The end of human life derives from the death which constitutes not only a biological but a legal fact too, as death implies very important legal consequences in the field of succession and human personality law. The differentiation between death and cerebral death became a source of confusion in law science. This confusion got worse by the fact that “classical” death is certified in a different way (law 344/1976) than cerebral death (law 2737/1999) whose provisions should be improved in a future legal reform. Greek legislation protects the end of human life: not only the human body which is considered a remains of the human personality but other expressions of this personality, such as honor and privacy. Provisions of penal and civil law concerning organs transplantation respect this attitude too: in fact, the Greek legislator has adopted the law system based on relatives’ consent: its aspects are critically analyzed in this paper.
