Rh : of punishing or otherwise dealing with the accused and other powers as the court before which he was tried would have had if the jury had come to the substituted verdict;
 * (b) in any other case, the Court of Criminal Appeal shall substitute for the verdict of the jury a verdict of acquittal:

Provided that where the offence mentioned in paragraph (a) is one for which the sentence is fixed by law, the sentence shall (whatever the circumstances) be one of imprisonment for life.

(2) The term of any sentence passed by the Court of Criminal Appeal in the exercise of the powers conferred by subsection (1)(a) of this section shall, unless the court otherwise direct, begin to run from the time when it would have begun to run if passed in the proceedings in the court before which the accused was tried.

In relation to a person sentenced to Borstal training, the reference in this subsection to the term of a sentence shall be construed as a reference to the periods during which, under the Prison Act 1952, he may be detained in a Borstal institution.

4.—(1) Where on the trial of a person the question arises (at the instance of the defence or otherwise) whether the accused is under disability, that is to say under any disability such that apart from this Act it would constitute a bar to his being tried, the following provisions shall have effect.

(2) The court, if having regard to the nature of the supposed disability the court are of opinion that it is expedient so to do and in the interests of the accused, may postpone consideration of the said question (hereinafter referred to as “the question of fitness to be tried”) until any time up to the opening of the case for the defence, and if before the question of fitness to be tried falls to be determined the jury return a verdict of acquittal on the count or each of the counts on which the accused is being tried that question shall not be determined.

(3) Subject to the foregoing subsection, the question of fitness to be tried shall be determined as soon as it arises.

(4) The question of fitness to be tried shall be determined by a jury; and—
 * (a) where it falls to be determined on the arraignment of the accused, then if the trial proceeds the accused shall be tried by a jury other than that which determined that question;
 * (b) where it falls to be determined at any later time it shall be determined by a separate jury or by the jury by whom the accused is being tried, as the court may direct.
