Sally is 22 years old and has a 6 year history of anorexia nervosa. In recent weeks, her condition has deteriorated to the point where her treating Medical Officer has prescribed the administration of artificial nutrition (in the form of PEG feeds). However, Sally is refusing to consent to both the insertion of a PEG tube and to artificial feeding. Does Sally have a legal right to refuse these procedures?
