Definition
A Latin phrase meaning "to consult" or "for the purpose of consultation." The phrase appears in classical common law texts to describe the consultative function of certain legal authorities or officers — specifically, the role of learned persons, judges, or advisors whose purpose is to provide counsel rather than to act or decide. In early English legal writing, it was used to characterize the advisory capacity of the justices and legal sages who attended the king or the courts not to render final judgment but to inform it.
Why It Matters in Research
This phrase is encountered almost exclusively in foundational common law sources — Bracton and Blackstone's Commentaries being the primary locations. Researchers will not find it in modern statutory texts or contemporary case law. Its significance is structural: it signals the distinction between consultative and decisional authority in early English legal institutions, a distinction that bears on understanding how medieval and early modern courts were composed and how advisory roles were conceived before the modern separation of judicial and counsel functions hardened.
When reading Bracton (fol. 5b) or Blackstone (1 Bl. Com. 227), encountering ad consulendum flags a passage about institutional design — who was present to advise, and in what capacity. Researchers tracing the history of judicial advisory functions, the role of the judiciary in non-adjudicative settings, or the development of the legal profession as distinct from the judiciary will find the phrase a useful marker.
Because the phrase appears in only a narrow band of historical sources, a researcher who finds it in a manuscript or treatise citation is likely working with foundational common law materials. It is not a term of art that migrated into equity, admiralty, or American common law usage in any significant way.
Historical Dictionary Support
Burrill's Law Dictionary renders the phrase concisely: "To consult; for the purpose of consultation," with reference to Bracton fol. 5b and 1 Bl. Com. 227. This entry is accurate as far as it goes but offers no analytical context. Burrill treats it as a passive definitional gloss rather than locating it within the institutional framework it was used to describe.
Blackstone's use at 1 Bl. Com. 227 situates the phrase in his account of the constitution of Parliament and the consultative role of the judges — called to attend not as members but as advisors on matters of law. Bracton's usage is consistent: learned persons summoned ad consulendum were present for the benefit of the deliberating body, not as principals in the decision. Neither Bracton nor Blackstone treats the phrase as a formal term of art requiring extended definition; it functions as descriptive Latin prose in both sources.
No other major historical law dictionaries — not Jacob's, not Bouvier's, not Black's early editions — carry a dedicated entry for ad consulendum. Its absence from those sources reinforces that this is a phrase drawn from specific classical texts rather than a term with broad circulation in legal practice or pleading.
Jurisdictional Note
The phrase has no meaningful presence in American or modern Commonwealth legal usage. It is relevant solely as a textual marker in historical English common law sources, particularly those engaging with Bracton or reproducing Blackstone's institutional descriptions.
