The question

Whether a pretrial order denying a federal contractor the protection recognized in Yearsley v. W. A. Ross Construction Co. is immediately appealable under the collateral-order doctrine.

Geo Group, Inc. v. Menocal

What the Court decided

The Court held that a pretrial order denying Yearsley protection to a federal contractor is not immediately appealable. Yearsley supplies contractors a potential merits defense, not an immunity from suit, so a denial does not fall within the small class of collateral orders that may be appealed before final judgment. The class action against GEO Group over its detainee labor policies may therefore proceed in the District Court.

The Court's opinion

Kagan, joined by Roberts, Sotomayor, Gorsuch, Kavanaugh, Barrett, Jackson, Thomas

Yearsley gives federal contractors a potential merits defense against liability, not an immunity from suit. Under 28 U.S.C. 1291, appellate jurisdiction generally reaches only final decisions that resolve the entire case. The collateral-order doctrine allows immediate appeal only for a small class of orders meeting the three Cohen conditions, and an order denying Yearsley protection does not qualify, so it is not immediately appealable. Thomas joined this opinion as to Parts I and III.
