Where a diet has been fixed in a summary prosecution, it shall be competent for the court, on a joint application in writing by the parties or their solicitors, to discharge the diet and fix an earlier diet in lieu.

Where the prosecutor and the accused make joint application to the court (orally or in writing) for postponement of a diet which has been fixed, the court shall discharge the diet and fix a later diet in lieu unless the court considers that it should not do so because there has been unnecessary delay on the part of one of more of the parties.

Where all the parties join in an application under subsection (2) above, the court may proceed under that subsection without hearing the parties.

Where the prosecutor has intimated to the accused that he desires to postpone or accelerate a diet which has been fixed, and the accused refuses, or any of the accused refuse, to make a joint application to the court for that purpose, the prosecutor may make an incidental application for that purpose under section 134 of this Act; and after giving the parties an opportunity to be heard, the court may discharge the diet and fix a later diet or, as the case may be, an earlier diet in lieu.

Where an accused had intimated to the prosecutor and to all the other accused that he desires such postponement or acceleration and the prosecutor refuses, or any of the other accused refuse, to make a joint application to the court for that purpose, the accused who has so intimated may apply to the court for that purpose; and, after giving the parties an opportunity to be heard, the court may discharge the diet and fix a later diet or, as the case may be, an earlier diet in lieu.
