Developments in criminal law and criminal justice

Conclusion

It follows from what has been said above that history, principle, and authority combine to compel the conclusion that § 80's guarantee of trial by jury precludes a verdict of guilty being returned in a trial upon indictment of an offence against a law of the Commonwealth otherwise than by the agreement or consensus of all the jurors. That being so, § 57 of the Juries Act, 1927, cannot, consistently with § 80, operate to authorize the conviction of either of the appellants by a majority verdict. Their convictions were unconstitutional and must be set aside.

The appeal should be allowed. The orders of the South Australian Court of Criminal Appeal should be set aside and in lieu thereof it should be ordered, in the case of each appellant, that the appeal to that court be allowed, that the conviction be quashed and a new trial ordered.
