Open AccessThe 2005 UNESCO Universal Declaration of Bioethics and Human Rights (UDBHR) is specifically aimed at Africa and developing countries from other regions. The acceptance of this UNESCO instrument shows that global bioethics and human rights have become part of the bioethics discourse of today. It is clear that there is a certain affinity between human rights and bioethics, which makes such a link desirable. The value of this link lies in the fact that human rights facilitate a normative universal expansion of bioethical principles. The human rights framework provides bioethical principles with some authority and political influence, an instrument that can protect people in our broken context. Human rights practice and a reformed understanding of natural law both show that humanity can reach consensus on ethical principles such as those found in the UDBHR. Consensus on the theoretical foundation of human rights is not a prerequisite for the successful utilisation of these principles.
