From ABC News:

A federal judge has potentially opened a new market to gun dealers after ruling that Chicago ordinances banning the sale of guns within the city’s limits in an effort to reduce gun violence are unconstitutional.

U.S. District Judge Edmond E. Chang said Monday 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-defense. However, Chang said he would temporarily stay the effects of his ruling, meaning the ordinances can stand while the city decides whether to appeal.

It’s like he’s begging the City to challenge his ruling.
