The accused was charged with sexual assault and other offences.
At his third trial, the Crown sought to introduce his personal diary as part of its case-in-chief.
The trial judge excluded the diary, ruling its admission would violate the accused's Charter rights against self-incrimination by tactically compelling him to testify.
The Crown called no further evidence, resulting in an acquittal.
The Court of Appeal allowed the Crown's appeal, holding that the diary was created prior to state intervention and its admission did not create a legal compulsion to testify.
The Court also found no abuse of process in the Crown's decision to call no evidence.
