Definition
Diets of compearance are the designated days within which parties in civil or criminal proceedings are required by citation to appear before a court. The term is drawn from Scots law: "diets" refers to appointed court days or sitting dates, and "compearance" (also spelled "compearance") denotes the act of appearing before a tribunal in response to a legal summons. Together, the phrase describes the window of court dates—fixed by the citation itself—within which a party must formally present themselves or suffer consequences for non-appearance.
Why It Matters in Research
This is a Scots law term with no direct equivalent in English common law or American legal tradition. Researchers encountering it in historical sources should situate it firmly within the Scottish civil and criminal procedural framework, where the citation and compearance system operated differently from English pleading conventions.
The term appears almost exclusively in older Scots legal materials and in dictionaries that incorporated Scots law entries—particularly those relying on Bell's Law Dictionary of Scotland. When working through historical Scottish court records, practitioners' manuals, or pleading guides from the eighteenth and nineteenth centuries, a researcher will find "diets" used broadly to mean any appointed court date, and "compearance" used to mean the formal act of appearance. The combined phrase has a technical precision that neither word alone carries: it refers specifically to the cited days, not simply any date of appearance.
The risk in historical research is treating "diets" as a generic synonym for "proceedings" or misreading "compearance" as a variant spelling with different meaning. In Scots procedure, failure to appear within the diets of compearance could result in a decree in absence or other default consequence, making the precise computation of these dates legally significant in the underlying records.
Because this term does not translate neatly into English or American procedural vocabulary, researchers using multi-jurisdictional historical databases should be alert to the possibility of false cognates—English procedural documents do not use this phrase, and its appearance in a source is itself a reliable marker that the document originates in or is addressing Scottish legal practice.
Historical Dictionary Support
Black's Law Dictionary and Bouvier's Law Dictionary are in close agreement on this term, and both trace the definition to Bell—a reference to William Bell's Dictionary and Digest of the Law of Scotland, a foundational source for Scots legal terminology in the nineteenth century. Both entries define diets of compearance as the days within which parties in civil and criminal prosecutions are cited to appear, with no meaningful divergence between them.
Notably, Black's entry contains what appears to be an editorial corruption or printing error in the surviving text: it references citation "by the abbreviation 'Dig.' instead of 'Ff.,' as formerly" and the phrase "Sometimes called to appear. Bell. 'Digest,' in the singular." This text reads as garbled—likely the result of a typesetting error that merged the diets of compearance entry with fragmentary text from an adjacent entry on "Digest" or "Digesta." Researchers should treat the Black's entry with caution and rely on Bouvier's cleaner formulation, or go directly to Bell's original dictionary, for authoritative content.
Neither historical dictionary elaborates on the procedural consequences of non-appearance within the diets, the method by which these days were computed, or how the citation system in Scots law compared to English process. For that depth, Bell's Dictionary and Digest of the Law of Scotland and institutional writers such as Erskine's Institute of the Law of Scotland are the appropriate primary sources.
Jurisdictional Note
This term is specific to Scots law and has no operative meaning in English common law jurisdictions or in American legal practice. Researchers working in Scottish historical records or comparative common law contexts will encounter it; those working exclusively in English or American sources will not.
