The lawsuit filed in U.S. District Court asks that a judge halt the review process for the casino and issue a temporary restraining order and then an injunction to prevent an illegal rejection of the proposal.
The Keshena-based tribe asked last month that the Interior Department temporarily suspend the review of the proposal and postpone it until the next administration takes office, but the request was denied.
Named as defendants are the Department of the Interior and its secretary, Dirk Kempthorne.
