Uncovering all the facts requires more than meetings with your own client and the client’s witnesses. Complete disclosure is paramount, although the issue of what can or should be disclosed in any given case is by no means uncontroversial.
The right of the accused to full disclosure by the Crown is an adjunct of the right to make full answer and defence. One important source of information, of course, is that information in the possession of the Crown. The term “in the possession of the Crown” is now understood to include all information in the possession or knowledge of the police. In 1991, Justice Sopinka, writing for a unanimous court in R v. Stinchcombe1, reviewed the general principles governing the duty of the Crown to make disclosure to the defence, especially in the context of indictable offences. He concluded that the Crown’s general obligation is to disclose all relevant information, even if the Crown does not propose to adduce it at trial. His Lordship also noted, however, that the Crown’s obligation is not absolute. It is subject to the Crown’s discretion, a discretion extending both to the withholding of information and to the timing of disclosure.
