The appellant, Gary Hoffman, appealed his manslaughter conviction, raising three grounds: the trial judge's failure to give a W.(D.) direction regarding exculpatory evidence from a key witness (Peter Ojha), a misdirection on double hearsay contained in Ojha's K.G.B. statement, and a constitutional challenge to the Ontario Juries Act.
The Court of Appeal dismissed the constitutional challenge but found errors in the jury instructions regarding the W.(D.) direction and double hearsay.
The court held that a W.(D.) direction is required for exculpatory evidence from any witness, even if that witness also provides inculpatory evidence or if the exculpatory evidence relates to only one theory of culpability.
It also clarified that if a jury finds a K.G.B. statement to be based on double hearsay, they must disregard it entirely, rather than merely considering it for reliability.
Consequently, the manslaughter conviction was set aside, and a new trial was ordered.
