(1)  Where, before trial or at any stage of the trial, it appears to a judge that the statement of the crime or the particulars, or the name or description of any person or thing mentioned therein is or are defective or erroneous, he shall make such order for the amendment of the indictment as he thinks necessary to meet the circumstances of the case, unless, having regard to the merits of the case, the required amendment cannot be made without injustice.

(2)  Where an indictment is so amended a note of the order for amendment shall be endorsed on the indictment, and the indictment shall be treated for the purposes of the trial and of all proceedings in connection therewith as having been filed in its amended form.

(3)  Where, before trial or at any stage of the trial, it appears to a judge that an accused person may be prejudiced or embarrassed in his defence by reason of being charged with more than one crime in the same indictment, or that for any other reason it is desirable to direct that he should be tried separately for any one or more crimes charged in the indictment, the judge may order a separate trial of any count or counts in such indictment.

(4)  Where, before the trial or at any stage of the trial, it appears to a judge that the postponement of the trial of the accused person is expedient as a consequence of the exercise of any power of a judge under this section to amend an indictment, or to order the separate trial of a count, the judge shall make such order as to postponement of the trial as appears necessary.

(5)  Where an order is made for a separate trial or for the postponement of a trial –

(a) if such order is made during the trial the judge may order that the jury are to be discharged from giving a verdict on count or counts the trial of which is postponed or on the indictment, as the case may be;

(b) the procedure on the separate trial of a count shall be the same in all respects as if it had been charged in a separate indictment, and the procedure on the postponed trial shall be the same in all respects (if the jury have been discharged) as if the trial had not commenced; and

(c) the judge may make such order as to admitting the accused person to bail, and as to the enlargement of recognizances and otherwise, as the circumstances of the case may require.

(6)  The power conferred by this section shall be in addition to, and not in derogation of, any other power of the court for the same or similar purposes; and may before trial be exercised upon summons by a judge in chambers.
