Whether that law is part of the Common Law of Australia
or not is a question which I should be very sorry to decide
without much fuller argument than has been possible on this
occasion. I say this because there are very weighty authorities to
the effect that Parliamentary law is not introduced into the
colonies, and therefore not into the Commonwealth. I refer to
the opinion of Sir A. Cockburn, A.G., and Sir R. Bethell, S.G.,
(Feb. 15, 1856, quoted in Forsyth's Cases and Opinions on Con-
stitutional Law, at p. 25), and the decision of the Privy Council
in Kielly v. Carson, (1843) 4 Moo. P.C., 84. We are fortunately
relieved from the necessity of determining that point. All we have
to decide is whether, under the provisions of the Statute Law
before us, a candidate is incapable of election if he has committed
one of the acts prohibited by the Commonwealth Electoral Act.
On this question two lines of argument commend themselves to
my mind, each of which leads to the same result. One is the
general rule, stated in many forms, that, when a Statute creates
a new obligation or imposes a new duty, and preseribes specific
consequences or remedies for non-performance of the duty or
breach of the obligation, those remedies must be adopted and no
other. Now, in this case the Legislature has enacted a number
of provisions, and has attached to the breach of some of them
liability to imprisonment for 12 months, and the Constitution
had already provided that a person subject to punishment of that
kind should lose his seat. So that, from that point of view, it
would appear that Parliament was aware that any person guilty
of any of those offences to which the punishment of 12 months
imprisonment was attached would lose his seat under the Con-
stitution, and that therefore it was unnecessary to make further
provision in the Electoral Act, leaving his guilt to be established
in the ordinary way. Another and perhaps a wider argument is
this: - The Commonwealth was formed by the union of six separate
States. Now, in all those States there had been electoral laws
which, after the establishment of the Commonwealth, continued to
be the law of the Commonwealth as to the respective States until
this Commonwealth electoral law was passed. The earliest was
that of New South Wales. Now, in the Act of the Legislative
Council, passed before Responsible Government was established,
