Justices Samuel Alito, Brett Kavanaugh, and Clarence Thomas joined liberal Justices Sonia Sotomayor and Ketanji Brown Jackson in a 5, 4 Supreme Court ruling that expanded the reach of a century-old doctrine limiting when Americans can take their state-court disputes into federal court. The decision in T.M. v. University of Maryland Medical System Corporation scrambled the usual ideological lines, and produced a sharp dissent from Justice Amy Coney Barrett, who warned the majority was building on a legal foundation that "stands on shaky ground."
The case turned on the Rooker-Feldman doctrine, an arcane but consequential legal rule that bars federal district courts from functioning as appellate courts for state-court judgments. The question before the justices: Does that bar still apply when the state-court judgment is being appealed within the state system? The majority said yes.
For anyone who follows the Court's work, the lineup alone is worth attention. Three of the Court's most reliable conservatives joined its two most liberal members to form the majority, while Barrett wrote for a dissenting bloc that included Chief Justice John Roberts, Neil Gorsuch, and, notably, liberal Justice Elena Kagan. Procedural cases sometimes produce odd coalitions, but a split this clean, with conservatives and liberals swapping partners on both sides, is rare enough to signal something deeper about how the justices see the structural boundaries between state and federal courts.
The facts underlying the case are grim. In March 2023, a patient identified only as T.M. accidentally ingested gluten, triggering a medical episode. T.M. was taken to the emergency room at Baltimore Washington Medical Center. Court documents indicated T.M. was then held involuntarily at the hospital for approximately three months. During that time, the hospital obtained an order authorizing forcible injections of antipsychotic medication.
T.M.'s father objected to the involuntary hospitalization. T.M.'s parents filed several state and federal lawsuits seeking her release and opposing the forced injections. Eventually, a settlement was reached. On June 12, 2023, a state judge entered the settlement agreement as a consent order in a state habeas petition proceeding. Under the terms, T.M. was released, but several conditions applied, including a requirement that all pending cases against the facility be dismissed with prejudice.
Ten days later, T.M. and her parents obtained new counsel and took two simultaneous steps: they appealed the consent order to the Appellate Court of Maryland, and they filed a new complaint in federal district court. The federal suit sought a declaration that the consent order violated T.M.'s due process rights.
The federal district court dismissed the complaint for lack of jurisdiction, invoking the Rooker-Feldman doctrine. The case eventually reached the Supreme Court on the narrow but significant question of whether that doctrine applies when a state-court judgment is still subject to appellate review within the state system.
Justice Sotomayor, writing for the five-justice majority, framed the answer as obvious. As Newsweek reported, Sotomayor wrote:
"This case asks whether this rule bars suit when the state court judgment at issue is subject to further review in state appellate proceedings. A straightforward application of the logic and reasoning underlying Rooker-Feldman leads to one conclusion: It does."
The doctrine traces its name to two Supreme Court decisions, Rooker v. Fidelity Trust Co. in 1923 and District of Columbia Court of Appeals v. Feldman in 1983. Together, they established that federal district courts cannot serve as appellate courts for state-court judgments. Only the U.S. Supreme Court itself, under §1257, has that authority.
T.M. argued that the doctrine should not apply while a state-court judgment remained on appeal, that federal district courts should be free to review state rulings that had not yet become final. Sotomayor rejected that argument directly, writing that T.M.'s theory "cannot be squared with this Court's precedents, which plainly adopted a different, more functional view of original and appellate jurisdiction." She characterized the plaintiff's position as requiring "a reimagining, rather than an application, of the Court's Rooker-Feldman precedents."
The majority opinion also warned that accepting the dissent's approach would force the Court to "abandon a central part of Rooker's reasoning and reinterpret the doctrine to rest solely on a strict negative inference from §1257." In other words, the majority saw the dissenters as trying to shrink a doctrine that the Court's own precedents had already settled.
The ideological cross-pollination in this case is not without precedent. Recent Supreme Court rulings have occasionally produced surprising alignments when the question at hand is structural rather than politically charged.
Justice Barrett wrote a dissent joined by Roberts, Gorsuch, and Kagan, a coalition that itself defies easy categorization. Barrett did not hold back about the doctrine the majority chose to expand. She wrote that Rooker-Feldman "stands on shaky ground" and that the Court has "consciously kept its footprint small."
"Its rationale has gotten no firmer, so we should make the doctrine no larger."
Barrett went further, arguing that the doctrine lacks a solid statutory foundation. She wrote that "parts of the United States Code undercut it," and that the doctrine "is in tension, to say the least, with statutes granting district courts jurisdiction in categorical terms."
Barrett's critique echoes concerns raised by lower-court judges. In a 2020 Sixth Circuit ruling in VanderKodde v. Mary Jane M. Elliott, Judge Jeffrey Sutton wrote that the Rooker-Feldman rule has "caused so much mischief, creating needless complications, distracting litigants and courts from the properly presented federal issues at hand, and helping no one, not even the supposed beneficiaries of its largesse: state court judgments."
That a conservative-appointed appellate judge and a conservative Supreme Court justice both view the doctrine with suspicion, yet three other conservative justices voted to expand it, illustrates how jurisdictional questions can cut across ideological lines in ways that policy disputes rarely do.
The practical effect of the majority's holding is clear: if you lose in state court and want to challenge the outcome, you cannot run to federal district court while your state appeal is still pending. The Rooker-Feldman bar now applies regardless of whether the state-court judgment is final or still under review within the state system.
For litigants like T.M., that narrows the available paths. The family's federal due-process claim, that the consent order was constitutionally deficient, cannot be heard by a federal trial court. The only federal avenue is the Supreme Court itself, and only after state appellate proceedings have concluded.
The University of Maryland Medical System Corporation, the defendant, expressed satisfaction. In a written statement to Newsweek, the system said the ruling "provides important clarity regarding the legal framework governing state court proceedings." The statement added: "We appreciate the Supreme Court's careful consideration of this matter and its decision today and are pleased that the Supreme Court justices agreed with our position, which affirms the legal principles and longstanding precedent in this case."
The Court's willingness to expand a doctrine that even some of its own members view as poorly grounded raises a question Barrett's dissent left hanging: if the rationale has never been firm, why extend it? The majority's answer, that precedent demands it, is the kind of institutional conservatism that appeals to justices who prize stability over doctrinal purity. That three of the Court's most conservative members found that argument persuasive, while Barrett and Gorsuch did not, reveals a genuine fault line within the right-of-center legal movement.
It is worth noting that Justice Jackson has sometimes found herself isolated even from her liberal colleagues on the bench. In this case, however, she joined Sotomayor in the majority, while Kagan broke away to side with Barrett's dissent.
Cases like this rarely generate headlines, but they shape the architecture of American law. The Rooker-Feldman doctrine determines which courthouse door is open to you, and which one is locked. For families facing the kind of ordeal T.M.'s family described, involuntary hospitalization, court-ordered injections, a settlement entered under duress, the question of whether a federal judge can hear your constitutional claims is not academic. It is the difference between having a remedy and having none.
The majority's position carries a logic that conservatives have long respected: federal courts should not second-guess state courts on matters the state system is equipped to resolve. That principle supports federalism and limits the sprawl of federal judicial power. Barrett's dissent, however, raises an equally conservative objection: courts should not expand doctrines that lack a firm textual basis in the statute.
Both sides of that debate are grounded in principles the right takes seriously. The split is not about politics. It is about which brand of judicial restraint wins when two versions collide.
The case also carries echoes of broader tensions seen in recent Supreme Court arguments where justices from both wings have pressed hard on questions of jurisdictional limits and executive authority. The current Court is less predictable on structural questions than many observers assume, a fact this ruling underscores.
Several questions remain unanswered. The outcome of T.M.'s state appellate challenge to the consent order is not addressed in the ruling. Whether the family has any remaining avenue to press due-process claims in federal court, beyond a long-shot Supreme Court petition, is unclear. And the broader question Barrett raised, whether Rooker-Feldman rests on solid enough statutory ground to justify its continued expansion, will almost certainly return to the Court in a future case.
Behind the scenes, the justices bring different temperaments and instincts to these disputes. But on the published page, this ruling is a reminder that the most consequential decisions often come in cases nobody is watching, and that the justices who agree on headline-grabbing culture-war cases can land on opposite sides when the question is how the system itself is supposed to work.
When the Court's conservatives split three against two and each side recruits a liberal to fill out the numbers, the old scorecards don't apply. The only thing that matters is whether the reasoning holds, and on that, the argument is far from over.
