34 C.F.R. § 106.71 – Retaliation.

(a) Retaliation prohibited. No recipient or other person may intimidate, threaten, coerce, or discriminate against any individual for the purpose of interfering with any right or privilege secured by title IX or this part, or because the individual has made a report or complaint, testified, assisted, or participated or refused to participate in any manner in an investigation, proceeding, or hearing under this part. Intimidation, threats, coercion, or discrimination, including charges against an individual for code of conduct violations that do not involve sex discrimination or sexual harassment, but arise out of the same facts or circumstances as a report or complaint of sex discrimination, or a report or formal complaint of sexual harassment, for the purpose of interfering with any right or privilege secured by title IX or this part, constitutes retaliation. The recipient must keep confidential the identity of any individual who has made a report or complaint of sex discrimination, including any individual who has made a report or filed a formal complaint of sexual harassment, any complainant, any individual who has been reported to be the perpetrator of sex discrimination, any respondent, and any witness, except as may be permitted by the FERPA statute, 20 U.S.C. 1232g, or FERPA regulations, 34 CFR part 99, or as required by law, or to carry out the purposes of 34 CFR part 106, including the conduct of any investigation, hearing, or judicial proceeding arising thereunder. Complaints alleging retaliation may be filed according to the grievance procedures for sex discrimination required to be adopted under § 106.8(c).
(b) Specific circumstances.
1. (1) The exercise of rights protected under the First Amendment does not constitute retaliation prohibited under paragraph (a) of this section.
2. (2) Charging an individual with a code of conduct violation for making a materially false statement in bad faith in the course of a grievance proceeding under this part does not constitute retaliation prohibited under paragraph (a) of this section, provided, however, that a determination regarding responsibility, alone, is not sufficient to conclude that any party made a materially false statement in bad faith.
