PRINCIPLES BACKING THE DISTINCTION BETWEEN INTERNATIONAL AND MUNICIPAL LAWS
Apart from theories, there are two principles that not only separate international and municipal laws from each other but also classify the states that pursue this distinction. In accordance with the first principle, the states where the international treaties automatically assume role in municipal sphere are ‘Self Executory States’ whereas the states which need international treaties to be translated into their municipal law first are ‘Non-self Executory States’.
THEORIES CLARIFYING THE RELATIONSHIP BETWEEN NATIONAL & INTERNATIONAL LAWS
It has always been a hot issue that which will prevail if International law and municipal law come into conflict with each other? The question is also related to the topic that international law is not a true law. Another side of the matter is that pursuance of international norms is essential to maintain international peace and security. Now which line a state should adopt? How a state is ought to treat international law in its municipal spheres? To answer these questions various theories have been procured.
