Willful failure or refusal to testify as a witness after having been directed to appear at an Institute investigation or disciplinary proceeding, unless the testimony would tend to implicate the student in a violation of Institute regulations, or where the procedures governing the investigation or proceeding expressly grant a right of non-participation; or knowingly providing false testimony or evidence at an Institute disciplinary proceeding. An Institute disciplinary proceeding includes, but is not limited to, formal or informal action by the offices of the Dean of Students, hearings before any Judicial Hearing Board described in this Handbook or in Institute policies such as the Sexual Misconduct Policy, and procedures adopted by the Trustees in connection with the Rules for Maintenance of Public Order.
