One of the most controversial aspects in uncontrolled donation of organs after circulatory death is the initiation of preservation measures before death. I argue that in so-called opting-out systems only under very stringent conditions we might presume consent to the instauration of those measures. Given its current legal framework, I claim that this is not the case of Spain, a well-known country in which consent is presumed—albeit only formally—and where uDCD is currently practiced.

This article explores the meaning and moral significance of presumed consent with particular reference to an opt-out policy for postmortem organ donation. It does so under two general categories: circumstances where we believe consent to have been given and those where we have no reason to believe that it has either been given or been refused. In the context of an opt-out policy, the first category would relate to the idea of tacit consent. It is argued both that substituting the (...) term ‘presumed consent’ would be misleading and that it is unlikely that the conditions for tacit consent would be met in practice. Regarding the second category, where the claim would be one regarding counterfactual consent, two main points are made: that claims about consent are unwarranted, and also that they are unnecessary to moral argument, given that the moral work is done by reasons other than any supposedly provided by a presumption of consent.
