Issue Versus Claim Preclusion

Issue Preclusion

Issue Versus Claim Preclusion

A final judgment can follow the parties into later litigation in two distinct ways, and most of this chapter depends on keeping them apart. Courts draw the line this way: under res judicata, a final judgment on the merits bars further claims by the parties or their privies on the same cause of action; under collateral estoppel, once a court of competent jurisdiction has actually and necessarily determined an issue, that determination is conclusive in later suits on a different cause of action involving a party to the first case.¹ This chapter uses the modern labels: claim preclusion for the first doctrine, issue preclusion for the second. The Restatement (Second) of Judgments states the second rule in one sentence. When an issue of fact or law is actually litigated and determined by a valid and final judgment, and the determination is essential to the judgment, the determination is conclusive in a subsequent action between the parties, whether on the same or a different claim.²

A third label, direct estoppel, covers the rare case in which an issue returns in a second suit on the very same cause of action. Claim preclusion usually extinguishes such a suit outright, so direct estoppel does its work mainly after a first judgment that was not on the merits. The issues actually litigated and necessarily determined in that proceeding then bind the parties in later suits on the same cause of action.³ If the parties litigated the court’s jurisdiction and the court decided it, for example, direct estoppel forbids reconsidering that question in a later suit on the same cause of action between the same parties in the same court.⁴

Claim preclusion looks at the whole lawsuit. Suppose a driver sues for personal injuries from a collision and later sues the same defendant for the damage to her car. Both harms arose from one occurrence, so most courts today would bar the second action: the driver already sued over this accident and is not entitled to a second bite at the apple.⁵ The bar reaches even grounds she never raised, because claim preclusion prevents parties from raising issues that could have been raised and decided in the prior action, whether or not anyone actually litigated them.⁶

Issue preclusion works on a smaller scale. Claim preclusion prevents the second suit altogether, but issue preclusion does not prevent suit; it merely compels the court to make the same finding of fact that the first court made on the identical issue.⁷ Every question the first case did not decide stays open for the second.⁸

A lease dispute shows the narrower doctrine at work. A landlord sues her tenant over the meaning of a subletting clause, and the court decides it. The next year the tenant sublets again, and the landlord sues again. Claim preclusion does not bar the second suit, because it rests on new facts that had not occurred when the first case was tried. Issue preclusion, however, will probably stop the loser of the first round from relitigating what the clause means. That question is the same one litigated and decided before, and if it was fairly decided the first time, a second trial would only waste the resources of the parties and the court.⁹

Issue preclusion also reaches farther than claim preclusion. A litigant’s exposure to it is potentially much broader, and almost all of the modern expansions of preclusion law involve issue preclusion.¹⁰ That breadth carries a risk of surprise: an issue that appeared trivial in one action may be crucial in a later suit, and an unwary litigant may regret having handled it laxly the first time.¹¹

To offset that exposure, the common law added a requirement that claim preclusion does not share: the issue must actually have been litigated and decided. Issue preclusion does not apply to issues that could have been litigated but were not. The requirement confines the doctrine to points the parties really contested, and it makes a reliable result more likely, to the extent that the adversarial process improves fact-finding.¹² The classic statement of the limit comes from Cromwell v. County of Sac. When a second action rests on a different claim, the earlier judgment estops only as to matters actually in issue, and the inquiry “must always be as to the point or question actually litigated and determined in the original action, not what might have been thus litigated and determined.”¹³ Claim preclusion asks what could have been raised; issue preclusion asks only what was.¹⁴

A trespass dispute shows both sides of that line. Smith sues Jones over a first cutting of timber and loses, because the court finds that Jones holds a valid easement. When Jones returns to cut wood again and Smith sues over the second incident, claim preclusion does not bar the suit, since she is not suing over the same incident. Smith is still collaterally estopped from trying again to prove the easement invalid, because that issue was litigated and decided.¹⁵ She remains free to argue that an implied condition of the easement required payment for the timber, since no one raised or decided that point in the first action.¹⁶

The same line protects a defendant who stayed silent. A landlord sues a tenant for one installment of rent under a lease and wins. In a later suit for subsequent installments under the same lease, the tenant is not estopped from denying that the lease was ever executed. Execution was not actually litigated and decided in the first action, so issue preclusion does not apply, even though the tenant could have raised it as a defense then.¹⁷

Why accept a rule that can bind a party to a finding that may be wrong? Issue preclusion assumes that even if an issue was wrongly decided in the first action, the parties had a full and fair opportunity to present their case on it, and systemic concerns must prevail; res judicata takes the same reasoning one step further.¹⁸ Barring parties from contesting matters they have fully and fairly litigated spares their adversaries the expense and vexation of multiple suits, conserves judicial resources, and fosters reliance on judicial action by minimizing the possibility of inconsistent decisions.¹⁹ The elements of the test earn that trade. The party invoking issue preclusion must show that the identical issue was presented in both actions and was actually litigated and necessarily decided in the first, and each element assures that preclusion follows only after a full opportunity to litigate the particular issue. Once that assurance exists, judicial economy becomes paramount.²⁰

Because preclusion trades accuracy for finality, a mistaken finding must be attacked within the case that produced it. Preclusion rules apply only to new actions; they do not apply to a party seeking a new trial or reversal on appeal in the same action.²¹ A litigant who believes the first court got an issue wrong must therefore say so there, because otherwise the finding will govern later suits.

Two further questions come later in the chapter: who may be bound by a prior determination, and which jurisdiction’s preclusion law governs a judgment from another court. On the second, one possibility is to read the Full Faith and Credit Clause as giving a sister-state judgment the same effect in the second forum that it has in its home state, since giving full faith and credit to a sister-state law means letting that law operate according to its own terms.²²
