Former criminal prosecutor here. I've represented both victims of sexual assault and persons accused of it on the FSU campus in Title IX hearings. I was a witness after the fact to a rape at TU of a former girlfriend while I was a student. So, I've got a good handle on campus rape, the adjudicatory process for campus misconduct involving sex, athlete issues, and the applicable federal and state laws.
There are lots of problems with this case based on what is in that report, some of which are factual and others are procedural.
First, there is the standard of proof. The tribunal is clearly confused between evidentiary burdens and evidentiary conclusions. The evidentiary burden standard in the hearing is "a preponderance of the evidence". Which means "the greater weight of the evidence" This is the standard in civil court. However, what tribunals like this one don't know or refuse to acknowledge, and it's a frequent error, even with experienced academic (and not trial) lawyers advising these tribunals, is that the preponderance of evidence is based on a comparison of the probable truth and accuracy of the evidence presented, not the amount of evidence. On numerous occasions the report says something to the effect of: "she doesn't remember and was scared. He refused to answer the question. Therefore her version is conclusively proven". That is fine for some material facts to be concluded, but only when there is additional evidence supporting that inference. I don't see any in the report and they don't mention it. In other words, if you accuse me of A, and I refuse to say A is A and decline to answer why A isn't B, you can't automatically conclude that A is A, unless there is some other evidence, other than our testimony, that A is A. With the exception of some of the witness statements regarding the conduct of A5, there is simply no evidence she did not consent to sexual contact. Indeed, the absence of forensic evidence in the rape trauma protocol, which is glossed over in the report, directly contradicts her assertions of repeated rough sex. While it is permissible to draw conclusions from the silence of the players in the proceeding, you can't conclude that she is telling the truth simply because they are silent or there is conflicting testimony from them. Conversely, you cannot conclude that consent did not occur when substantive evidence of consent is offered by the accused but the accuser refuses to consent to the disclosure of that evidence.
Which brings me to the videotape. It's a felony in Minnesota to videotape someone in a private place like a bedroom with the intent to commit an act that could result in civil liability. In this case, it can be proven he filmed the sex act with the intent to disclose it to third parties. Public disclosure of private facts is a tort in MN. In regular people speech, most people know that truth is a defense to libel. But you can still be ordered to pay damages if you disclose facts that are damaging to a person's reputation if those are facts that an ordinary person would normally not disclose. So even if she consented to an unusually large number of sex partners, it may still be a tort to disclose the tape of it, even if she consented to the taping. ( In this case, it's clear at times that she understood she was being taped and consented to it. It's one of the more damaging parts of her story).
Even if he only intended to watch it himself, uploading it on the phone discloses the images to the phone provider and others with access to his phone, as well as anyone he sends it to, (the app creator and the recipients he sends it to).
So they are absolutely correct in demanding that she consent in writing to the further disclosure of the tape.
I've got more to say on this case, but I'm out of time right now. What the players are doing is absolutely wrong. But what happened in this case is absolutely flawed. It's an emotional response to conclude rape occurred here by anyone other than A5 and that's a jury question, not an academic adviser with no legal training, who is inherently vulnerable to bias and influence.
