District of Columbia Firearm Freedom Act

(a) In general. No law, regulation, rule, or policy of the District may require any person to obtain, before acquiring, receiving, possessing, or bringing into the District a firearm otherwise lawful under Federal law, any license, certificate, registration, approval, permit, or other authorization as a condition precedent to such acquisition, receipt, possession, or importation.

(b) No criminal liability for mere lack of prior approval. No person may be arrested, prosecuted, or subjected to criminal penalties under District law solely because the person acquired, received, possessed, or brought into the District a firearm without first obtaining District authorization described in subsection (a), if the person is not a prohibited person under Federal law.
