Legal considerations for the definition of death in the 2023 Canadian Brain-Based Definition of Death Clinical Practice Guideline.

Purpose: The new 2023 Canadian Brain-Based Definition of Death Clinical Practice Guideline provides a new definition of death as well as clear procedures for the determination of death (i.e., when that definition is met). Since physicians must practice in accordance with existing laws, this legal analysis describes the existing legal definitions of death in Canada and considers whether the new Guideline is consistent with those definitions. It also considers how religious freedom and equality in the Canadian Charter of Rights and Freedoms might apply to the diagnosis of brain death.

Method: We performed a legal analysis in accordance with standard procedures of legal research and analysis-including reviews of statutory law, case law, and secondary legal literature. The draft paper was discussed by the Legal-Ethical Working Subgroup and presented to the larger Guideline project team for comment.

Results And Conclusion: There are some differences between the wording of the new Guideline and existing legal definitions. To reduce confusion, these should be addressed through revising the legal definitions. In addition, future challenges to brain death based on the Charter of Rights and Freedoms can be anticipated. Facilities should consider and adopt policies that identify what types of accommodation of religious objection and what limits to accommodation are reasonable and well-justified.
