The California legislature passed the Gun Violence Restraining Order (GRVO) into law in 2014 following a shooting in Isla Vista, CA, that left seven people including the shooter dead. Prior to the shooting, the shooter’s mother noticed he was behaving dangerously and asked law enforcement to intervene, but she was told that since her son was an adult and had not committed a crime, there was nothing they could do. California’s law went into effect on January 1, 2016.

A Gun Violence Restraining Order (GVRO) is a civil order that temporarily prohibits an individual who poses a significant danger of causing injury to self or others from purchasing or possessing any firearms or ammunition.1

Under California law, law enforcement, immediate family members, roommates, persons in a dating relationship with the respondent, people who share a child in common2, employers, co-workers3, and employees and teachers at a secondary or postsecondary school4 that the respondent has attended in the last six months, are authorized to petition for a GVRO.

There are three types of GVROs: temporary emergency GVROs, ex parte GVROs, and GVROs After Hearing. Law enforcement may request a temporary emergency GVRO over the phone outside normal court hours.5 Law enforcement, immediate family members (including a spouse, whether by marriage or not, domestic partner, parent, child, any person related by consanguinity or affinity within the second degree), roommates, dating partners, people who share a child in common, employers, co-workers, and employees and teachers at a secondary or postsecondary school that the respondent has attended in the last six months, may petition for a temporary GVRO ex parte during court hours. A temporary emergency GVRO and an ex parte GVRO remain in effect until a hearing for a GVRO After Hearing, but no longer than 21 days, when both the petitioner and respondent may address the court. A GVRO After Hearing lasts between one and five years and may be terminated prior to its expiration or renewed through court processes defined in the law.

California’s GVRO law includes ex parte GVROs issued by a judicial officer; a hearing where the respondent is provided notice and an opportunity to participate6; the respondent’s right to counsel (at no expense to the government); and the requirement of substantial and credible evidence (e.g. the enumerated factors the judicial officer must consider) to issue a GVRO.

The law was updated on September 26, 2023, to allow a court to consider evidence of acquisition of body armor when determining whether grounds for a GVRO exist.7

The law was updated again on September 24, 2024 to allow a court to consider, among other things, threats or acts of violence towards another individual, group, or location within the last 6 months; the unlawful and reckless use, display, or brandishing of a firearm indicating an increased risk for violence or actual threat of violence by the subject of the petition; recent acquisition or attempted acquisition of weapons; evidence of stalking; evidence of cruelty to animals; evidence of intentional damage or destruction of personal property for the purposes of intimidation; evidence of the respondent’s threats of violence to advance a political objective when deciding whether to grant a GVRO. The same law authorizes the court to additionally consider violations of comparable firearm-prohibiting criminal convictions or protective orders issued by out-of-state courts.8
