Civil gang injunctions are public nuisance actions that city attorneys or district attorneys bring in civil court to curb and disrupt gang-related criminal and noncriminal activities. Cities seek gang injunctions to intervene in, prevent and suppress gang activity in an affected neighborhood. Typically, gang injunctions not only prohibit already illegal activities but also impose restrictions on behavior of gang members that could lead to criminal acts, such as displaying gang colors or symbols or associating in public with other gang members. Gang injunctions provide critical advantages to police departments trying to disrupt gang activity, as well as to the residents living in areas afflicted by gangs. This article discusses the legal elements of civil gang injunctions and highlights the real-world experiences of two communities where this technique has been employed.

What Is a Civil Gang Injunction?

Gang injunctions are premised on the definition of “public nuisance.”1 A public nuisance is anything that is injurious or deleterious to one’s quiet enjoyment of life or property and affects the entire community, not just a few residents. The types of behavior that criminal street gangs engage in — including violence, graffiti and dealing narcotics — fall under the category of public nuisance. City attorneys and district attorneys have the ability to seek nuisance abatements through the courts.2

Civil gang injunctions are court orders prohibiting a particular criminal street gang from engaging in various activities. Typical prohibitions include:

  • Associating with other gang members;
  • Intimidation;
  • Recruiting for gangs;
  • Trespassing;
  • Possessing drugs, alcohol or firearms;
  • Drawing graffiti;
  • Fighting;
  • Making hand signals associated with gang membership, also known as “throwing” gang signs; and
  • Other similar activities.

It is also possible to seek curfews. Depending on the particular gang that is the subject of the injunction, other provisions may be included.

Gang injunctions target specified physical boundaries within which the gang operates. These target areas are often referred to as “Safety Zones.” Once the injunction is in place, each subsequent violation by a gang member of a properly enjoined gang becomes a contempt of court, for which the member can be jailed, fined or both. It is also possible to seek monetary damages through injunction if it can be shown that the gang is profiting from its nuisance-creating behavior.

Lessons Learned in Preparing Civil Gang Injunctions

Learn what a gang injunction is and is not, and learn the process from experienced individuals. This will help you understand the most direct path to obtaining an injunction, make fewer mistakes and avoid reinventing the wheel.

Figure out what the city wants to accomplish using a gang injunction when other police tactics won’t work. Gang injunctions seek extraordinary relief, and being able to explain this will be helpful when you go to court.

Determine who will write the “expert declaration” and which attorney will work on the lawsuit. Then plan how the workload will be divided. Some agencies use their City Attorney’s Office and others use the District Attorney’s Office. Any law enforcement agency considering seeking a gang injunction must have someone serve as the “expert.” This will be an experienced gang investigator who:

  • Can communicate effectively, both in writing and during expert testimony;
  • Has credibility with local courts as a gang expert;
  • Can work on the project exclusively for several months; and
  • Is willing and able to take on a massive project.

Gang injunctions are effective tools, but only if the gang engages in the behavior covered by California Civil Code 3479. If the gang expert cannot articulate how the gang’s behavior and activities fit the definition of a public nuisance, then the gang is not a good subject for a gang injunction. If they are a public nuisance, the next step is to define the nuisance.

Keep good statistics prior to pursuing a gang injunction. Your most persuasive arguments and testimony will come from a careful and easily understood presentation of the havoc that the gang is wreaking within the Safety Zone.

Develop your proposed Safety Zone using facts, not subjective ideas about where you think the gang is active. Once a spreadsheet is made using the statistics mentioned above, a geomapping application can be used to create a digital pin-map of where these events and activities took place. The Safety Zone should be established after this exercise because the boundary area where the gang commits its nuisances and crimes may likely be much larger than previously thought.

Writing the expert declaration requires a great deal of organization. If the law enforcement officer’s declarations of the individual case summaries are a methodical recitation of the events that the gang participates in, then the expert declaration is the “color commentary” that paints a picture for the court by describing what the gang does, how it does it and how its activities pose a nuisance.

Use photos. It is permissible to include photos in the expert declaration. A picture is worth a thousand words.

Compile a detailed accounting of gang members and their nuisance activities within the proposed Safety Zone. In order to sue the gang as an unincorporated association, the gang must be given notice so that it may defend itself if it so chooses. The chosen representatives’ documented behavior should be good examples of the gang’s nuisance activities.

Document gang members as active participants. The expert and attorney must be well versed not only in the documentation criteria but also in how it is known that the members are active participants in the gang.

Example: The City of Fairfield

The City of Fairfield Police Department gave Sergeant Jeff Osgood the task of researching and writing a gang injunction in 2008. During the previous 20 years, Fairfield had been experiencing consistently regular nuisance activity from its primary gangs, including violent assaults, murders, mass-attack beatings and drug dealing in their Safety Zone. The Fairfield Police Department had reservations about obtaining a gang injunction because of concerns that it wouldn’t work in Fairfield.

Support from the city’s administration, including the city’s management and political leaders, played a central role in the successful implementation of the gang injunction in Fairfield. The Police Department first conducted extensive research to learn what an injunction actually was and contacted several other agencies to learn from their mistakes. The department then reached out to city policy-makers to gain their support. In talking to other agencies, Sgt. Osgood learned that actively seeking such support is a key component of successfully laying the groundwork for the injunction effort; in some communities, a failure to do so had resulted in stakeholders becoming hostile toward the effort and actively opposing it.

Almost immediately upon issuing a preliminary gang injunction against one of the gangs, its activity was disrupted, and its members have rarely been seen together on the streets since. The overall result has been a dramatic drop in all activity from the gang as well as from its rival.

Example: The City of Oakland

In contrast to Fairfield, the intense media attention surrounding Oakland’s pursuit of gang injunctions against the North Side Oakland (NSO) gang, located in the city’s northwest area, and the Norteños, located in the city’s Fruitvale area, shows that the strategy is still controversial. Indeed, unlike Fairfield, Oakland’s gang injunction strategy did not enjoy unanimous and unfettered support from the city as a whole. It remains to be seen whether employing the gang injunction technique without unanimous support or full community buy-in is effective.

As with critiques of gang injunctions in general, the defendants in Oakland’s NSO and Norteños cases argued that gang injunctions violate due process rights, promote racial profiling and harassment, and divert funds better spent on social justice programs. These criticisms, however, have proved unavailing — at least in the first phase of these ongoing cases. Oakland has ensured that due process is respected by naming individual gang members, thus providing them an opportunity to speak up on their own behalf in court. In addition, no one will be enjoined without the court weighing in on the sufficiency of the city’s evidence.

Finally, the city is using resources that never would or could be diverted to social programs. The city has successfully obtained a preliminary injunction against the NSO gang and all individually named defendants, as well as the Norteños gang and the individually named defendants who were a part of the first phase of litigation. Because these cases are both ongoing and litigation is pending, it is premature to assess the impact of the preliminary injunctions. However, no individual subject to the preliminary injunctions appears to have violated any terms to date.

The Impact of Gang Injunctions

Current research bears out that carefully crafted gang injunctions can decrease gang-related criminal activity — at least in the short term. Studies and relevant literature show injunctions may:

  • Reduce the rates of certain crimes;
  • Reduce gang visibility;
  • Reduce resident intimidation and fear of gang confrontations;
  • Increase residents’ sense of control over their community; and
  • Provide an excuse for some members to get out of the gang.3

These latter effects are particularly critical to improving neighborhood dynamics and community safety.

While gang injunctions alone may not be enough to eliminate gang activity, they are a law enforcement tool that can crack the window of opportunity for change.4
