Definition
A Latin phrase meaning "to ask for right" or "to petition the judge to do right." In historical English law, the term carried two related but distinct uses:
1. In its general procedural sense, rectum rogare referred to the act of petitioning a court or judge to render justice — a formal demand that right be done in a matter before the tribunal.
2. In ecclesiastical and civil disabilities law, the term was applied specifically to the act of Roman Catholics (and historically, religious nonconformists more broadly) who formally petitioned for recognition of their rights despite their separation from the established Church of England. Black's traces this usage to Termes de la Ley, noting that while the phrase was initially extended to all who separated from the established church, in practice it became restricted to Roman Catholics.

Common Confusion
The two applications of rectum rogare — one broadly procedural, one tied to religious disability — can be conflated when reading historical sources without context. Rapalje & Lawrence give only the procedural meaning; Black's preserves both. A researcher encountering the term in an ecclesiastical or civil disabilities context should not assume the general procedural meaning applies, and vice versa. The religious-disability application is essentially obsolete and has no continuing legal force.

Why It Matters in Research
This term is almost exclusively encountered in early modern and pre-modern English legal materials. Its principal research relevance is historical rather than operational.
For researchers working in ecclesiastical law, recusancy law, or the history of civil disabilities imposed on Catholics and Protestant nonconformists, the term marks a formal procedural posture — a petitioner's assertion of right in the face of legal disadvantage rooted in religious nonconformity. Primary source materials from the sixteenth through eighteenth centuries are the most likely habitat.
For researchers in the history of common law procedure, the general sense of "petitioning for right" connects to the broader conceptual vocabulary of early common law, where formal demands for justice were ritualized and named. The phrase sits within a family of Latin procedural terms that governed the conduct of medieval and early modern litigation.
The term does not appear in modern American or English statutory or case law in any operative sense. A researcher finding it in a secondary source after the mid-nineteenth century is likely encountering either historical recapitulation or an antiquarian usage. The practical restriction to Roman Catholics noted by Black's reflects the progressive narrowing of recusancy law over time — broader nonconformist disabilities were largely resolved before Catholic emancipation, leaving Catholics as the principal class to whom the formal mechanics of rights-petitioning under disability remained relevant.
Researchers using digitized historical corpora should be alert to variant spellings and abbreviations common in Law Latin sources. The phrase may appear in anglicized paraphrase as well as in full Latin form.

Historical Dictionary Support
Rapalje & Lawrence provide only the core procedural meaning — to ask for right, to petition the judge — without reference to the ecclesiastical application. This is the foundational sense of the phrase and the one that would have been most familiar to practitioners consulting a general legal dictionary in the American context, where recusancy law had no direct application.
Black's Law Dictionary preserves both meanings and explicitly credits Termes de la Ley — the early English legal glossary attributed to various medieval and early modern hands — as the source for the ecclesiastical application. This citation is significant: it signals that the religious-disability usage was already being treated as learned historical material rather than live doctrine even at the time Black's was compiled. Black's editorial note that the term "was practically restricted to Roman Catholics" reflects the historical terminus of the recusancy framework rather than an enduring legal category.
Neither dictionary provides case authority or statutory grounding, which is consistent with the term's character as part of the Latin procedural vocabulary that was absorbed into and eventually superseded by the common law's developing English-language forms.
