Says a California appellate court, ordering the police to give a man back his marijuana. State law did not bar his possession of marijuana, because he was authorized to use it under the Compassionate Use Act. Of course, the possession is still a crime under federal law, but let the feds come after him then. It's no business of California authorities.
ADDED: I'm not endorsing this decision. In fact, I have some doubts about it. I'm just presenting it for discussion at this point.
