In District of Columbia v. Heller, the Supreme Court held the District of Columbias handgun ban to violate the Second Amendment, which provides that the right of the people to keep and bear arms, shall not be infringed. Prior District law required the registration of long guns (i.e., rifles and shotguns). The District responded to Heller by making registration of all firearms more restrictive than ever before.
Shortly thereafter, and continuing through the present, the Districts firearm registration laws have been subject to an ongoing challenge. The first named plaintiff was the same Dick Heller as in the Supreme Court case; he was joined by Absalom Jordan (a plaintiff in prior challenges) and others. The District Court rendered summary judgment in favor of the District, and the plaintiffs appealed.
