National Extreme Risk Protection Order (ERPO) Resource Center

A Tool to Save Lives

An Extreme Risk Protection Order (ERPO)1 is a civil court order that temporarily restricts firearm access for an individual who is behaving dangerously or presents a high risk of harm to self or others.

A Resource for Implementers

The Johns Hopkins Center for Gun Violence Solutions, in collaboration with the U.S. Department of Justice, Bureau of Justice Assistance (BJA), established the National ERPO Resource Center (ERC) in 2023.

1 ERPOs are also referred to as red flag laws, among other names. For example, Delaware’s ERPO law is called a Lethal Violence Protection Order and California’s ERPO law is called a Gun Violence Restraining Order.

What are Extreme Risk Protection Orders?

As of March 2024, 21 states and the District of Columbia have enacted ERPO laws. Though the names of these laws and the laws themselves vary by state, the process is similar for most petitioners. In all states, ERPOs are civil, not criminal, court orders. However, violation of an ERPO law may be a criminal offense depending on state law.

ERPOs temporarily prohibit a person from possessing or purchasing firearms and provide a process for the removal of firearms already in the person’s possession. The possession of a firearm is not required for an individual to be an ERPO respondent. An ERPO also temporarily prevents someone who is behaving dangerously or at risk of committing violence from purchasing and possessing firearms.

ERPO laws are based on domestic violence protection order laws, which have been in place in all 50 states for decades and are a well-established tool for protecting people experiencing intimate partner violence.

Even in states where ERPO is law, implementation varies within states and across states, signaling the need for close attention to implementation.

Several jurisdictions have established specialized ERPO teams to handle ERPO petitions, service, firearm dispossession, and the return of firearms.

ERPO Implementers

  1. Illustration of a law enforcement badge Law Enforcement In every state with an ERPO law, law enforcement may petition the court to issue an ERPO to temporarily restrict an individual’s access to firearms when they are behaving dangerously or when they are at an elevated risk of harm to self or others. In most states, law enforcement are also responsible for serving the ERPO petition and removing the firearms from ERPO respondents’ possession.
  2. Illustration of a gavel Judicial Officers Judges, magistrates, commissioners, and other judicial officers weigh the evidence and determine whether to grant or deny the petition for an ERPO.
  3. Illustration of two hands shaking Family and Household Members In 16 states, family and household members are eligible to petition for ERPOs when they are concerned about their family or household members accessing firearms. In all states, family members can play a critical role in ensuring the safety of individuals whose access to firearms may pose a threat to themselves or others.
  4. Illustration of a stethoscope Clinicians The definition of clinician varies somewhat by state statutes, but typically includes physicians, licensed clinical social workers, and credentialed therapists. In some states, clinicians may petition for an ERPO for a patient that is behaving dangerously or at an elevated risk of harm to self or others. In other states, clinicians can work with law enforcement to initiate an ERPO.
  5. Illustration of a briefcase Attorneys Attorneys present the evidence to the court, often on behalf of law enforcement petitioners. Respondents also have the right to counsel, at no cost to the government.
  6. Illustration of a clipboard and pen Social Service Providers Social service providers, including social workers, advocates, and individuals working at community response organizations, play an important role in helping respondents and their families navigate the system, connect to other resources, such as domestic violence or mental health programs and services, and, in some states, even file for an ERPO.

Due Process Protections

The Bipartisan Safer Communities Act requires that ERPO programs funded through the Byrne SCIP program include the following due process rights:

  • Notice;
  • An in-person hearing;
  • An unbiased adjudicator;
  • Know opposing evidence;
  • Present evidence;
  • Confront adverse witnesses;
  • Be represented by counsel at no expense to the government;
  • Heightened evidentiary standards and proof which mean not less than the protections afforded to a similarly situated litigant;
  • Penalties for abuse of the program.

The ERC closely monitors ERPO cases and rulings on ERPO and due process to ensure that it is aware of any changes in the law that may impact ERPO implementation.
