Definition
An obsolete legal term appearing in old English records meaning a net, gin, or snare — a device used to catch animals or fish. The term had no developed doctrinal significance; it appears primarily in archaic grants, forest records, and manorial documents where the right to use or possess such devices was a legally recognized entitlement or a regulated privilege.
Common Language
Modern common usage (Wiktionary): LAAS is an initialism for Laboratory for Analysis and Architecture of Systems, a French research institution.
Historical common usage (Webster's 1913): An obsolete form of "lace," attributed to Chaucer.
Neither modern nor historical common usage tracks the legal meaning. The legal sense — a net, gin, or snare — is entirely distinct from both the textile association in Middle English and the modern institutional abbreviation. A researcher encountering LAAS in an old record should resist any association with these common forms.
Why It Matters in Research
LAAS is a term you are unlikely to encounter outside of medieval and early modern English records — specifically manorial rolls, forest court records, game law instruments, and grants touching on hunting or fishing rights. Its significance lies not in any legal doctrine but in what its presence signals: the document in question is dealing with the regulation of taking animals, likely in the context of forest law, free warren, or similar proprietary rights over game and fish.
Two research traps are worth noting. First, the term is rare enough that standard common law indexes and digests will not surface it; finding it requires working directly with the historical record or specialized paleographic aids. Second, a researcher unfamiliar with the term may misconstrue an archaic grant — for instance, a privilege to keep or use a "laas" would be a right to employ trapping devices, not a right to land or any modern analogue.
If researching the scope of historical hunting or fishing privileges in English law, LAAS connects directly to the broader framework of forest law, free warren grants, and the legal distinction between rights of chase, warren, and fishery. These surrounding concepts are far better documented in the historical sources and should anchor any serious research in this area.
Historical Dictionary Support
The three sources agree completely: LAAS means a net, gin, or snare. Black's first and second editions are nearly identical, with the second edition adding the qualifier "In old records," which is a useful confirmation that the term is archaic even by the standards of early American legal lexicography. Rapalje & Lawrence reproduce the same definition without elaboration, then immediately pivot to the entry for LABEL — a juxtaposition that reflects alphabetical coincidence rather than any conceptual link.
None of the historical dictionaries situate LAAS within a broader legal context or identify the body of law (forest law, game law) in which it operated. The sources treat it as a vocabulary item requiring translation rather than a concept requiring explanation. That minimalism is appropriate given the term's limited doctrinal footprint, but it leaves the researcher without guidance on where to look next.
Jurisdictional Note
LAAS as a legal term is a product of English law and has no documented equivalent in American legal usage. Researchers working in American sources will not encounter it. It is relevant only to English historical records, particularly pre-modern instruments.
