Definition
Latin. In old English law, a common street or road — a public thoroughfare open to general use. The term appears in medieval and early modern English legal records to describe a way over which the public held a right of passage, as distinguished from private roads or ways held by particular individuals or tenures.
Why It Matters in Research
Researchers encountering *communis strata* in pre-modern English legal sources should treat it as a term of art for public roads and thoroughfares, not merely a descriptive phrase. Its practical significance lies in how it bounded property rights, defined trespass, and established where public versus private obligations for maintenance fell. Medieval and early modern pleadings, local court rolls, and statutory materials will use this phrase where a modern document would say "public highway" or "public road."
The most important navigational point is the contested relationship between *communis strata* and *regia via*. Both terms describe public ways, but they are not self-evidently identical, and English courts and commentators debated whether they were synonymous. Burrill flags this argument directly, citing 10 Mod. 382, where the equivalence was contended. A researcher who treats the two terms as interchangeable without checking the specific source context risks misreading the scope of public rights being asserted or denied. In some contexts, *regia via* (the king's highway) carried a stronger implication of royal protection and Crown-backed public right, while *communis strata* emphasized the communal or common character of the way. Whether that distinction was legally operative in a given case or text requires careful reading.
The Statute of Marlborough (1267), cited by Burrill at chapter 15, is the statutory anchor for this term's appearance in formal legal materials. Researchers using the term as a finding aid in corpus searches should include variant spellings — *strata* alone, *via communis*, and *regia via* — to capture the full range of related source material, as Latin legal drafting was not always consistent in terminology across centuries or jurisdictions.
Historical Dictionary Support
Burrill's Law Dictionary provides the only substantive entry among the shelf sources. The entry is brief but precise: *communis strata* means a common street or road in old English law, citing the Statute of Marlborough and two reporters — 1 Strange 44 and 10 Modern 382. The most instructive detail Burrill preserves is the argument, made in the latter report, that *communis strata* is synonymous with *regia via*. Burrill neither endorses nor rejects this equivalence, presenting it as a contested proposition rather than settled doctrine — an appropriately cautious position given that courts appear to have used the terms in overlapping but not always interchangeable ways.
What historical dictionaries as a class do not capture well is the full texture of how *communis strata* functioned in local and manorial practice, where road obligations, boundary disputes, and rights of passage were litigated in courts that left records now accessible through archival rather than printed sources. Burrill's citation trail — the statute and the two reporters — covers the formal common law dimension; the broader practical dimension requires going to those primary sources directly.
Jurisdictional Note
*Communis strata* is a term of English law and appears in sources arising from English courts and statutes. It has no direct counterpart as a term of art in Scots law or early American legal practice, though the underlying concept of a public road is universal. Researchers working in colonial American materials will generally find the concept expressed in English rather than Latin by the eighteenth century.
