The national State has the right to protect the individual who has suffered injury in consequence of a breach of international law by another State.Diplomatic protection is primarily exercised by the State towards its citizens and exceptionally non-citizens. Diplomatic protection has changed in recent years. The development of human rights has advanced the position of the individual in international law, thing that has led some scholars to argue that diplomatic protection is obsolete. Their arguments represent the exaggeration of the present state of international protection of human rights. Individuals may have rights under international law as human beings, but they don’t have remedies under international law. The only way to protect their rights is through the intervention of their national State. Diplomatic protection cannot be abandoned until the individual acquires procedural rights under international law. The State cannot grant diplomatic protection unless the prerequisites are met: the rule of nationality, exhaustion of local remedies, breach of international law, “clean hands” doctrine.
