On 1 July 2020, the registration of organ and tissue donors in the Netherlands changed from an opt-in to an opt-out system. This means that everyone in the Netherlands will be registered as an organ and tissue donor unless they have registered a different choice in the donor register. The hope is that this new method for donor registration will lead to more donors. Only a small majority of members of the Senate and the House of Representatives in the Netherlands voted for the legislative amendment that enabled this new system to come into effect. In the Senate the amendment was defended on the grounds that it would do more justice to the autonomy of the deceased; the new law will, however, have to be defended from the principles of justice and solidarity by a government that feels responsibility towards those needing a donor organ.
