Federal law generally prohibits possession of firearms and ammunition by people who have been found by a court, board, commission, or other lawful authority to be a danger to themselves or others, or to lack “the mental capacity to contract or manage [their] own affairs,” as a result of their mental condition or illness.¹ Federal law also generally prohibits people from possessing firearms if they have been involuntarily hospitalized or committed to a mental health or substance abuse treatment facility by a court, board, commission, or other lawful authority.²

No federal law, however, requires states to report the identities of these individuals when they become ineligible to possess firearms to the National Instant Criminal Background Check System (“NICS”) database, which the FBI uses to perform background checks prior to firearm transfers. As a result, state record reporting laws are critical to ensuring the accuracy and effectiveness of the background check system.

In Michigan, upon entry of a court order directing that an individual be involuntarily hospitalized or involuntarily undergo a program of alternative treatment or a program of combined hospitalization and alternative treatment, the court must immediately order the Michigan Department of State Police (DSP) to enter the court order into the Law Enforcement Information Network (LEIN).³ Findings of legal incapacity or not guilty by reason of insanity are treated in the same manner.⁴

   (1) Is a danger to himself or to others; or
   (2) Lacks the mental capacity to contract or manage his own affairs.Federal regulation also expressly clarifies that this firearm prohibition applies to:
   (1) A finding of insanity by a court in a criminal case; and
   (2) Those persons found incompetent to stand trial or found not guilty by reason of lack of mental responsibility pursuant to [specified articles] of the Uniform Code of Military Justice. 27 CFR § 478.11.[↩]

The term includes a commitment to a mental institution involuntarily. The term includes commitment for mental defectiveness or mental illness. It also includes commitments for other reasons, such as for drug use. The term does not include a person in a mental institution for observation or a voluntary admission to a mental institution.” 27 C.F.R. § 478.11.[↩]
