unlawful assembly
C2Formal, Legal
Definition
Meaning
A gathering of three or more people with the intent to commit a crime or to carry out some act, lawful or unlawful, in a manner likely to cause a breach of the peace.
A specific common law offence, and a statutory offence in many jurisdictions, concerning a group meeting for a purpose deemed illegal by authorities, often associated with riot, disturbance, or sedition.
Linguistics
Semantic Notes
The term is highly legalistic and precise. It implies a collective intent to engage in disruptive or illegal activity, distinguishing it from a peaceful, lawful protest. The 'unlawful' element typically refers to the purpose or the manner of the assembly, not merely the act of gathering.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation as 'незаконное собрание', which is too broad. Russian 'несанкционированный митинг' (unauthorized rally) or 'массовые беспорядки' (mass disorder) may cover similar contexts but are not exact legal equivalents.
Common Mistakes
- Using it to describe any large, noisy crowd. It requires a specific unlawful intent or a likelihood of disturbance.
- Confusing it with 'riot'; unlawful assembly is often a precursor or a lesser included offence.
