The pyramid diagram of this Introduction to Law illustrates the relationships between different levels in the legal system. At the top of the pyramid is the Constitution, which, as the highest law of the country, has the highest legal effect. Below it is the law, which is a specific refinement and supplement to the constitution. Going further down is the resolution legislation, which is a legal document formulated by the legislative body. Then there are laws and regulations issued by administrative agencies. Finally, there is a resolution, a decision made by a specific organization or individual. This hierarchical structure ensures the orderliness and stability of the legal system.
