2. In the Rules of Procedure (Air Force) 1972(1), in rule 9(d), for the words which the accused is to be asked there shall be substituted the following words:
“Do you wish to say anything? You do not have to say anything but it may harm your defence if you do not mention now something which you later rely on in court. If you do wish to say anything, it must be evidence given on oath. Any evidence you give will be taken down in writing and may be given in evidence in court.”.
