US ex rel Auginaush v Medure

An excerpt:

The tribal court adopted the arbitration transcript as the official record of its proceeding. This transcript included testimony from Medure. In August 2009 the tribal court ruled that the 1992 contract was null and void. In November 2010 the tribal court issued an order and judgment in favor of the band awarding all amounts paid under the contract, amounting to more than $18.5 million with interest accruing at the daily rate of $1,669.12.

We posted about this case in 2009.
