“We shall confine ourselves to reminding the Crown that the jurisdiction which permits a second re-trial after two jury disagreements in circumstances like the present must be exercised with extreme caution. The broad public interest in the administration of criminal justice leads us to the clear view that a second re-trial should be confined to the very small number of cases in which the jury is being invited to address a crime of extreme gravity which has undoubtedly occurred (as here) and in which the evidence that the defendant committed the crime (again, as here) on any fair minded objective judgment remains very powerful.”
