Abstract:
In each legal system, there is hierarchy between its rules; this
means some rules precede other rules in the application. However,
there is no general system of hierarchy of norms of international
law. This is because there is no formal constitution, there is no
centrallegislator, and sources of international law are organized on
horizontal manner. This study examines the relationship between
the rules of public international law in order to reach a kind of
hierarchy or arrangement between them.There is no doubt that the
presence of hierarchy of norms of international law is important
and indispensable. It reflects the existences of some international
rules are more important than others. It is necessary to anticipate
the legal rule which can be applied. This is important to States and
international organizations to know which rules can be applied
regarding to their actions. It is also necessary for the international
judge to know which rules have the priority in application regarding
to the international disputes.
