(1) If at any time in the course of the trial after the court has been sworn and before the finding, the trial judge advocate is satisfied that there is a varience in unessential details between the charge or charges and the evidence adduced in support thereof, the trial judge advocate may amend the charge or charges accordingly provided that-
(a) no evidence which could not have been given in support of the original charge shall be given in support of the substituted charge;
(b) the accused shall not be substantially prejudiced by the making of such amendment in the conduct of his defence; and
(c) the court shall, if so requested by the accused adjourn for a reasonable time to enable him to meet the charge or charges as so amended.
(2) All such amendments shall be noted in the minutes at the point at which such amendments shall be made, and shall be verified on the original documents by the signature of the trial judge advocate.
