International treaties are binding on States and international organisations, which are the real subjects of international law. But they can, also have effects on individuals and firms.
There are several answers to the question whether international law is a legal system in its own right and, if so, how it should be incorporated into national law to produce its effects.
Certain Member States have adopted the unitary theory, whereby international law is a direct part of the domestic legal system; others have preferred the dualist theory, whereby international law and domestic law are two separate and independent legal systems. In the latter case, international law has to be incorporated into the domestic legal system by statute.
You can find information on this by clicking on the flags of the Member States.The main international organisations working on private international law are the Council of Europe and the Hague Conference on Private International Law.
