The appellant was convicted of robbery, disguise with intent, and possession of an imitation firearm, and sentenced to 30 months' imprisonment.
On appeal, he argued the trial judge erred in allowing the Crown to cross-examine his mother, an alibi witness, on a prior false police report, and in failing to properly instruct the jury on the use of that evidence.
The Court of Appeal found the cross-examination was generally permissible but the jury instructions were inadequate.
However, the Court applied the curative proviso due to the overwhelming evidence of guilt.
The sentence appeal was allowed, and the sentence was reduced to two years less a day to reflect the youthful offender's excellent prospects for rehabilitation.
