"It is proper, at the outset, to observe that this case does
not involve any prerogative 'in the sense of the word', to
use the phrase employed by the Privy Council in Theodore v.
Duncan
(1919) AC 696, at p 706
, 'in which it signifies the power of the Crown
apart from statutory authority'. Though much of the argument
addressed to us on behalf of the States rested on the prerogative,
this distinction was not observed, but it exists, and, so far as
concerns prerogative in the sense indicated, it is unnecessary
to consider it. In several recent cases the Judicial Committee
has had the broader question under consideration, as in
Canadian Pacific Railway Co. v. Toronto Corporation
(1911) AC 461
and Bonanza Creek Gold Mining Co. v. The King
(1916) 1 AC 566
,
but in none of these was it found necessary to determine it.
It is manifest that when such a question is involved in a
decision, the nature of the prerogative, its relation to the
Government concerned, and its connection with the power
under which it is sought to be affected, may all have to be
considered. In the Bonanza Creek Case
(1916) 1 AC, at p 587
Lord Haldane,
speaking for the Privy Council, after favouring an
interpretation
of the British North America Act by which certain
rights and privileges of the Crown would be reserved from
Canadian legislative power, proceeded to say : - 'It is quite
consistent with it' (that interpretation) 'to hold that executive
power is in many situations which arise under the statutory
Constitution of Canada conferred by implication in the grant
of legislative power, so that where such situations arise the
two kinds of authority are correlative. It follows that to this
extent the Crown is bound and the prerogative affected.'
In this case we have to consider the effect of certain statutory
authority of the States, but in relation to pl. xxxv. only, and
it is necessary to insert a word of caution. If in any future
case concerning the prerogative in the broader sense, or arising
under some other Commonwealth power - for instance,
taxation,
- the extent of that power should come under
consideration
so as to involve the effect of the principle stated in the
passage just quoted from the Bonanza Creek Case, and its
application to the prerogative or to the legislative or executive
power of the States in relation to the specific Commonwealth
power concerned, the special nature of the power may have
to be taken into account. That this must be so is patent from
the circumstance that the legislative powers given to the
Commonwealth Parliament are all prefaced with one general
express limitation, namely, 'subject to this Constitution',
and consequently those words, which have to be applied
seriatim to each placitum, require the Court to consider with
respect to each separate placitum, over and beyond the general
fundamental considerations applying to all the placita, whether
there is anything in the Constitution which falls within the
express limitation referred to in the governing words of s. 51.
That inquiry, however, must proceed consistently with the
principles upon which we determine this case, for they apply
generally to all powers contained in that section."
