Abstract

Honesty, loyalty and reasonableness together refer to the principle of good faith in contemporary private law. The principle of good faith historically emerged as a natural law principle deriving from Roman law of nations, the universal set of rules applicable for all mankind. However, it also has immense historical effects on the early modern theories of international law. Being based on natural law and morality, good faith is well-equipped to be a fundamental standard of behavior in contemporary international law concerns. Good faith manifests itself as pacta sunt servanda as the basis of international treaty law. As a principle referring to honesty, loyalty and reasonableness, it guarantees the prohibition of the abuse of power and provides equitable solutions in legal relationships between sovereigns and private actors. Accordingly this article examines the application of the classical Roman principle of good faith in international law from a transhistorical perspective to clarify its contemporary applications, taking refugee law as an example. It concerns itself with the fundamental elements of good faith, the historical emergence of the principle, its relationship with early modern international legal theories and its contemporary significance in refugee law.
