Definition
Ico regis (Latin: "by royal employment" or "in the king's service") is a writ addressed to a bishop, commanding him to refrain from molesting or penalizing a clerk on account of non-residence at his benefice, where that clerk's absence from his living is attributable to his employment in the king's service. The writ operates as a royal protection: because the clerk's non-residence is caused by obligations owed to the Crown rather than by neglect or dereliction, the ordinary canonical penalties for non-residence are suspended. The bishop receiving the writ is bound to discharge the clerk from liability for the absence.
Common Confusion
Ico regis belongs to a family of writs operating at the intersection of royal authority and ecclesiastical jurisdiction. It should not be confused with the writ of quare impedit (which addresses the right to present a clerk to a living) or with writs of prohibition (which restrained ecclesiastical courts from exceeding their jurisdiction). Ico regis does not contest the bishop's general authority over clergy; it carves out a narrow royal exemption from one consequence of that authority — the penalty for non-residence.
Why It Matters in Research
This term appears almost exclusively in sources dealing with the medieval and early modern interface between the English Crown and the Church of England, particularly the governance of benefices and the obligations of clergy holding royal appointments. Researchers working in ecclesiastical law, the history of the royal household, or the development of writs will encounter ico regis only in older registers and digests. The Registrum Omnium Brevium (Reg. Orig.), cited in Rapalje & Lawrence at folio 58, is the primary source for the writ's form, and consultation of that register is essential for anyone working with the writ's actual language and procedural operation.
A key research trap: because this writ was designed to protect clerks serving the Crown, its practical context overlaps with the broader body of law governing pluralism and non-residence that was repeatedly reformed by parliamentary statute — most significantly by the Pluralities Acts of the nineteenth century. By the time these statutes fundamentally restructured the law of benefices, writs like ico regis had become historical curiosities rather than living instruments. Any search in post-1838 materials for ico regis as an operative writ will likely be fruitless. Searches in canon law digests, the Year Books, and the older abridgments (Fitzherbert, Brooke, Viner) are more productive for understanding the writ's practical use.
The corpus connection most useful to researchers: ico regis sits within the Law Mind materials on writs of royal protection and ecclesiastical jurisdiction. It belongs alongside writs like ne admittas, indicavit, and duplex querela as instruments mediating between secular and spiritual authority over the English parish clergy.
Historical Dictionary Support
Rapalje & Lawrence provide the sole dictionary coverage identified for this term. Their entry is brief but precise: it identifies the writ's addressee (the bishop), its operative command (not to molest), the specific ground of protection (royal service causing non-residence), and the procedural result (discharge). The citation to Reg. Orig. 58 is the authoritative anchor. No other historical dictionaries in the standard reference shelf — not Bouvier, not Black's early editions — carry a distinct entry for ico regis, which reflects both the term's narrow compass and its obsolescence as a practical instrument well before American law developed its own legal literature. The absence of ico regis from American legal dictionaries is itself informative: the writ was a product of the established Church's relationship with the English Crown, a relationship that had no counterpart in the post-colonial American legal order.
Jurisdictional Note
Ico regis is an English writ with no American counterpart. Its relevance is confined to the ecclesiastical law of England and, by extension, to historical research into English canon law and the law of benefices. Researchers working in American law will encounter this term only in English sources or in comparative historical treatments.
