Indianapolis' stricter smoking ban has been upheld in federal court.

Listen:

A group of 10 bar owners filed an injunction to stop the ban, claiming the ban hurt business. The group claimed their business had dropped as much as 60-percent after the ban took effect.

Attorney Mark Small represented some of the bar owners and he claimed the original ordinance written in 2005, which the new ordinance was modeled after, was based on bad sciene. The group claimed studies used to write the ban concerning the density of secondhand smoke was not correct. But Judge Richard Young ruled the ban is not unconstitutional and also found no evidence the ban would cause bars or restaurants to close.

The new ordinance, which prohibits smoking in bars, restaurants, bowling alleys and hotel rooms, went into effect last year.
