The main purpose of the Tribal Warrant Fairness Act is to enable the U.S. Marshals Service to provide assistance in criminal matters involving Tribal jurisdictions. This legislation aims to enhance cooperation between federal law enforcement and Tribal authorities, ensuring that justice is effectively served in cases that involve Indigenous communities. Key provisions of the Act include amendments to existing laws that expand the role of the U.S. Marshals Service. Specifically, the Act allows the Marshals Service to assist with "Tribal fugitive matters" when requested by an Indian Tribe.
