Definition
To empanel (also spelled impanel) is to select and swear in a jury for service in a particular case. The process encompasses summoning prospective jurors, conducting voir dire examination, excusing jurors for cause or by peremptory challenge, and formally constituting the final jury that will hear and decide the matter. The term is used both as a transitive verb describing the court's act ("the court empaneled a jury") and, less commonly, as a noun referring to the jury list itself.

Common Language
Modern common usage (Wiktionary): Alternative spelling of impanel.
Historical common usage (Webster's 1913): A list of jurors; a panel. [Obs.]
The common language trail here is thin by design: both modern and historical general dictionaries treat empanel as simply a spelling variant pointing elsewhere. What those entries miss is the procedural weight the term carries in legal contexts — empanelment is not merely the clerical act of listing names but a formal legal event that triggers constitutional protections, marks the attachment of jeopardy in criminal cases, and sets the timeline for challenges and objections. A researcher who reads "empanel" as administrative bookkeeping will miss its doctrinal significance entirely.

Common Confusion
EMPANEL vs. IMPANEL: These are variant spellings of the same term, not distinct legal concepts. Impanel is the older and more frequently encountered form in historical sources; empanel appears with greater regularity in modern American usage. Neither spelling carries a different legal meaning. Researchers working across historical periods should treat the two as interchangeable and search both spellings when canvassing older materials.
EMPANEL vs. PANEL: Panel is the broader term — it refers to the list of persons summoned for jury duty or, in some usages, the entire jury. Empanel is the verbal act of constituting that body for a specific proceeding. The distinction matters when tracking procedural stages: a panel exists before empanelment; the jury exists after it.

Why It Matters in Research
The spelling variation is the first practical trap. Historical sources — including both Anderson's and Burrill's — normalize to impanel or direct the reader there without explanation. A full-text search in historical legal materials using only empanel will produce incomplete results. Always run parallel searches on impanel, empanel, and in older sources, enpanel.
Beyond spelling, the moment of empanelment carries constitutional significance in criminal cases: double jeopardy attaches when the jury is sworn, making the precise point of empanelment a live legal question in cases involving mistrials, retrials, and prosecutorial misconduct. Researchers working on double jeopardy questions in the Law Mind corpus should treat empanelment as a trigger event, not merely a procedural step.
Voir dire — the examination process that precedes empanelment — is closely intertwined but procedurally distinct. Sources discussing jury selection may treat empanelment as the conclusion of voir dire or as a separate event following it. Pay attention to how individual sources draw this line, because the characterization affects analysis of waiver, challenge preservation, and appellate review.
Civil and criminal contexts use the term in structurally parallel ways, but the stakes attached to the moment of empanelment differ sharply. In civil cases, empanelment does not trigger jeopardy and carries fewer of the constitutional consequences that make timing so significant in criminal proceedings. Sources written primarily for one context may assume facts that do not transfer to the other.

Historical Dictionary Support
Both historical sources treat empanel as derivative rather than independent. Burrill traces it explicitly to impanel, citing Cowell and Blount as authority for calling it the "old form of writing" — suggesting that even by the period of those authorities, impanel had become the dominant spelling. Anderson's dispenses with a separate entry entirely and redirects to panel.
This minimal treatment is informative in itself: it confirms that the term's historical legal significance lived in the root concepts of panel and impanel, not in empanel as an independent entry. Researchers should not read the thin dictionary treatment as evidence that the procedure was legally unimportant — it reflects orthographic consolidation, not substantive marginalization.
Neither historical source addresses the constitutional dimensions of empanelment, which developed primarily through later American case law. The historical dictionaries are reliable guides to the term's procedural meaning and spelling history but are not useful sources for the double jeopardy framework that now surrounds the concept.

Jurisdictional Note
The spelling empanel is more common in American legal usage; impanel and empanel both appear in state and federal materials without meaningful distinction. Grand jury empanelment follows procedural rules that vary by jurisdiction, particularly regarding public access, challenge rights, and the role of the court in selection.
