Mitra Javanmardi v. Her Majesty the Queen, et al. (38188)

Posted on: 2022-02-28


In June 2008, Roger Matern consulted the appellant, Mitra Javanmardi, a naturopath. Ms. Javanmardi administered an intraveous injection treatment. Mr. Matern died not long after the treatment. Ms. Javanmardi was charged, in connection with his death, with criminal negligence causing death and manslaughter.

The Court of Québec found on the basis of the evidence that the cause of Mr. Matern’s death was the injection administered by Ms. Javanmardi. But it acquitted her on both counts on the basis that, amoung other things, Ms. Javanmardi’s conduct had not involved a marked departure and her actions had not been objectively dangerous.

The Court of Appeal was of the opinion that errors of law had been made at trial. It found that all the essential elements of the offence of manslaughter had been established beyond a reasonable doubt and found Ms. Javanmardi guilty on that count. As for the count of criminal negligence, it found that a reassessment of the whole of the evidence was necessary and ordered a new trial for that purpose.
