Whether the Supreme Court had jurisdiction to review the Court of Appeals’ dismissal of Nixon’s interlocutory appeal from the denial of absolute immunity.
Holding
Yes. The denial of Nixon’s claim of absolute immunity was immediately appealable under the collateral-order doctrine, and the case was properly before the Supreme Court.
Reasoning
Under Cohen v. Beneficial Industrial Loan Corp., an interlocutory order may be immediately appealed when it conclusively resolves an important issue separate from the merits and would be effectively unreviewable after final judgment. A denial of absolute immunity fits that description because immunity is not merely a defense to liability; it protects the official from the burdens of litigation itself.
Nixon’s appeal also raised a serious and unsettled question. Although the D.C. Circuit had previously rejected absolute presidential immunity, the Supreme Court had not decided the issue, and a certiorari petition in the earlier case remained pending. Claims that judicial proceedings threaten essential presidential prerogatives warrant particular attention under separation-of-powers principles.
