What Is Constitutional Law?

Constitutional law is the body of law that governs the operation and interpretation of the constitution of a given state or nation. It establishes the framework within which the government may exercise its authority, and sets out certain fundamental rights and principles that government must respect.

In some cases, constitutional law also protects individual citizens from arbitrary or excessive governmental action.

Most modern nation-states have some form of a written constitution, and constitutional law, therefore, plays an essential role in the legal systems of many countries.

Even in those nations that do not have a written constitution, constitutional principles may be enshrined in other sources of law, such as statutory law or common law.

This post discusses everything you need to know about constitutional law. Read on to learn more.

Constitutional Law: The History

The origins of constitutional law can be traced back to ancient Greece and Rome, where the concept of a higher law – a law that was not subject to change or repeal by ordinary legislative bodies – began to emerge.

The Greek philosopher Aristotle, for example, spoke of natural law – or the “law of nature” – which he believed to be a higher law that governed human beings and could be discerned through reason.

During the Middle Ages, the idea of a higher law continued to develop, with some thinkers positing that there was a divinely-ordained natural law that was superior to any earthly laws. This belief gave rise to the concept of “natural rights” – that is, rights inherent in all human beings and cannot be taken away by any government.

The idea of natural rights was later championed by the English philosopher John Locke, who argued that every individual has a right to life, liberty, and property. These ideas were influential in developing constitutional law in England and the United States.

In the United States, the constitution is supreme, and all other laws must conform to it. The constitution establishes the framework for the government and sets out certain rights and principles that the government must respect.

The constitution is not a static document; it is living and breathing, and it has been amended 27 times since it was originally ratified in 1788. Despite these amendments, the constitution remains the supreme law of the land, and it is the courts’ job to interpret its meaning.

What Are the Key Elements of Constitutional Law?

There are three key elements of constitutional law: the legislature, the executive, and the judiciary.

The legislature is the body of government responsible for making laws. The legislature is divided into two houses in most countries: the upper house and the lower house.

The upper house is usually made up of members of the aristocracy or the clergy, while the lower house is made up of elected representatives of the people.

The executive is the body of government responsible for administering laws. A president or prime minister typically heads the executive, including several departments and agencies responsible for different aspects of government.

The judiciary is the body of government responsible for interpreting the law. The judiciary is made up of several courts, which have the power to hear cases and render judgments.

What Are the Fundamental Principles of Constitutional Law?

There are several fundamental principles of constitutional law. These principles include:

1.     Separation of Powers

This principle dictates that the different branches of government – the legislature, the executive, and the judiciary – must be separate and independent from one another. The principle of separation of powers is designed to prevent anyone branch of government from having too much power.

2.     Checks and Balances

This principle dictates that each branch of government has checks and balances over the other branches.

For example, the legislature can pass laws, but the president has the power to veto those laws. The judiciary can declare laws unconstitutional, but the legislature can pass amendments to the constitution.

The principle of checks and balances is designed to prevent any branch of government from having too much power.

3.     Judicial Review

This principle dictates that the judiciary has the power to review and strike down laws that it deems to be unconstitutional. Judicial review is a key check on the power of the legislature and the executive, and it helps to ensure that the government respects the rights of individuals.

4.     Federalism

The principle of federalism dictates that the national government and the state governments share power. The federal government has certain powers, such as the power to make war.

The state governments have certain powers, such as the power to regulate commerce and to establish schools.

The principle of federalism is designed to ensure that the government respects the rights of the states and the people.

Does Constitutions Law Apply to Everyone?

Yes, constitutional law applies to everyone. The constitution is the supreme law of the land, and it establishes the framework for the government.

All laws must conform to the constitution, and all individuals – including the president and members of Congress – are bound by it.

The constitution protects the rights of all individuals, including the right to life, liberty, and the pursuit of happiness. It also establishes the government’s power to tax and regulate commerce.

Constitutional law is the foundation of every legal system, and it sets forth the basic principles that govern a country.

What Is the Difference Between Constitutional Law and Administrative Law?

Administrative law is the body of law that governs the activities of administrative agencies. Administrative law includes the rules and regulations that these agencies promulgate and the decisions of those agencies.

On the other hand, constitutional law is the body of law that governs the relationship between the government and the people. It includes the constitution, as well as the laws and court decisions that interpret it.

Constitutional law sets forth the principles that the government must follow, and it protects the rights of individuals. On the other hand, administrative law governs the day-to-day operations of administrative agencies.


In short, constitutional law is the branch of law that governs how a government can operate and what individual rights are protected. It is an essential part of any democracy and helps to ensure that all citizens are treated fairly.

While there are many different elements to constitutional law, the fundamental principles remain the same.
