On Monday, Dick Heller and two other plaintiffs filed suits against the District of Columbia's revised gun laws. The complaint challenges the following provisions of D.C. law:

The ban on all self-loading handguns (about 3/4 of handguns sold in the U.S.) by defining them as "machine guns."

Allowing registration only upon the payment of an unspecified fee for ballistic testing of the handgun.

The self-defense provision in the D.C. law which allows a gun in the home to be loaded, unlocked, and rendered functional only "while it is being used to protect against a reasonably perceived threat of immediate harm to a person within the registrant's home." The exception is too narrow, and burdens the right of self-defense.

The complaint further alleges that the aforesaid provisions are not only violations of the Second Amendment, they exceed the non-infinite home rule powers which Congress delegated to the District's city council.

There are some other problems with the new D.C. law. Handgun possession is allowed only for a person who wants the handgun for home defense; it is illegal in D.C. to acquire a handgun for recreational target shooting, to practice marksmanship before enrolling in the military or joining a police department, or for lawful hunting Maryland or Virginia. The only time that a gun can be unlocked is when it being used for self-defense against an immediate attack; accordingly, it is illegal to remove the lock from an unloaded gun in order to clean the gun. The problem would be resolved by the requested relief of enjoining all enforcement of the gun lock law against defensive firearms.

Attorneys in the case are Stephen Halbrook and Richard Gardiner, of Fairfax, Virginia. They both been involved in firearms law and policy for three decades, and they are excellent lawyers. Halbrook has a 4-0 record as lead counsel in Supreme Court cases.
