Koi Nation’s Sonoma Casino Development Faces Legal Delays
Significant Challenges Halt Koi Nation’s Casino Project
The Koi Nation’s plan to establish a major casino resort in Sonoma County has encountered a major legal setback. A federal judge invalidated the US Department of the Interior’s approval for placing the land in trust for the project, causing delays. Neighboring tribes and the State of California have contested the Koi Nation’s expansion plans, further complicating the situation.
The Controversial $600 Million Shiloh Casino and Resort
At the heart of the dispute is the ambitious $600 million Shiloh Casino and Resort, designed to be built near Windsor in California’s renowned wine country. The proposal included a 400-room hotel, a 530,000-square-foot gaming area, and was expected to create approximately 1,100 permanent jobs, promising economic benefits to the area.
Judge Rita F. Lin of the Northern District of California has put an indefinite pause on the development after the Federated Indians of Graton Rancheria (FIGR), operators of the nearby Graton Casino Resort, challenged the project. FIGR argued that the Koi Nation lacks sufficient ancestral ties to the proposed site and that the federal approval process was flawed.
The State of California and Governor Gavin Newsom also joined the legal battle in May, arguing that the Department of the Interior failed to follow mandated procedures before approving the casino. These procedures require thorough consultations with local officials and assurances that the project would not negatively impact the community.
Federal Review Likely to Extend Timelines
Judge Lin’s ruling represents a partial victory for the opposing parties. She determined that the Bureau of Indian Affairs director did not have the authority to approve the trust placement—only the Secretary of the Interior holds this power. Additionally, the evidence presented did not adequately demonstrate the Koi Nation’s historical connection to the Shiloh land.
The record does not support the Department of the Interior’s conclusion that the Koi established significant historical ties to the Shiloh parcel.

The court further found that federal agencies failed to properly consult with FIGR about cultural and historical concerns, violating preservation laws. However, other aspects such as environmental factors received sufficient consideration. Due to these shortcomings, the DOI’s approval was overturned.
The ruling requires the Department of the Interior to revisit its decision, undertake renewed stakeholder consultations, and closely assess whether exceptions in gaming laws apply to the Shiloh land. This process is expected to be lengthy, potentially taking several years, signaling that the Koi Nation’s casino plans face continued uncertainty.
