The appellant was charged with sexual assault.
During the investigation, a police officer made a tape recording of an initial interview with the complainant but subsequently lost it.
The trial judge entered a stay of proceedings due to the Crown's failure to disclose the tape.
The Court of Appeal set aside the stay and ordered a new trial.
The Supreme Court of Canada dismissed the appeal, holding that where the Crown loses evidence, it must provide a satisfactory explanation.
If the explanation satisfies the court that the evidence was not destroyed or lost due to unacceptable negligence, the disclosure obligation is discharged, provided there is no abuse of process or actual prejudice to the accused's right to make full answer and defence.
