Abstract

The Canadian law governing informed consent was significantly influenced by the decision of its Supreme Court in Reibl v. Hughes, a case that involved a physician’s failure to warn the patient about the risk of stroke after carotid endarterectomy. Even though most Canadian plaintiffs after Reibl have continued to lose informed consent cases, it is likely that the judgement in this case has significantly influenced the manner in which physicians now approach the discussion of risk while obtaining consent not only in Canada but also in several other jurisdictions.The development of informed consent law in the United States similarly became one of the drivers for change in physicians’ practices of information disclosure to their patients. The effect of Reibl on clinical practice is an outstanding example of the law’s positive influence on medical practice, especially in protecting patient autonomy during collaborative medical decision-making.
