Looked up the USFS Rulebook, available here:
http://www.usfsa.org/content/2017-18 Rulebook.pdf
From pages 17 to 19:
Section 3 Grievance and Disciplinary Proceedings. All grievance and disciplinary procedures must be filed and resolved pursuant to the procedures outlined in this section and in the Grievance Committee Rules and Ethics Committee Rules. The forms and instructions for filing a grievance are available from U.S. Figure Skating headquarters upon request of a member or member club.
A. Grievance Proceedings
(Except for matters subject to the jurisdiction of the United States Center for Safe Sport under Section 4 of this article):
(i) Scope:
(a) Any U.S. Figure Skating member or member club aggrieved or harmed by the alleged violation of a U.S. Figure Skating bylaw or rule by any other U.S. Figure Skating member or member club may bring a grievance citing the alleged violation of the U.S. Figure Skating bylaw or rule.
(b) The member or member club must be a member in good standing both at the time the grievance is filed and at the time of the alleged violation of the U.S. Figure Skating bylaw or rule.
(c) Such grievance must include the allegation that violation of a specific U.S. Figure Skating bylaw or rule caused harm to the Grievant.
(ii) Time period: A grievance must be filed:
(a) Within 60 days of the occurrence of the alleged violation, or
(b) Within 60 days of the discovery of the alleged violation, or
(c) In the case of a minor, within 60 days after the minor’s 18th birthday, whichever is later."
Section 4 Safe Sport – Sexual Abuse or Misconduct.
The investigation and adjudication of matters involving allegations or reports of sexual abuse or misconduct, or other violations of U.S. Figure Skating’s SafeSport Policies that involve prohibited conduct that is reasonably related to and accompanies an alleged violation involving sexualized behavior (see, GR 1.03, U.S. Figure Skating Policy Statement on Harassment and Abuse, and the current edition of the U.S. Figure Skating SafeSport Program Handbook) are subject to the jurisdiction of the United States Center for Safe Sport (“USCSS”) in accordance with the requirements of the USOC and as set forth in the USCSS Bylaws or other USCSS governing documents. Rules and procedures to be followed by U.S. Figure Skating and its members and member clubs in dealing with allegations or reports 19 of sexual abuse or misconduct, or other violations of U.S. Figure Skating’s SafeSport Policies that fall within the jurisdiction of the USCSS, and the enforcement of discipline or other sanctions issued by the USCSS, are set forth in the applicable SafeSport policies and disciplinary procedures of the USCSS, GR 1.03 and/or other rules of U.S. Figure Skating
So it looks like the 60 day thing may have been their old policy and now everyone is under SafeSport guidelines. But we know that is not infallible either given the ongoing issues as USAGym, USASwim, etc.
