Section 64 Notice
If a question is to be raised in any proceedings on indictment (other than proceedings on appeal) notice of intention to do so shall be given to the court before which the trial is to take place and to the other parties not later than 15 days after service of the indictment.
The notice shall be recorded on the record copy of the indictment or in the record of proceedings, as the case may be, and the court, in chambers, shall reserve consideration of the question to the trial diet.
The court may order that witnesses and jurors are not cited to attend at the trial diet.
At the trial diet the court, after hearing parties, may determine the question or may decide that a preliminary ruling should be sought.
If the court determines the question the accused shall then (if appropriate) be called upon to plead to the indictment, and without prejudice to any other power available to it, the court—
may prorogate the time for lodging any special defence;
may continue the diet to a specified time and place;
in a case where witnesses and jurors have not been cited to attend at the trial diet, shall continue the diet and order the citation of witnesses and jurors to attend the continued diet.
No period during which the diet is continued under paragraph (5) shall—
subject to paragraph (7), be longer than 21 days;
be taken into account for the purposes of determining whether any time limit has expired.
The court may on the application of the prosecutor or the defence extend any period during which the diet is continued for such longer period than 21 days as it thinks fit, on special cause shown.
