par. 3 is committed by persons subject to military law who join in,
or being present do not use their utmost endeavours to suppress, any
mutiny or sedition in any of His Majesty's military, naval, or air
forces (including any Dominion force). Offences under s. 7 are
tried by court-martial and on conviction the accused is liable to
suffer death or such less punishment as is in the Act mentioned.
The section as modified by Australian Mihtary Regulations, reg.
202 (c) contains a proviso that a member of the Military Forces
of the Commonwealth of Australia shall not be sentenced to death
under the section, except for the offence of joining in such a mutiny
as is mentioned in par. 3. It is admitted that the other confinees
referred to in the particulars are all' men who, at the date of the
alleged offence, had, like the prosecutor, been discharged from the
defence force, and it was submitted that collective insubordination
by such confinees could not be mutiny in His Majesty's military
forces because none of the confinees were members of the defence
force. Section 158 (2) does not provide that a confinee, notwith-
standing his discharge, is to be deemed to be for any purpose a mem-
ber of the defence force. All that it does is to provide that the
Army Act is to apply to him during the term of his sentence notwith-
standing his discharge, and that he can be punished in accordance
with the Act as if he continued to be subject to military law. Neither
the prosecutor nor the other confinees were, therefore, at the material
date, members of His Majesty's forces, actually or notionally.
Civilians subject to military law can be punished in accordance with
the Army Act for offences, of which there are many, which can be
committed by any person subject to military law, but collective
insubordination by a number of civilians could not be joining in a
mutiny in His Majesty's forces. At the adjournment of the general
court-martial, therefore, the trial of the prosecutor had reached the
stage at which it was clear on my view of the law that he was being
tried for an offence to which he was not made subject by s. 158 (2).
The court-martial intends to accept as correct and binding upon it
under reg. 575 (10) a ruling of the Judge Advocate-General that the
prosecutor and the other confines are in His Majesty's forces because
they are in an establishment which is part of the Australian Military
Forces. But I cannot agree with this ruling. If it were correct,
civilians who had never been in the Army but who were sentenced to
detention in a military camp would become members of His Majesty's
forces. A writ of prohibition may be applied for as soon as the
absolute absence of jurisdiction is apparent on the record of the
proceedings of the inferior tribunal : Halsbury's Laws of England
