US District Judge Edmond E Chang said yesterday in his ruling that while the government has a duty to protect its citizens, it's also obligated to protect constitutional rights, including the right to keep and bear arms for self-defence.
However, Chang said he would temporarily stay the effects of his ruling, meaning the ordinances can stand while the city decides whether to appeal.
Broderick Drew, a spokesman for Chicago's law department, did not immediately return telephone calls for comment. The decision is just the latest to attack what were some of the toughest gun-control laws in the US In 2010, the US Supreme Court struck down Chicago's long-standing gun ban.
Chang's decision came in a lawsuit filed by the Illinois Association of Firearms Retailers and three Chicago residents. The judge noted Chicago's ban covers not only federally licensed firearms dealers, but also gifts among family members, all in the name of reducing gun violence.
Chicago, which last year had more homicides than any city in the US, still has an assault weapons ban. City officials have long acknowledged the ban on gun sales has been ineffective, because sales are legal in some surrounding suburbs and states.
