EVATT J. I agree. On 26th March 1936 when the appellant answered the charge contained in the indictment by pleading not guilty, he became entitled to have the question of guilt determined by the unanimous decision of a jury of twelve. The only question before us is whether, in August, 1936, when the principle of unanimity in criminal cases was abrogated in Tasmania, the Act used terms sufficiently clear to show that it operated to deprive the appel- lant of his pre-existing right to a unanimous decision. It was argued that, in criminal issues, unanimity, as opposed to majority, decision is a mere matter of procedure. But this argument is answered by the fact that in Tasmania, as elsewhere in common-law countries, trial by jury has been universally regarded as a funda- mental right of the subject, and unanimity in criminal issues has been regarded as an essential and inseparable part of that right, not a subordinate or merely procedural aspect of it (Cf. Stephen, History of the Criminal Law of England (1883), vol. I., pp. 304, 305 Ford v. Blurton 1, per Atkin L.J.; R. v. Armstrong 2, per Hewart L.C.J. Australian Law Journal, vol. 10, Supplement, p. 64).
In the United States, the principle of unanimity has been treated as an integral part of the constitutional guarantee of the jury system, and a similar guarantee (in respect of offences against the laws of the Commonwealth) is contained in sec. 80 of the Commonwealth Constitution. For the Supreme Court of the United States, Brewer J. said, in American Publishing Co. v. Fisher 3 :-
"Now unanimity was one of the peculiar and essential features of trial by jury at the common law. No authorities are needed to sustain this proposition. Whatever may be true as to legislation which changes any mere details of
jury trial, it is clear that a statute which destroys this substantial and essential feature thereof is one abridging the right. It follows, therefore, that the court erred in receiving a verdict returned by only nine jurors, the others not concurring." In view of this overriding principle, which cannot be overlooked on the question of construction, the better interpretation of the
