WASHINGTON - July 28, 2008 - The plaintiff in the Supreme Court case that struck down Washington's 32-year-old handgun ban filed a new federal lawsuit Monday, alleging the city's new gun regulations still violate an individual's right to own a gun for self-defense.

Dick Heller and two other plaintiffs argue that the city's regulations are "highly unusual and unreasonable" in the complaint filed in U.S. District Court.

The lawsuit claims the District of Columbia continues to violate the intent of the Supreme Court's June 26 decision by prohibiting the ownership of most semiautomatic weapons, requiring an "arbitrary" fee to register a firearm and establishing rules that make it all but impossible for residents to keep a gun in the home for immediate self-defense.

The D.C. Council was immediately criticized by gun rights advocates when it unanimously passed emergency gun legislation July 15. The law will remain in effect for 90 days, and the council expects to begin work in September on permanent legislation.

The regulations maintain the city's ban of machine guns, defined in the law as weapons that shoot more than 12 rounds without reloading. That definition applies to most semiautomatic firearms.

Handguns, as well as other legal firearms such as rifles and shotguns, also must be kept unloaded and disassembled, or equipped with trigger locks in the home unless there is a "reasonably perceived threat of immediate harm."

"A robber basically has to make an appointment" for a resident to be able to prepare the weapon for use, Heller's attorney, Stephen Halbrook, said Monday. Halbrook also called the city's definition of machine guns "bizarre."

"The District's ban on semiautomatic handguns amounts to a prohibition of an entire class of arms that is overwhelmingly chosen by American society for the lawful purpose of self defense in the home," the lawsuit alleges.
