"The Tribunal consists of a Chairperson, who must be a
barrister or legal practitioner of not less than five years
standing, together with such number of persons as the
Governor considers necessary who possess expertise in
specified disciplines and such other persons as the Governor
considers necessary. Schedule 2 to that Act makes provision
with respect to the membership of the Tribunal and provides
that a member is appointed for a term of five years and is
eligible for reappointment. Whilst members of the Tribunal
do not have judicial tenure a limited form of tenure is
provided for by par6 of that Schedule. For the purposes of
the hearing and determination of an appeal (which includes an
application of the type before the respondent) the Tribunal
is to be constituted by any one of its members or by the
Chairperson and not more than four other members. Section 9
confers various powers on the Chairperson to determine the
constitution of the Tribunal from time to time.
Other relevant provisions contained in that Act are the
following:
'22 (1) For the purpose of an appeal, the Appeal Tribunal
may do all things necessary or convenient to be done for or
in connection with the hearing and determination of the
appeal.
...
23 (1) For the purpose of determining an appeal, the Appeal
Tribunal may exercise all the powers that are conferred by
the relevant legislation on the person who made the decision
that gave rise to the appeal.'
Counsel for the prosecutor submitted that the fact that the
powers conferred by s64 might be exercised by the Tribunal
constituted by a non legally qualified member indicated that
jurisdiction of the type proposed to be assumed by the
respondent was not intended to be conferred on the Tribunal.
He further submitted that the nature of the powers conferred
upon the Tribunal indicated an intention to exclude the
jurisdiction to examine the validity of subordinate
legislation. Counsel also referred to the power conferred on
the Tribunal by the Resource Management and Planning Appeal
Tribunal Act, s27 to refer a question of law arising in an
appeal before it to the Supreme Court for its decision. He
submitted that that provision provides the mechanism whereby
a question of the type proposed to be considered by the
respondent could be determined.
The powers conferred upon the Tribunal by s64 are markedly
different in nature from the primary jurisdiction conferred
upon it which is the determination of appeals against
planning decisions under s61. The relief which may be
granted under s64(3) is in the nature of injunctive relief,
in part mandatory. It is relief of a type normally granted
by superior courts. Formerly, by the Local Government Act
1962, s734(3), this Court had the power to enforce interim
orders by injunction. The effect of the prosecutor's
submission is that by conferring upon an administrative
tribunal a power of a type normally exercised by a court (at
least in part by taking away some of the statutory
jurisdiction of this Court and conferring it upon such a
tribunal) the power is to be exercised without regard to what
would be relevant considerations were the power being
exercised by a court. The Court ought not readily to accept
such a submission. Whilst the powers conferred by s64 have
been conferred upon an administrative tribunal they are not
powers of an administrative nature.
Whilst counsel for the prosecutor from time to time referred
to an absence of power on the part of the Tribunal to declare
the Regulations to be ultra vires, that is not what is at
issue. The nature of what is at issue was explained by
Latham CJ in South Australia v The Commonwealth (1942) 65 CLR
373 at 408 as follows:
'Common expressions, such as: "The courts have declared a
statute invalid," sometimes lead to misunderstanding. A
pretended law made in excess of power is not and never has
been a law at all. Anybody in the country is entitled to
disregard it. Naturally he will feel safer if he has a
decision of a court in his favour but such a decision is not
an element which produces invalidity in any law. The law is
not valid until a court pronounces against it and thereafter
invalid. If it is beyond power it is invalid ab initio.'
If the prosecutor's argument is right it would have the
result that the Tribunal would be unable to make an order
under s64, which otherwise it thought proper to make, because
of some regulation which in fact is invalid ab initio and
might be led into making an order under that section by force
of something contained in a regulation which is invalid ab
initio, in circumstances where in the absence of that
regulation it would not have considered it proper to make the
order.
In the course of any proceedings before it, the Tribunal may
be called upon to determine both questions of fact and law.
A variety of questions of law will arise before it. It may
be assumed that questions of the legal construction of
planning instruments will commonly arise before the Tribunal.
Counsel for the prosecutor did not suggest that such
questions of law were beyond the competence of the Tribunal
but submitted that the questions of the validity of
subordinate legislation fall into a special category of
matters of law which the Tribunal is not competent to
consider or determine. Counsel for the prosecutor did not
cite any clear authority in support of the proposition
advanced by him but referred to some authorities which he
submitted indicated that his submission ought to be
accepted."
