Stapleton applied to the High Court of Australia for leave to appeal against his conviction on the following grounds :-
1. That the verdict was against the evidence and the weight thereof.
2. That there was misdirection, or non-direction amounting to misdirection, by the trial judge in that he (a) failed to direct the jury adequately or at all on certain of the evidence of one Sheila Peckham, a witness at the trial. (b) Failed to direct the jury adequately or at all on certain of the evidence of one Dr. Brothers, a witness at the trial. (c). Wrongly directed the jury that Dr. Brothers had said that the type of insanity he had been discussing was sometimes hereditary, whereas the witness had said that the mental abnormality from which the accused was suffering was hereditary and there was a history of insanity on both sides of his family.
3. That evidence was wrongly admitted. 4. That the trial judge failed to direct the jury adequately or at all on the use proper to be made of the evidence referred to in par. 3 (supra).
5. That there was a miscarriage of justice in that the accused's legal advisers were given no proper opportunity by the prosecution to consider the eligibility of the persons constituting the jury panel summoned for the trial to serve as jurors thereon.
During the hearing of the appeal, counsel for the applicant announced that he had been informed by the Crown authorities that it appeared that two of the jurors were not qualified, by reason of the fact that they were not British subjects.
A. L. Pickering, for the applicant-appellant. C. A. Sandery, for the respondent.
DIXON C.J. Leave to appeal is granted and it is ordered that the motion be treated as the appeal and heard instanter. The appeal is allowed, and there will be an order that the verdict and sentence be set aside and that there be a new trial. We shall give our reasons later.
