This legislation, titled the Tribal Warrant Fairness Act , aims to enhance the ability of the U.S. Marshals Service to provide assistance in criminal matters involving Indian Tribes. It achieves this by amending federal statutes to explicitly include Tribal law enforcement and jurisdiction within the Marshals' scope of operations. Specifically, the bill modifies section 566(e)(1) of title 28, United States Code, to allow the U.S. Marshals Service to assist in Tribal fugitive matters when requested by an Indian Tribe. Furthermore, it amends the Presidential Threat Protection Act of 2000 to include Indian Tribes and Tribal law when referring to law enforcement components and applicable laws, thereby expanding threat protection efforts to encompass Tribal entities.
