What has been said about the circumstances in which the statements came to be made represents in a condensed form the material on which the learned trial judge had to decide whether they should be admitted in evidence. The arguments put to him against the admission of the documents took many forms, as did the submissions made on this application. It was contended that each of the applicants when he appeared at the Coroner's inquest was an "accused person" within the meaning of s. 26 of the Coroners Ordinance which extends to such a person the right given to a "person charged with an offence" by s. 58 (1) of the Evidence and Discovery Ordinance. Section 58 (1) (i) of this last mentioned Ordinance provides (inter alia) that every person charged with an offence shall be a competent witness for the defence but "shall not be called as a witness except upon his own application". For this reason, it was said, the applicants should not have been called as witnesses before Mr. Carey since none of them had applied to give evidence and the statements they had made should therefore not be admitted at the trial. This submission was rejected by his Honour who rightly took the view that at the time when each of the applicants made his statement to Mr. Carey he was not "an accused person" or "a person charged with an offence". Before this Court, counsel for the applicants placed no reliance on this point. He contended, however, that for other reasons the statements were inadmissible. The applicants had not been summoned before the Coroner by subpoena but had been unlawfully arrested and held in custody and in such circumstances their statements to Mr. Carey should not have been admitted. Furthermore, Mr. Carey in addition to being a Coroner was also the officer in charge of the native constables who had been sent out to find persons who could give an account of the killings. The functions of Coroner and Police Officer were not compatible and the inquest should therefore be regarded as a police investigation of a kind which required that statements made by the applicants in the course of it should be rejected. Our attention was also drawn to the fact that the "affirmation" administered to the applicants by Mr. Carey was not in the form set out in the schedule to the Oaths Ordinance. Section 22 (1) of that Ordinance provides, however, that if in any civil or criminal proceeding it appears to the court or a justice or person authorized to administer an oath that a witness is incapable of comprehending the nature of an oath or of understanding the meaning of the solemn declaration in the schedule, it shall be the duty of such court, justice or other person authorized to administer the oath, if satisfied that such person if called as a witness understands that he will be liable to punishment if his evidence is untruthful, to declare in what manner the evidence of such person shall be taken and the evidence so taken shall be valid as if an oath had been administered in the ordinary manner. The form of "affirmation" administered by Mr. Carey was one which is in common use in the Territory when evidence is taken from native witnesses and the fact that Mr. Carey administered it sufficiently shows that he declared the manner in which the evidence was to be taken. But submissions based wholly upon suggested illegalities or informalities in bringing the applicants before Mr. Carey and in the taking of their statements fail to take account of the real issues which the learned trial judge was required to decide on the voir dire. Those issues were whether the statements were voluntary or, in the alternative, whether, being voluntary, they had been obtained in the course of the investigation by the use of unfair or improper methods so as to make it right as a matter of discretion to reject them. The fact that relevant evidence has been unlawfully or irregularly obtained does not, in itself, afford a reason for refusing to admit it in evidence: Reg. v. Leatham [1] ; R. v. Reed [2] ; Lloyd v. Mostyn [3] ; Calcraft v. Guest [4] ; Bell v. David Jones Ltd. [5] ; Kuruma v. The Queen [6] , although if it has been so obtained that is a matter to be considered, along with all other relevant circumstances, in determining whether the evidence should be admitted against an accused person in a criminal trial. That the applicants were kept under restraint and were brought before Mr. Carey in custody were relevant circumstances in determining the issues which the learned judge had to consider, as were the statements made to the applicants by Constable Gaigo before he brought them into camp and the statements, including the "affirmation", made by Mr. Carey when each of the applicants appeared before him at the inquest. And all these circumstances were rightly taken into consideration by his Honour.
