Constitutional law is an area of law that shows how the institutions of a country are organised, and the basic rights rights of citizens. In most countries, such as the United States, this is found in a written text called a constitution. Some countries use a lot of different texts and unwritten rules instead, such as the United Kingdom.
State structure[change | change source]
Constitutional law explains how different institutions relate to each other. For example, the relationship between the legislature, executive, and judiciary. In a federal country, constitutional law explains what the powers of the central government and state governments are.
