Appeals, the Final Judgment Rule, and Claim/Issue Preclusion
Key Takeaways
- Under the final judgment rule (28 U.S.C. 1291), appeals lie only from a final judgment that ends the litigation on the merits; a notice of appeal is generally due within 30 days of entry of judgment.
- Exceptions include interlocutory injunction orders (28 U.S.C. 1292(a)), certified controlling questions (1292(b)), Rule 54(b) certification of fewer than all claims, the collateral order doctrine, and mandamus.
- Claim preclusion (res judicata) bars relitigation when there is a valid final judgment on the merits, the same claim (same transaction), and the same parties or their privies.
- Issue preclusion (collateral estoppel) bars relitigation of an issue that was actually litigated, actually determined, and essential to a valid final judgment.
- California uses a 'primary rights' theory of claim preclusion (one right invaded = one claim) and permits nonmutual defensive issue preclusion, while mutuality requirements have largely been abandoned federally (Parklane Hosiery).
The Final Judgment Rule and Its Exceptions
Under 28 U.S.C. 1291, federal courts of appeals have jurisdiction over appeals from final decisions — the final judgment rule. A decision is final when it ends the litigation on the merits and leaves nothing for the court to do but execute the judgment. The notice of appeal is generally due within 30 days after entry of judgment (60 days if the United States is a party).
Exceptions allowing interlocutory appeal
| Route | Authority | What it permits |
|---|---|---|
| Injunctions | 28 U.S.C. 1292(a) | Appeal of orders granting, denying, or modifying injunctions |
| Certified question | 28 U.S.C. 1292(b) | District court certifies a controlling question of law with substantial ground for difference; court of appeals must agree to hear it |
| Rule 54(b) | FRCP 54(b) | Trial court enters final judgment on some but not all claims/parties, finding 'no just reason for delay' |
| Collateral order doctrine | Cohen v. Beneficial | Order that (1) conclusively determines a disputed question, (2) resolves an important issue separate from the merits, and (3) is effectively unreviewable on appeal from final judgment (e.g., immunity denials) |
| Mandamus | All Writs Act | Extraordinary writ to correct a clear abuse of power |
| Class certification | Rule 23(f) | Discretionary appeal of an order granting/denying class certification |
Standards of review: questions of law are reviewed de novo; findings of fact are reviewed for clear error (Rule 52(a)); discretionary rulings for abuse of discretion; and harmless errors are disregarded.
Claim Preclusion (Res Judicata)
Claim preclusion (res judicata) prevents a party from relitigating a claim that was or could have been raised in a prior action. It requires three elements:
- A valid, final judgment on the merits in the first action. (Dismissals for failure to state a claim, after trial, by summary judgment, and most Rule 41(b) dismissals are 'on the merits'; dismissals for lack of jurisdiction, venue, or joinder are not.)
- The same claim in both actions. The majority/federal 'transactional' test (Restatement (Second)) treats all rights to relief arising from the same transaction or occurrence as a single claim — so a plaintiff must assert all theories and remedies in one suit or lose them.
- The same parties (or those in privity with them).
- Effect: Claim preclusion merges a winning plaintiff's claim into the judgment and bars a losing plaintiff from refiling. It is an all-or-nothing doctrine covering the entire transaction.
The four elements restated, and the 'could have been raised' reach
Courts often phrase claim preclusion as four elements: (1) an identical claim; (2) a final judgment; (3) on the merits; and (4) identity (or privity) of parties. The doctrine reaches not only theories actually pleaded but every theory that could have been raised as part of the same transaction — this is the bar to claim-splitting.
A default judgment and a consent judgment are 'on the merits' for preclusion purposes even though no trial occurred, while a dismissal without prejudice is not. Privity extends preclusion to successors-in-interest, those who controlled the prior litigation, and parties adequately represented in a class action — but never to a stranger, consistent with the due-process rule that a nonparty may not be bound.
California's 'primary rights' theory
California does not use the transactional test. Under the primary rights theory, a 'claim' is defined by the primary right invaded — a single injury to one primary right is one cause of action, even if multiple legal theories exist. Key distinction: because personal injury and property damage from a single accident invade two different primary rights, a California plaintiff may bring separate suits for each (a result barred under the federal transactional test). This is a frequently tested California CivPro point.
Issue Preclusion (Collateral Estoppel)
Issue preclusion (collateral estoppel) bars relitigation of a specific issue already decided, even in a suit on a different claim. It requires:
- The issue was actually litigated and actually determined in the first action;
- The determination was essential (necessary) to the first judgment; and
- The first judgment was valid and final.
Unlike claim preclusion, issue preclusion can apply to a single issue without barring the whole claim.
The mutuality question — who can use it?
Traditionally, only a party (or privy) to the first suit could invoke preclusion (mutuality). Modern federal law has abandoned strict mutuality:
- Defensive nonmutual issue preclusion: a new defendant uses a prior loss by the plaintiff to bar the plaintiff from relitigating an issue the plaintiff already lost (Blonder-Tongue). Broadly allowed.
- Offensive nonmutual issue preclusion: a new plaintiff uses a prior judgment against the defendant to establish an issue the defendant already lost (Parklane Hosiery Co. v. Shore). Allowed at the court's discretion, but disallowed where the plaintiff easily could have joined the first action ('wait and see'), or where the defendant lacked incentive to litigate fully, or there are inconsistent prior judgments.
- Due process floor: issue preclusion can never be used against a person who was not a party to the first action and had no full and fair opportunity to litigate.
California distinctions
California (now using the terms 'claim preclusion' and 'issue preclusion') similarly allows nonmutual preclusion. California historically embraced defensive nonmutual estoppel (Bernhard v. Bank of America) and permits offensive use under a fairness analysis. Combined with the primary-rights theory, California preclusion law diverges enough from federal doctrine that essay answers should flag which jurisdiction's rule governs.
A plaintiff loses a tort suit; a jury finds the defendant was not negligent. A different plaintiff, injured in the same accident, now sues the same defendant and seeks to use the prior finding to establish negligence. What governs whether this is allowed?
A plaintiff is injured and her car is damaged in one car accident in California. She sues only for personal injury and wins, then files a second suit for the property damage. Under California law, is the second suit barred by claim preclusion?
