AZ Daily Sun:  “The state’s top prosecutor asked a judge Thursday to void a key provision in Arizona’s 2-year-old medical marijuana law.  In legal papers filed in Maricopa County Superior Court, Attorney General Tom Horne argued that voters are legally powerless to authorize anyone to sell marijuana as long as it remains illegal under federal law.  The real goal is to get a ruling declaring the state and federal laws in conflict. Horne said that will then allow him to direct the state Department of Health Services to halt the current process of licensing up to 126 dispensaries to sell the drugs even before the first one has opened its doors.”
