Definition
A bill of appeal was an ancient common-law procedure by which a private individual could initiate a criminal prosecution against another person for a serious crime — most notably felonies such as murder, rape, robbery, or mayhem — by filing a formal written complaint (the "bill") and, in the most solemn cases, offering to prove the accusation through personal combat. The accuser was called the "appellor" and the accused the "appellee." The proceeding was entirely distinct from a royal prosecution initiated by the Crown and operated instead as a private right of accusation, giving the injured party or a victim's kin a direct mechanism for obtaining criminal justice outside the ordinary indictment process.
The bill of appeal was closely intertwined with the wager of battle (trial by combat): when the appellor could not produce sufficient proof, the dispute could be resolved by mortal combat between the parties. This connection to battel was ultimately its undoing. As rational modes of proof displaced the ordeal and combat, the bill of appeal became an increasingly anomalous relic. In England, the procedure was formally abolished by statute in 1819 — prompted by the embarrassing case of Ashford v. Thornton (1818), in which a defendant actually claimed his right to trial by combat and the court was forced to acknowledge the claim was technically still available.
The bill of appeal should not be confused with a modern appellate brief or notice of appeal. It was not a mechanism for reviewing a prior court decision. It was an original, accuser-initiated criminal action.

Common Confusion
The word "appeal" in modern legal usage almost universally denotes a review of a lower court's decision by a higher court. The bill of appeal had nothing to do with appellate review. It was an original criminal prosecution — a first-instance proceeding — that happened to be called an "appeal" in the medieval sense of the word, meaning an accusation or a challenge. Researchers encountering "appeal" in early English legal sources must determine from context whether the term refers to this ancient accusatorial procedure or to something resembling modern appellate practice. The confusion is compounded because historical dictionaries and Year Books use "appeal" in both senses.

Why It Matters in Research
This term is almost exclusively a historical artifact. Researchers are unlikely to encounter the bill of appeal in any living legal context, but those working in English legal history, common-law criminal procedure, or the history of trial by combat will find it central to understanding how pre-modern criminal prosecution worked.
Several navigational points:
First, the bill of appeal is the procedural gateway to understanding battel. The two cannot be fully understood in isolation. Black's Law Dictionary's entry for BILL OF APPEAL simply cross-references BATTEL, and that cross-reference is the right instinct — the two topics are inseparable. Any research into wager of battle in criminal matters will require tracing the bill of appeal as the initiating mechanism.
Second, period sources — particularly Bracton, Glanvill, and Blackstone's Commentaries — discuss the bill of appeal at some length. Blackstone treats it in Book IV of the Commentaries under private prosecutions. These sources use technical vocabulary (appellor, appellee, fresh suit, vouching to warranty) that does not map cleanly onto modern criminal procedure concepts, and researchers should approach those terms with care.
Third, the 1818 Ashford v. Thornton case is historically significant precisely because it exposed how long this procedure had technically survived on the English books. The episode directly triggered the 1819 abolition statute (59 Geo. 3, c. 46). That sequence — a dormant procedure suddenly invoked, followed by rapid legislative abolition — is a useful illustration of how common-law archaisms can persist on the books long past any practical function.
Fourth, American law never fully received the bill of appeal as an operative procedure. American researchers examining colonial-era materials may find scattered references, but the procedure did not take root in the colonies in the way it remained (theoretically) available in England. This is worth flagging when working with comparative or colonial criminal procedure sources.

Historical Dictionary Support
Black's Law Dictionary offers only a minimal entry: "An ancient, but now abolished, method of criminal prosecution. See BATTEL." This is accurate as far as it goes but tells a researcher almost nothing about the mechanism, the historical period, or the reason for abolition. The cross-reference to BATTEL is the most useful navigational signal in the entry.
Older editions of Black's, along with Bouvier's Law Dictionary (1856 and later editions), provide somewhat more detail on the formal requirements of the bill — including the requirement of fresh suit (that the appellor pursue the accusation promptly), the specific crimes to which it applied, and the procedural steps leading to combat or compurgation. Bouvier's treatment is more expansive than Black's and may be more useful for researchers needing substantive procedural detail.
Blackstone's Commentaries remain the most accessible and thorough English-language synthesis of how the bill of appeal actually functioned in practice, and they should be the first stop for researchers who need more than a dictionary entry.
No historical dictionary entry adequately covers the American reception question or the 1819 abolition, which are better addressed through secondary historical scholarship than through the dictionary shelf.

Jurisdictional Note
The bill of appeal was an English common-law procedure, formally abolished in England in 1819. It was never enacted or systematically received in American jurisdictions, and no American state retains any analog. Scottish law developed separately and did not employ the bill of appeal in the same form.
