The Trump administration is asking the Supreme Court to lift a lower-court order blocking the Bureau of Prisons from restricting sex-trait-modification surgeries, hormones, and social accommodations for federal inmates, a fight that pits security and evidence against activist medicine standards the bureau now calls unreliable.
Solicitor General D. John Sauer went to the high court Monday seeking to free the Bureau of Prisons from an injunction that has kept the agency locked into contested “gender-affirming” practices. The Court of Appeals for the Washington, D.C., Circuit left that injunction in place on Sept. 18. Sauer’s brief lays out why the bureau concluded those interventions no longer qualify as justified treatment for gender dysphoria.
The case is Kingdom v. Trump. Three anonymous inmates, represented by the American Civil Liberties Union Foundation of Washington, D.C., and the Transgender Law Center, sued last year. They claim the new policy violates the Eighth Amendment’s ban on cruel and unusual punishment, equal protection under the Fifth Amendment, the Rehabilitation Act, and the Administrative Procedure Act.
The Daily Signal reported that the bureau’s shift rests on an exhaustive review, a 3,200-page administrative record explained in a 43-page memorandum, and that officials say the policy was adopted independent of any executive order.
Sauer’s filing quotes the bureau’s core finding in plain terms. “BOP determined that sex-trait-modification surgeries, hormone interventions in general, and social accommodations could no longer be justified as treatment for gender dysphoria,” the brief states.
The memorandum goes further on the group the Obama administration once treated as the gold standard. It says the World Professional Association for Transgender Health “openly engages in ideologically based political advocacy, systematically misrepresents evidence, and often bases its recommendations, no matter how impactful for the patient, on low-quality supporting evidence.”
That is a sharp break from the prior approach. The Obama-era Bureau of Prisons relied on WPATH authority to approve sex-rejecting procedures for inmates. The Trump-era review rejected that reliance after medical professionals called those standards into serious question.
The bureau repeatedly cited Justice Clarence Thomas’ concurrence in U.S. v. Skrmetti, the 2025 Supreme Court decision that, by a 6-3 vote, allowed states to ban these procedures for minors. Officials pointed to that concurrence while explaining why the old recommendations no longer tracked the latest scientific information.
Federal health authorities have already flagged thin evidence in a related setting. A Department of Health and Human Services peer-reviewed report found “extremely weak evidence” for any benefits from sex-rejecting procedures for minors. Internal WPATH files also show members worried that minors cannot consent to interventions with lifelong effects. In 2022, WPATH left age recommendations out of its Standards of Care after political pressure from then-Assistant Secretary of Health Rachel Levine.
Medicine was not the only issue. Independent of the clinical debate, the Bureau of Prisons concluded the interventions create real prison problems. Inmates who receive them can become “targets for attacks.” The changes “raise fairness concerns” and “breed resentment among other inmates.” Some steps would help inmates “hide contraband” or “obfuscate or conceal” their identity.
The new rules restrict breast padding, chest binders, makeup, and wigs. The bureau will still provide mental health treatment. It will reject requests to begin sex-rejecting medical procedures. For inmates already on hormones, staff will build a tapering plan after weighing the right factors for each person.
That approach tracks a broader pattern of the administration reasserting control over contested federal policies, much as it has in other high-stakes legal fights such as when the Supreme Court lets Trump DHS scrub illegal immigrants from voter rolls.
A district court judge saw it differently. The judge ruled that the Bureau of Prisons had not adequately considered “its own experience providing gender-affirming care under its prior policy,” labeled the policy “objectively unreasonable,” and said it was “pretextual and reverse engineered to implement” President Donald Trump’s executive orders.
The D.C. Circuit left the injunction standing on Sept. 18. That is what sent Sauer to the Supreme Court. The administration’s position is straightforward: the bureau did the review, built the record, explained the science and the security stakes, and should not be forced to keep delivering interventions it no longer believes are medically justified or operationally safe.
Prison policy is not the only arena where this White House has moved to reverse prior Democratic baselines. Similar course corrections have shown up in refugee policy, including when the Trump administration caps 2027 refugee admissions at 17,500, prioritizing groups it says face real persecution.
The three anonymous plaintiffs frame the limits as unconstitutional cruelty and illegal discrimination. Their lawyers at the ACLU Foundation of Washington, D.C., and the Transgender Law Center argue the Eighth Amendment, Fifth Amendment equal-protection principles, the Rehabilitation Act, and the Administrative Procedure Act all bar the bureau’s turn.
The government’s counter is the record itself. A 3,200-page administrative file and a 43-page memo are not a shrug. They document why officials no longer treat WPATH recommendations as controlling, why hormone starts and surgeries are off the table, why social props like binders and wigs are restricted, and why mental-health care remains available while medicalization is not.
Personnel moves have reinforced the same governing posture. After months of acting status, Trump makes Rubio’s National Security Adviser role permanent, locking in a team aligned with the administration’s hard line on institutional drift.
The district court’s “pretextual” charge hangs over the briefing. Sauer’s answer is that the bureau’s conclusions stand on evidence and prison realities, not politics. The memo’s language on WPATH, ideological advocacy, misrepresented evidence, low-quality support for high-impact recommendations, is the spine of that defense.
Under President Barack Obama, federal prison officials treated WPATH as the authority that green-lit sex-rejecting procedures for inmates. The Trump administration’s review tore that foundation down. Officials now say the latest science undercuts the old reliance, and Thomas’ Skrmetti concurrence gives the legal and medical critique a Supreme Court hook.
The timeline is clear enough even without every docket stamp. WPATH’s 2022 Standards of Care dropped age lines after pressure from Rachel Levine. HHS later published a peer-reviewed finding of extremely weak evidence of benefit for minors. The bureau assembled thousands of pages, wrote a long memorandum, and changed course. Inmates sued. A district judge blocked the policy. The D.C. Circuit kept the block. Sauer asked the Supreme Court to lift it.
Other Trump-centered stories this month have shown the same friction between institutional inertia and executive direction, including coverage of how GOP senators clash with Trump over red-carpet welcome for China’s Xi. The prison fight is different in subject, same in structure: who sets the rules when prior orthodoxy collapses under scrutiny.
For taxpayers and for the officers who run federal facilities, the practical stakes are not abstract. If surgeries, cross-sex hormones, and identity props increase assault risk, fuel resentment, and aid concealment, the bureau has a duty to say no. If the leading specialty group is practicing politics more than medicine, prisons are the wrong place to keep pretending otherwise.
The Supreme Court now has the injunction question. Sauer wants the lower-court order gone so the Bureau of Prisons can enforce the limits it already justified on the record. The inmates and their counsel want the old pathway kept open under constitutional and statutory banners. The memo, the page count, the security findings, and the WPATH critique are what the administration is putting on the table.
Federal prisons are not clinics for contested ideology. When the evidence weakens and the security costs rise, the people who run those facilities should be allowed to stop.
