Definition
A Court of Errors and Appeals is a high-level appellate tribunal, historically constituted as the court of last resort in certain American states. The name reflects two strands of appellate jurisdiction that were sometimes treated as distinct: the correction of errors of law (proceeding in the nature of a writ of error) and the review of equitable determinations (proceeding in the nature of an appeal proper). In practice, courts bearing this name exercised general supreme appellate authority over the courts below them.
Three principal courts carried this designation:
1. NEW JERSEY: The Court of Errors and Appeals was the highest court in the state, sitting above the Supreme Court of New Jersey. It was composed of the Chancellor, the justices of the Supreme Court, and lay judges known as "judges of the Court of Errors and Appeals." This unusual composition — mixing legal and non-lawyer members — made it structurally distinctive among American appellate courts. It was abolished by the New Jersey Constitution of 1947, which created the modern New Jersey Supreme Court in its place.
2. NEW YORK: An earlier court of the same name served as New York's highest appellate tribunal before the establishment of the New York Court of Appeals by the Constitution of 1846. The New York Court of Errors and Appeals was similarly composed of the Chancellor, the justices of the Supreme Court of Judicature, and the state's senators — a design that drew sustained criticism for placing legislative officers in judicial roles.
3. MISSISSIPPI: The High Court of Errors and Appeals served as Mississippi's court of last resort. Black's Law Dictionary (2nd Ed.) expressly notes this variant title.

Common Confusion
Researchers sometimes confuse the Court of Errors and Appeals with the ordinary Supreme Court of a state, or assume the name signals a court of limited or intermediate jurisdiction. Neither assumption is correct. In each jurisdiction where the title appeared, this court occupied the apex of the judicial hierarchy — it was not a mid-level error-correction body. The confusion is compounded by the fact that New Jersey maintained both a "Supreme Court" and the Court of Errors and Appeals simultaneously, with the latter ranking above the former. A researcher encountering a New Jersey case decided "in the Supreme Court" before 1947 should not assume that decision was final; it could have been reviewed by the Court of Errors and Appeals.
Separately, do not conflate this court with modern specialized appellate tribunals such as the United States Tax Court's appellate track or the Court of Appeals for the Armed Forces, which carry different names, statutory bases, and jurisdictional limits entirely.

Why It Matters in Research
This term is primarily a historical research trap. The court no longer exists in any of the jurisdictions where it operated, and researchers encountering it in case reporters, briefs, or secondary sources must orient themselves carefully.
Several navigational points:
CITATION FORMATS VARY BY JURISDICTION AND ERA. New Jersey decisions of the Court of Errors and Appeals appear in New Jersey Law Reports and New Jersey Equity Reports under varying citation conventions across the nineteenth and early twentieth centuries. New York decisions from the earlier court appear in older reporters such as Johnson's Cases and Caines' Cases, well before the modern New York Reports series began with the Court of Appeals.
THE MIXED-MEMBERSHIP PROBLEM. Because New Jersey's court included non-lawyer members and New York's included sitting senators, opinions from these courts sometimes reflect political or non-doctrinal pressures not present in purely professional judicial bodies. Researchers using these decisions as precedent sources should be alert to this structural feature when assessing the persuasive weight of reasoning.
EQUITY VERSUS LAW JURISDICTION. The dual nomenclature — "errors" (law) and "appeals" (equity) — reflects the historical separation of law and equity that characterized pre-merger American courts. In researching the procedural history of a case, the distinction matters: a writ of error proceeding and an appeal in equity followed different procedural rules, and the court's authority to act could depend on which vehicle was used.
ABOLITION DATE IS CRITICAL. For New Jersey, 1947 is the hard cutoff. Any New Jersey appellate authority attributed to this court after 1947 is mislabeled; the successor body is the New Jersey Supreme Court. For New York, the transition occurred a full century earlier, in 1846.
THE MISSISSIPPI VARIANT. Black's flags the "High Court of Errors and Appeals" as the Mississippi equivalent. Researchers working in Mississippi legal history should note this title distinction when searching historical reporters and digests.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) provides a compact but reliable treatment, identifying New Jersey, New York, and Mississippi as the three principal jurisdictions. The entry is characteristically terse and purely descriptive, offering no analysis of the structural oddities of these courts or their historical significance.
What Black's does not address — and what researchers should supply from other sources — is the controversy surrounding the mixed legislative-judicial composition of the New York court, which was a recurring target of reformers in the early nineteenth century and a driver of the 1846 constitutional revision. Similarly, Black's does not note the abolition of the New Jersey court in 1947, which occurred after the 2nd Edition's publication window, meaning any edition-dependent research must account for subsequent constitutional change not reflected in the dictionary text.
Historical legal dictionaries generally treat this term as a proper noun pointing to specific institutions rather than as a generic category of court, which is the correct approach. The name did not become a traveling label applied broadly; it was institution-specific.

Jurisdictional Note
The Court of Errors and Appeals existed only in New Jersey (abolished 1947), New York (superseded 1846), and Mississippi (under the variant title "High Court of Errors and Appeals"). No federal court and no other state court carried this designation. Researchers should not expect to find the term in jurisdictions outside these three states.
