A. rejection of confessions and looms largest in a consideration of the
subject. In New South Wales it has been formulated in the statutory provision that has been mentioned-s. 410 of the Crimes Act. Possibly that provision extends the common law rule for it includes untrue representations made to the accused person as well as threats and promises held out to him by persons in authority. By its third sub-section it removes any doubt created by the decisions in R. v. Drew (1) and R. v. Morton (2) that to tell a prisoner that what he said would be taken down and used for or against him at his trial amounted to an inducement. See however R. V. Baldry (3). Section 410 does not derogate from the common law rule, which remains applicable except in SO far as the section applies (Attorney-General (N.S.W.) v. Martin (4) ). The extreme applica- tions which were made at one time of the principle that confessions obtained by the use by persons in authority of hope or fear were inadmissible gave this head of inducement an importance which has tended to obscure other forms of inducement. It is perhaps doubt- ful whether, particularly in this country, a sufficiently wide opera- tion has been given to the basal principle that to be admissible a confession must be voluntary, a principle the application of which is flexible and is not limited by any category of inducements that may prevail over a man's will.
But, as the prisoner's counsel conceded, it is plain that the present case cannot be brought within the operation of the imperative rules of exclusion, common law and statutory. Certainly the fact that the prisoner was questioned by the police is not enough, even if he were in custody. The warning was given, there was no impor- tunity, no pressure, nothing to overbear the accused man's will.
The application for special leave is based upon the view that the learned judge possessed a discretion to exclude the statements and that he erroneously exercised this discretion in deciding to admit them. The view that a judge presiding at a criminal trial possesses a discretion to exclude evidence of confessional statements is of comparatively recent growth. To some extent the course of its development is traced by Lord Sumner in Ibrahim's Case (5). In part perhaps it may be a consequence of a failure to perceive how far the settled rule of the common law goes in excluding state- ments that are not the outcome of an accused person's free choice to speak. In part the development may be due to the fact that the
