 It is now well-established in many jurisdictions that competent patients are entitled to make their own decisions about life-sustaining medical treatment. That is why they can refuse such treatment even when doing so is tantamount to deciding to end their life. It is plausible to think that the fundamental basis of the right to decide about life-sustaining treatment – respect for a person’s autonomy and her assessment of what will best serve her well-being – has direct relevance to the legalization of voluntary euthanasia (see, e.g., Dworkin in Frey et al., 1998; Young 2007, 2017; Sumner 2011). In consequence, extending the right of self-determination to cover cases of voluntary euthanasia does not require a dramatic shift in legal policy. Nor do any novel legal values or principles need to be invoked. Indeed, the fact that suicide and attempted suicide are no longer criminal offences in many jurisdictions indicates that the central importance of individual self-determination in a closely analogous context has been accepted. The fact that voluntary euthanasia and physician-assisted suicide have not been more widely decriminalized is perhaps best explained along a similar line to the one that has frequently been offered for excluding the consent of the victim as a justification for an act of killing, namely the difficulties thought to exist in establishing the genuineness of the consent. But, the establishment of suitable procedures for giving consent to voluntary euthanasia and physician-assisted suicide is surely no harder than establishing procedures for competently refusing burdensome or otherwise unwanted medical treatment. The latter has already been accomplished in many jurisdictions, so the former should be achievable as well.
