The state's high court will attempt to clarify marijuana's hazy legal status in California.
The California Supreme Court on Wednesday voted unanimously to review how cities and counties regulate marijuana dispensaries.
The court will address whether local governments can bar the pot shops despite voter passage of Proposition 215, which legalized marijuana use with a doctor's recommendation.
The court also will consider the continued conflict between state and federal authorities, who don't recognize Proposition 215. Under federal law, marijuana is illegal in all forms.
An appellate court last year struck down Long Beach's attempt to license pot stores, ruling that the local ordinance conflicted with federal law. Another appellate court upheld Riverside's right to close and prohibit dispensaries.
The Supreme Court has not yet scheduled oral arguments for the cases.
