Whether a State or state entity claiming Eleventh Amendment immunity may immediately appeal a district court order denying that claim under the collateral-order doctrine.
Holding
Yes. An order denying a State's or qualifying state entity's claim of Eleventh Amendment immunity is immediately appealable under the collateral-order doctrine.
Reasoning
Section 1291 generally permits appeals only from final decisions, but Cohen v. Beneficial Industrial Loan Corp. recognizes a narrow category of collateral orders that may be appealed immediately. Under Coopers & Lybrand v. Livesay, such an order must conclusively resolve the disputed question, decide an important issue separate from the merits, and be effectively unreviewable after final judgment.
A denial of Eleventh Amendment immunity conclusively decides, at that stage, that the State or asserted arm of the State has no right to avoid suit in federal court. The immunity question ordinarily is distinct from the underlying merits, which here concerned whether PRASA breached its engineering contract with Metcalf & Eddy.
Eleventh Amendment immunity is an immunity from suit, not merely a defense against eventual liability. Like qualified immunity for government officials, its central benefit is substantially lost if the State must endure discovery, trial, and the coercive process of a federal court before it can obtain appellate review.
The Court rejected the view that Ex parte Young shows the Amendment provides only a defense to liability. Young instead creates a narrow exception for certain suits seeking prospective relief against state officers; it does not permit suits against States or their agencies themselves. Those entities retain immunity from federal suit absent waiver or a valid congressional abrogation.
The rule rests not only on litigation costs but also on state sovereignty and dignity. The Eleventh Amendment protects States from the indignity of being haled into federal court by private parties, and delayed review cannot fully repair that injury. The Court therefore reversed the First Circuit and remanded for it to consider PRASA's actual entitlement to immunity.
