The accused appealed a sexual assault conviction on the basis that his court-appointed interpreter, when called as a defence witness, failed to provide full and contemporaneous interpretation of his own testimony and part of an exchange with the trial judge.
The Court held that s. 14 of the Charter protects an accused's right to interpretation that is continuous, precise, impartial, competent and contemporaneous whenever the case is being advanced.
The Court rejected any requirement to prove actual prejudice at the breach stage, found no valid personal waiver, and held that the Criminal Code curative provisos do not apply to an infringement of the constitutional right to interpreter assistance.
Because the breach occurred during material trial evidence on identification, the conviction was quashed and a new trial ordered.
