Foes of the casino proposed on Rohnert Park's northwest boundary have been energized by a U.S. Supreme Court decision that creates new legal avenues for them to attempt to derail the project.
The decision in Match-E-Be-Nash-She-Wish Band of Pottawatomi Indians v. Patchak affirmed a Michigan man's right to sue the federal government over its decision to take land into trust for a tribe that planned a casino there.
The Monday ruling also changed from 30 days to 6 years the length of time available to people to sue the government about such decisions. The Secretary of the Interior took the Graton Rancheria property into trust in 2010.
"That's a huge, huge victory as far as we're concerned," said Mike Healy, a Petaluma councilman who has authored a lawsuit challenging the casino project for the Stop the Casino 101 group.
A similar Stop the Casino 101 lawsuit was dismissed in 2010 by a court that ruled it premature.
The group in May sued the state over the agreement it signed with the Federated Indians of Graton Rancheria allowing the project to go forward. It contends that because the Graton Rancheria casino site was not historically sovereign Indian territory, the state still controls it, making the planned Las Vegas-style casino illegal.
Another lawsuit now is planned against the federal government, Healy said.
"It will be soon," he said.
The lawsuit against the state is pending, but Sonoma County Superior Court Judge Elliot Daum denied Stop the Casino 101's request for a temporary restraining order to prevent work on the project from starting.
Experts in Indian law agree that the Supreme Court decision gives opponents additional options as they continue years of legal attempts to stop the casino from rising on 254 acres just south of Home Depot.
