Concerning whether a college president could issue a letter of tenure and bind the college and its board of trustees by granting an administrative official tenure as a professor with a guaranteed salary position of 75 percent of whatever the previous administrative salary was without formal board approval or other board approval? Must there be board of trustees approval, formal or informal, of any contract for employment? In other words, for a contract to be properly ratified and become binding on the institution, must it be considered by the board of trustees at a duly called meeting? Can it be done in executive session without ever having it ratified in open session?
