U.S. Supreme Court has cleared the way for former President Donald Trump to begin enforcing a controversial ban on transgender individuals serving in the military. The decision, handed down Tuesday, allows the policy to take effect immediately—even as legal battles over its constitutionality continue in lower courts.
The brief, unsigned ruling didn’t provide any explanation, which is standard practice for emergency applications. But its impact is significant: it lifts a nationwide injunction that had temporarily blocked the policy, meaning thousands of currently serving transgender troops could now face discharge.
Roughly 4,200 service members—about 0.2% of the military—identify as transgender, according to Defense Department estimates. These individuals, many of whom have served with distinction, are now in limbo as the administration pushes forward with a policy critics call discriminatory and baseless.
The ban stems from an executive order signed on the very first day of Trump’s second term, overturning one issued by President Joe Biden that had allowed transgender people to serve openly. Trump followed up with a second order just days later, declaring that adopting a gender identity different from one’s sex at birth “conflicts with a soldier’s commitment to an honorable, truthful and disciplined lifestyle.”
The Defense Department quickly moved to implement the directive in February, announcing that transgender individuals would be forced out of the military. While the administration argues the ban is necessary to preserve discipline and unit cohesion, opponents say there’s no evidence to support that claim.
One such opponent is Navy Commander Emily Shilling, a decorated aviator with 19 years of service and more than 60 combat missions under her belt. Shilling, who began her transition in 2021, is one of several plaintiffs challenging the ban. A federal judge in Washington state, Benjamin H. Settle, used her case to highlight the policy’s flaws.
“There is no claim and no evidence that she is now, or ever was, a detriment to her unit’s cohesion,” Settle wrote in a March ruling. He called the government’s arguments “illogical” and said banning Shilling based solely on her gender identity was unjustifiable. His ruling blocked the ban nationwide—until the Supreme Court stepped in.
Civil rights groups like Lambda Legal and the Human Rights Campaign Foundation condemned the Court’s decision. “Today’s ruling is a devastating blow to transgender service members who have proven their dedication and ability,” the organizations said in a joint statement.
The case is part of a broader push by the Trump administration to roll back protections for transgender Americans. In addition to targeting service members, the administration has attempted to restrict access to bathrooms, limit participation in sports, and ban gender-affirming care for minors. The Supreme Court is expected to rule soon on a related case involving Tennessee’s ban on medical transition treatment for people under 19.
Trump’s current policy mirrors a similar ban he announced during his first term via Twitter, which was initially blocked by the courts but eventually allowed to proceed in 2019. That earlier version made exceptions for some already-serving transgender troops. The new order, critics argue, is far more sweeping and hostile in tone—suggesting transgender people are “inherently untruthful” and “incapable” of military service.
For now, the fate of thousands of transgender service members—and those hoping to enlist—hangs in the balance as court battles continue.
