Non-consensual sex in a college sexual misconduct case is as the name implies, but it's more nuanced than that. Non-consensual sex, the non-consent part would be or could be dictated by either lack of consent because of incapacitation or a lack of consent because the respondent, the accused party, that is, did not obtain a consent either verbally or physically from the accusing party, the complainant, that is.
Non-consensual sex is just that. It's sex without obtaining the other person's consent, either because consent could not be obtained because the party, say, was incapacitated or because there is an allegation that consent was just not simply obtained because the complainant or the person who's making the allegation would allege that they did not provide consent for whatever various reason.
So much is at stake if you're accused of non-consensual sex in a college sexual misconduct case, so you have to make sure that your interests are protected. An experienced attorney advisor can do so and should be involved from as early as possible in the process.
