ATF Definitions of ‘Adjudicated as a Mental Defective’ and ‘Committed to a Mental Institution’ (Federal Firearms Prohibitions)
Current understanding
ATF has proposed amending DOJ regulations that define who is disqualified from possessing firearms under 18 U.S.C. 922(g)(4) by revising the definitions of ‘adjudicated as a mental defective’ and ‘committed to a mental institution.’ The categories determine which mental-health adjudications and involuntary commitments trigger a lifetime federal firearms prohibition and which records states report to NICS, so definitional changes directly affect people with prior mental-health adjudications, involuntary holds, or guardianship findings. Contested questions include whether narrower definitions restore Second Amendment access for individuals no longer deemed dangerous, or whether they weaken protections against firearm access by people found to pose a risk to self or others. Status: proposed rule.
