ADVANTAGE AND IMPORTANCE OF THE INTERNATIONAL CONSTITUTION
International constitutional is the study of constitutions in general, and combines aspects of constitutional law, public international law and legal theory. It adds international and transnational treaties to constitutional law. In federal states, sub-national constitutions can also be identified. In this multi-level approach to constitutional law there are various relationships between constitutions (network of constitution law).
A constitution is a set of fundamental principles or established precedents according to which a state or other organization is governed.[1] These rules together make up, i.e. constitute, what the entity is. When these principles are written down into a single document or set of legal documents, those documents may be said to embody a written constitution; if they are written down in a single comprehensive document, it is said to embody a codified constitution. Some constitutions (such as the constitution of the United Kingdom) are unmodified, but written in numerous fundamental Acts of a legislature, court cases or treaties.
