A fresh legal challenge has emerged against the North Fork Mono Casino & Resort in California, placing renewed attention on a project that has spent more than two decades navigating regulatory reviews, court battles, and political disputes.
The Picayune Rancheria of the Chukchansi Indians, owner of Chukchansi Gold Resort & Casino in Madera County, has filed another federal lawsuit seeking to prevent the North Fork Rancheria of Mono Indians of California from launching gaming operations at its new resort, which is scheduled to open in October. The filing marks the third federal case brought by Picayune against the project during the past 14 years.
The dispute centers on the legality of the North Fork casino’s approvals and whether the project satisfies both federal and state requirements for tribal gaming on land acquired after 1988.
“This lawsuit seeks to prevent that unlawful gaming before it starts,” Picayune’s complaint states, according to The Fresno Bee.
Long-Running Dispute Returns to Federal Court
The latest case was submitted to the U.S. District Court for the Eastern District of California in June. Alongside the North Fork Rancheria, the complaint names the National Indian Gaming Commission and Station Casinos, the Las Vegas-based company selected to operate the resort.
Picayune argues that North Fork lacks a valid state concurrence required under the Indian Gaming Regulatory Act (IGRA) for gaming on certain trust lands. According to the lawsuit, both federal and state approval are necessary under the law’s “two-part determination” process.
The Chukchansi tribe contends that recent California court decisions effectively eliminated the state authorization previously granted to the project. The legal argument stems from developments tied to Proposition 48, a 2014 ballot measure involving North Fork’s tribal-state gaming compact.
Former California Governor Jerry Brown had supported the project and approved a tribal-state compact after the federal government determined in 2011 that the North Fork tribe maintained ancestral ties to the Highway 99 site. The federal government subsequently placed the land into trust.
However, California voters later rejected the compact through Proposition 48. In subsequent litigation, state courts concluded that the election outcome invalidated Brown’s concurrence. The California Fifth District Court of Appeal upheld that conclusion in December 2025, and the California Supreme Court declined to review the matter in April 2026.
Picayune now argues that those rulings mean North Fork no longer possesses the state approval required under IGRA.
North Fork Maintains Federal Approval Supports Operations
North Fork Rancheria continues to move toward its planned opening and has rejected the legal arguments raised by its neighboring tribe.
In court filings responding to the new lawsuit, North Fork noted that it successfully defended its position in two previous federal cases brought by Picayune.
“Undeterred by that history, Picayune has repackaged those claims for this Court,” the tribe said in court documents.
North Fork has consistently maintained that gaming rights on the trust land near Highway 99 are controlled by federal law. The tribe previously stated that its authority to conduct gaming on the property is “governed exclusively by federal law.”
The tribe also points to earlier federal litigation. Following the rejection of the tribal-state compact, North Fork pursued its own legal action alleging that California failed to negotiate a replacement agreement in good faith. A federal judge ruled in favor of North Fork, leading to mediation efforts. When no new compact emerged, the U.S. Department of the Interior established regulations in 2016 governing casino operations.
According to North Fork’s recent court filings, a federal judge previously rejected a similar challenge from Picayune concerning state concurrence.
Station Casinos has also moved to dismiss the latest complaint. In court documents, the operator described the lawsuit as an “eleventh-hour lawsuit recycling previously rejected arguments in a last-ditch effort.”
October Opening Plans Continue Despite Legal Uncertainty
Construction of the resort began in 2024 after years of delays linked to both state and federal litigation. Planning for the development dates back to 2003.
The project carries a reported investment of $725 million and spans approximately 264,000 square feet. Local officials have long anticipated its arrival, citing the potential creation of more than 1,500 jobs in Madera County.
Once operational, the resort is expected to offer more than 2,400 slot machines and 40 table games. Visitors will also have access to eight dining venues, including full-service restaurants such as Manzanita Steakhouse and Clubhouse 99, along with a food hall containing six outlets. Plans also call for four bars and, in a later phase, a 200-room hotel.
The location of the casino remains a key point of contention. Picayune operates Chukchansi Gold Resort & Casino near Coarsegold along Highway 41, while the North Fork property sits near Highway 99, a heavily traveled transportation corridor serving Madera and the wider Fresno region. Opponents have argued that the Highway 99 location provides a significant competitive advantage and lies more than 30 miles from North Fork’s rancheria in the mountains of Madera County.
