This bill provides a process by which the Confederated Tribes of the Grand Ronde Community of Oregon and Oregon may negotiate to amend or replace the existing agreement defining the tribe's hunting, fishing, trapping, and animal gathering rights. The current agreement, which was made effective by a January 12, 1987, consent decree by the U.S. District Court for the District of Oregon, serves as the exclusive and final determination of the tribe's hunting, fishing, trapping, and gathering rights. This bill instead allows a December 2, 1986, agreement between the United States, Oregon, and the tribe (known as the Grand Ronde Hunting and Fishing Agreement) to define the tribe's rights until and unless it is amended or replaced upon mutual agreement of the tribe and Oregon. The bill allows the tribe and Oregon to return to the U.S. District Court for the District of Oregon to request the modification or termination of the January 12, 1987, consent decree. The bill prohibits a new or amended agreement from (1) affecting the other rights of the tribe or any other Indian tribe, (2) limiting Oregon from entering into separate agreements with other tribes to address the authority to take species within the geographic scope of the agreement, or (3) being used in a civil or criminal action to modify any treaty or other right of a tribe.
