Definition
To overrule is to supersede, annul, or render without authority a prior legal ruling or decision. The term carries two distinct uses in legal practice:
1. Overruling a precedent. A judicial decision is overruled when a later decision — issued by the same court or by a superior court within the same judicial system — reaches a conclusion directly opposite to the earlier one on the same question of law. The effect is that the original decision is stripped of its precedential authority; it can no longer be cited as binding on future courts. Overruling operates prospectively as a matter of doctrine: the earlier case ceases to govern, though the judgment in that specific case may stand undisturbed. This is the primary legal meaning of the term.
2. Overruling an objection or motion. In trial practice, a judge overrules an objection when rejecting it — finding the objection without merit and allowing the challenged evidence, question, or conduct to proceed. This usage is the opposite of sustaining an objection. The same verb applies when a court denies or rejects a motion or other procedural request.
The two uses share a structural logic — authority is exercised to reject or negate something — but they operate in entirely different contexts and carry different consequences.

Common Language
Modern common usage (Wiktionary): To rule over or govern by superior authority; to rule or determine in a contrary way; to nullify a previous ruling by a higher power; to dismiss an objection at court.
Historical common usage (Webster's 1913): To rule over; to govern or determine by superior authority; to rule or determine in a contrary way; to decide against, abrogate, or alter.
The common and legal meanings overlap more closely for this term than for most legal vocabulary, but one gap matters for researchers. In ordinary English, "overrule" connotes a superior simply outranking a subordinate — a manager overruling a subordinate's decision. In law, overruling precedent requires the same court or a hierarchically superior court, but crucially, a court cannot overrule its own decision through a ruling in an unrelated case merely by expressing disagreement. Overruling requires a direct confrontation with and repudiation of the prior holding on the same legal question. The informal sense of "overrule" as any exercise of superior will does not capture this doctrinal precision.

Common Confusion
OVERRULE vs. REVERSE: These terms describe related but distinct actions. To reverse is to overturn the judgment in a specific case on appeal — the losing party wins, and the case outcome changes. To overrule is to repudiate a prior decision's legal reasoning or holding as precedent. A case can be reversed without being overruled (the appellate court corrects an error in that specific case), and a case can be overruled without being reversed (the judgment stands, but the precedent is gone). Researchers encountering older opinions must attend to which action is described; loose historical usage sometimes blurs this line.
OVERRULE vs. DISAPPROVE: Courts sometimes "disapprove" or "question" a prior decision without formally overruling it — a softer form of doctrinal skepticism that does not strip the earlier case of precedential authority. Disapproval signals doubt; overruling ends authority. In historical sources, the distinction is not always crisp.
OVERRULE vs. ABROGATE: Abrogation typically describes legislative or executive action nullifying a rule or right. Overruling is a judicial act. The terms are not interchangeable when precision matters.

Why It Matters in Research
The primary research trap is treating overruled cases as live authority. When tracing a legal doctrine across the Law Mind corpus, confirming whether a key decision has been overruled is an essential step before relying on it. The Law Mind corpus contains decisions and secondary sources from periods when now-overruled cases were still good law. A treatise from 1890 citing a case as authoritative does not establish that the case remains good law today, or even that it was good law at the time the researcher is studying.
Several complications arise in historical research:
First, overruling is not always explicit. Courts sometimes adopt reasoning that is functionally irreconcilable with a prior decision without formally declaring it overruled. Later courts or commentators may characterize the earlier case as "implicitly overruled" or "no longer good law" — language that will not appear in the original decision.
Second, the scope of overruling matters. A court may overrule a specific holding within a decision while leaving other holdings intact, or may limit a prior case without overruling it. Historical sources sometimes describe these partial actions imprecisely.
Third, overruling operates within a judicial system. A federal circuit court cannot overrule a Supreme Court precedent; a state intermediate court cannot overrule the state supreme court. When reading historical sources describing one court as overruling another, verify that the hierarchical relationship supports the claim.
Fourth, in constitutional law, the stakes of overruling are distinctly high, and the doctrine of stare decisis applies with special intensity — or, in some periods, special flexibility. The Law Mind Constitutional Law Encyclopedia entry on stare decisis addresses the doctrinal framework governing when the Supreme Court overrules itself.

Historical Dictionary Support
The historical dictionaries converge on the core definition without significant disagreement. Black's (both editions) specifies that overruling requires a later decision by the same court or a superior court in the same system — a precision that matters doctrinally and that the Black's entry flags as necessary to the proper use of the term. Black's also notes that the term is "not properly" applied outside this context, a caution that survives into modern practice.
Bouvier adds a useful observation that the historical dictionaries otherwise underemphasize: overruling also applies within a single proceeding, when a majority of judges of a court decides against the minority opinion. This captures the intracourt usage and gestures toward the objection-overruling sense.
Rapalje & Lawrence offer only a brief entry directing the reader to "set aside the authority of a former decision" — functional but thin compared to Black's and Bouvier's.
None of the historical sources meaningfully address the trial-practice usage (overruling objections), which in modern courts is perhaps the more frequent everyday use of the term. This is a gap. The judicial-opinion meaning dominates the historical dictionaries because that is where doctrinal stakes were highest. Researchers using these sources for guidance on evidentiary procedure will find limited support.
