Definition
An appellate court is a court that reviews decisions made by a lower tribunal. Its primary function is not to retry facts but to examine whether the lower court applied the law correctly, followed proper procedure, and reached a legally supportable result. When an appellate court finds error, it may affirm, reverse, modify, or remand the case to the court below.
Appellate courts sit above trial courts in the judicial hierarchy. Most systems organize review in two tiers: an intermediate appellate court (such as a U.S. Circuit Court of Appeals or a state court of appeals) and a court of last resort (such as the U.S. Supreme Court or a state supreme court). Both tiers qualify as appellate courts; the distinction is one of position in the hierarchy, not of kind.

Common Confusion
APPELLATE COURT vs. TRIAL COURT: The most persistent confusion is treating these as interchangeable. A trial court (court of original jurisdiction) hears witnesses, receives evidence, and resolves disputed facts. An appellate court almost never receives new evidence or testimony. It works from the record created below. A researcher who finds a decision from an appellate court is reading a legal ruling on how the law was applied to facts already established, not a fresh examination of what happened.
APPELLATE COURT vs. COURT OF REVIEW: These are functionally synonymous. "Court of review" is the older formal usage; "appellate court" is now standard. Both appear in the historical dictionaries. Researchers in older materials should treat them as equivalent.

Why It Matters in Research
Appellate courts generate the decisions that shape legal doctrine. Trial court rulings bind the parties before them; appellate rulings create precedent. For most legal research purposes, the appellate record — briefs, oral argument transcripts where available, and the written opinion — is where doctrine is made and found.
Several navigational traps appear repeatedly in the Law Mind corpus:
JURISDICTION TO HEAR APPEALS IS NOT ALWAYS AUTOMATIC. Appellate courts may exercise discretionary review (certiorari at the U.S. Supreme Court level, and increasingly at intermediate levels) or mandatory review depending on the type of case and the court. Whether review was discretionary or as-of-right affects how much weight to give a refusal to hear a case. A denial of certiorari, for example, carries no precedential weight on the merits.
REMAND ORDERS CREATE SPECIFIC RESEARCH CHALLENGES. Not all appellate decisions end a case. A remand sends the matter back to the lower court, sometimes with narrow instructions, sometimes with broad ones. The Law Mind Civil Procedure encyclopedia entry civpro_9 addresses the particular complexity of remand under 28 USC 1447 in the federal removal context, where appellate review of remand orders is sharply restricted — a trap for researchers who assume all appellate decisions are reviewable on the standard record.
SPECIALIZED APPELLATE TRACKS EXIST OUTSIDE THE GENERAL COURT SYSTEM. Tax Court decisions, for example, do not flow through the normal trial-court-to-circuit-court path in the same way as district court cases. Researchers working in tax materials should consult tax_178 for the specific appellate review structure governing Tax Court decisions, which varies depending on which circuit the taxpayer resides in and which court issued the original ruling.
HISTORICAL SOURCES USE MULTIPLE JURISDICTIONAL LABELS. In older materials, "appellate court" may refer specifically to a named court in a particular state rather than to the functional category. Several states have courts titled "Court of Appeals" that are actually courts of last resort (New York's Court of Appeals, for instance), while others use the same title for an intermediate court. Do not assume the label maps to the same tier across jurisdictions or eras.

Historical Dictionary Support
Black's Law Dictionary and Burrill's Law Dictionary are in close agreement on this term, each defining an appellate court as a court possessing jurisdiction over appeals and review of lower-court decisions. Black's adds the specific mechanisms — appeal, certiorari, and writ of error — by which cases reach such a court, which is a useful reminder that "writ of error" was the dominant vehicle for appellate review in earlier American and English practice before it was largely abolished in federal courts in 1928. Researchers working in materials predating that reform will encounter writ-of-error practice where modern sources would use "appeal" or "certiorari."
Neither historical dictionary addresses the two-tier appellate structure that became standard in American federal courts after Congress created the Circuit Courts of Appeals in 1891, or the development of discretionary certiorari jurisdiction. The historical definitions describe a function accurately but capture a simpler structural moment. Modern use of the term carries considerably more institutional architecture than either source reflects.

Jurisdictional Note
Every U.S. jurisdiction has at least one appellate court, but the tier structure varies. Some states (including Delaware, Maine, and Nevada historically) operated without an intermediate appellate court, routing appeals directly to the court of last resort. States that have added intermediate courts in recent decades may have older corpus materials that predate that tier entirely.
