Q. Examine how the separation of powers is practised in India compared to the rigid presidential model of the United States of America. In this context, compare the actual authority of the Indian Prime Minister with that of the President of the USA.

Model Answer: 

While the US Constitution enforces a rigid tripartite separation of powers (Articles I–III), India adopts Montesquieu’s doctrine flexibly, combining functional overlap and executive-legislative fusion with checks and balances (Ram Jawaya Kapur, 1955).

Separation of Powers: India vs. USA

• Institutional Model: The US enforces strict personnel separation (Executive cannot sit in Congress); India mandates executive membership within the legislature (Article 75(5)).
• Checks and Balances: The US relies on structural vetoes (Senate confirmations, presidential veto); India operates on continuous legislative accountability (Article 75(3), Question Hour) and judicial review (Kesavananda Bharati).
• Judicial Delineation: India constitutionally separates the judiciary from the executive (Article 50), yet allows functional overlap through delegated legislation and tribunals, unlike the rigid US model (Marbury v. Madison).

Authority Matrix: Indian PM vs. US President

• Legislative Dominance: An Indian PM with a majority controls the legislative agenda via party whips and anti-defection laws (10th Schedule); the US President cannot introduce bills directly and frequently faces divided government gridlock.
• Appointments and Treaties: The US President requires Senate “advice and consent” for treaties and judicial/cabinet appointments; the Indian PM exercises de facto unilateral discretion through presidential aid and advice (Article 74).
• Tenure and Survival: The US President has a fixed four-year tenure immune to legislative confidence; the Indian PM’s authority depends on sustaining a majority in the Lok Sabha.
• Emergency and War Powers: The Indian PM can invoke centralized constitutional emergencies (Articles 352, 356); the US President acts as Commander-in-Chief but remains constrained by Congressional funding and the War Powers Resolution (1973).

An Indian Prime Minister backed by a parliamentary majority exercises far greater legislative mastery, whereas the US President commands greater institutional independence and unilateral executive autonomy.
