In the course of its duties, the board of trustees will be called upon from time to time to interpret various provisions of the ordinance or statute which governs its conduct. The board will also be presented with various factual situations which do not lend themselves to easy interpretation. As a result, counsel to the board is responsible for issuing legal opinions to assist the trustees in performing their function in managing the trust. It is our practice to maintain an orderly system of the issuance of legal opinions so that they can form part of the overall body of law that guides the trustees. As changes in the law occur, it is our practice to update those legal opinions to ensure that the subjects which they cover are in conformance with the current state of the law.
