La Forest J held that there was no breach of the principles of fundamental justice because there are serious grounds on which objection can be raised to an absolute rule that testimonial immunity must always extend to evidence derived from compelled testimony: ‘While allowing the Crown to use such evidence in criminal proceedings may in a formal sense be equivalent to permitting direct reliance on the compelled testimony itself, there is an important difference between the type of prejudice that will be suffered in the two cases. It is only when the testimony itself has to be relied on that the accused can be said to have been forced to actually create self-incriminatory evidence in his or her own trial. The compelled testimony is evidence that simply would not have existed independently of the exercise of the power to compel it; it is in this sense evidence that could have been obtained only from the accused.
By contrast, evidence derived from compelled testimony is, by definition, evidence that existed independently of the compelled testimony. This follows logically from the fact that it was evidence which was found, identified or understood as a result of the ‘clues’ provided by the compelled testimony. Although such evidence may have gone undetected or unappreciated in the absence of the compelled clues, going undetected or unappreciated is not the same thing as non-existence. The mere fact that the derivative evidence existed independently of the compelled testimony means that it could have been found by some other means, however low the probability of such discovery may have been.’
The fact that the derivative evidence exists independently of the compelled testimony also means that its quality as evidence and its relevance to the issues in the trial do not depend on its past connection with the compelled testimony.
