Court Issues Preliminary Injunction Against Gambling Regulations
A judge of the San Francisco Superior Court has temporarily blocked California gaming regulations that would have effectively banned blackjack-style games at state-licensed cardrooms. Judge Richard Darwin issued a preliminary injunction, preventing the Bureau of Gambling Control from enforcing the new rules while legal proceedings continue.
The regulations were introduced under Attorney General Rob Bonta and targeted the way cardrooms offer certain table games. By pausing enforcement, the court allows cardrooms to continue operating blackjack, baccarat, and pai gow poker under their current structure until the underlying lawsuits are resolved.
The California Gaming Association, which represents cardrooms and filed the legal challenge, stated that the court found clear and convincing evidence that enforcement would cause irreparable harm to cardrooms and their surrounding communities.
Dispute Focuses on Third-Party Proposition Player Model
The legal dispute centers on how cardrooms structure games that resemble traditional banked casino offerings. Under California law, tribal casinos are permitted to offer banked games, where players compete directly against the house.
Cardrooms operate under a different model. Instead of acting as the house, they offer games in which players compete against each other. To maintain continuous gameplay, cardrooms rely on third-party proposition player services. These services fill empty seats and provide the bankroll necessary for each hand, allowing the game to proceed even when there are not enough independent players at the table.
The proposed regulations would have narrowed or closed the legal framework that permits this model. According to the California Gaming Association, this would have amounted to a de facto statewide ban on the affected blackjack-style games in cardrooms.
Tribal-owned casinos, through a coalition of Native American tribes, have argued that the use of third-party proposition players constitutes an unlawful workaround. They contend that the structure allows privately owned cardrooms to compete with tribal casinos in offering banked-style games and diverts significant revenue from tribal communities.
Cardrooms File Lawsuits Challenging Bureau’s Authority
Cardrooms filed two lawsuits in early 2026 seeking to invalidate the regulations. The California Gaming Association maintains that the Bureau of Gambling Control exceeded its statutory authority by effectively rewriting state gaming law through administrative rulemaking.
Kyle Kirkland, owner of Club One Casino in Fresno and president of the association, said the ruling supports the cardrooms’ position that the bureau attempted to impose a statewide ban without legislative approval. He stated that cardrooms have offered the targeted games for decades and that the regulations threaten established business models.
Kirkland also pointed to the economic role of cardrooms at the local level. He said Club One contributes approximately $1 million annually in tax revenue to the city of Fresno. More broadly, the association argues that cardrooms support thousands of jobs and generate funding for municipal services.
The association further stated that the Bureau of Gambling Control received more than 1,700 public comments opposing the regulations before finalizing them without what it described as meaningful changes.
Economic Impact Cited in Attorney General’s Analysis
The economic analysis prepared under Attorney General Bonta acknowledged that the regulations could eliminate more than 50% of cardroom revenues statewide. According to that analysis, such a decline could threaten jobs and reduce local tax revenues that fund police, fire protection, parks, youth programs, and other city services.
These figures formed part of the broader debate presented to the court. While tribal groups argue that cardrooms’ current practices undermine the exclusivity granted to tribal casinos for banked games, cardrooms maintain that the regulatory changes would cause immediate and significant economic disruption.
The court’s finding of potential irreparable harm indicates that it considered the financial and operational consequences for cardrooms and municipalities as part of its decision to grant preliminary relief.
Implications for California’s Gaming Landscape
The preliminary injunction does not resolve the underlying legal dispute but maintains the status quo for now. Cardrooms across California may continue offering blackjack-style games using third-party proposition player services while the court evaluates the merits of the lawsuits.
For operators and industry observers, the case highlights ongoing tensions between tribal casino interests and state-licensed cardrooms over game formats and competitive boundaries. The outcome of the litigation could determine how California interprets the distinction between banked and player-banked games under existing law.
The dispute also underscores the potential financial consequences of regulatory changes in established gambling markets. With more than half of cardroom revenues potentially at stake, the final court decision may influence both market structure and local government funding streams.
Our Assessment
The court’s preliminary injunction prevents immediate enforcement of regulations that could have removed a significant portion of cardroom revenue in California. The ruling allows blackjack-style games to continue under the current third-party proposition player model while legal challenges proceed. The final outcome will determine whether the Bureau of Gambling Control has the authority to restrict this model and may shape the balance between tribal casinos and state-licensed cardrooms under California gaming law.
