CHICAGO (AP) — A federal court ruling tossing out Illinois' ban on concealed weapons might end the last such gun prohibition in the country, but not without a fight.

The question is whether the battle will be an appeal to the U.S. Supreme Court, which has been silent on the issue of concealed weapons, or a legislative confrontation over the court's order that Illinois adopt a law allowing concealed carry with "reasonable limitations" as in other states.

Gun control advocates urged Illinois Attorney General Lisa Madigan to quickly appeal Tuesday's ruling by the 7th U.S. Circuit Court of Appeals that Illinois' ban is unconstitutional. Madigan's office said she is studying the issue. But the ban's defenders said they were more certain of fireworks over a second part of the ruling — an order for the Illinois Legislature to come up with a law legalizing the concealed carry of weapons within 180 days.
