1. Introduction
The terms Constitution and Constitutionalism are related but distinct. A Constitution is the fundamental legal document of a State that defines its political structure, allocates powers, and guarantees rights. Constitutionalism, however, is the philosophy that government powers must be limited and exercised in accordance with the Constitution, ensuring accountability, rights protection, and the rule of law.
2. Meaning of Constitution
A Constitution is the supreme law of a country. It lays down the framework for governance, the composition of different organs of the State, the distribution of powers between them, and the rights and duties of citizens. It can be written (India, USA) or unwritten (UK).
