When people talk about disorderly conduct, if they’re in California, the behavior they are describing is actually considered disturbing the peace. There are three types of behaviors covered by California Penal Code 415 (PC), these include playing excessively loud music, getting in a fight in public, or even using certain words. While these crimes may seem relatively minor, they can still be charged as misdemeanors in Vista, which means they will stay on your criminal record, which could dramatically impact your future.
What is Disorderly Conduct Under 415 (PC)?
California Penal Code Section 415 (PC) states that it is against the law to:
- Fight another person in a public place
- Challenge someone to fight while in a public place
- Willfully and maliciously disturb another person with loud and unreasonable noise
- Use offensive words in a public place that are inherently likely to provoke an immediate violent reaction from another person
One thing few people understand about these laws is that when the law says a “public place,” it’s not just referring to a government-owned area such as a park or beach, but essentially any place outside of a private home. Even if a mall, restaurant or bar is privately owned, the property is still considered public because it is open to the general public. Even being inside your vehicle on a public road or parking lot is considered being out in public.
Unlawful Fighting in Public
For prosecutors to secure a conviction related to disturbing the peace by fighting or challenging someone to a fight in a public place, they must show that the defendant willfully and unlawfully fought or challenged another person to a fight and that they were in a public place at the time.
One of the best ways to fight this type of disorderly conduct is to claim you were acting in self defense. This defense will only be successful if you believed:
- you or another person was in danger of immediate violence
- the only way to protect you or the other person was to use force
- you did not use excessive force
Unreasonable Noise
Maliciously and willfully disturbing another person with loud noises is another violation of 415 (PC). In order for the prosecution to prove your guilt in these cases, they must show you played loud music, screamed, or otherwise made loud and unreasonable noise, knowing you were doing something wrongful or were acting with the intent to annoy someone else. “Disturbing” someone under this law means that the noise either caused a clear and present danger of violence or the noise was used to disrupt lawful activities, not as a means of communication.
In other words, if you used a megaphone at a rally to help communicate to everyone in the crowd, you didn’t break the law, even if it annoyed people of opposing views. On the other hand, if you mumbled nonsense on the megaphone just to prevent the other side from being able to talk to one another, that means you were acting maliciously to disrupt their lawful right to protest.
Using Offensive Words
Yes, in America we have the right to free speech, but if you use offensive language that is likely to result in a violent response, you can be charged with a crime. Essentially if you use “fighting words,” you broke the law. It’s important to recognize that you didn’t need to actually succeed in causing a violent reaction, just that you used language likely to do so.
This is one situation where your criminal defense attorney is likely to argue that you were exercising your First Amendment right to free speech, even if it actually disturbed another person enough to start a fight. This defense will not work in every situation, but it can be very effective as Americans are particularly protective of their right to free speech.
Penalties for Disturbing the Peace
Depending on your criminal record and the specifics of the case, this crime may be charged as a misdemeanor or infraction. If it is charged as an infraction, you will only face a fine and the charge will stay off of your record. On other other hand, when the crime is charged as a misdemeanor, you can face a $400 fine, 90 days in the county jail and the charge will end up on your record so it can be held against you when you apply for jobs, housing or if you are charged with another offense in the future.
Local Noise Ordinances in Vista
Aside from the state’s disturbing peace laws, counties and cities may have their own noise restrictions as well. For example, under Vista Municipal Code 8.32, the following activities are misdemeanor offenses:
- Noises that are plainly audible from 50 feet away between the hours of 10 PM and 7 AM (specific decibel levels vary between 45 and 70, based on area)
- Music amplifiers that are loud enough to cause vibrations 50 feet away (Depending on the area, acceptable decibel levels may be between 50 and 70)
Each day the noise continues counts as a distinct offense under the law. Penalties include up to 6 months in jail and a $1,000 fine. Additionally, those convicted are subject to the seizure and destruction of their noise-making devices.
Disturbing a Public Assembly 403 (PC)
A similar but distinct crime is disturbing a public meeting or assembly, which occurs when someone willfully and illegally breaks up or disturbs a legal meeting or assembly. To be convicted, the prosecution must prove the individuals acted intentionally and knew their behavior would disturb the meeting, and the activity must unlawfully interfere with the session.
So, for example, if someone smashed the microphone to interrupt a town hall held by Vista Representative Mike Levin or Escondido Representative Darrell Issa, they would be breaking the law. However, if they asked a policy question they knew would upset him and possibly make him leave, they would only be utilizing their freedom of speech and would not be violating the law.
This offense is a misdemeanor, punishable by no more than 6 months in jail and $1,000 in fines.
Related Criminal Charges
Those accused of disorderly conduct may also face other criminal charges as well. If they attempted to fight or challenge someone to a fight, they could face violent crimes charges such as assault with a deadly weapon, making criminal threats, assault, or battery. If the two parties involved are married, dating, or otherwise intimate, the aggressor could also face domestic violence charges.
If the incident occurred during a protest, other common charges include rioting, looting, unlawful assembly, resisting arrest, lynching, or failure to disperse. In these cases, it is common for the police to overreact to having to monitor a large number of people all at once and one of the best defenses is to claim that you were only engaged in lawful activities and there is insufficient proof to show that you acted in a violent manner or otherwise caused a disturbance.
It’s worth knowing that disturbing the peace is commonly thought of as the lowest level of misdemeanors, as it is essentially just the crime of making loud noise, so it is actually not commonly charged as a misdemeanor but instead used as reduced charge for more serious misdemeanors in plea bargains. For example a battery charge results in the prohibition of gun possession, but disturbing the peace doesn’t have that consequence. It is also capable of being made an infraction even after a conviction. In fact, this is is the go-to generic misdemeanor when the prosecutors won’t dismiss all charges.
