“That may come at the trial. But this is not a trial and it is not necessary to make findings of fact which will be inappropriate on this application. All it seems to me that the respondents have to do is to adduce sufficient evidence to establish prima facie that there is an arguable case that the permit is one on which they can rely. A permit that they can rely upon is simply one that is regular on its face and which has been issued by the proper authorities with conditions that have been complied with in the opinion of the decision-maker.”
“An order, even if not made in good faith, is still an act capable of legal consequences. It bears no brand of invalidity upon its forehead. Unless the necessary proceedings are taken at law to establish the cause of invalidity and to get it quashed or otherwise upset, it will remain as effective for its ostensible purpose as the most impeccable of orders.”
