3.—(1) If it is represented to the Establishment Committee by the chief executive officer that an officer has been guilty of misconduct or neglect of duty and the Establishment Committee is of the opinion that the subject of the complaint is not serious enough to warrant proceedings under regulation 4 with a view to the dismissal or reduction in rank of the officer, the Establishment Committee may cause an investigation to be made into the matter in such manner as it thinks fit, and the officer shall be informed in writing of the case against him and shall have a reasonable opportunity of replying thereto.
(2) The Establishment Committee may, after considering the case made against the officer, his reply thereto and the results of the investigation, if any, and, if it is of the opinion that the allegation has been proved, impose a penalty such as stoppage or deferment of increments, fine or reprimand, or a combination of such penalties.
