Constitutional Law is the body of law that defines the structure, powers, and functions of government institutions, and guarantees the fundamental rights of citizens. It forms the supreme legal framework for a country, ensuring that all laws and actions of the government conform to the principles enshrined in the constitution. Constitutional law provides the foundation for the functioning of the legal and political system. In India, the Constitution of India, which came into force on January 26, 1950, is the supreme law of the land. It outlines the framework for the country's legal and political structure and is a key document for ensuring democracy, federalism, justice, and fundamental rights for its citizens.
