Not long after he took office in 2003, former Gov. Arnold Schwarzenegger offered Indian tribes a deal his administration believed was a win for both sides: They could add hundreds of slot machines to their casinos if they paid a double-digit percentage of their earnings to the state's general fund. Although some tribes leaped at the offer, generating about $350 million a year for the state, the Rincon Band of Luiseño Indians argued that it amounted to an unlawful tax.
The U.S. 9th Circuit Court of Appeals agreed last year, and on Monday the Supreme Court declined to hear the state's challenge to that ruling. The court's move could exacerbate California's budget problems, but it's a narrow and appropriate reading of the law.
The states' power to regulate gambling on sovereign Indian reservations derives from the Indian Gaming Regulatory Act, a 1988 federal law that required most tribes to seek permission from state government before offering casino-style gambling. The law orders states to bargain in good faith, and it explicitly forbids them from imposing taxes or fees beyond what's needed to defray the cost of regulating the casinos.
California negotiated compacts with numerous tribes in 1999 to allow limited casino-style gambling in exchange for a portion of the revenue, to be paid into two special funds directly related to tribal economic development and the costs imposed by the casinos. State voters validated the compacts in 2000 when they passed Proposition 1A, which legalized casino gambling only on tribal lands.
