Charter of the United Nations and Statute of the International Court of Justice.
Signed on 26 June 1945, the Charter of the United Nations is the Organization’s constitutive instrument, setting out the rights and obligations of Member States, and establishing its principal organs and procedures. An international treaty, the Charter codifies basic tenets of international relations — from the sovereign equality of States to prohibition of the use of force in any manner inconsistent with the purposes of the United Nations.
