VEXARI

Definition

A Latin term meaning "to be harassed, vexed, or annoyed; to be prosecuted." In legal usage, vexari appears almost exclusively as a component of the maxim Nemo debet bis vexari pro una et eadem causa — "no one ought to be twice prosecuted for one and the same cause." The term does not function as a standalone doctrine but as a verbal element within this foundational principle of double jeopardy law. Its legal significance is entirely dependent on the maxim it anchors.

Common Confusion

Anderson's Dictionary of Law entry reproduced under this heading in the source material concerns VEST, not VEXARI — an apparent indexing or alphabetical error in that source. Researchers consulting Anderson's for vexari will find misdirected content and should treat that entry as non-responsive. The Black's editions are the controlling historical dictionary sources for this term.

Why It Matters in Research

Vexari is a research term, not a operative legal term. A researcher encountering it in a primary source — a pleading, a treatise, a judicial opinion — should treat it as a signal to pursue the bis vexari maxim and its doctrinal descendants rather than the Latin word itself. The maxim Nemo debet bis vexari is the common law ancestor of modern double jeopardy protections. Researchers working in historical materials, particularly pre-twentieth century English and American sources, will encounter the maxim invoked as the authoritative basis for what modern lawyers would frame as a Fifth Amendment or autrefois acquit / autrefois convict argument. The terminology shifts across time: earlier sources use the Latin maxim; mid-period sources may cite the maxim alongside English common law authority; modern sources translate the principle into constitutional or statutory double jeopardy language entirely. The underlying concept is continuous even when the vocabulary is not. Jurisdictional divergence matters here. In English common law and its early American reception, the bis vexari principle operated as a common law rule enforced through the pleas of autrefois acquit and autrefois convict. In American constitutional law, the same principle was absorbed into the Double Jeopardy Clause of the Fifth Amendment, with its own body of case law defining what constitutes "the same offence." Researchers should not assume that historical bis vexari doctrine maps cleanly onto modern American double jeopardy jurisprudence — the scope, the triggers, and the procedural mechanics differ. For corpus researchers using Law Mind: vexari will appear in Latin-rich common law texts, early American legal treatises, and historical pleading manuals. Its presence is a reliable marker of double jeopardy context. Cross-referencing against entries for double jeopardy, autrefois acquit, autrefois convict, and the related maxim nemo bis punitur pro eodem delicto (no one is punished twice for the same offense) will build out the full doctrinal picture.

Historical Dictionary Support

The Black's first and second edition entries are in substantive agreement: vexari means to be harassed, vexed, or annoyed, with "prosecuted" offered as the operative legal gloss. Both editions present the term through the lens of the Nemo debet bis vexari maxim, confirming that the word carries no independent legal weight outside that context. The second edition reproduces the maxim with a minor typographical variant (verari for vexari), which is a transcription artifact rather than a meaningful textual divergence. Neither Black's edition nor the Anderson's entry (which, as noted, misaddresses the term entirely) offers historical depth on the development of the bis vexari principle itself. Researchers seeking the doctrinal history of the maxim must look beyond dictionary sources to treatises such as Coke's Institutes and Blackstone's Commentaries, both of which address the common law foundations of double jeopardy protection. The Black's first edition cross-references Vexata Quaestio in the same passage — a related Latin term meaning a vexed or unsettled question — which is editorially proximate but doctrinally distinct.

Jurisdictional Note

The bis vexari maxim originated in English common law and carried into early American jurisprudence as a common law protection. In the United States, the principle is now primarily governed by the Fifth Amendment's Double Jeopardy Clause and its state constitutional equivalents. Researchers working in English or pre-constitutional American materials should apply the common law framework; those working in modern American materials should apply constitutional double jeopardy doctrine.
