 In some cases, the claims of the deceased will be in conflict with those of their families and/or the claims of potential recipients. The question arises of how to weigh the claims of the deceased. Some writers accept that the deceased can have posthumous interests, but believe them to be of little weight, particularly compared with the needs for organs of those with organ failure (Harris 2002, 2003). They may believe that people are not affected by their posthumous interests being set back or they may think the fear of retrieval is of little weight. In their view, any roughly consequentialist calculation would justify setting aside the objections of the deceased to organ retrieval. Other writers argue that if we accept posthumous interests and accept that people have strong claims over their bodies while alive, we have grounds to attribute rights to the living over their post-mortem bodies (T.M. Wilkinson 2011). Such a view needs to explain how posthumous rights are possible, since some writers in political and legal theory believe that rights could not protect posthumous interests for technical reasons to do with the nature of rights (Steiner 1994; Fabre 2008).
