District Judge Doug Herndon ruled Tuesday that the Nevada Clean Indoor Air Act is indeed constitutional and can be enforced. Herndon reiterated his previous finding that the criminal provisions were unconstitutional but that the civil penalties under the law are constitutional. While the case was pending many southern Nevada businesses flaunted the voter's call for clean air. As of today the Southern Nevada Health District has a complaint form online to report businesses that are not complying with the law.Nationwide smoking bans have been a boon to tavern owners as customers who formerly chose to stay away return for drinks and food while existing customers who are smokers go outside and smoke.
