A California appellate panel has struck down a ban on marijuana dispensaries in unincorporated Los Angeles County, ruling that it was pre-empted by a state law that permits cannabis operations for medical purposes.

The July 2 ruling was the latest in a string of appellate rulings by California’s state courts regarding whether municipal ordinances, regulations and other provisions that limit or ban medical marijuana dispensaries run afoul of the Compassionate Use Act of 1996, which allows marijuana use for medical purposes, and the Medical Marijuana Program, which permits medical marijuana dispensaries to operate in the state.
