In the third place, the exposition lays it down that in the exercise of the discretion the possibility or probability that some "impropriety" might lead to the making of an untrue admission is to be disregarded as an irrelevant consideration. This is not in our opinion correct. Surely, if the judge thought that the "impropriety" was calculated to cause an untrue admission to be made, that would be a very strong reason for exercising his discretion against admitting the statement in question. If, on the other hand, he thought that it was not likely to result in an untrue admission being made, that would be a good reason, though not a conclusive reason, for allowing the evidence to be given. Although the better opinion seems to be that the rule which excludes non-voluntary statements is based on broad grounds of policy, many judges have (as already stated) considered that the possibility of an untrue confession being made was the justification, or one justification, for the rule: see, e.g., R. v. Court [1] , quoted by Dixon J. in Sinclair v. The King [2] . In R. v. Baldry [3] Lord Campbell C.J. had, in considering at the trial whether a certain confession by a person in custody ought to be admitted, taken into account among other matters "that it could have no tendency to induce him to say anything untrue", and Parke B. said that he considered that the reasons given by the Lord Chief Justice for admitting the evidence were "satisfactory". See also per Starke J. in Sinclair v. The King [4] , and cf. per Dixon J. [5] . In Victoria, where s. 141 of the Evidence Act 1928 is in force, it affords, we think, a strong additional reason for regarding as relevant, though not necessarily decisive, the question whether any "impropriety" was such as to be likely to result in the making of an untrue admission. If this were not so, the position would, as is pointed out by Gavan Duffy J. in his report to the Full Court, be absurd. A confession obtained by a serious threat or promise might be admitted of necessity under s. 141, while a confession following upon some far less serious impropriety could be rejected in the exercise of discretion.
