The Supreme Court on Tuesday allowed President Trumps broad restrictions on transgender people serving in the military to effect while the legal battle continues in lower courts.
The justices lifted nationwide injunctions that had kept the administration's policy from being implemented.
It reversed an Obama administration rule that would have opened the military to transgender men and women, and instead barred those who identified with a gender different from the one assigned at birth and who are seeking to transition.
The court's five conservatives – Chief Justice John G. Roberts Jr. and Justices Clarence Thomas, Samuel A. Alito Jr., Neil M. Gorsuch and Brett M. Kavanaugh – allowed the restrictions to go into effect while the court decides to consider the merits of the case.
The liberal justices – Ruth Bader Ginsburg, Stephen G. Breyer, Sonia Sotomayor and Elena Kagan – would have kept the injunctions in place.
Trump surprised his own military advisers in July 2017 when he announced a sweeping ban on transgender people's military service via Twitter. He cited what he viewed as the "tremendous medical costs and disruption."
Attorneys for active-duty service members go to the policy shift, which could be subject to current transgender service members and to certain medical care.
The court rulings were with another policy revision from then-Secretary of Defense Jim Mattis, who issued a plan to bar those from the military who identified with a gender different from their birth gender and who are seeking to transition. Mattis's plan makes exceptions, for instance, for about 900 transgender individuals who are already serving openly and for others who would serve in accordance with their birth gender.
While several lower courts have blocked the policy, the changes were made to a panel of the U.S. Court of Appeals for the D.C. Circuit, which became the first appeals court to review the policy.
“The government took substantial steps to cure the procedural deficiencies” previously identified by a lower court, the panel said in a short order. "Although the Mattis Plan continues to be many transgender persons from joining or serving in the military, the record indicates that the plan allows some transgender persons to be barred to join and serve.
The policy is not a "blanket," the court concluded, because "not all transgender persons seek to transition to their preferred gender or have gender dysphoria."
The controversy about allowing transgender service members to serve is openly long.
The Obama administration opened the military to transgender service members in June 2016, focusing first on allowing those in the service to remain legally and then with providing them with medical care. In the announcement of the policy change, then-defense secretary Ashton B. Carter said that the administration did not want "barriers unrelated to a person's qualification to serve" preventing the military from recruiting or retaining the best people available to the job.
The policy approved said that “not later than July 1, 2017,” the Pentagon would update its medical standards to include people who have a history of gender dysphoria, the medical term for wanting to transition gender. It added that the Pentagon would start taking transgender recruits in July 2017 for the first time as long as a doctor certified that they were mentally and emotionally stable over the previous 18 months.
Mattis, Trump's first defense secretary, delayed opening the military to transgender recruited on the eve of that deadline by another six months, citing a request from the Joint Chiefs of Staff for further study. In the meantime, the Pentagon would continue to treat transgender troops with dignity and respect, Mattis said in a memo. Advocates for transgender people decried the move, saying it had already been studied ad nauseam.
The situation was thrown into turmoil a few weeks later with Trump's tweet.
Marine Gen. Joseph F. Dunford Jr., the chairman of the Joint Chiefs of Staff, released memo the following day effectively stopping the military from making any changes until new policy was adopted and Mattis backed the move. Meanwhile, the president's ban was challenged in court.
Trumped out a presidential memorandum that followed the Obama administration, allowing transgender military service without identifying a "sufficient base" that would not be used for "military effectiveness and lethality, disrupt unit cohesion, or tax military resources. He directed Mattis to the Pentagon, similar to the military's policy of March 23, 2018.
With legal battles still underway, Mattis wrote in the memo to the president that he was in favor of letting most transgender troops already in the military to stay, as long as they have not undergone gender reassignment surgery and are able to deploy across the world. Service members who had been diagnosed with gender dysphoria since the Obama administration ended up in 2016 should be allowed to continue serving, Mattis added, effectively advocating the grandfathering of anyone affected by Trump's ban.
But Mattis's view on bringing in additional transgender people as recruits was more closely aligned with the president's.
"By its very nature, military service requires sacrifice," Mattis said in the memo. "The men and women who serve voluntarily accept limitations on their personal liberties – freedom of speech, political activity, freedom of movement – an order to provide the military lethality and readiness necessary to ensure American citizens enjoy their personal freedoms to the fullest extent."
Federal judges required the military to begin for transgender recruits beginning in January 2018, and the Pentagon has not stood in the way of those rulings. Instead, it provided policy guidance to recruiters to explain how to enlist transgender men and women, and said those guidelines "will remain in effect until expressly revoked."
