(1) The Tribunal has,
when dealing with a matter in the exercise of its review jurisdiction,
functions and discretions corresponding to those exercisable by the
decision-maker in making the reviewable decision.
(2)
Subsection (1) does not limit the powers given by this Act or the
enabling Act to the Tribunal.
(3) The Tribunal
may —
(a)
affirm the decision that is being reviewed;
(b) vary
the decision that is being reviewed; or
(c) set
aside the decision that is being reviewed and —
(i)
substitute its own decision; or
(ii)
send the matter back to the decision-maker for
reconsideration in accordance with any directions or recommendations that the
Tribunal considers appropriate,
and, in any case, may
make any order the Tribunal considers appropriate.
(4) The fact that a
decision is made on reconsideration as required under
subsection (3)(c)(ii), does not prevent the decision from being open to
review by the Tribunal.
(5) The
decision-maker’s decision as affirmed or varied by the Tribunal or a
decision that the Tribunal substitutes for the decision-maker’s
decision —
(a) is
to be regarded as, and given effect as, a decision of the decision-maker; and
(b)
unless the enabling Act states otherwise or the Tribunal orders otherwise, is
to be regarded as having effect, or having had effect, from the time when the
decision reviewed would have, or would have had, effect.
(6) Without limiting
subsection (5)(a), the decision-maker has power to do anything necessary
to implement the Tribunal’s decision.
(7) Despite
subsection (5)(a), the decision as affirmed, varied, or substituted is
not again open to review by the Tribunal as a decision of the decision-maker.
(8)
Subsection (5)(a) does not affect an appeal under Part 5 against the
Tribunal’s decision.
(9) To avoid doubt it
is declared that this section and section 27 do not extend to requiring or
enabling the Tribunal to deal with a matter that is different in essence from
the matter that was before the decision–maker.
