So far I have been looking at the matter apart from sub-s. (5). It is now necessary to consider that sub-section, which creates a real difficulty. The first part of it, which says that an order under the section "may declare that a rule contravenes sub-s. (1)" seems at first sight to be superfluous in view of sub-ss. (2) and (3), which have already clearly given jurisdiction to make such an order. But sub-s. (5) goes on to say that, where a declaratory order is made, "the rule shall be deemed to be void from the date of the order." This latter part of sub-s. (5) does lend colour to an argument that, although the first four sub-sections, if they stood alone, would give a power of decision which is plainly judicial, sub-s. (5) shows that sub-s. (1) cannot be construed as laying down a legal criterion to be applied in arriving at a judicial decision. Apart from sub-s. (5), the position is simply that sub-s. (1) makes unlawful, and therefore void, any rule having any of the specified characteristics, and sub-ss. (2), (3) and (4) provide for a judicial determination as to whether any given rule "contravenes" sub-s. (1) and is therefore void. (One would think that a rule which fell within par. (a) would certainly, and that a rule which fell within par. (b) would probably, be void apart from any express statutory provision). But, when sub-s. (5) is added, it may be argued that the whole enactment assumes a radically different character. The first part of sub-s. (5) is not, it may be said, superfluous: the permissive "may" is introduced to indicate that it is all a matter of discretion, that no order need be made even if the Court is satisfied that a rule "contravenes" sub-s. (1). And the effect of the second part of sub-s. (5) is that, if, in the exercise of the discretion, an order is made, the order has no effect whatever as a judicial determination: it is merely a factum upon which sub-s. (5) operates in futurum, and in futurum only, to nullify the rule. We are thus back where we were under the old s. 140. The judicial trappings with which the function of the Court is clothed are merely a disguise, and what the Court is really being empowered to do differs in no substantial respect from the "disallowance" for which the old s. 140 provided.
