In case of an issue, you can turn to the CGCC, Department of Justice Bureau of Gambling Control, or the San Jose Police’s Division of Gaming Control. The authority that monitors the activities of the gambling rooms and casinos is the California Gambling Control Commission (CGCC).
You can find detailed information for each state, but the main gambling law to start with is the Gambling Control Act. Anyone who intends to visit a San Jose casino poker room should get familiar with the US gambling laws and the regulations of the State of California Department of Justice.
