Subject Specialist Commentary
Analytical perspective & practical exam advice from the Master10 academic board
The separation of powers divides government authority into three distinct organs: the legislature to enact laws, the executive to administer them, and the judiciary to interpret them. Formulated by French philosopher Montesquieu in 1748, this framework prevents state tyranny by ensuring no single branch wields unchecked authority. Rather than creating isolated silos, modern democracies design overlapping checks and balances, allowing each branch to hold the others accountable and uphold constitutional freedom.
In UPSC Polity and State PSC exams, examiners constantly highlight the distinction between the American and Indian models. While the United States practices a rigid separation of powers, India follows a parliamentary system with functional overlap, where the executive is drawn directly from the legislature. Beware the prelims trap concerning Article 50: it mandates separating the judiciary from the executive in public services, but sits within the Directive Principles, not Fundamental Rights. Remember that Kesavananda Bharati confirmed this doctrine as an unalterable basic structure feature.
