Such obligations derive, for example, in contemporary international law, from the outlawing of acts of aggression, and of genocide, as also from the principles and rules concerning the basic rights of the human person, including protection from slavery and racial discrimination.
Disse forpligtelser afledes f.eks. i moderne, international ret af forbuddet mod aggressive handlinger og folkedrab, men også af de principper og regler, der gælder den menneskelige persons grundlæggende rettigheder, heri indbefattet beskyttelse mod slaveri og racediskrimination.
