A constitution is not merely a collection of dry legal rules; it is the foundational covenant of civilized social existence. In a large, diverse society, a constitution performs five primary functions:
- 1. Coordination and Assurance: In a diverse nation with millions of citizens of different religions, castes, professions, and interests, chaos would reign unless everyone is assured that basic rules are agreed upon and legally enforceable. Function 1: To provide a set of basic rules that allow for minimal coordination amongst members of a society.
- 2. Allocation of Decision-Making Powers: Specifies who gets to decide what laws are made (e.g., in a democracy, the Parliament elected by the people). Function 2: To specify who has the power to make decisions in society and decide how the government will be constituted.
- 3. Setting Inviolable Limits on Government Power: Prevents the government from degenerating into a tyranny. Even a democratically elected government cannot arbitrarily throw citizens into prison without trial, ban a religion, or silence the press. Function 3: To set some limits on what a government can impose on its citizens through Fundamental Rights.
- 4. Fulfilling Societal Aspirations: Contemporary constitutions do not just limit power; they empower the state to eradicate social evils (untouchability, poverty) and build a just society. Function 4: To enable the government to fulfill the aspirations of a society and create conditions for a just society (Directive Principles).
- 5. Expressing National & Moral Identity: Defines who belongs to the political community and establishes the fundamental moral commitments of the nation.
