The Crown sought to admit expert evidence from Dr. Neil Lazar in a criminal trial for manslaughter and criminal negligence causing death against Joanna Flynn, a registered nurse.
The proposed evidence concerned medical ethics and accepted practices in ICUs regarding end-of-life decision-making, including determination of death, discontinuing life support, and obtaining informed consent from substitute decision-makers.
The defence opposed, arguing irrelevance, lack of qualification, and prejudicial effect.
The court applied the two-stage Mohan/White Burgess test for expert evidence admissibility.
It found Dr. Lazar qualified as an expert in medical ethics and ICU decision-making.
The court ruled that evidence regarding the 24-hour wait period before terminating life support and the process of obtaining informed consent from a substitute decision-maker was admissible, as it was relevant and necessary for the jury.
However, evidence related to the technical declaration of "brain death" and the specific GBGH Discontinuation of Life Support policy was deemed irrelevant or outside Dr. Lazar's expertise for interpretation and thus inadmissible.
