69  Allegations of Gross Misconduct 
69.1   Action by a Protest Committee
(a) When a protest committee, from its own observation or a report received from any source, believes that a competitor may have committed a gross breach of a rule, good manners or sportsmanship, or may have brought the sport into disrepute, it may call a hearing. The protest committee shall promptly inform the competitor in writing of the alleged misconduct and of the time and place of the hearing. If the competitor provides good reason for being unable to attend the hearing, the protest committee shall reschedule it.
(b) A protest committee of at least three members shall conduct the hearing, following the procedures in rules 63.2, 63.3(a), 63.4 and 63.6. If it decides that the competitor committed the alleged misconduct it shall either
(1) warn the competitor or
(2) impose a penalty by excluding the competitor, and when appropriate, disqualifying  boat, from a race or the remaining races or all races of the series, or by taking other action within its jurisdiction. A disqualification under this rule shall not be excluded from the boat’s series score.
(c) The protest committee shall promptly report a penalty, but not a warning, to the national authorities of the venue, of the competitor and of the boat owner. If the protest committee is an international jury appointed by the ISAF under rule 89.2(b), it shall send a copy of the report to the ISAF.
(d) If the competitor does not provide good reason for being unable to attend the hearing and does not come to it, the protest committee may conduct it without the competitor present. If the committee does so and penalizes the competitor, it shall include in the report it makes under rule 69.1(c) the facts found, the decision and the reasons for it.
(e) If the protest committee chooses not to conduct the hearing without the competitor present or if the hearing cannot be scheduled for a time and place when it would be reasonable for the competitor to attend, the protest committee shall collect all available information and, if the allegation seems justified, make a report to the relevant national authorities. If the protest committee is an international jury appointed by the ISAF under
rule 89.2(b), it shall send a copy of the report to the ISAF.
(f) When the protest committee has left the event and a report alleging misconduct is received, the race committee or organizing authority may appoint a new protest committee to proceed under this rule.
