The appellant was convicted of offences arising from three separate gang home invasions.
The Crown alleged the appellant was involved in all three incidents, although membership in the gang rotated.
The trial judge instructed the jury that evidence admitted with respect to each incident was admissible in proving the guilt of the accused on the others.
The Supreme Court of Canada held that the trial judge erred.
While similar fact evidence of group activities is admissible to identify a gang responsible for a crime, it cannot be used to identify a particular member without an additional link connecting the individual to each crime.
The appeal was allowed and a new trial ordered.
