Geo Group, Inc. v. Menocal
The Supreme Court unanimously ruled that a private immigration detention company could not cut short a forced-labor lawsuit by immediately appealing a trial court's refusal to apply a contractor defense, because that defense only guards against being found liable — not against having to face trial in the first place.
The decision keeps open a long-running lawsuit by detainees who say GEO Group forced them to clean its facility without pay and clarifies that federal contractors invoking the Yearsley doctrine must wait for a final verdict before appealing an unfavorable pretrial ruling.
How it got here: The federal trial court denied GEO's motion to dismiss on Yearsley grounds; GEO immediately appealed; the Tenth Circuit dismissed for lack of jurisdiction; the Supreme Court agreed to hear the case.
The Case in Depth
What happened
GEO Group operates a private immigration detention facility in Aurora, Colorado, under a federal contract with Immigration and Customs Enforcement. A former detainee, Alejandro Menocal, sued on behalf of all detainees there, claiming that GEO forced them to clean the entire facility without pay — threatening up to 72 hours in solitary confinement for refusal — and paid other workers only $1 per day for cooking and laundry. GEO argued a legal doctrine called Yearsley shielded it from any lawsuit because ICE had authorized these policies.
The question before the Court
Can a private company running a federal immigration detention facility immediately appeal a trial court's refusal to dismiss a lawsuit under a legal protection that shields federal contractors who follow government directives?
The Court's answer
No — a federal contractor cannot immediately appeal when a trial court refuses to throw out a lawsuit under the Yearsley defense. Yearsley gives contractors only a defense to being found liable — not a shield against having to face a trial at all. Under the rules governing mid-case appeals, a right must be permanently lost the moment trial happens to justify bypassing the usual wait for a final verdict. True immunities work that way: once a defendant has gone through trial, the right to avoid it is gone forever. But Yearsley's protection — to a ruling of no liability because the contractor followed lawful government directives — can be fully vindicated after trial by winning an appeal of the final verdict.
The Court also rejected the argument that Yearsley gives contractors "derivative sovereign immunity" inherited from the government. Prior decisions have consistently held that the government's immunity from lawsuits does not extend to contractors who do its work, even under contract. Sovereign immunity belongs to the government alone.

Why it matters
Federal contractors — including private prison and detention companies — can no longer short-circuit lawsuits by immediately appealing when a trial court refuses to dismiss based on the Yearsley defense. They must go through discovery and trial first, then raise the issue on appeal if they lose. This keeps more contractor-liability cases alive longer, which matters most to plaintiffs like immigration detainees with limited resources to sustain prolonged litigation.
What changes now
The case returns to federal trial court in Colorado, where GEO Group must face trial on whether its labor policies violated the federal bar on forced labor and Colorado's prohibition on unjust enrichment. If GEO loses at trial and a final judgment is entered against it, it may then appeal — including by raising the Yearsley defense again. The ruling also means other federal contractors who invoke Yearsley will likewise have to wait for a final verdict before seeking appellate review, though trial courts can still certify exceptional cases for immediate appeal under a separate statutory process.
What this does not decide
The Court did not decide whether GEO Group's labor policies actually violated federal forced-labor law or Colorado's unjust enrichment prohibition — those merits questions return to the trial court. The ruling also does not address whether GEO could separately invoke qualified immunity, and it leaves open whether trial courts may certify Yearsley rulings for immediate appeal in exceptional cases under 28 U.S.C. § 1292(b).
Concurrences and dissents
How the Justices voted
Majority (7). Justice Kagan (author), joined by Justice Roberts, Justice Sotomayor, Justice Gorsuch, Justice Kavanaugh, Justice Barrett, and Justice Jackson.
Separate writings (2). Justice Thomas (author of a concurrence (in part)).
Concurrence in part — Justice Thomas
Justice Thomas agreed that Yearsley is a defense to liability and not an immunity from suit, and he agreed the Tenth Circuit's dismissal was correct. He did not join the majority's Part II, which applies the Cohen collateral-order doctrine, because he believes Cohen conflicts with Congress's authority to define appellate jurisdiction. In his view, judges should not create new categories of immediately appealable orders by judicial opinion — that work belongs to Congress and the rulemaking process — and the doctrine should not be extended beyond cases already held to qualify.
Concurrence — Justice Alito
Justice Alito agreed that Yearsley is not an immunity from suit and that immediate appeal is therefore unavailable. But he objected to the majority's reasoning that the test is simply whether a defense turns on the legality of the defendant's conduct. He would instead ask whether postponing appellate review would imperil important constitutional or public-policy interests — the same public-interest framework the Court has used in past immunity cases. Under that test, he agreed Yearsley does not qualify as an immunity because deferring review raises no serious separation-of-powers, sovereign-dignity, or overdeterrence concerns.

How the Court got there
The legal reasoning, step by step
- Federal law generally allows appeals only from 'final' decisions that end a case. A narrow exception called the collateral-order doctrine — developed from the Court's 1949 Cohen decision — allows immediate appeals of a small class of pretrial rulings that would become permanently unreviewable if not appealed right away. To qualify, a ruling must meet three strict conditions, including that the right at stake would be 'irretrievably lost' if the appeal had to wait.
- The Court focused on the third condition — whether the right at stake would be irretrievably lost — and explained that the answer turns on whether a defendant is asserting a true immunity from suit or merely a defense to liability. A true immunity, like sovereign immunity, protects a defendant from having to go through litigation at all; that right is permanently lost once trial occurs. A defense to liability, by contrast, only argues the defendant acted lawfully and should not be held responsible — that argument can be made just as effectively on appeal after a final verdict.
- The Court examined the 1940 Yearsley decision and concluded it supplies a merits defense, not an immunity. Yearsley protects a contractor only when it received a lawful government authorization and stayed within its bounds — meaning the protection disappears precisely when the contractor may have violated the law. Because every true immunity shields its holder even when they acted unlawfully, and Yearsley does not do that, Yearsley is a defense on the merits rather than a pass from the litigation process.
- GEO argued it possessed 'derivative sovereign immunity' — the government's own immunity transferred to it as a contractor. The Court rejected this by pointing to multiple prior decisions holding that the government's immunity from suit does not extend to its agents or contractors, regardless of whether they are acting on the government's behalf or under a government contract. Sovereign immunity is a prerogative of the sovereign itself, not something that passes along a contracting chain.
- Because Yearsley is a merits defense, a trial court's refusal to apply it does not strip away a right that is permanently lost at trial. If GEO is eventually found liable, it can raise the Yearsley argument on appeal at that point and, if it wins, have the liability finding reversed. The collateral-order doctrine therefore does not allow an immediate interlocutory appeal of a Yearsley denial.
