On Friday, the Michigan Supreme Court cleared the way for Detroit voters to determine whether or not marijuana should be legal. The Court denied an appeal from a February decision ruling that the Detroit Election Commission could not prevent a legalization proposal from appearing on the ballot. If the proposal is approved in August, it would be legal under Detroit city code for people over 21 to possess and use less than an ounce of marijuana on private property. The proposal does not change any federal or state laws prohibiting the use and possession of marijuana. The Detroit Election Commission has been trying to block the referendum from the ballot since 2010.
