Here is the petition in Klickitat County v. Confederated Tribes and Bands of the Yakama Nation:
1. Whether, or in what circumstances, a court may override an Act of Congress adopting a boundary for an Indian reservation, and set its own boundary.
2. Whether the Ninth Circuit erred by holding-in conflict with the decisions of this Court, including a decision involving the very boundary at issue-that the Reservation encompasses the area at issue.
