A no-contact order in a college sexual misconduct case is just as it sounds. It means when an order is issued a student would not allow to have contact with say another party. Schools as a routine matter, generally do impose no-contact orders when there's an allegation of sexual misconduct, say if the complainant or to make an allegation to the school, the school just in an abundance of caution would, in most instances, impose a no-contact order against the respondent. This is just to try to avoid future issues.
A no-contact order can create its own problems where if there's say, alleged violations of the no-contact order, the respondent could get into further trouble. Yet sometimes it's a mutual where the expectation would be that both parties have the same obligation or expectation to not contact each other. In many instances, it's actually one side where only respondent cannot contact the other party.
You can't expect the school to be looking out for your interests if you're accused in a sexual misconduct case, you need to have an experienced attorney advisor help you understand all considerations, including whether a no-contact order is appropriate or how it should best be addressed if one is imposed.
