- California court halts implementation of extensive blackjack-style gaming regulations
- Cardrooms claim new regulations could lead to significant job losses and reduced local tax income
- Legal dispute revolves around tribal gaming exclusivity and regulatory authority in California
California cardrooms achieved a critical legal victory on Thursday as a judge in San Francisco temporarily blocked the enforcement of new state regulations targeting blackjack-style games.
Judge Richard Darwin of the San Francisco Superior Court issued a preliminary injunction that stops California officials from implementing the new regulations, which cardrooms describe as an outright “ban on blackjack.” These regulations, formulated by the Bureau of Gambling Control and authorized earlier this year by the Office of Administrative Law, were scheduled to go into effect on June 1.
Cardroom owners have expressed serious concerns that the new rules could decimate their operations, eliminate jobs, and drastically reduce local tax revenue that numerous California cities depend on.
This ruling enables cardrooms to proceed with their blackjack-style games while two related legal challenges are in progress.
‘California Games’
Central to the conflict is an ongoing struggle between California’s tribal casinos and commercial cardrooms over “banked” games, where participants play against the house instead of against one another.
According to California law, tribal casinos have the exclusive right to operate certain banked games, yet cardrooms have navigated a workaround for years using third-party proposition player services (TPPPs).
These third-party entities serve as the bank during blackjack-style games, allowing cardrooms to maintain that they are not directly offering prohibited casino games.
Tribal gaming representatives have long contended that this arrangement infringes upon their exclusive rights to casino-style games.
The proposed regulations would require that the “player-dealer” role rotate among players every 40 minutes. Moreover, TPPP companies would no longer be permitted to act as the bank continuously, and cardrooms would be barred from using the terms “blackjack” or “21” for their games.
Operators have argued that these changes could render many games unviable from a commercial perspective.
Who Holds the Authority?
The ruling on Thursday did not establish the legality of cardroom blackjack itself but assessed whether the Bureau of Gambling Control (BGC) had the jurisdiction to implement such extensive changes.
Represented by the California Gaming Association, cardrooms asserted that legislative authority over gaming regulations resides with the California Gambling Control Commission, not the BGC.
Judge Darwin suggested he believed the bureau likely exceeded its powers. The Gambling Control Act does not explicitly delegate authority to the bureau to restrict or significantly alter approved card games, he indicated.
The injunction will remain effective for up to 45 days while the court deliberates additional written arguments, with another hearing slated for June 30.
This verdict represents a significant, albeit temporary, triumph for California cardrooms in one of the state’s most pivotal gambling legal battles in recent years.
