Indianapolis’ City-County Council failed Monday to override Mayor Greg Ballard’s veto of a proposal to strengthen the city’s smoking ban. Members voted 16-12 to reverse his decision, falling short of the 20 votes needed. Ballard nixed the measure Friday, saying he did not agree with a requirement that private clubs choose between allowing smoking and admitting minors. The proposal also would have banned smoking in bars, bowling alleys and hotel rooms. Proponents say they won’t give up on a broader ban. State legislators, meanwhile, also are considering a similar statewide measure.
