What does the Doctrine of Necessity allow medical practitioners to do?

The Doctrine of Necessity permits medical practitioners to operate without consent in emergency situations when immediate action is required to prevent significant harm or injury to a patient. This legal principle is grounded in the understanding that in certain dire circumstances, obtaining consent may not be feasible, and the priority becomes the health and safety of the patient. For example, if a patient is unconscious and requires urgent surgery to save their life, the healthcare provider can proceed without explicit consent because the need for intervention takes precedence over consent protocols.

This doctrine is particularly relevant in emergency medical care where delays in treatment could lead to severe consequences. It protects healthcare professionals from legal liabilities associated with performing medical procedures in life-threatening scenarios without prior consent, as the rationale is that a reasonable person would consent to needed treatment in order to save their own life.
