Criminal law - Evidence - Crown's obligation to make disclosure to defence - Witness favourable to accused interviewed by police - Crown not calling witness and refusing to produce statements obtained - Whether Crown obliged to disclose statements.

The accused, a lawyer, was charged with breach of trust, theft and fraud. A former secretary of his was a Crown witness at the preliminary inquiry, where she gave evidence apparently favourable to the defence. After the preliminary inquiry but prior to trial, the witness was interviewed by an RCMP officer and a tape-recorded statement was taken.

Later, during the course of the trial, the witness was again interviewed by a police officer and a written statement taken. Defence counsel was informed of the existence but not of the content of the statements. His requests for disclosure were refused. During the trial defence counsel learned conclusively that the witness would not be called by the Crown and sought an order that the witness be called or that the Crown disclose the contents of the statements to the defence. The trial judge dismissed the application. The trial proceeded and the accused was convicted of breach of trust and fraud. Conditional stays were entered with respect to the theft counts. The Court of Appeal affirmed the convictions without giving reasons.

Held: The appeal should be allowed and a new trial ordered.

The Crown has a legal duty to disclose all relevant information to the defence. The fruits of the investigation which are in its possession are not the property of the Crown for use in securing a conviction but the property of the public to be used to ensure that justice is done. The obligation to disclose is subject to a discretion with respect to the withholding of information and to the timing and manner of disclosure. Crown counsel has a duty to respect the rules of privilege and to protect the identity of informers. A discretion must also be exercised with respect to the relevance of information. The Crown's discretion is reviewable by the trial judge, who should be guided by the general principle that information should not be withheld if there is a reasonable possibility that this will impair the right of the accused to make full answer and defence. The absolute withholding of information which is relevant to the defence can only be justified on the basis of the existence of a legal privilege which excludes the information from disclosure. This privilege is reviewable, however, on the ground that it is not a reasonable limit on the right to make full answer and defence in a particular case.

Counsel for the accused must bring to the trial judge's attention at the earliest opportunity any failure of the Crown to comply with its duty to disclose of which counsel becomes aware. This will enable the trial judge to remedy any prejudice to the accused if possible and thus avoid a new trial.

Initial disclosure should occur before the accused is called upon to elect the mode of trial or plead. Subject to the Crown's discretion, all relevant information must be disclosed, both that which the Crown intends to introduce into evidence and that which it does not, and whether the evidence is inculpatory or exculpatory. All statements obtained from persons who have provided relevant information to the authorities should be produced, even if they are not proposed as Crown witnesses. Where statements are not in existence, other information such as notes should be produced. If there are no notes, all information in the prosecution's possession relating to any relevant evidence the person could give should be supplied.

Crown counsel was not justified in refusing disclosure here on the ground that the witness was not worthy of credit: whether the witness is credible is for the trial judge to determine after hearing the evidence. The trial judge ought to have examined the statements. Since the information withheld might have affected the outcome of the trial, the failure to disclose impaired the right to make full answer and defence. There should be a new trial at which the statements are produced.
