Unlawful Assembly - Penal Code 408 PC

Posted by Sam Israels | Jan 04, 2024

California Penal Code 408 PC is the statute making it a misdemeanor crime for someone to participate in an unlawful assembly, which is two or more people gathering to do something illegal or a violent lawful act.

Penal Code 408 PC - Unlawful Assembly in California
PC 408 makes it a crime for two or more to participate in an unlawful assembly for a violent act.

Related Penal Code 407 PC defines an unlawful assembly as “Whenever two or more persons assemble to do an unlawful act or do a lawful act in a violent, boisterous, or tumultuous manner, such assembly is an unlawful assembly.” PC 408 says, “Every person who participates in any rout or unlawful assembly is guilty of a misdemeanor.”

To convict you of unlawful assembly, a prosecutor must prove that you willfully participated, knew that the assembly was illegal, participated, and committed an act “willfully,” meaning it was on purpose.

Notably, when two or more people assemble to do a lawful act violently, it is not unlawful unless violence occurs or there is a clear and present danger of imminent violence.

Most people know that the First Amendment to the Constitution guarantees U.S. citizens the right to assemble peaceably. However, once a peaceful assembly turns violent, or there are criminal acts, it is considered a Penal Code 408 PC unlawful assembly.  

These laws are supposed to help maintain public order and safety by prohibiting people from committing illegal acts when they assemble, disturb the peace, or engage in behavior threatening public safety. Simply put, PC 408 makes it a crime for people to participate in an unlawful assembly, meaning two or more gatherings to do something illegal or a lawful act violently. 

What Is an Unlawful Assembly?

As noted, California Penal Code 407 PC defines an unlawful assembly as follows: 

  • Two or more people assembling to commit an unlawful act or
  • Two or more people assembling to commit a lawful act in a "violent, boisterous, or tumultuous manner."

Notably, these above definitions allow law enforcement to charge you with unlawful assembly even if you are not committing another crime while assembled with others.  

Suppose you lawfully assemble with others, but police consider it disruptive. In that case, you might still face criminal charges. Notably, however, when two or more people assemble for a violent act, it's not considered unlawful unless violence occurs or there is a clear and present danger of imminent violence.

Also notable is that you can still be charged with PC 408 unlawful assembly even if you did not commit a crime during the assembly but were participating with the group.

Suppose you participate in a lawful protest before a local station but start becoming boisterous and block traffic. In that case, you and others could be charged with violating PC 408.

What Must Be Proven for a Conviction?

To convict you of violating the unlawful assembly laws, the prosecution must prove, beyond a reasonable doubt, the following elements of the crime: 

  • You willingly participated in an assembly of two or more people,
  • The primary purpose of the assembly was to commit a crime, breach the peace, or engage in conduct likely resulting in disturbance of the peace or was a public safety threat.
