A constitution is called the main law of land?

A constitution is referred to as the "main law of the land" because it establishes the fundamental legal framework and principles governing a nation or state. It outlines the structure of government, the distribution of powers, and the rights of citizens, serving as the supreme legal authority. All laws and policies must align with the constitution, ensuring that they uphold democratic values and protect individual rights. This foundational document plays a crucial role in maintaining the rule of law and guiding the functioning of the state.
