R. v. B.D.
2011 ONCA 51
Ontario Court of Appeal — Gillese, Simmons and Blair JJ.A. | January 20, 2011
Background
This case began when a two-year-old girl named Wafu died at Cambridge Memorial Hospital in June 2001. When the man who brought her to the hospital was asked about his relationship to the child, he said he was her brother, not her father. But when the child's mother, B.D., arrived, she said the same man was her husband and the child's biological father.
The autopsy revealed that Wafu had very thin adrenal glands — a condition associated with inbreeding. Police became suspicious and obtained DNA warrants to test blood samples from B.D. and her alleged husband. The results were devastating: B.D. was the mother of the man she claimed was her husband, and he was indeed the father of the deceased child. The Crown's position was that B.D. had been living with and having children with her own son, Wafi. B.D. maintained that her "husband" was actually Prince Wafi R. Dz., a descendant of Nigerian/Ethiopian royalty, and that her real son Wafi had died tragically in a volcano in the Congo.
Issues
- Whether the DNA warrants were properly authorized under s. 487.05 of the Criminal Code
- Whether the trial judge erred in his jury instruction regarding reasonable doubt and conflicting evidence
- Whether documents seized from a Staples store should have been excluded
The DNA Evidence Challenge
B.D.'s lawyers argued that the DNA evidence should be excluded because the warrants didn't properly authorize comparing blood samples from two suspects against each other — only comparing each suspect's DNA to the deceased child's DNA. The Court of Appeal agreed this was a technical breach of s. 487.05 of the Criminal Code, but refused to exclude the evidence under s. 24(2) of the Charter. The court found the police acted in good faith, the breach was minor, and the DNA evidence was so reliable and crucial that excluding it would undermine the administration of justice.
The Jury Instruction Error
The trial judge told the jury they had to decide whether the co-accused was Wafi or Prince — essentially making it a credibility contest between Crown and defence witnesses. But the Court of Appeal found this was wrong. The judge should have instructed the jury using W.(D.) principles: even if they didn't believe the defence evidence, they still had to acquit if that evidence left them with reasonable doubt about the man's identity. However, the court applied the "curative proviso" — the evidence was so overwhelming that no properly instructed jury could have reached a different verdict.
Key Takeaway
Even serious legal errors can't save you when the evidence is overwhelming.
While technical defects in warrants and flawed jury instructions are serious legal errors, courts will sometimes overlook them when the evidence of guilt is so strong that no reasonable jury could have acquitted. The DNA evidence, combined with testimony from teachers, hospital staff, and elaborate identity fraud attempts, made this conviction inevitable despite the legal mistakes.
