Yes, the university should discipline male students accused of sexual assault when no criminal charges are filed. The university setting should be a safe place for female students to be free of sexual assault. There can be a number of reason that charges are not filed in sexual assault cases.
If someone has not been charged with harassment they are not guilty. They should not be defaced for something that was not proven, there is a reason our court operates under "Innocent until proven guilty" and that is because the person is innocent until proven guilty. Do not convict an innocent man, and also I love how the question specified men, if they did to men they would have to do the same to women.
In the criminal justice system of the United States, a person accused of a crime is innocent until proven guilty. Therefore, it is not fair to punish the person accused of sexual assault when no evidence is able to be brought forth. Universities should not deal with issues as complicated as sexual assault and should instead leave such proceedings to local police.
I do not believe that universities should impose discipline when no criminal charges are made. It is all United States citizens' right to being innocent until proven guilty. In a situation where in the eyes of the law, no crime was committed and it is only an accusation. An accusation is not an admit of guilt or an invitation for discipline where it might not be necessary.
Universities should not impose punishment for sexual assault when no criminal charges are involved. Sexual assault is a criminal matter and should be addressed through the legal system. Universities taking the law into their hands is not acceptable. Everyone should be entitled to the due process of the law. Without due process there is no justice.
