39 The present question must proceed on the assumption that a prosecution has been instigated. The question is whether Baker instigated that prosecution. In dealing with the present question, it seems to me that the judge may have been diverted by his earlier conclusion that there was no prosecution. However, assuming for present purposes that what befell Mutton was a prosecution, it is necessary to determine whether he has alleged sufficient material facts to make good his claim that Baker instigated the prosecution. In Davis v Gell,[53] Isaacs ACJ said that the law 'looks beyond theory and regards the person in fact instrumental in prosecuting the accused as the real prosecutor.'[54] Similarly, in Commonwealth Life Assurance Society Ltd v Brain,[55] Dixon J said that the fact that a prosecutor had an independent discretion was not decisive. He said '(b)ut, if the discretion is misled by false information, or is otherwise practised upon in order to procure the laying of the charge, those who thus brought about the prosecution are responsible'.[56] Similarly, in Martin v Watson,[57] Lord Keith said '(w)here the circumstances are such that the facts relating to the alleged offence can be within the knowledge only of the complainant, as was the position here, then it becomes virtually impossible for the police officer to exercise any independent discretion or judgment, and if a prosecution is instituted by the police officer the proper view of the matter is that the prosecution has been procured by the complainant'.[58]
