Department of Defense (DoD) spokeswoman Lt. Col. Carla M. Gleason in a statement, according to NBC. “DoD’s proposed policy is NOT a ban on service by transgender persons. It is critical that DoD be permitted to implement personnel policies that it determines are necessary to ensure the most lethal and combat effective fighting force in the world.”
