Grace v. District of Columbia, Civil Action No. 2015-2234

The District of Columbia required applicants for concealed-carry licenses to show a "good reason" (a special need for self-defense) in order to obtain a permit under D.C. Code § 22-4506 and related regulations.
Plaintiffs challenged the "good reason" requirement as an unconstitutional burden on the Second Amendment right to carry firearms for self-defense outside the home.
The district court (Grace) preliminarily enjoined enforcement of the good-reason requirement, finding it likely unconstitutional.
The D.C. Circuit consolidated Grace with Wrenn and held that the good-reason law operated as a de facto total ban on carrying firearms for self-defense beyond the home.
The D.C. Circuit concluded the existing record was adequate, declined further factual development, and remanded with instructions to enter permanent injunctions against enforcement of the good-reason law.
Following denial of rehearing en banc and issuance of the mandate, the district court entered a permanent injunction consistent with the D.C. Circuit's instructions.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether D.C.'s "good reason" requirement violates the Second Amendment right to carry firearms for self-defense outside the home	The requirement unconstitutionally burdens the individual right to carry for self-defense beyond the home	The law is a permissible regulatory restriction, not a total ban; it advances public safety	The D.C. Circuit: the good-reason law functions as a total ban on the constitutional right to carry beyond the home and is therefore unconstitutional; permanent injunction ordered
Whether further factual development was necessary before a final remedy	Plaintiffs: existing record sufficient to resolve constitutionality and enter permanent relief	Defendant: additional factual development/remand needed to justify remedy	The D.C. Circuit: additional development would be a waste of judicial resources; record was sufficient and remand should direct entry of permanent injunctions
