Constitutional law is a body of law that defines the role, powers, and composition of various entities within a state, namely the executive, parliament or legislature and the judiciary; as well as the fundamental rights of citizens and, in federal countries such as the United States and Canada, the relationship between the central government and state, provincial or territorial governments.

Not all nation-states have codified constitutions, although all such states have a jus commune, or law of the land, which may include a number of obligatory and consensual rules. These may consist of conventions, customary law, statutory law, judge-made law, or international rules and norms.

Constitutional law is basically the study of the fundamental principles by which the government exercises its authority. In some instances, these principles give specific powers to the government, such as taxes and spending power for the welfare of the population. Other times, constitutional principles serve to impose limits on what governments can do, such as prohibiting the arrest of a person without sufficient cause. In most countries such as the United States, India, and Singapore, constitutional law is based on the text of the document ratified at the time the nation came into existence. There are some other constitutions, especially those of the United Kingdom, rely heavily on unrelated rules, as many legislative statutes and constitutional conventions differ in their position within constitutional law, and in some cases the terms of the conventions, there is tough competition.

State and legal structure

Constitutional laws can be regarded as second-order rule-making or rules regarding the exercise of power. It regulates the relationship between the judiciary, the legislature, and the executive with the bodies under its authority. One of the major functions of the Constitution in this context is to indicate the hierarchy and relations of power. For example, in a unitary state, the constitution would vest final authority in a central administration and legislature, and the judiciary, although there is often delegation of power or authority to local or municipal authorities. When a constitution establishes a federal state, it will identify several levels of government with exclusive or shared jurisdiction to make, enforce, and enforce laws.
