International law (or “ius gentium” law of peoples / peoples) is that set of rules and principles that regulate relations between states and govern commercial, social and economic aspects of the life of the international community.
International law arises from the collaboration between the adhering States and is placed above each of them by spontaneous adhesion.
The sources of international law are customs and treaties, traditionally accepted on the basis of the “pacta sunt servanda” principle.
Subjects of international law are states and international organizations.
Private international law is a fundamental part of Italian law, governing jurisdiction and applicable law in all those cases, which occur in Italy or which concern the Italian state, and which present elements of extraneousness to the Italian legal system.
