The accused was charged with possession of LSD for the purpose of trafficking after police found a bag of LSD with his fingerprints under a sofa in his shared residence.
A co-tenant testified that the accused was a drug dealer and owned the drugs.
The trial judge convicted the accused, but the Court of Appeal ordered a new trial.
The Supreme Court of Canada allowed the Crown's appeal and restored the conviction, holding that the trial judge was entitled to infer possession from the fingerprint evidence combined with the co-tenant's testimony, which was admissible as it was relevant to the issue of possession and not merely character evidence.
