The District of Columbia Council plans to vote on new gun legislation Tuesday as officials scramble to comply with last month's U.S. Supreme Court ruling that struck down the city's 32-year-old ban.

The emergency legislation announced Monday would allow handguns if they are used only for self-defense in the home and carry fewer than 12 rounds of ammunition.

The proposal, which maintains some of the city's strict gun ownership rules and adds more regulations, was immediately criticized by gun rights advocates threatening more legal action.

The emergency legislation, which has strong support from the council, would remain in effect for 90 days. It adopts many of the regulations proposed earlier this month by D.C. Council member Phil Mendelson.
