There are many questions surrounding Initiative 300, the social-use measure that Denver voters passed on November 8 (although the final count took a week). The city has been getting calls from people asking everything from how businesses can apply to how a new state rule will affect I-300. As we reported last week, shortly after the initiative passed, the Colorado Department of Revenue announced that it was adopting additional language in the "Conduct of Establishment" section of the Colorado Liquor Rules, declaring that a venue that already holds a liquor license cannot apply for a license to serve marijuana.And some callers are asking the city how they can quash the initiative altogether."When voters are doing citizen initiatives, [Denver officials are] always looking down the line to, if it passes, what are some of the challenges that might be brought forth to an ordinance," says lawyer John Jennings.
