A divided federal appeals court ruled Monday that the Trump administration cannot remove trans-identified service members from active duty while a legal challenge to the policy moves forward, with the lone dissenting judge warning that the court had seized a role the Supreme Court has never claimed for itself.

The three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit split 2, 1, upholding a lower court's preliminary injunction that shields currently serving trans-identified troops from separation. But the same panel vacated a separate ruling that had blocked the administration from refusing to enlist new trans-identified applicants, a partial win for the government that received far less attention.

The ruling lands at the intersection of military readiness, executive authority, and the growing willingness of federal courts to second-guess decisions that have traditionally belonged to the commander-in-chief and Congress. And the fault lines on the panel track neatly with the presidents who appointed each judge.

The executive order and the Pentagon's follow-through

President Donald Trump signed the executive order on January 27, 2025, one week into his second term. The order, titled "Prioritizing Military Excellence and Readiness," stated plainly that "expressing a false 'gender identity' divergent from an individual's sex cannot satisfy the rigorous standards necessary for military service."

The language left little room for ambiguity. The order described the adoption of a gender identity inconsistent with one's sex as conflicting with "a soldier's commitment to an honorable, truthful, and disciplined lifestyle, even in one's personal life." It added that a man's assertion that he is a woman "is not consistent with the humility and selflessness required of a service member."

The following month, the Department of Defense implemented the directive with a policy of its own: "Service members who have a current diagnosis or history of, or exhibit symptoms consistent with, gender dysphoria will be processed for separation from military service."

A group of currently serving trans-identified service members and prospective enlistees challenged the policy in court, alleging it violated the equal protection component of the Fifth Amendment. The plaintiffs contended the policy "is not based on any legitimate governmental purpose," instead "reflect[ing] animosity toward transgender people because of their transgender status."

A lower court agreed and issued a preliminary injunction. The Trump administration appealed. Monday's ruling was the result.

The majority opinion: 'arbitrary and based upon animus'

Judge Robert Wilkins, an Obama appointee, authored the majority opinion. Judge Judith Rogers, a Clinton appointee, joined him. Their conclusion was blunt. Wilkins wrote that "the Hegseth Policy is both arbitrary and based upon animus, and for those reasons the Policy violates Plaintiff-Appellees' constitutional right to equal protection of the law."

Wilkins pointed to the service records of the plaintiffs still in uniform. As he put it:

"Appellants have not contested that all of the currently serving Plaintiff-Appellees, who dedicated a combined 130 years to military service and collectively earned more than 80 commendations, have served honorably and met all military standards during their service. Appellants have thus forfeited any argument that, for purposes of the balance of equities analysis, retaining these servicemembers will harm national security."

That framing placed the burden squarely on the administration, and then declared the administration had failed to carry it. Wilkins wrote separately that "Appellants have not shown how a preliminary injunction preventing them from removing current servicemembers will harm national security."

The pattern is now familiar across multiple policy fronts. Federal judges, often appointed by Democratic presidents, have blocked Trump administration initiatives on procedural or constitutional grounds, frequently using language that goes well beyond the narrow question before the court.

Yet the majority did draw one line the plaintiffs will not like. On the question of prospective service members, people who want to join the military but have not yet enlisted, Wilkins vacated the lower court's ruling in their favor. He wrote that "the harms and equities of their situations are not identical to those of persons already serving" and that those plaintiffs "can still obtain full relief later, following a final adjudication on the merits."

In other words, the court protected those already in uniform but declined to force the military to open its doors to new trans-identified recruits while the case plays out.

Walker's dissent: courts claiming a role they've never held

The sharpest language in Monday's opinion came not from the majority but from the dissent. Judge Justin Walker, a Trump appointee, accused his colleagues of breaking with decades of judicial restraint on military matters.

Walker invoked what he called "the longstanding tradition of deference to military decisionmaking" and laid out the constitutional stakes in stark terms:

"The military is a distinct constitutional system, separate from civilian society. Its rules are necessarily different than those of civilian society. courts do not apply the same standards to military rules as they do to the rules of civilian society."

Then Walker delivered his most pointed rebuke:

"Only the Executive and Congress are responsible for system-wide military judgments about the composition of the armed forces. The Supreme Court has never assumed that role for itself. Neither has the D.C. Circuit. Not until today."

Walker's dissent echoes a frustration shared by many conservatives who have watched the judiciary expand its reach into domains traditionally reserved for the political branches. Whether the subject is military composition, immigration enforcement, or public health policy, the pattern repeats: an executive action, a lower-court injunction, and an appellate panel that divides along the lines of which president put each judge on the bench.

The growing tension between the judiciary and the executive branch has prompted calls from some lawmakers for accountability. Sen. Eric Schmitt, for instance, has demanded the House impeach a federal judge over a separate controversial ruling, a sign of how deep the frustration runs on the right.

What the ruling does, and doesn't, settle

Monday's decision is a preliminary injunction ruling, not a final judgment on the merits. The policy's constitutionality has not been definitively resolved. The case will continue in the lower court, and the administration retains the option of seeking Supreme Court review.

For now, the practical effect is limited but real: trans-identified service members currently on active duty cannot be separated under the policy while litigation proceeds. The administration can still decline to enlist new trans-identified applicants.

The 2, 1 split matters. It signals that the question is genuinely contested among federal judges, not a matter of settled law. And it all but guarantees that the Supreme Court will eventually face the issue, a court that, unlike the D.C. Circuit panel, is not stacked with appointees from one political era.

Broader questions about the judiciary's role in military affairs continue to surface in other contexts as well. A recent ruling blocking West Point from enforcing speech restrictions on civilian faculty raised similar concerns about where judicial authority ends and military discretion begins.

The deeper question

The executive order's language was not clinical. It made a substantive argument about military culture, discipline, and the nature of truth. Whether one agrees with that argument or not, it reflected a policy judgment made by the elected commander-in-chief and implemented by the Department of Defense.

The majority treated that judgment as constitutionally suspect, driven by animus rather than legitimate military purpose. The dissent treated it as exactly the kind of decision courts have historically refused to override.

Both sides cited precedent. Both sides invoked the Constitution. But only one side can be right about where the line falls between judicial review and judicial overreach.

The administration has also faced scrutiny abroad on questions of faith and government authority. The Trump administration has been monitoring the UK prosecution of a pastor charged for preaching near a hospital, a reminder that conflicts between government power and individual conviction extend far beyond the military context.

Meanwhile, courts across the country continue to shape the boundaries of executive authority in ways that would have been difficult to imagine a generation ago. An Alabama Supreme Court ruling expanding police authority to demand physical identification illustrates how varied, and how consequential, judicial decisions on government power have become.

Judge Walker framed Monday's ruling as a first. If he is right that the D.C. Circuit has never before claimed the power to dictate the composition of the armed forces, then the question is not whether the policy is wise. The question is whether two judges appointed by Democratic presidents should hold veto power over the military decisions of an elected president, and whether the Supreme Court will let that stand.

When courts start telling the commander-in-chief who must serve in uniform, they are no longer checking executive power. They are exercising it.
