Garden Grove patient Felix Kha was pulled over by local police on June 10, 2005 for not making a full stop. The police searched Kha’s vehicle without consent and found his approximately 8 grams of medical marijuana. Kha proceeded to show the GGPD officers his doctor’s recommendation, which was met with the response that the then-recent [U.S. Supreme Court] Raich decision made medical marijuana illegal. Kha’s case was dismissed in August 2005, and he immediately asked for the return of his medical marijuana. The next day, Kha obtained a court order for return of property from the Orange County Superior Court. However, when Kha attempted to get his 8 grams back from GGPD, they refused. ASA intervened and wrote two letters to the City of Garden Grove on Kha’s behalf, demanding that it relinquish property that was rightfully his. ASA’s final letter to the City of Garden Grove threatened contempt proceedings.

On October 31, 2005, in an unprecedented move, the City of Garden Grove appealed the Orange County Superior Court ruling to return Kha’s marijuana, filing in the Court of Appeal for the Fourth Appellate District. Then on January 7, 2006, ASA filed an informal opposition on behalf of Kha, who is the real party in interest. Of particular note, California Attorney General (AG) Bill Lockyer filed an amicus (friend of the court) brief on November 1, 2006 in support of Kha and the return of his property. On December 19, 2006, the California Police Chiefs Association filed an amicus brief in support of the City of Garden Grove.

In a momentous ruling, on November 28, 2007, the Fourth Appellate District issued a unanimous 41-page published decision vindicating the rights of medical marijuana patients in no uncertain terms. On March 19, 2008, the California Supreme Court denied the City of Garden Grove's Petition for Review, as well as a request for depublication.
