​KembaraXtra – Legal Terms – Proxy Decision


A proxy decision is a decision made on behalf of a person who lacks the legal capacity to consent to or refuse medical treatment. Such situations commonly arise where the patient is unconscious, mentally incapacitated, or otherwise unable to understand and communicate decisions concerning healthcare. In the case of children under sixteen who are not Gillick-competent, parents usually make proxy decisions regarding medical care. For adults, a person appointed under a lasting power of attorney may exercise decision-making authority if the patient loses capacity.


Proxy decisions are generally guided either by the patient’s best interests or by a substituted judgment approach that attempts to determine what the patient would have wanted in the circumstances. Courts and healthcare professionals must carefully balance respect for personal autonomy with the need to protect vulnerable individuals. Relevant considerations may include the patient’s previously expressed wishes, religious beliefs, welfare, and medical prognosis. Proxy decision-making therefore forms an important part of medical law and ethical healthcare practice, particularly in cases involving serious treatment choices or end-of-life care.
