Definition
A Latin term from old legal practice meaning to stop up or block. It appears in early English pleading and procedural records to describe the physical or legal obstruction of something — typically a passage, watercourse, or right of way. The term carried a literal sense of plugging or stopping, and appears most often in conjunction with *obstruxit* (to obstruct) as a paired formula: *obstupavit et obstruxit* — stopped and obstructed.
Why It Matters in Research
This term is purely a relic of Latin pleading forms used in English common law practice, primarily in the 17th century and earlier. Researchers encountering it will almost certainly do so in the context of historical case reports or transcribed writs rather than any living legal doctrine. The paired phrase *obstupavit et obstruxit* functions as a doublet — a common drafting habit in medieval and early modern legal Latin where two near-synonymous terms were yoked together for emphasis or completeness. Understanding that both words mean roughly the same thing (to stop, to block, to obstruct) prevents misreading the phrase as describing two distinct acts.
The term does not survive in modern legal usage. Any researcher tracing nuisance doctrine, riparian rights, or right-of-way disputes into early modern English case law may encounter it in the original reports. It is a language artifact, not a substantive legal concept with independent doctrinal weight.
Historical Dictionary Support
Burrill's Law Dictionary is the sole shelf source to treat this term, and its entry is brief: it identifies *obstupare* as Latin, locates it in old practice, defines it as "to stop up," and supplies the phrase *obstupavit et obstruxit* with three reporter citations — 1 Ld. Raym. 452, 3 Leon. 13, and 1 Show. 252. These citations point to Lord Raymond's Reports, Leonard's Reports, and Shower's Reports respectively — all English case reporters from the late 17th century, confirming the term's period of active use.
No other standard historical law dictionary in the Law Mind corpus — not Black's, not Bouvier's, not Jacob's — appears to have treated *obstupare* as a term warranting its own entry. This is consistent with its status as operational pleading Latin rather than a term of art with substantive legal meaning. Burrill's broader coverage of Latin terms from old practice makes it the natural home for an entry like this.
