Can the University retaliate against someone for filing an unlawful gender-based discrimination complaint, or for participating in an investigation?

No. Retaliation is prohibited by university policy 5-16.2 (5). Retaliation against an individual who reports or complains of unlawful gender-based discrimination or who provides information in a sexual misconduct investigation or proceeding is prohibited. If you have participated in an unlawful gender-based discrimination investigation and feel that you have been retaliated against, inform the Title IX Coordinator immediately. Any allegations of retaliation will be promptly investigated and will result in disciplinary action if substantiated.
