Unlawful Assembly and Riot

Fundamentals of Criminal Law by Adam J. McKee

The common law traditionally defined unlawful assembly as the gathering of three or more individuals with the intention of committing a crime, or with the intent to carry out a lawful purpose through unlawful means, such as violence or intimidation. This definition emphasized the potential for public disturbance and the threat to peace and order.

A riot, as understood in common law, took this a step further. It involved a group of at least three individuals acting together in a violent and tumultuous manner, causing a disturbance of the peace. These definitions hinged on the collective intent and actions of the group, focusing on the potential or actual public disorder resulting from their conduct.

Modern Statutory Example

In the modern era, many jurisdictions have codified these offenses, often expanding or refining their definitions. For example, under California Penal Code Section 407 and 404, “unlawful assembly” is defined as the gathering of two or more people to do an unlawful act or to do a lawful act in a violent, boisterous, or tumultuous manner. A “riot,” under Section 405, involves two or more people, without legal authority, using force or violence, disturbing the public peace, or threatening to do so.

These statutes reflect a modern interpretation of the offenses, emphasizing the elements of violence, disturbance, and the threat to public peace. They also lower the threshold for the number of individuals involved, acknowledging that even smaller groups can pose a significant threat to public order. These laws often come with specified penalties and are used to manage and control public gatherings, protests, and demonstrations, balancing the right to assembly and free speech with the need to maintain public safety and order.

Classification and Punishment

The classification and punishment of offenses related to unlawful assembly and riot vary depending on the jurisdiction and the specific circumstances of each case. Generally, these offenses are classified based on the severity of the conduct and the extent of the threat or disturbance caused.

In many jurisdictions, unlawful assembly is classified as a misdemeanor. This classification is due to the nature of the offense, which typically involves assembling with an intent to commit a crime or to act in a disorderly manner, but may not always lead to actual violence or significant public disturbance. Punishments for unlawful assembly often include fines, community service, or short-term imprisonment.

On the other hand, riot is usually considered a more serious offense and can be classified as a felony in certain circumstances, particularly when it involves significant violence, property damage, or poses a substantial threat to public safety. The penalties for rioting are generally more severe than those for unlawful assembly and can include longer terms of imprisonment, larger fines, and a permanent criminal record.

Some statutes also provide enhanced penalties if the unlawful assembly or riot leads to injuries, significant property damage, or if weapons are used during the incident. Additionally, individuals who are found to be organizers or instigators of such events may face stricter punishments.

It is important to note that while these offenses are aimed at maintaining public order, enforcement is balanced against constitutional protections for freedom of assembly and speech. Thus, the application of these laws often involves careful consideration of the rights of individuals to gather and express themselves versus the need to prevent and manage public disturbances.
