This is a ruling on the admissibility of defence expert opinion evidence in a criminal trial involving two sisters charged with killing their mother.
The defence sought to call Dr. Danièle Bélanger, an expert in Vietnamese society, gender, family, and migration, to provide cultural context evidence.
The Crown opposed the admission of this evidence.
The trial judge conducted a voir dire and ruled that the expert evidence was admissible, finding that it met all threshold requirements under the Mohan framework and that the probative value outweighed any prejudicial effects.
The evidence was found to be logically relevant to issues of credibility, motive, intent, and self-defence, and necessary to assist the jury in understanding the accused's state of mind and the cultural context in which they operated.
