Lawyers, medical cannabis advocates, patients, city officials and reporters packed into a San Francisco courtroom Thursday for the first hearing in the federal government’s effort to shutter the state’s largest marijuana dispensary.

Landlords for Harborside Health Center in Oakland and San Jose, who face forfeiture of their properties, asked U.S. Magistrate Judge Maria-Elena James to stop the sale of marijuana at their properties, while Oakland’s attorneys implored James to first hear the city’s suit challenging the legality of the federal forfeiture actions.
