East Valley Tribune:  “Federal attorneys asked a judge on Monday to throw out a lawsuit filed by Gov. Jan Brewer seeking a ruling about the legality of the state’s medical marijuana law.  Deputy U.S. Attorney Scott Risner said there is no legal basis for the lawsuit. Risner told U.S. District Court Judge Susan Bolton in legal papers filed in her court that, absent some actual threat of prosecution under federal drug laws by his office, the question is purely academic and therefore not a proper subject for litigation.”
