(1)If it appears to the court that a jury to try any issue before the court will be, or probably will be, incomplete, the court may, if the court thinks fit, require any persons who are in, or in the vicinity of, the court, to be summoned (without any written notice) for jury service up to the number needed (after allowing for any who may not be qualified under section 1 of this Act, and for refusals and challenges) to make up a full jury.
(2)The names of the persons so summoned shall be added to the panel and the court shall proceed as if those so summoned had been included in the panel in the first instance.
