North Fork Mono Casino Opens on Highway 99 in Madera County While Chukchansi Federal Lawsuit Awaits Ruling

The North Fork Rancheria of Mono Indians opened its North Fork Mono Casino & Resort on Highway 99 near Madera, California, on 27 October 2026, while a federal judge in Fresno has yet to rule on a rival tribe's request to stop gaming at the site. The casino opened a day ahead of its advertised 28 October date, more than two decades after the tribe began planning it.

The neighboring Picayune Rancheria of the Chukchansi Indians, which runs Chukchansi Gold Resort & Casino in Coarsegold, filed the federal suit in late summer. It is the tribe's third federal attempt in about 14 years to block the project, according to Action Network.

What opened

The property is one of the largest new tribal casinos in California this decade. Station Casinos, the Las Vegas locals operator owned by Red Rock Resorts, manages it for the tribe.

Tribal leader Elaine Bethel Fink told ABC30 the project means new revenue for a tribe that has "existed on programs and grants." Hundreds of people attended the ribbon-cutting.

The lawsuit

Chukchansi wants the court to bar gaming at the site. US District Judge Kirk E. Sherriff of the US District Court for the Eastern District of California heard arguments on its request for preliminary relief on 9 October 2026 and had not ruled when the doors opened, according to 500 Nations. North Fork has moved to dismiss the case, GamblingNews reported.

The suit also targets the National Indian Gaming Commission (NIGC), the federal regulator of tribal gaming, over its approval of North Fork's management agreement with Station Casinos, Action Network said. Chukchansi's core argument is that North Fork lacks a valid concurrence from California's governor. North Fork says its federal approvals were granted before any state ruling, remain valid, and cannot be undone by state courts.

Both sides' claims are allegations before the court. No federal judge has ordered the casino to close.

Why the concurrence matters

The fight turns on a rule in the Indian Gaming Regulatory Act of 1988 (IGRA), the federal law that governs tribal casinos. Gaming on land taken into federal trust after October 1988 generally needs a two-part determination by the US Department of the Interior and the agreement, or concurrence, of the state's governor.

North Fork's position is that the federal decisions made before the referendum still govern its trust land. Chukchansi says the state rulings remove the legal foundation for gaming under IGRA.

Competition in the Central Valley

Behind the legal arguments is a commercial one. Chukchansi Gold is in the Sierra foothills, while North Fork's site sits on Highway 99, the Central Valley's main north-south road, between Fresno and Merced. FOX26 reported that Chukchansi argues the location gives North Fork an unfair advantage.

Off-reservation casino projects remain contentious in California. Governor Gavin Newsom in 2024 urged the Interior Department to halt two other tribal casino projects in Sonoma and Solano counties, and tribes have shown they will go to court to protect their markets, as in their suit against California cardrooms and the California tribes' case against Kalshi and Robinhood.

What happens next

The next step is Judge Sherriff's decision on Chukchansi's request and on North Fork's motion to dismiss. Either side could appeal to the US Court of Appeals for the Ninth Circuit. Until then, the casino stays open.
