Definition
A Scots law term describing the unlawful gathering of persons for violent or illegal purposes, where the gathering results in injury to persons or property, or causes terror and alarm to the surrounding community. Although the phrase "mobbing and rioting" is conventional and the two words almost always appear together in Scottish legal usage, they are technically distinct concepts that may be employed separately.
Mobbing refers to the conduct of the assembled group as a collective — the act of gathering unlawfully with a common violent purpose. Rioting describes the active execution of that purpose through violence or intimidation. Together, the compound term captures both the formation of the unlawful assembly and the violent acts that flow from it.
This is a term of Scots criminal law and has no direct equivalent as a compound phrase in English law, American law, or other common law systems, which address the same conduct through the separate offenses of riot, unlawful assembly, and affray.
Common Language
Modern common usage (Wiktionary): "Mobbing" in contemporary English describes a form of workplace harassment or bullying by a group; in animal behavior, it refers to collective harassment of a predator. "Rioting" refers to violent public disorder by a crowd.
Historical common usage (Webster's 1913): A "mob" was defined as a disorderly crowd; a riotous assembly. "Riot" carried a similar sense of tumultuous public disorder.
The gap here is significant in two directions. First, "mobbing" in modern common English has migrated almost entirely toward workplace harassment, which bears no relationship to its legal meaning in Scots law. Second, the compound phrase "mobbing and rioting" as a unified legal term of art is invisible to readers familiar only with common English or English/American legal vocabulary, where riot and unlawful assembly are treated as entirely separate offenses with distinct elements.
Common Confusion
Researchers should not conflate "mobbing and rioting" with the English law offense of riot, the American common law or statutory offense of riot, or the related offense of unlawful assembly. These are parallel concepts, but they arise from different legal traditions and carry different formal elements. English riot law developed through statutes such as the Riot Act 1714, whereas Scots law developed "mobbing and rioting" as a distinct nomen juris through the common law of Scotland. The two systems diverged in how they treated collective criminal liability, the number of persons required, and the mental element of the assembly.
Additionally, do not confuse "mobbing" in this legal context with its modern usage in employment law and harassment jurisprudence, which is an entirely unrelated concept.
Why It Matters in Research
The primary research trap with this term is its jurisdictional specificity. It is a term of Scots law, and its appearance in English-language legal dictionaries — including both editions of Black's and Bouvier's — reflects those dictionaries' effort to catalog Scottish legal terminology rather than to describe English or American law. A researcher who encounters "mobbing and rioting" in a historical American or English source should treat it as a borrowing or an explanatory reference, not as applicable local doctrine.
The compound phrase has a fixed conventional form. In Scots legal materials, you will almost always find the two words together. Searching historical Scottish sources for "riot" or "mob" alone may surface relevant cases, but the authoritative charge in Scottish indictments was typically framed as "mobbing and rioting" as a single offense. Researchers working in digitized historical Scottish court records should search both the compound and the component terms.
The phrase also raises collective criminal liability questions that are live in modern legal scholarship. Scots law treated the mob as collectively responsible for acts committed by individual members during the mobbing — a doctrine with implications for modern debates about joint enterprise and conspiracy liability. Researchers tracing the intellectual history of collective criminal responsibility should note that Scots sources on mobbing and rioting may predate and inform English and American treatments of the same problem.
Because the term appears almost identically across all three historical dictionaries in the Law Mind corpus, there is little divergence among sources — but equally little elaboration. Researchers needing substantive doctrine will need to go beyond dictionary sources to Scottish institutional writers and case law.
Historical Dictionary Support
Black's Law Dictionary (both editions) and Bouvier's Law Dictionary present nearly identical entries, all limiting the definition to Scots law and noting the conventional pairing alongside the theoretical distinctness of the two terms. No edition provides the specific elements of either mobbing or rioting as separately defined, nor do they explain what threshold of persons, what degree of violence, or what mental state was required under Scots law.
The uniformity across sources is itself informative: it reflects the fact that these dictionaries were drawing on the same Scottish legal authorities rather than developing independent analysis. None of the three historical dictionaries addresses the English Riot Act, American riot statutes, or the relationship between Scots doctrine and English common law — suggesting that the editors treated this as a foreign law entry rather than one with operational relevance to their primary audience.
What the historical dictionaries miss: no discussion of the collective liability doctrine that was central to Scots mobbing cases, no treatment of how courts distinguished mere unlawful assembly from a completed mobbing, and no engagement with the procedural question of how the charge was framed in Scottish indictments.
Jurisdictional Note
This term is exclusively a term of Scots law. English law, American law, and other common law jurisdictions address the same underlying conduct through separate offenses — riot, unlawful assembly, affray, and related charges — each with their own statutory or common law definitions. Researchers working in Scottish legal history will encounter this term regularly; those working in English or American legal history should treat any reference to it as a comparative or explanatory notation rather than applicable authority.
