This is not a case where the prosecutors seek to prohibit the enforce-
ment of an order or a penalty but they ask that the further hearing
upon the summons be prohibited. Before a writ of prohibition
will be sent out of this Court it must clearly appear that there is a
want of jurisdiction in the tribunal to which it is addressed (R. v.
President of the Commonwealth Court of Conciliation and Arbitration ;
Ex parte Australian Agricultural Co. Ltd. (1). The terms of the Act,
particularly ss. 14, 16, 25, 34, 39 and 40, show that a case has not
been made out that the conciliation commissioner is about to, or
is even likely to exceed, his jurisdiction. It is not conceded that.
s. 13 is an absolute qualification of the powers of conciliation
commissioners under the Act. Section 34 is an important section
in practice in the Arbitration Court, because it by no means follows
that an application made to that Court is granted in the terms in
which it is sought. Under s. 39 a commissioner is not bound to act
in a formal manner, he is required to act according to equity and
good conscience and the substantial merits of the case without
regard to legal forms. Section 40 confers upon a commissioner
general powers with regard to disputes occurring within his juris-
diction. The court's jurisdiction is marked out by s. 25. In the
main the jurisdiction is defined. The matters enumerated in that
section are identical with those which are specified in s. 13.
Generally, the jurisdiction of the Arbitration Court and the juris-
diction of the commissioners are mutually exclusive. The Act
itself, by s. 16, provides its own means for determining the boundary
line between the jurisdiction of the court and the jurisdiction of
the commissioners. Section 13 read with s. 16, means that a
commissioner ' shall not be empowered to make an order or award
which in the opinion of the Full Court operates to alter the standard
hours of work in an industry." Although a question as to his
jurisdiction has been raised, before it is determined he is permitted
to make a tentative award if he so desires. Not only is he dealing
with collateral questions of law, but questions which go to the
jurisdiction, and in that very matter in which a question of
Jurisdiction has arisen he is given power, under s. 16 (4), to make
an order even though he has otherwise no jurisdiction. It is
