This bill authorizes the South Dakota State Brand Board to enter into a memorandum of understanding with any federally recognized Indian tribe for the purpose of investigating cattle theft. The cooperation is specifically aimed at addressing livestock theft that occurs on or near tribal lands, and the agreement can only be established if the tribal government provides authorization.

The new section added to chapter 40-18 outlines the conditions under which the Brand Board can collaborate with tribal authorities, emphasizing the importance of mutual agreement and cooperation in tackling the issue of cattle theft in these areas. This initiative aims to enhance law enforcement efforts and strengthen relationships between state authorities and tribal governments.
