Definition
S law (also written Oswald's Law or the Law of Oswald) is a historical ecclesiastical enactment associated with Oswald, Bishop of Worcester, circa A.D. 964, by which married priests were ejected from their offices and replaced by monks. The law was part of the broader Benedictine reform movement in tenth-century England, which sought to impose monastic discipline on the English church and restore canonical celibacy requirements to the clergy.
The term appears in historical legal dictionaries as a curiosity of ecclesiastical law rather than as a term of art in active legal use. It has no operative meaning in modern law.

Common Confusion
The label "S law" is an artifact of abbreviated dictionary formatting — the full entry in Black's Supplemental reads "D'S LAW," which is itself a truncation or typographical corruption of "Oswald's Law." Researchers encountering this entry in scanned or digitized historical sources should be alert to OCR errors and printing artifacts that may obscure the complete term. The entry in Black's 2nd Edition Supplemental is one of several entries derived from Wharton's Law Lexicon and represents a category of historical ecclesiastical terms that were included for completeness rather than practical application.

Why It Matters in Research
This entry is primarily a bibliographic and indexing concern rather than a substantive legal research target. Several points for researchers:
First, the entry's mangled form in the Black's Supplemental ("D'S LAW") is almost certainly a digitization or typesetting artifact. Any researcher who encounters this string in a full-text search of historical legal dictionaries should cross-check against Wharton's Law Lexicon, which is the cited source, to recover the original form and context.
Second, researchers working on the history of English ecclesiastical law, clerical celibacy, or the tenth-century Benedictine reform will find this entry a pointer to a broader body of canon law and church history rather than a self-contained legal rule. The "law" in question is not a statute in any modern sense — it is closer to a bishop's ordinance or synodal decree operating within the pre-Conquest English church.
Third, because the Law Mind corpus includes both tax and business organization entries touching on "S" designations (S corporations, Regulation S), researchers should be aware that a search for "S law" or "S corporation law" will return entirely unrelated modern materials. The ecclesiastical meaning and the modern corporate/tax meaning share no lineage.

Historical Dictionary Support
The sole historical dictionary source for this entry is Black's Law Dictionary, 2nd Edition Supplemental, which itself cites Wharton. The entry is brief and descriptive, offering no legal analysis. Wharton's Law Lexicon (the likely origin) was a British legal dictionary that regularly incorporated ecclesiastical and historical curiosities alongside operative legal terms — a common feature of Victorian-era legal lexicography.
No other major historical legal dictionary (Bouvier, Burrill, Tomlin) appears to carry a corresponding entry for this term, which suggests it was never widely recognized as a term requiring standard definition and is best understood as a piece of ecclesiastical history preserved in dictionary form rather than a live legal concept.
The underlying historical event — Oswald of Worcester's reform of cathedral chapters — is well documented in ecclesiastical history. The reform was part of a coordinated movement involving Dunstan of Canterbury and Æthelwold of Winchester, operating under royal patronage of King Edgar. Its legal character derives from the intersection of royal and episcopal authority in pre-Conquest England, not from any freestanding legislative act.

Jurisdictional Note
This term has no jurisdictional relevance in any modern legal system. It refers exclusively to a historical episode in the English church and carries no force in contemporary English, American, or canon law.
