"The common law doctrine as to the effect of a verdict of
acquittal is too well settled to require exposition, and it
is too late to inquire into its origin. If it had been
intended by the framers of the Constitution to abrogate that
doctrine in Australia, and to confer upon the High Court a
new authority, such as had never been exercised under the
British system of jurisprudence by any Court of either
original or appellate jurisdiction, it might have been
anticipated that so revolutionary a change would have been
expressed in the clearest language. To adopt the words of
Sir Peter Maxwell (founded upon the language of Marshall CJ
in United States v Fisher [1805] USSC 18; 2 Cranch, 358, at 390, 'it is in
the last degree improbable that the Legislature would
overthrow fundamental principles ... or depart from the
general system of law, without expressing its intention with
irresistible clearness, and it would therefore be absurd to
give any such effect to general words, simply because in
their widest and most abstract sense they admit of such an
interpretation' (Maxwell on Statutes, 1st ed, 66). So far
from finding any such clear indication in the Australian
Constitution, I find a clear indication of a contrary
intention. Sec 80 lays down as a fundamental law of the
Commonwealth that the trial on indictment of any offence
against any of the laws of the Commonwealth shall be by
jury. The framers of the Constitution, the electors who
accepted it, and the Parliament which enacted it, must all
be taken to have been aware of the absolute protection
afforded by a verdict of not guilty under the common law of
all the States. With this knowledge they thought proper to
enact that any indictable offence that might be created by
the new legislative authority established by the
Constitution should also be tried by jury. The history of
the law of trial by jury as a British institution (not
forgetting the Act called Fox's Libel Act) is, in my
judgment, sufficient to show that this provision ought prima
facie to be construed as an adoption of the institution of
'trial by jury' with all that was connoted by that phrase in
constitutional law and in the common law of England."
