California Governor Gavin Newsom and the State of California sued the federal government Friday over its decision to greenlight a massive tribal casino project in Sonoma County wine country, claiming federal officials flouted the law and undermined state sovereignty.

In the suit filed in the Northern District of California, the state challenges the federal Department of Interior’s approval for the Koi Nation of Northern California to build a sprawling gambling complex on the “Shiloh Site,” 68.6 acres of land adjacent to the town of Windsor.

The planned development would include 2,750 slot machines, 105 table games, a 400-room hotel and facilities capable of hosting more than 10,000 people.
