limitations such as those suggested in argument, limitations discarded
by Parliament itself when repealing the earlier legislation ?
The only duty the Board has in this connection is to receive and consider any application for consent, to honestly deal with it, and to give or refuse its consent as it thinks the public interest in the performance of its mandate in sec. 13 requires. The main and overriding consideration is that mandate of sec. 13; if consistently with its own view of discharging that great function it thinks, for whatever reasons commend themselves to the Board, that the public welfare will be better served by granting or by refusing its consent, it should act accordingly. No Court can prescribe any narrower or stricter limits of duty. Indeed the very relaxation in favour of private interests which we pointed to indicates, when carefully considered, even apart from the express words of sec. 20, the absolute and complete discretion that Parliament has reposed in the Board. We are not prepared to say that the Board is not left at large to consider whether the Homebush abattoir is sufficient in existing circumstances for the needs of the population. If the Board thinks it is, and considers that no private slaughtering is necessary, that the attendant inspection would be risky and unnecessarily expensive, and that public danger would be thereby needlessly incurred, we must not be taken to denv the right of the Board in every case of application to act upon that view, and refuse consent until circum- stances, in its opinion, alter.
It is not necessary now to decide definitely SO much, but we say this in order to prevent it being supposed we are prepared to accede to the opposite contention.
The facts, in our opinion, do not indicate either directly or by inference any failure on the part of the Board to receive and con- sider, as it should, the various applications in question. (See per Lindley L.J. in In re Coalport China Case 1.)
Whatever view it might have entertained before Ex parte J. O Hutton Proprietary Ltd. 2 was determined by the Supreme Court, it must, in the absence of evidence to the contrary-and there is none -be presumed that the Board loyally conformed to that decision.
There are three cases which may be usefully taken as authorities
