The California Gaming Association’s lawsuit against the new state gaming rules is a pair of San Francisco Superior Court cases filed in March 2026 that seek to overturn regulations banning blackjack-style games and tightening how player-dealer games run at the state’s commercial cardrooms. On May 21, 2026, Judge Richard Darwin issued a preliminary injunction blocking enforcement, finding the Bureau of Gambling Control likely exceeded its authority. The regulations remain frozen while the litigation continues.1Research file
What the Challenged Rules Do
The California Office of Administrative Law approved the two rule packages on February 6, 2026, and they took effect April 1, 2026. They were developed by the Department of Justice’s Bureau of Gambling Control under Attorney General Rob Bonta.
The blackjack regulations prohibit any game in which a player or dealer can “bust” by exceeding 21, eliminate automatic wins on “natural” hands, and ban the words “blackjack” and “21” in game titles. Wins and losses must be decided by proximity to a target number other than 21.
The player-dealer regulations rewrite how third-party proposition player providers, known as TPPPs, work at the tables. A TPPP employee currently acts as the bank, covering all wins and losses while the cardroom collects a fee. Under the new rules, the player-dealer position must be offered to every seated player before each hand and must rotate to at least two non-TPPP players every 40 minutes. If the rotation requirement isn’t met, the game ends. Only one TPPP is allowed per table.
Cardrooms had to submit compliance plans by June 1, 2026, with the Bureau empowered to withdraw game approvals from noncompliant rooms beginning June 12, 2026. Full blackjack modifications were due by September 30, 2026, and player-dealer modifications by October 31, 2026.
What the Lawsuits Argue
On March 9, 2026, the California Gaming Association, joined by the California Cardroom Alliance and the nonprofit Communities for California Cardrooms, filed two suits in San Francisco County Superior Court. Both are captioned California Gaming Association et al. vs. Rob Bonta et al. Case No. CPF26519606 challenges the player-dealer regulations, and Case No. CPF26519609 challenges the blackjack rules.
The industry’s core arguments:
- The Bureau of Gambling Control lacks statutory authority under the Gambling Control Act to restrict or prohibit games it had previously approved. The CGA called the regulations “an unprecedented power grab by the Attorney General.”
- The rules “reverse decades of settled law and practice” under which multiple attorneys general approved the targeted games as lawful. The CGA pointed to four prior appellate decisions affirming that cardrooms may operate non-banked versions of blackjack and baccarat.
- The Attorney General failed to identify any specific public safety concern justifying the changes.
- Of 1,764 public comments submitted during rulemaking, nearly all opposed the regulations, and the state adopted the rules “without adequately addressing” them.
- The Attorney General’s own Standardized Regulatory Impact Assessment estimated the rules would “eliminate at least 50 percent of cardroom jobs and revenue.”
CGA President Kyle Kirkland said the industry had “repeatedly raised legal and economic concerns throughout the rulemaking process, but the attorney general refused to engage with the communities and working families who will be harmed.”
The Preliminary Injunction
Judge Richard Darwin granted the preliminary injunction on May 21, 2026, barring state officials from enforcing either rule package. He found the Bureau of Gambling Control likely “exceeded its authority” under the Gambling Control Act by attempting to ban the cardrooms’ most popular table games. The injunction runs for a maximum of 45 days. Darwin ordered additional written briefing and set the next hearing for June 30, 2026.
Kirkland said the ruling confirmed that the Bureau “exceeded their authority by attempting to rewrite California gaming law.” The California Department of Justice said it would “respond appropriately in court.”
What’s at Stake Financially
According to the Department of Justice’s regulatory impact assessment, California’s 86 licensed cardrooms generated about $1.356 billion in revenue in 2023, employed roughly 18,000 people directly, and contributed about $3 billion to the state economy. A 2019 industry-commissioned study put the broader footprint at $5.6 billion annually and estimated more than 32,000 supported jobs.
The DOJ assessment estimated the player-dealer rotation rules alone would cost cardrooms $396 million in the first year by eliminating half of all TPPP revenue, with tribal casinos absorbing about $198 million of the diverted business. The blackjack ban was projected to cost an additional $68 million, with tribal casinos gaining about $34 million.
Several California cities rely heavily on cardroom tax revenue. San Jose estimated it could lose $32 million a year, money that funds 95 police officers, 106 firefighters, 911 dispatch, and homelessness programs. The City of Commerce, where Commerce Casino generates more than $30 million annually and accounts for over 40 percent of the city’s $80 million general fund, put a quarter-cent sales tax measure on its June 2026 ballot to offset projected losses of up to $18 million a year. Bell Gardens, Compton, Gardena, and Hawaiian Gardens have weighed similar emergency measures.
The Tribal Dispute Behind the Rules
The regulations grew out of a conflict stretching back more than two decades. Propositions 5 (1998) and 1A (2000) amended the state constitution to authorize tribal casinos to offer slot machines, lottery games, and banked card games such as blackjack under tribal-state compacts. Tribes have long argued this gives them exclusive rights to house-banked games and that cardrooms illegally encroach on that exclusivity by using TPPPs to simulate a house bank.
Cardrooms counter that their games are player-banked, not house-banked, and that the Bureau has approved these formats for decades under multiple attorneys general. Bonta’s office frames the rules as enforcement of the constitutional line. Spokesperson Jonathan Underland told CalMatters that “the constitution is a hard line, and Rob Bonta is committed to enforcing it.”
A parallel tribal case is moving through the courts under Senate Bill 549, the Tribal Nations Access to Justice Act, which Governor Gavin Newsom signed in September 2024. SB 549 gave gaming tribes a one-time right to sue cardrooms over the legality of their games, with relief limited to a judicial declaration. Seven tribes sued on January 2, 2025, in Agua Caliente Band of Cahuilla Indians v. Parkwest Bicycle Casino, LLC in Sacramento County Superior Court, and two more joined in April 2025. On October 10, 2025, Judge Lauri Damrell dismissed the case, ruling that the federal Indian Gaming Regulatory Act preempts the state law authorizing the suit. The tribes appealed to the Third District Court of Appeal, where briefing was underway in early 2026.
A 2019 federal lawsuit by three tribes seeking to shut down cardroom blackjack and baccarat was also dismissed, with the court ruling that the tribes’ compacts “did not include any express terms” obligating the state to preserve the exclusivity the tribes claimed.
What’s Next
With the preliminary injunction in place, the cardroom regulations are blocked while the case proceeds. Judge Darwin’s next hearing was set for June 30, 2026, when the Attorney General’s office was expected to argue for lifting the injunction. The tribes’ appeal of the dismissed SB 549 case continues separately in the Third District Court of Appeal. Together, the two tracks could reset the legal boundary between tribal and cardroom gaming in California.
