Disturbing a Public Meeting or Assembly
California Penal Code 403 PC

California Penal Code 403 PC provides that "Every person who, without authority of law, willfully disturbs or breaks up any assembly or meeting that is not unlawful in its character...is guilty of a misdemeanor."

Here are examples of "disturbing a meeting" that would likely be prosecuted:

  • Protesting tuition hikes, a group of UC Berkeley students brings a "boombox" and blares loud music outside the chancellor's office during a meeting he's having with faculty
  • Protesters at a prayer vigil begin chanting loudly, making it impossible for the prayer services to go on
What About Freedom of Speech?

Penal Code 403 has the potential to infringe on peoples' First Amendment right to freedom of speech and freedom to assemble peacefully. It also gives law enforcement enormous power and discretion to decide that certain forms of protest are illegal.

Therefore courts have said that it's only the crime of disturbing a meeting if the defendant deliberately and substantially impairs the function of the meeting. Also, the nature of the disturbance must be in the defendant's behavior, not his message.

Whether it's a crime or a permissible exercise of free speech depends on what is customary for the type of meeting in question. As the California Supreme Court explained:

In applying these standards, the nature of a meeting necessarily plays a major role....The customs and usages at political conventions may countenance prolonged, raucous, boisterous demonstrations as an accepted element of the meeting process; similar behavior would violate the customs and usages of a church service. Audience participation may be enthusiastically welcomed at a bonfire football rally or an athletic contest, but considered taboo at a solemn ceremony of a fraternal order. Explicit rules governing the time and place of permitted nonviolent expressions...may in some circumstances fix the limits of permissible conduct.1

The California Jury Instruction for Penal Code 403 lays out what the three things the prosecution must prove if a case goes to trial:

The defendant is charged [in Count ] with (disturbing/ [or] breaking up) a public meeting [in violation of Penal Code section 403].

To prove that the defendant is guilty of this crime, the People must prove that:

1 The defendant intentionally committed acts that violated (implicit customs or usages of/ [or] explicit rules for governing) a public meeting;

2 The defendant knew or reasonably should have known that (his/her) acts violated those (customs[,]/ [or] usages[,]/ [or] rules);

AND

3 The defendant's acts substantially [and unlawfully] interfered with the conduct of the meeting.

You may not find the defendant guilty of this crime unless you find that the defendant's acts themselves, not the message or expressive content of the acts, substantially interfered with the conduct of the meeting.

[When deciding whether the defendant knew or reasonably should have known that (his/her) acts violated the (implicit customs or usages of/ [or] explicit rules for governing) the meeting, you may consider whether someone warned or requested the defendant to stop (his/her) activities.] 2
Penalties, Punishment and Sentencing for Disturbing
a Meeting

Penal Code 403 is a misdemeanor in California law. As such, it carries a maximum sentence of up to six months of county jail. However, judges have discretion to grant probation with little or no actual jail time. The exact sentence in a given case depends on the circumstances of the offense and the defendant's prior criminal record, if any.

Related Crime: Penal Code 302 - Disturbing a Religious Meeting

Penal Code 302, California's disturbing a religious meeting law, prohibits one from disturbing a meeting comprised of religious worship. The statute is analogous to Penal Code 403, except that it carries a one-year maximum sentence (whereas Penal Code 403 only carries a six month maximum). 3 The harsher sentence reflects the public policy interest in protecting the sanctity of religious meetings.
