This is for e City of Garden Grove that you were talking about.
On December 1, 2008, the Supreme Court decided not to hear arguments in City of Garden Grove v. Superior Court of Orange County, leaving a lower court ruling standing which requires local police officers to enforce state law, not federal law. The case stems from a traffic stop of Felix Kha, who had 8.1 grams of medical marijuana in a container, which the police officers confiscated. The ruling requires police officers to return the seized medicine.[14]
"But it must be remembered it is not the job of the local police to enforce the federal drug laws as such."[15]
