Definition
A Latin maxim from the civil law tradition meaning "to run by its own force." The phrase describes a legal proceeding that advances to its natural conclusion without interruption, stay, or external impediment. A suit that ran marte suo decurrere was one that proceeded under its own momentum — no party intervened to arrest it, no court order suspended it, and no procedural obstacle prevented it from reaching judgment.
The concept operates as descriptive shorthand for the unobstructed course of litigation: once set in motion, the suit carried itself through to its end.

Why It Matters in Research
This term rarely surfaces in modern Anglo-American legal materials, but appears with some regularity in treatises, digests, and commentaries drawing on Roman or civil law foundations — particularly texts dealing with the suspension of proceedings, stays of action, or the effect of procedural events on the progress of a suit.
Researchers encountering the phrase in historical sources should treat it as a signal that the surrounding text is analyzing what happens when a proceeding is interrupted — by the death of a party, a plea in abatement, a writ of error, or similar event — and contrasting that interrupted state with the unimpeded norm. The phrase marks the baseline: a suit running marte suo decurrere is the untroubled default against which impediments are measured.
The term is unlikely to appear in common law case reporters with frequency, but may be found in early American and English equity materials, ecclesiastical law texts, and admiralty sources where civil law influence was strong. It also appears in legal dictionaries as a cross-reference anchor when editors were cataloguing Latin maxims governing procedural flow.
When using Law Mind's corpus to trace this term, search not only for the Latin phrase directly, but for its conceptual context: discussions of stays, abatements, suspended proceedings, and the effect of appeals or writs on the running of a suit. The term's natural habitat is the surrounding doctrinal argument, not standalone citation.
One research trap: the phrase can be easy to misread in older typeset materials where "marte" appears as a proper noun (as in the Roman god Mars), leading to confusion about whether the text is using the phrase technically or metaphorically. In legal usage it is always technical, always procedural, and always refers to the self-propelled progress of a suit.

Historical Dictionary Support
Black's Law Dictionary (1st and 2nd editions) and Burrill's Law Dictionary are in close agreement on this term, all three providing near-identical definitions: "to run by its own force," applied in the civil law to a suit proceeding to its end without impediment. The definitional consensus across these sources is unusually tight.
Both Black's editions and Burrill cite Calvin — a reference to Johannes Calvinus (Jean Calvin the jurist, not the reformer), whose *Lexicon Juridicum* was a major source for Latin legal maxims in this period. Burrill adds a citation to Brissonius (*De Verbis Juris*), another standard authority on civil law terminology. Neither source elaborates beyond the single-sentence definition, which suggests the phrase was treated as self-evident to a readership fluent in civil law Latin.
What the historical dictionaries do not supply: any sustained analysis of the doctrine the phrase embeds, any illustration of how the concept functioned in specific procedural contexts, or any tracing of the term into English or American cases. Researchers should not expect these sources to do that work — they are cataloguing the phrase, not expounding it. The substantive research must be pursued through the primary civil law authorities and their commentators.

Jurisdictional Note
This is a civil law term with no direct common law parallel and no recognized modern statutory or regulatory usage in American or English law. It is most relevant to research involving admiralty, equity, ecclesiastical, and comparative law contexts where civil law procedure was either applied directly or used as an analytical framework.
