Definition
A procedural device by which a disputed question of law is extracted from a trial and submitted to a higher court for resolution before or in lieu of a final verdict. Rather than allowing a jury to decide the full matter and risk a general verdict on uncertain legal ground, the parties — or the presiding judge — arrange to have the controlling legal question stated in writing and referred upward for authoritative determination.
In its classical English form, a special case arose at nisi prius when the trial judge concluded that the outcome turned on a point of law rather than disputed fact. The jury would return a general verdict conditioned on the court's resolution of that legal question. Counsel for both sides would then collaborate on a written statement of agreed or stipulated facts — the "special case" document itself — to be argued before the court in banc.
The term operates in two related but distinct senses:
1. STATED CASE / SPECIAL CASE (procedural mechanism): The formal written document setting out stipulated facts submitted to a superior court for its opinion on the legal question they raise. This is the core historical meaning.
2. AGREED CASE (as cross-reference): Bouvier treats "special case" as synonymous with "agreed case," pointing to a procedure in which both parties stipulate facts and jointly request a legal ruling, bypassing trial altogether. The two terms overlap substantially but the agreed case is typically a wholly consensual pretrial device, while the special case could arise during trial itself.
Common Language
Modern common usage (Wiktionary): A specialized instance of a more general phenomenon, category, or rule; something that falls within a broader class but has particular distinguishing features.
Historical common usage (Webster's 1913): Not a term of art in common usage; the phrase carried its ordinary compositional meaning — a case (instance) that is special (particular or exceptional).
The gap here is directional. In ordinary English, "special case" suggests something unusual or exceptional within a broader category. In the legal historical sense, it names a specific procedural instrument — a defined mechanism for referring legal questions upward — not merely any unusual legal situation. A researcher who reads "special case" in a 19th-century English report and assumes it means simply an unusual matter will miss that it refers to a formal procedural artifact with its own rules and consequences.
Common Confusion
Special case is frequently conflated with case stated, stated case, and agreed case. These terms describe the same or closely related procedures but carry different emphasis across jurisdictions and periods. "Case stated" is the dominant modern British and Commonwealth term for the procedure by which a lower court or tribunal refers a legal question to a higher court; "special case" is the older English nisi prius formulation for largely the same device. "Agreed case" (Bouvier's preferred term) emphasizes the consensual, stipulated-facts dimension. Researchers working across English, American, and Commonwealth sources from different periods may encounter all four labels for what is functionally the same mechanism.
Why It Matters in Research
The primary research trap is anachronism. "Special case" as a formal procedural device was far more prevalent in 19th-century English practice than in modern American law. American federal procedure absorbed and transformed the device; what remains in U.S. courts is largely the certified question mechanism under 28 U.S.C. § 1292(b) and analogous state procedures — functionally similar but differently named and governed. A researcher following citations from English equity or common law reports into American sources must recognize that the procedural label changed even when the underlying concept persisted.
A second trap involves the document versus the proceeding. Historical sources sometimes use "special case" to mean the written statement of facts submitted to the court, and sometimes to mean the entire proceeding in which that document played a role. Black's definition focuses on the mechanism; Bouvier's cross-reference to agreed case focuses on the consensual fact-stipulation dimension. Neither fully resolves the ambiguity for a researcher trying to reconstruct what a historical "special case" actually produced — an advisory opinion, a conditional judgment, or a binding ruling on remand.
For corpus researchers, the term appears most frequently in English nisi prius materials, equity reports, and early American appellate practice. It becomes rarer in American sources after the mid-20th century as codified interlocutory appeal procedures displaced the informal special case mechanism. When the term appears in American state court records from the 19th century, researchers should check whether the jurisdiction had adopted any statutory analog to the English procedure, as practice varied considerably.
Historical Dictionary Support
Black's provides the most substantive account, grounding the term in English nisi prius practice and correctly identifying the two-stage structure: a conditional general verdict at trial, followed by argument before the court in banc on the written statement of facts. This is the technically precise historical definition and the most useful starting point for research in English and early American sources.
Bouvier's cross-reference to AGREED CASE reflects a genuine procedural overlap but flattens the distinction between a device that could arise during trial (special case proper) and one that was wholly pretrial and consensual (agreed case). Researchers using Bouvier as their sole source will miss the nisi prius context.
Burrill's bare cross-reference to CASE adds nothing distinctive and should be treated as a placeholder rather than a substantive definition.
None of the historical dictionaries address the transition of this procedure into modern American practice, the development of certified question statutes, or Commonwealth variants. For those dimensions, researchers must move beyond the historical shelf sources.
Jurisdictional Note
The special case procedure in its classical form is an English common law mechanism and remains recognizable in modern English, Australian, and other Commonwealth practice under the label "case stated." American federal and state courts developed parallel mechanisms — certified questions, interlocutory appeals — that are functionally related but governed by distinct procedural rules. Researchers should not assume that English authorities on special case procedure translate directly to American jurisdictions.
