To amend the Act of June 18, 1934, to reaffirm the authority of the Secretary of the Interior to take land into trust for Indian tribes, and for other purposes.

This bill amends the Indian Reorganization Act to make it applicable to all federally recognized Indian tribes, regardless of when a tribe became recognized. The amendments made by this bill are retroactively effective as if included in the Indian Reorganization Act. (This effectively overrules the Supreme Court's decision in Carcieri v. Salazar, which held that the Department of the Interior could not take land into trust for a specified tribe because that tribe had not been under federal jurisdiction when the Indian Reorganization Act was enacted.)
