The text outlines the jurisdiction of the Indian Claims Commission, as provided by H.R. 4497, which became Public Law 726. The Commission is responsible for hearing and determining claims against the United States on behalf of Indian tribes, bands, or other identifiable groups. Claims can include those related to treaties, contracts, breach of duty, land takings, and fair dealings. The Commission will apply legal principles and make deductions for any payments made by the United States. Claims accruing after the approval of the Act will not be considered, and all defenses will be available to the United States. The Commission will consider counterclaims, set-offs, and funds expended for the benefit of the claimant when determining relief.
