 Is it right to use the bodies of the deceased without either their consent or knowing that they had wanted the use? The question is an important and difficult one. It is very important to note, however, that this question is raised by virtually all existing organ procurement systems To restate: all systems allow organs to be taken without the deceased’s consent. It follows that the simple inertia argument for shifting defaults is flawed. There is no default of non-retrieval in the absence of the deceased’s consent. Other arguments for variations of opting out turn on the empirical question of effects on retrieval. Since many different factors affect retrieval rates, it is often hard to be confident about the difference that changes to consent would make.
