Administrative law and constitutional law are closely related fields that deal with the relationship between the government and its citizens. While constitutional law is seen as more important, administrative law actually plays a crucial role in shaping how the government operates. Written constitutions don't do much to control the government's administrative side; they mainly set up the overall structure of governance. This means that administrative law has more flexibility and endurance than constitutions. By comparing different countries' administrative laws, we can see the limits of written constitutions and the importance of understanding how bureaucracy works in each nation.
