Family Consent and Organ Donation

This paper asks whether investigation into the ontology of the extended family can help us to think about and resolve questions concerning the nature of the family's decision-making authority where organ donation is concerned. Here, "extended family" refers not to the multigenerational family all living at the same time, but to the family extended past its living boundaries to include the dead and the not yet living. How do non-existent members of the family figure into its ontology? Does an answer to this question help to resolve questions about the distribution of authority within the extended family?
