This legislation, titled the Tribal Regulatory Reform Implementation Act of 2026, amends the Indian Tribal Regulatory Reform and Business Development Act of 2000. Its core provision is to transfer all administrative responsibilities and jurisdiction related to the Authority established by the 2000 Act. Effective upon enactment, these duties, previously held by the Secretary of Commerce, will be assigned to the Secretary of the Interior . This aims to consolidate federal oversight of tribal regulatory reform and business development initiatives under the Department of the Interior, aligning these functions with its broader role in federal-tribal relations.
