 Some states in the U.S. have implemented “first person” consent laws that mandate overriding families in cases where the deceased has ticked the “donate” box or its equivalent on a form. It is unclear how far such laws are upheld. In principle, it might be possible to get some data on the effect of overriding families on the organ supply, thus testing the practical argument in the previous paragraphs. Ethically, first person consent laws arguably do not respect the wishes of the deceased, at least in cases where the deceased donors who ticked the box did not fully grasp that their families’ wishes would be overridden.
