to it within its proper ambit, I think that its ambit is entirely
clear of the sections of the old Act preserved by see. 8 for the
purposes expressed in that section. What are the decisions the
validity of which is not to be challenged by prohibition or other-
wise? I do not see why they should be taken to include
decisions under sec. 8 unless they are necessarily part of its
subject matter. There are a number of provisions in the Act by
which the Industrial Court is empowered to deal, originally or on
appeal from a Board, with matters arising under the Act itself,
irrespective of the Industrial Arbitration Act (sce secs. 14, 16,
26, 38, 39, 41, 42, 43, 44, 45, 46, 50, 55 and 60). I think the
"decisions " meant in sec. 52 are those which are given by virtue
of these sections, and which do not involve the determination of
controversies existing before the Act was passed. Such a construc-
tion satisties the meaning of the term in sec. 52, and with this
subject matter for its operations it is not necessary to construe,
and unless of necessity I ought not to construe, the section as
extending to proceedings instituted under the old Act. Thus the
provisions are harmonized. A just and reasonable field of opera-
tion is given not only to sec. 52, but to sec. 8, and also, for the
purposes of that section, to as many of the " enactments " of the
Industrial Arbitration Act as would certainly have applied had
the proceedings been carried to a conclusion before its expiration.
I am of opinion, therefore, that in the present case the limits of
the jurisdiction are those defined in the Industrial Arbitration
Act, and that if they have been exceeded the Supreme Court has,
and should have exercised, the power to maintain those limits
which was held to belong to it in Clancy's Case (1).
