- California judge blocks enforcement of sweeping blackjack-style gaming regulations
- Cardrooms argue new rules would devastate jobs and local tax revenue
- Legal fight centers on tribal exclusivity and gambling authority in California
California cardrooms scored a major legal victory Thursday after a San Francisco judge temporarily blocked new state gambling regulations that target blackjack-style games.
San Francisco Superior Court Judge Richard Darwin issued a preliminary injunction preventing California officials from enforcing the new rules, which cardrooms say amount to a “blackjack ban.” The regulations, adopted by the state Bureau of Gambling Control and approved earlier this year by the Office of Administrative Law, had been set to take effect on June 1.
Cardroom operators have warned the changes would devastate their businesses, eliminate jobs and slash local tax revenues relied upon by dozens of California cities.
The ruling allows cardrooms to continue operating blackjack-style games while two related lawsuits proceed through the courts.
‘California Games’
At the heart of the dispute is a long-running battle between California’s tribal casinos and commercial cardrooms over so-called “banked” games, casino-style games in which players compete against the house rather than one another.
Under California law, tribal casinos have exclusive rights to operate certain banked games. Cardrooms, however, have spent decades using a legal workaround that relies on third-party proposition player services, or TPPPs.
These outside companies act as the bank during blackjack-style games, allowing cardrooms to argue they are not directly operating prohibited casino games.
Tribal gaming interests have long argued the arrangement violates their exclusivity over house-banked games.
Under the new rules, the role of “player-dealer” would have to rotate among players at the table every 40 minutes. TPPP companies would no longer be allowed to continuously serve as the bank. Cardrooms also would be prohibited from calling games “blackjack” or “21.”
Operators argued the changes would make many games commercially unworkable.
Who Has the Power?
Thursday’s ruling did not determine the legality of cardroom blackjack. It focused on whether the Bureau of Gambling Control (BGC) had the authority to impose such sweeping changes.
The cardrooms, represented by the California Gaming Association, argued the Legislature granted statewide rulemaking authority over gambling games to the California Gambling Control Commission — not the BGC.
Darwin indicated he believed the bureau likely exceeded its authority. The Gambling Control Act did not clearly grant the bureau the power to prohibit or substantially redefine approved card games, he said.
The injunction will remain in place for up to 45 days while the court considers additional written arguments. Another hearing is scheduled for June 30.
The decision marks a significant, though temporary, win for California cardrooms in one of the state’s most consequential gambling disputes in years.
