s 20 Certain aspects of causation of death
20.—(1) For the purposes of the laws of Singapore, the non‑application of extraordinary life‑sustaining treatment to, or the withdrawal of extraordinary life‑sustaining treatment from, a person suffering from a terminal illness does not constitute a cause of death where the non‑application or withdrawal was as a result of and in compliance with a directive validly made in accordance with this Act by the person. (2) This section does not relieve a medical practitioner from the consequences of a negligent decision as to whether or not a patient is suffering from a terminal illness.
