Unlawful assembly is a legal term to describe a group of people with the mutual intent of deliberate disturbance of the peace. If the group is about to start an act of disturbance, it is termed a rout; if the disturbance is commenced, it is then termed a riot. In England, the offence was abolished in 1986, but it exists in other countries.

Canada
Under Part II of the Canadian Criminal Code, Unlawful Assemblies and Riots is when the assembly of three or more people who cause fear and on reasonable grounds disturb peace in the neighborhood is against the law.
England
By the 19th century, unlawful assembly, a term used in English law, described a gathering of three or more people with intent to commit a crime by force, or to carry out a common purpose, in such a manner or in such circumstances as would in the opinion of firm and rational men endanger the public peace or create fear of immediate danger to the tranquillity of the neighborhood. A reform commission in 1879 believed that what underlay the first on-point legislation of 1328, outlining when such a crime was recognised nationally was certain landed proprietors at loggerheads employing a band of violent armed retainers, above the traditional manorial bailiffs. In the Year Book, a legal text, of the third year of Henry VII's reign, assemblies were expressed as not punishable unless in terrorem: populi domini regis, a threat to the people, God or the King. In 1882 it was ruled, on balance, an unlawful assembly would need to be more than participants knowing beforehand of likely formal opposition and the mere prospect of a breach of the peace; by this date a quiltwork of cases had identified certain rights to orderly, lawful protest. All people may, and must if called upon to do so, assist in dispersing an unlawful assembly. An assembly which was lawful could not be rendered unlawful by proclamation unless it were one authorized by statute. Cementing the English Bill of Rights 1689 banning private armies, meetings for training or drilling, or military movements, were from 1820 unlawful assemblies unless held under lawful authority from the Crown, the Lord-lieutenant, or two justices of the peace. An unlawful assembly which has made a motion towards its common purpose was termed a rout, if it carried out all or part of its end purpose, e.g., begin to demolish an enclosure, it became a riot. All three offences were misdemeanors in English law, punishable by fine and imprisonment. The first of these three offences was abolished by the Public Order Act 1986 for two parts of the UK, the most recent major reform of public order offences, the other two parts having similar legislation. The common law as to unlawful assembly extended to Ireland, subject to special legislation. The law of Scotland included unlawful assembly under the same head as rioting.

India
Section 144 of the Criminal Procedure Code of 1973 empowers an executive magistrate to issue orders in urgent cases of nuisance or apprehended danger. Though the scope of Section 144 is wider, it is often used to prohibit assembly of one or more persons when unrest is anticipated. Section 129 of the CrPC grants Executive Magistrates and Police officers in charge of a police station and above the power to order dispersal of, disperse and cause to be dispersed any unlawful assembly. Section 130 authorizes an Executive Magistrate to obtain the aid of the Armed Forces to disperse any such assembly, and Section 131 grants any Gazetted Officer of the Armed Forces the power to use his troops to disperse a manifestly dangerous assembly even without command from a Magistrate. The definition of 'unlawful assembly', according to Indian law, is laid down in Section 141 of the Indian Penal Code. According to this section, an assembly of five or more persons becomes unlawful when its purpose is or becomes:
To overawe by criminal force, or show of criminal force, the Central or any State Government or Parliament or the Legislature of any State, or any public servant in the exercise of the lawful power of such public servant;
To resist the execution of any law, or of any legal process;
To commit any mischief or criminal trespass, or other offence;
By means of criminal force, or show of criminal force, to any person, to take or obtain possession of any property, or to deprive any person of the enjoyment of a right of way, or of the use of water or other incorporeal right of which he is in possession or enjoyment, or to enforce any right or supposed right;
By means of criminal force, or show of criminal force, to compel any person to do what he is not legally bound to do, or to omit to do what he is legally entitled to do.
Section 146 defines 'rioting' is defined as the offence every member of an unlawful assembly commits, when that assembly or any member of such assembly uses force or violence in pursuit of their common intent. According to Sections 141-149 of the IPC, the maximum punishment for engaging in rioting is rigorous imprisonment for 3 years and/or fine. Every member of an unlawful assembly can be held responsible for a crime committed by the group. Obstructing an officer trying to disperse an unlawful assembly may attract further punishment. In about 1861, Officer Raj-Ratna E.F. Deboo IPS was the designer and architect of section 144, which reduced overall crime in that time in the state of Baroda. He was recognized for his initiative and awarded a gold medal by the Maharaja Gaekwad of Baroda for putting Section 144 in place and reducing overall crime.
