In order to make the principles stated in the preamble of the Board of Trustees bylaws effective and to fulfill the mission of the university, the Board of Trustees has established policies for the direction of Michigan State University. The policies set forth the Board's position on issues which are vital to the university. Although Board policy is reprinted and interpreted in several official university publications, the statements of these policies herein, in the event of any conflict or questions, are authoritative and controlling. They may be amended only by formal Board of Trustees action. The Board delegates to the president the authority to implement and interpret these policies and, in order to do so, authorizes him or her to promulgate further university policies that are consistent with the policies of the Board of Trustees.
