No, the final decision is made for the University by the University Appeals Board, which is a committee of the University Senate. The President does have the authority to ask a hearing panel or appeals board to rehear or reconsider a case. He or she may make recommendations and offer advice to resolve the case. Cases that are handled informally are often resolved within a couple of weeks. Any time a formal hearing is required, the process takes longer.
All parties have the right to investigate the case.
It takes time to arrange for a day when all the parties and the hearing panel are available. The accused student then has the right to at least 10 days notice before the hearing actually takes place. That whole process often takes 4-6 weeks. Once a decision is made, the student then has ten days to file a notice of appeal. Getting materials prepared and the Appeals Board scheduled to meet typically takes about a month.
