Most international courts (like the International Court of Justice (ICJ) or International Criminal Court (ICC)) are created by treaties. When a country signs and ratifies that treaty, it agrees to be bound by the court’s jurisdiction in certain matters.
Example: The Rome Statute (1998) established the ICC. Only countries that ratified it accept the ICC’s authority.
I have a problem with the "international court of law" concept. Who the hell elected "international organizations"?
