With the assistance of the city of San Pablo and the Hotel Employees and Restaurant Employees Union, the Lyttons lobbied local Congressman George Miller to help turn Casino San Pablo into their reservation. Under the terms of the Indian Gaming Regulatory Act, only tribes who acquired land prior to 1988 would be eligible to operate casinos on their land. Because the Lyttons had regained their tribal status in 1991, and so were ineligible. Miller added a provision to the Omnibus Indian Advancement Act of 2000 that took CSP into federal trust and backdated its acquisition to 1988. When President Clinton signed the bill into law, the Lyttons gained the right to turn the CSP, formerly a low-stakes cardroom, into a full-fledged casino with much more profitable gambling devices and games such as slot machines and blackjack.
