The Tribal Law and Policy Institute (TLPI), with funding from the Department of Justice (DOJ), organized the development, implementation, and facilitation of the Mentor Court Program. The primary goal of the program was to manage and implement a Tribal Healing to Wellness Court (THWC) Tribally specific mentor court program for tribal justice systems including tribal veterans’ treatment courts, with a focus on tribal-inclusivity, culturally relevant selection criteria, and peer-to-peer exchange of information between Mentor Court programs and Sister Court programs. The relationship between Mentor Courts and Sister Courts is representative of the interconnectedness of indigenous peoples and the significance of shared knowledge. We believe that the Mentor Court/Sister Court model promotes Tribal sovereignty and self-determination within Indigenous justice systems.
