Currently the federal government has a wide range of powers over reservation land such as the ability to prosecute crime. For better or for worse, Congress can expand these powers at any time to include dissolving the reservation. The law in all these aforementioned areas is well settled.

The issue in this case was with a state government, specifically Oklahoma. This ruling will limit Oklahoma's ability to prosecute crime when (1) it occurs on the reservation and (2) involves members of the tribe. Congress would have to act to change this, or some agreement could be reached with the tribe.
