Some of the cases also illustrate the fact, occasionally overlooked,
that, constitutionally speaking, the status of the States of Australia
is equal to, or co-ordinate with, that of the Commonwealth itself.
Sovereignty is not attributable to one authority more than to the
others ; it is divided between them in accordance with the demarca-
tion of functions set out in the Commonwealth Constitution. Within
the limits so prescribed, the legislative authority of the States is of
precisely equivalent quality and potency to that of the Common-
wealth, the authority of which is, in sees. 51 and 52 of the Common-
wealth Constitution, limited by reference to subject matter. In
short, the Commonwealth Parliament may legislate for " the peace,
order and good government of the Commonwealth with respect to"
a large number of subject matters. Similarly, the State of New
South Wales may legislate for the " peace, welfare and good govern-
ment" of New South Wales. In relation to such a subject matter
as that of taxation, and subject, of course, to any overriding pro-
vision of the Commonwealth Constitution, it is quite impossible to
deny to the States in relation to their geographical area constitu-
tional powers precisely analogous to those possessed by the Com-
monwealth Parliament in relation to its geographical area. The
legislation of the States cannot be deemed ultra vires merely because
of territorial reasons, unless analogous legislation of the Common-
wealth Parliament would similarly be deemed unconstitutional and
void. So far as concerns direct taxation, the States of Australia
occupy a constitutional position quite different from that of the
