The State Supreme Court struck down a law that sought to limit the amount of marijuana a medical patient can legally possess. The court, in a unanimous decision, ruled that state lawmakers were wrong to change provisions of a voter-approved proposition in 1996 that allowed patients with a doctor’s recommendation to possess an unspecified amount of marijuana. The Legislature mandated in 2003 that each patient could have a maximum of 8 ounces of dried marijuana. The Supreme Court said only voters could change amendments that they have added to the State Constitution through the initiative process.
