The Arizona Supreme Court ruled today to keep Proposition 205 on Arizona ballots in November.

Voters will decide Nov. 8 whether to legalize recreational marijuana for adults 21 and older. Currently, medical marijuana is legal in Arizona.

The Arizona Chamber of Commerce and Industry and a group of anti-marijuana advocates filed a suit in July alleging that recreational marijuana proponents improperly communicated their message in their petitions. The court denied the plaintiffs' motion for a preliminary injunction.

Joseph Kanefield, a partner and election attorney for Ballard Spahr, said he wasn't surprised by the court's decision. "It's consistent with its prior precedent to not pre-judge the merits of a proposed ballot measure before the election," he said.
