Christine Castro sued a nonprofit for misusing earmarked donations. The district court ordered the nonprofit to post donor names and amounts on its website. The nonprofit immediately appealed, claiming the order destroyed associational privacy rights that could never be restored after disclosure occurred. The appeal proceeded because the order finally resolved a right separate from the misuse claims and left no effective remedy after final judgment.
Clifford Cox sued former President Richard Nixon for damages arising from alleged wrongful termination. Nixon asserted absolute immunity and the district court denied the defense on summary judgment. Nixon appealed immediately. The court of appeals accepted jurisdiction because the immunity ruling conclusively settled a right not to face suit at all, an issue distinct from liability and lost once trial began.
Cassandra Cooper sued officers after a high-speed chase ended in gunfire. The district court denied qualified immunity on summary judgment with facts treated as undisputed. The officers appealed at once. Jurisdiction existed because the immunity denial resolved a claimed right to avoid trial, an issue separate from ultimate liability and irretrievably lost if review waited until after judgment.
Christopher Collins sued presidential aides for alleged First Amendment violations. The district court denied the aides' immunity defense. The aides appealed directly. The court of appeals exercised jurisdiction because the order conclusively rejected a right to avoid the burdens of litigation, a question separate from the merits and effectively unreviewable after trial.
Claire Campbell sued high-ranking officials alleging unconstitutional detention. The district court denied a motion to dismiss based on qualified immunity. The officials appealed. Jurisdiction attached because the ruling turned on an abstract legal question of immunity that was separate from factual merits and would be lost if the officials had to proceed to discovery and trial.
Chloe Chen sued her former employer for retaliation. The district court ordered production of privileged documents over the employer's objection. The employer appealed immediately. The appeal was dismissed because the privilege ruling, though important, remained reviewable after final judgment through harmless-error analysis and did not satisfy the unreviewability requirement.
The order must conclusively determine the disputed question. It must resolve an important issue completely separate from the merits of the action. It must be effectively unreviewable on appeal from a final judgment.

The denial conclusively resolves whether the defendant must stand trial. The immunity issue is separate from the ultimate merits of liability. The right to avoid the burdens of litigation is lost once trial begins and cannot be restored on appeal from final judgment.
…order was not an appealable "case" properly "in" the Court of Appeals within the meaning of § 1254. We do not agree. Under the "collateral order" doctrine of Cohen v. Beneficial Industrial Loan Corp. , 337 U. S. 541 (1949), a small class of interlocutory orders are immediately appealable to the courts of appeals. As defined by…

The order must conclusively decide the disclosure question. The asserted privacy or trade-secret right must be separate from the merits. Once disclosure occurs the harm is permanent and cannot be undone by later review, satisfying the unreviewability prong.

The denial conclusively resolves the bond issue. The cost-protection right is separate from the underlying negligence claims. The statutory protection against unfunded litigation would be lost if review waited until after trial, making the order effectively unreviewable.

They fail the separateness or unreviewability requirements. Any error can ordinarily be remedied after final judgment through sanctions, exclusion of evidence, or adjustment of costs. The doctrine therefore keeps such orders within the final judgment rule to avoid piecemeal appeals.
