Comparison of Constitutions

02 Jul, 2026 Samyak IAS

A constitution lays down the basic structure, powers and limits of government. Different countries follow different constitutional models. The Indian Constitution is written, detailed, federal with a unitary bias, and follows the parliamentary system. The U.S. Constitution is written, brief, rigid and based on the presidential system with strict separation of powers. The British Constitution is largely unwritten and based on conventions, statutes and judicial decisions, with parliamentary sovereignty. Thus, while constitutions differ in form and structure, their common purpose is to ensure governance, rights protection and rule of law.
