San Francisco Court Temporarily Halts Proposed Changes to Cardroom Gaming Rules

San Francisco Superior Court Judge Richard Darwin issued a preliminary injunction that blocks Attorney General Rob Bonta’s Bureau of Gambling Control from enforcing new regulations targeting blackjack-style games and player-dealer positions at private cardrooms across California, and the order remains in effect for 45 days while parties prepare for additional hearings.

The regulations would have prohibited certain game formats that cardrooms currently offer and would have limited how player-dealer positions rotate during play, yet the court found that cardrooms raised sufficient questions about the rules’ validity to warrant a temporary pause before enforcement begins.

Background of the Regulatory Dispute

California’s tribal casinos have long maintained that blackjack-style games and certain player-banked formats fall under exclusive rights granted through tribal-state compacts, and state officials developed the new rules to align cardroom offerings with those compact terms after years of discussion between regulators and industry groups.

Cardroom operators challenged the regulations in court, arguing that the proposed changes exceeded the Bureau of Gambling Control’s authority and would force immediate operational shifts without adequate time for compliance or legislative review, and the preliminary injunction reflects the court’s assessment that those arguments merit further examination before the rules take effect.

Details of the Injunction and Its Scope

Judge Darwin’s order applies statewide to the specific provisions concerning blackjack-style games and player-dealer restrictions, and it prevents the Bureau from implementing or enforcing those measures during the 45-day window that began with the ruling.

Attorneys for the cardrooms presented evidence that abrupt implementation would disrupt existing business models and employee positions, while representatives for tribal interests countered that continued operation of the disputed games causes ongoing harm to compact rights, yet the court determined that a short delay allows both sides to present fuller records at the upcoming hearing.

Arguments Presented by Each Side

Cardroom representatives told the court that the Bureau lacked statutory authority to redefine game classifications through regulation alone, and they noted that similar formats have operated under existing state approvals for many years without prior challenge from tribal entities, whereas tribal casino advocates cited compact language that reserves certain banking games exclusively for tribes and argued that state regulators have a duty to close loopholes that allow cardrooms to offer competing products.

The Bureau of Gambling Control stated that the regulations were developed after public workshops and input from stakeholders, and it plans to defend the rules at the next scheduled proceeding, while cardroom groups have indicated they will seek to extend the injunction or obtain a permanent ruling that clarifies the boundaries of regulatory power in this area.

Timeline and Upcoming Proceedings

Further arguments in the case are scheduled for June 30, 2026, at which point the court will consider whether to extend, modify, or dissolve the preliminary injunction based on additional briefs and evidence submitted by all parties, and any ruling issued after that date will determine whether the Bureau can proceed with enforcement or must revise the regulations.

Observers note that the 45-day period provides a brief window for legislative or administrative adjustments if either side pursues those avenues before the June hearing, and the case remains one of several ongoing matters that address the intersection of tribal compact rights and non-tribal gaming operations in California.

Conclusion

The preliminary injunction issued by Judge Darwin maintains the status quo for cardroom operations involving the disputed blackjack-style games and player-dealer positions until the June 30, 2026 hearing, and the outcome of that proceeding will shape enforcement actions by the Bureau of Gambling Control moving forward.
