Definition
Res judicata (Latin: "a thing adjudged") is the doctrine that a final judgment on the merits by a court of competent jurisdiction is conclusive as to the rights of the parties and their privies, and bars relitigation of the same claim or cause of action in any subsequent proceeding. Once a matter has been fully and finally decided, it cannot be litigated again between the same parties. The doctrine operates through two related but distinct mechanisms: 1. CLAIM PRECLUSION (res judicata in the narrow sense): A final judgment on the merits extinguishes the entire claim, including all grounds that were raised or could have been raised. A party who wins or loses on a cause of action may not split the claim or bring a second action on facts that arose from the same transaction or occurrence. 2. ISSUE PRECLUSION (collateral estoppel): A specific factual or legal issue that was actually litigated and necessarily decided in a prior proceeding cannot be relitigated in a subsequent action, even if the second action involves a different claim. This is a separate doctrine that is frequently grouped with res judicata under the general heading of "preclusion law." The underlying policy rationale is threefold: finality of judgments, judicial economy, and protection of litigants from the burden and harassment of repetitive litigation. The doctrine applies in both civil and criminal contexts, though its criminal application (double jeopardy) is governed by distinct constitutional rules.
Common Confusion
RES JUDICATA VS. COLLATERAL ESTOPPEL These doctrines are related but distinct. Res judicata (claim preclusion) bars the entire claim once a final judgment has been entered. Collateral estoppel (issue preclusion) bars only the relitigation of specific issues previously decided — it can apply even when the second lawsuit involves a different claim. Historical sources, including Black's and Bouvier's, often use "res judicata" to encompass both doctrines. Modern courts and treatises draw the line sharply. Researchers reading older cases should not assume the court is using the term in the narrower modern sense.
Core Elements
For res judicata (claim preclusion) to bar a subsequent action, courts generally require: 1. A final judgment on the merits — dismissal for lack of jurisdiction, lack of standing, or other procedural grounds typically does not trigger res judicata. 2. A court of competent jurisdiction — the original court must have had authority to render the judgment. 3. The same parties or their privies — the doctrine binds parties and those in privity with them; strangers to the prior action are generally not bound. 4. The same claim or cause of action — courts use varying tests (same transaction, same evidence, same primary right) to determine whether claims are identical for preclusion purposes.
Why It Matters in Research
Res judicata is a foundational procedural doctrine and a researcher navigating the Law Mind corpus will encounter it across virtually every subject area — civil procedure, contracts, property, family law, and constitutional law. Several research traps deserve attention. TERMINOLOGICAL DRIFT: Historical sources use "res judicata" to cover both claim preclusion and issue preclusion without consistently distinguishing them. The modern analytical separation between res judicata and collateral estoppel was not fully consolidated until the twentieth century. Black's first edition entry uses "res judicata" expansively, in the classical civil-law tradition. When reading pre-twentieth-century cases or dictionary entries, treat "res judicata" as a general term for preclusion and look carefully at the facts to determine which specific mechanism the court actually applied. THE CIVIL LAW MAXIM: Black's preserves the Roman law maxim — "Res judicata facit ex albo nigrum; ex nigro, album; ex curvo, rectum; ex recto, curvum" (a thing adjudged makes white black, and black white; the crooked straight, and the straight crooked). This maxim reflects the classical view that a judgment has legal force regardless of its substantive correctness. It is frequently quoted in early American treatises and opinions and appears in Bouvier's Institutes. Understanding this maxim helps explain why courts historically gave preclusive effect even to judgments later suspected to be wrong. FORMER RECOVERY AS A DEFENSE: Rapalje & Lawrence indexes "former recovery" as a related procedural defense. In historical pleading, a former recovery was the specific plea used to assert res judicata at common law. Researchers using pre-code pleading materials should cross-reference "former recovery," "former judgment," and "estoppel by judgment" to locate cases that modern researchers would classify under res judicata. PRIVITY: The privity requirement is an evolving area. Historical sources define it narrowly. Modern courts have expanded privity in certain contexts (successive property owners, class actions, virtual representation). Researchers examining modern preclusion questions should not rely solely on historical definitions of privity. CRIMINAL CONTEXT: In criminal law, res judicata principles overlap with but are not identical to the constitutional double jeopardy protection. A criminal acquittal on the merits will bar retrial (double jeopardy) and may also preclude relitigation of specific factual issues in subsequent proceedings (Ashe v. Swenson established this principle under the Fifth Amendment). Researchers should treat criminal preclusion as a distinct area governed by constitutional doctrine, not merely by common-law res judicata principles.
Historical Dictionary Support
Black's Law Dictionary provides the foundational entry, tracing "res judicata" directly to civil law origins and quoting the Latin maxim from Bouvier's Institutes (no. 840) and Kent's Commentaries (2 Kent, Comm. 120). The entry treats the doctrine as settled and universally recognized, consistent with its status as one of the oldest continuous doctrines in Anglo-American law. Black's formulation — "a thing or matter settled by judgment" — is broad and encompasses both modern preclusion doctrines without distinguishing them. Bouvier's Law Dictionary, in the passages recovered in the source material, does not directly define res judicata by that heading but addresses related doctrines in the context of stare decisis and prior decisions. Bouvier's discussion of when circuit courts of appeals are bound by Supreme Court decisions (citing 35 U.S. App. 67) situates res judicata within a broader discussion of when prior adjudications bind future decision-making — a related but distinct concept. Bouvier's Institutes (no. 840), cited by Black's, contains the classical maxim and provides the doctrinal foundation. Rapalje & Lawrence, as a case-law dictionary rather than a doctrinal treatise, indexes "former recovery" with case citations from Indiana and New York courts (including early New York Reports: 2 Johns. 227; 5 Johns. 129; 7 Johns. 20, 22; 8 Johns. 383). These early nineteenth-century New York cases represent the American common-law development of the doctrine and confirm that by the early 1800s, former recovery as a bar to relitigation was well-established in American practice. The Rapalje entry uses "former recovery" rather than the Latin term — a reminder that legal practitioners working in common-law pleading often avoided the civilian vocabulary. Taken together, the sources reflect consistent agreement on the core rule: a judgment finally decides the matter between the parties and bars relitigation. The sources diverge only in vocabulary and in the degree to which they extend the doctrine to cover issue preclusion, with the classical formulations remaining broader and less analytically refined than modern doctrine.
Jurisdictional Note
Federal courts apply res judicata to prior federal judgments under federal common law. For the preclusive effect of state court judgments in federal court, 28 U.S.C. § 1738 (the Full Faith and Credit statute) requires federal courts to give state judgments the same preclusive effect they would have in the rendering state — meaning the law of the state where the first judgment was entered governs the preclusion analysis. This creates significant variation, as states differ on questions of privity, the scope of the same-claim requirement, and the treatment of default judgments.

EXCEPTION (Lat. excipere: ex, out of, capere, to take). In Contracts. A clause in a deed by which the lessor excepts something out of that which he before granted by the deed. The exclusion of something from the effect or operation of the deed or contract which would otherwise be included. An exception differs from a reservation (q. v.),-the former being always of part of the thing granted, the letter of a thing not in esse, but newly created or reserved; the exception is of the whole of the part excepted; the reservation may be of a right or interest in the particular part affected by the reser- vation. See 5 R. I. 419; 41 Me. 177; 42 id. 9; 51 id. 493; 19 Barb. 102; 2 B. & C. 197. The two words, however, are often used indiscriminately; 129 Mass. 231; 88 Conn. 541. An exception differs, also, from an explanation, which, by the use of a videlicet, proviso, etc., is allowed only to explain doubtful clauses precedent, or to separate and distribute generals into particulars; 8 Pick. 272. To make a valid exception, these things must concur: first, the exception must be by apt words, as, "saving and excepting," etc.; see 30 Vt. 242; 5 R. I. 419; 41 Me. 177; 102 N. C. 14; second, it must be of part of the thing previously described, and not of some other thing; third, it must be of part of the thing only, and not of all, the greater part, or the effect of the thing granted: 11 Md. 339; 23 Vt. 395; 10 Mo. 426; see 146 Pa. 451; an exception, there- fore, in a lease which extends to the whole thing demised is void; fourth, it must be of such thing as is severable from the demised premises, and not of an inseparable incident; 33 Pa. 251; 37 N. H. 167; fifth, it must be of such a thing as he that excepts may have, and which properly belongs to him; sirth, it must be of a particular thing out of a general, and not of a particular thing out of a particular thing; seventh, it must be particularly described and set forth; a lease of a tract of land except one acre would be void, because that acre was not partic- ularly described; Co. Litt. 47 a; 12 Me. 237; Wright, Ohio 711; 8 Johns. 375; 8 Conn. 369; 6 Pick. 499; 6 N. H. 421; 4 Strobh. 208; 2 Tayl. 173; see 91 Cal. 74; 112 N. C. 58. Exceptions against common right and general rules are construed as strictly as possible; 1 Bart. Conv. 68; 5 Jones, N. C. 63. When a grantor makes a valid exception, the thing excepted remains the property of himself or his heirs; but if he has no valid title to it, neither he nor his heirs can recover; 97 N. C. 95. In Equity Practice. The allegation of a party, in writing, that some pleading or proceeding in a cause is insufficient. In Civil Law. A plea. Merlin, Répert. Declinatory exceptions are such dilatory exceptions as merely decline the jurisdic- tion of the judge before whom the action is brought. La. Code Proc. Dilatory exceptions are such as do not tend to defeat the action, but only to retard its progress. Declinatory exceptions have this effect, as well as the exception of discussion offered by a third possessor or by a surety in an hypothecary action, or the exception taken in order to call in the war- rantor. 7 Mart. La. N. 8. 282; 1 La. 38, 420. Peremptory exceptions are those which tend to the dismissal of the action, Some relate to forms, others arise from the law. Those which relate to forms tend to have the cause dismissed, owing to some nullities in the proceed- ings. These must be pleaded in limine litis. Per- emptory exceptions founded on law are those which, without going into the merits of the cause, show that the plaintiff cannot maintain his action, either because it is prescribed, or because the cause of action has been destroyed or extinguished. These may be pleaded at any time prévious to definitive judgment; Pothier. Proc. Civ. pt. 1, c. 2, ss. 1, 2, 8. These, in the French law, are ca called Fins de non recevoir. In Practice. Objections made to the decisions of the court in the course of a trial. See BILL OF EXCEPTION.
