Unlawful Assembly Prosecutions
I. 🔍 What is Unlawful Assembly?
An Unlawful Assembly refers to a gathering of three or more people with the intent to carry out a common purpose that causes fear of disturbance or actual disturbance of the peace. Such assemblies can be prosecuted if they pose a threat to public order, safety, or property.
II. ⚖️ Legal Framework
Unlawful assembly is primarily governed by:
Public Order Act 1986, especially:

Section 12: Police powers to impose conditions on assemblies
Section 13: Offences related to failure to comply with conditions
Section 14: Police powers to prohibit public assemblies
