What is Constitutional Law?

Constitutional Law refers to the body of law that interprets and applies the Constitution of the United States. This field of law focuses on the structure, functions, and limitations of different government entities.

Key Components of Constitutional Law

Fundamental Principles

Constitutional Law is built on several fundamental principles, including:

  • Federalism: The division of power between the federal government and state governments.
  • Separation of Powers: The division of government responsibilities into distinct branches to limit any one branch from exercising the core functions of another.
  • Judicial Review: The power of courts to declare laws unconstitutional.
  • Individual Rights: The protection of individual freedoms and rights as outlined in the Bill of Rights.

Separation of Powers

One of the cornerstone principles of Constitutional Law is the separation of powers. This principle ensures that the legislative, executive, and judicial branches of government each have distinct and independent powers.

Legislative Branch

Makes the laws

Importance of Judicial Review

Judicial review is a significant aspect of Constitutional Law. It allows courts to assess the constitutionality of legislative and executive actions. This principle was established in the landmark case Marbury v. Madison.
