Definition
To reverse a judgment, decree, or order is the act of an appellate court setting aside, annulling, or vacating the decision of a lower tribunal upon finding it erroneous in law or fact. Reversal undoes the legal effect of the lower court's ruling and typically returns the parties to the position they occupied before that ruling, or remands the matter for further proceedings consistent with the appellate court's direction.
Two distinct but related uses appear in legal sources:
1. REVERSE (verb): The action of an appellate court in formally setting aside a lower court's judgment or decree. The court "reverses" when it finds the ruling below was wrong and cannot stand.
2. REVERSAL (noun): The resulting decision or act — the formal pronouncement that the lower court's judgment is erroneous and therefore annulled. Distinguished from affirmance, which confirms the lower court's ruling, and from modification, which changes but does not wholly undo it.
Common Language
Modern common usage (Wiktionary): Opposite or contrary in direction; to go in an opposing direction; turned upside down.
Historical common usage (Webster's 1913): "Turned backward; having a contrary or opposite direction; hence, opposite or contrary in kind."
The common meaning of "reverse" carries the intuitive sense of going backwards or undoing something, which aligns loosely with the legal use. The gap worth noting: in ordinary English, "reverse" is often spatial or directional. In law, reversal is a formal legal act by a court with specific procedural consequences — it is not merely an opinion that the lower court was wrong, but an authoritative order annulling that court's legal effect. A researcher encountering "reversed" in a case history must understand that legal consequences flow from the formal reversal, not from any informal disagreement with the lower ruling.
Common Confusion
REVERSE vs. OVERRULE: These are frequently conflated. To reverse applies to a specific judgment or decree in the case on appeal — it undoes the outcome between the parties in that proceeding. To overrule applies to a prior legal precedent or rule — it rejects or repudiates the holding of an earlier case as a statement of law going forward, typically without disturbing the parties in the overruled case. Anderson's explicitly flags this distinction with a cross-reference to OVERRULE.
REVERSE vs. REMAND: A reversal may stand alone (the appellate court disposes of the matter outright) or be paired with a remand (sending the case back for further proceedings below). The two are not synonymous. "Reversed and remanded" is a common combined disposition; "reversed" alone signals the appellate court has ended the matter in favor of the appellant without directing further trial-level action.
REVERSE vs. VACATE: Vacatur sets aside a judgment but does not necessarily imply the judgment was wrong on the merits — it may reflect procedural grounds, mootness, or settlement. Reversal carries an affirmative finding of error.
Why It Matters in Research
Researchers working with case law, reporters, and digests will encounter "reversed," "reversed and remanded," "reversed and rendered," and "reversed in part" as standard disposition notations in case histories. Each carries distinct procedural meaning and affects how the case can be cited as authority.
Shepard's and KeyCite negative treatment flags use "reversed" as a significant subsequent history marker. A case that has been reversed on appeal is no longer good law for the proposition it stood for, though it may remain citable for issues unaffected by the reversal. Researchers must distinguish between a case reversed on its specific facts or procedural posture and one reversed in a way that repudiates its central legal holding.
In older reporters and digests, the notation "rev'd" or "reversed" in case tables does not always specify whether the reversal was on the merits, on procedural grounds, or partial. Historical sources require careful verification against the full appellate opinion.
The term also appears in compound legal phrases — reverse discrimination, reverse mortgage, reverse veil piercing — where "reverse" signals an inversion of the usual direction or burden of a legal doctrine. These compounds have no direct connection to the appellate meaning and are treated separately in the Encyclopedia.
Historical Dictionary Support
Anderson's Dictionary of Law provides the cleaner and more practically useful definition: "To set aside, annul, vacate: as, to reverse a judgment," with the note that reversal is "the act or decision of one court in pronouncing erroneous, and therefore annulling, the judgment or decree of a lower court." Anderson's accurately marks its opposition to affirmance and its distinction from overrule — still the correct analytical framework today.
Rapalje & Lawrence is fragmentary on this term. The entry reads as though corrupted or partially transcribed, mixing a definition of "reverse" with extraneous material about feudal tenures and revels. What survives is useful: "A judgment is said to be reversed when it is set aside by an appellate court," and a parallel note on decrees. The citations to 14 Wend. (N.Y.) 666 and 7 Kans. suggest the term was being applied consistently to both judgments and decrees by the mid-nineteenth century.
Neither historical dictionary addresses the compound uses of "reverse" (reverse mortgage, reverse discrimination) because those doctrines post-date both works. Neither distinguishes with precision between reversal and vacatur, a distinction that has become more practically important as modern procedural rules and appellate practice have formalized those categories.
Jurisdictional Note
The procedural consequences of reversal — whether the appellate court may render final judgment itself or must remand — vary by jurisdiction and by court rules. Some jurisdictions permit the appellate court to "reverse and render," disposing of the case outright; others require remand in most circumstances. Federal appellate practice and individual state rules on this point differ enough that researchers should not assume uniform procedure.
