that decisions of a Court where there is no active controversy be-
tween interested parties are not so valuable as when there is such
controversy ; and that, when a litigated case comes before the Court
subsequently, the Court would approach it with prejudiced minds,
But this argument is an argument of expediency, and is not for us,
It may be that we shall have in the future attempts at preventive
law as well as at preventive medicine ; and that, on a balance of
expediencies, the law-makers may prefer judicial proceedings before
acting, rather than to keep all judicial proceedings till after the
doubtful step has been taken, The point is that the Constitution
does not expressly forbid the vesting of other powers in this Court,
and that there is no necessary implication to that effect. In the
next place, I think that an application under Part XII. does come
(if that is necessary) within the words of sec. 76, " matter atising
under this Constitution, or involving its interpretation." Counsel
for the State of Victoria says that "matter" in this contest means a
"claim of right": but this definition is too broad, I think, in that
it omits the idea of some curial proceeding; and too narrow, in
that it assumes that there must be a contest between parties. It is
not necessary that a "matter" should be between parties. I
pass by the fact that in the Judiciary Act itself, " matter" includes
any proceeding in a Court "whether between parties or not" ; for
it may be urged that the Act was not in force at the time of the
Constitution. But in the English Judicature Act 1873 the word
"matter" is defined as "every proceeding in the Court not in a
cause" ; and "cause" includes "any action, suit, or other original
proceeding between a plaintiff and a defendant." This is the language
of the Parliament which enacted our Constitution ; and the distine-
tion between " causes" and "matters" or " suits " and " matters"
was common in still earlier legislation (15 & 16 Vict. c. 80; 15 &
16 Vict. c. 86; General Orders of 1841). In the Oxford Dictionary
the meaning of " matter," as used in law, is " something which is
to be tried or proved." It may be that the connotation of words
used in the Constitution may not be extended by Parliament; but
surely not the denotation. The Constitution does not stereotype
the denotation of words for all subsequent time. The States can
create new matters. Any State may hereafter adopt the French
