The state of Michigan lost around $337 million in revenue from Indian tribes because of a pact that allowed them to halt payments when they lost the slot machine monopoly in the late 1990s.
Reports say that if the payments had continued, Michigan would have earned $337 million more through 2005.

There is also a claim that some of the Indian tribes were avoiding from the agreement to give 2% of the slots and video poker revenue to neighboring communities. Tribal lawyers said that the authorities lack the authority to audit the tribes' books and that they scrupulously regulate themselves without the need of outside oversight on their businesses.
