This article, prompted by an extended essay published in theJournal of Medical Ethicsby Charles Foster, and the current controversy surrounding the case of Vincent Lambert, analyses the legal and ethical arguments in relation to the withdrawal of life-sustaining treatment from patients with prolonged disorders of consciousness. The article analyses the legal framework through the prism of domestic law, case-law of the European Court of Human Rights and the Convention on the Rights of Persons with Disabilities, and examines the challenge to (...) the ethical consensus made by Foster. It concludes that the right approach remains a version of the approach that has prevailed for the last 25 years since the decision inAiredale NHS Trust v Bland[1993] AC 789, refined to reflect that that there is now, and rightly, a much more limited place for judgments made about the ‘burden’ of treatment or the quality of life enjoyed by the person made on the basis of assumptions about that person as a category as opposed to investigation of that person as an individual human being.

In English law there is a strong (though rebuttable) presumption that life should be maintained. This article contends that this presumption means that it is always unlawful to withdraw life-sustaining treatment from patients in permanent vegetative state (PVS) and minimally conscious state (MCS), and that the reasons for this being the correct legal analysis mean also that such withdrawal will always be ethically unacceptable. There are two reasons for this conclusion. First, the medical uncertainties inherent in the definition and diagnosis (...) of PVS/MCS are such that, as a matter of medical fact, it can never be established, with the degree of certainty necessary to rebut the presumption, that it is not in the patient’s best interest to remain alive. And second (and more controversially and repercussively), that even if permanent unconsciousness can be unequivocally demonstrated, the presumption is not rebutted. This is because there is plainly more to human existence than consciousness (or consciousness the markers of which can ever be demonstrated by medical investigations). It can never be said that the identity of the patient whose best interests are at stake evaporates (so eliminating the legal or ethical subject) when that person ceases to be conscious. Nor can it be said that the best interests of an unconscious person do not mandate continued biological existence. We simply cannot know. That uncertainty is legally conclusive, and (subject to resource allocation questions and views about the relevance of family wishes and the previously expressed wishes of the patient) should be ethically conclusive.
