The administrator organizing the hearing acknowledged that those statements should have been redacted because they were not testimony germane to whether a sexual assault had occurred. (Under the new system, an outside lawyer decides what will be allowed as evidence.)

After the second five-member panel came back 3-2, the accuser appealed again. She asked that Stanford’s Office of Community Standards “issue a no-contact order to protect me” from the accused. One had been in place throughout the months of proceedings. On at least two occasions, the football player had to be asked to leave parties by a resident dean — and on another, by campus security — because of his apparently violating that order, both the accuser and the accused acknowledged in statements.

“The past nine months of my life have been the worst of my life,” she wrote to Greg Boardman, Stanford’s vice provost for student affairs, on Oct. 20, 2015, as part of her appeal. “I’ve experienced fear, anxiety, depression, self-doubt, and hatred in ways I never imagined during the first 20 years of my life. An introduction to someone new in early February turned into my worst nightmare — every woman’s worst nightmare.”

Her appeal for a third hearing and a no-contact order was denied, without explanation.

Stanford said that it accommodates accusers even after their cases come up short. They can secure special housing arrangements or even escorts to certain parts of campus. But officials said that they could not impose anything that looked like penalties, even for safety reasons, on those who are found not responsible — even if the vote found by 3-2 or, now, 2-1 that sexual assault had occurred.

“I think you would face legal liability to that person if after that process he was told, ‘You can’t be in this part of the campus,’” said Ms. Karlan, the law professor who is chairwoman of the sexual assault advisory committee.

The woman is trying to decide whether to return to campus or pursue her degree elsewhere. She said that she loved the school and that she was never happier than in her time there. She is worried about encountering the football player if she returns to campus.

“But do I have to leave Stanford to feel safe?” she said. “I’m certain that this isn’t the way the Title IX process was meant to work.”
