The UKB has sued the United States for a share of the proceeds under HR-3534, a bill that required the United States to compensate the Cherokee Nation and two other Oklahoma tribes for claims to the disclaimed drybed lands of the Arkansas River. The legislation set aside ten percent of each tribe's share of the settlement for other claimant tribes; it afforded other claimant tribes an opportunity to file claims within 180 days of the legislation. The UKB filed suit against the United States in the Court of Claims. The Cherokee Nation moved to intervene and to dismiss the UKB suit. It contended that the Cherokee Nation is an indispensable party and that it cannot be joined in the litigation because of its sovereign immunity. The Court of Claims granted both of the Cherokee Nation's motions.
