Parliamentary system & federalism
How India fuses the Westminster parliamentary model with a federal structure, and why the Constitution leans toward a strong Union.
Why a parliamentary, not presidential, system
The framers deliberately adopted the Westminster parliamentary model over the American presidential one. Dr. B.R. Ambedkar, defending the choice in the Constituent Assembly on 30 December 1948, argued that a democratic executive must satisfy two conditions: stability and responsibility. The presidential system offers more stability but less responsibility; the parliamentary system offers more responsibility (daily accountability through questions, motions, and debates) at some cost to stability. India, he said, needed an executive answerable to the legislature day-to-day, given its diversity and the priority of avoiding authoritarian drift.
Features at the Union level
The parliamentary system is enshrined in Articles 74 and 75. Article 74(1) provides that there shall be a Council of Ministers headed by the Prime Minister to aid and advise the President, who shall act on that advice — the word 'shall' was inserted by the 42nd Amendment (1976) and the 44th Amendment (1978) added that the President may require reconsideration but must accept the advice tendered after reconsideration. Article 75(3) embodies collective responsibility: the Council of Ministers is collectively responsible to the Lok Sabha. Article 75(2) makes ministers hold office during the pleasure of the President; Article 75(1A), inserted by the 91st Amendment (2003), caps the Council at 15% of the Lok Sabha's strength.
The key markers are: a nominal head of state (President) distinct from the real executive (PM and Cabinet); a Cabinet drawn from and sitting in the legislature; collective responsibility; the leadership of the Prime Minister; and dissolution of the Lower House (Article 85). The same pattern is replicated in the States under Articles 163 and 164, with the Governor as nominal head and the Chief Minister as real executive.
Westminster with Indian modifications
India's system is not a carbon copy of Britain. The British model rests on parliamentary sovereignty; India has constitutional supremacy, with judicial review and a written Constitution. Britain has no formal head-of-state codification; India elaborates the President's powers in the text. Britain retains hereditary elements (the monarch, historically the Lords); India is a republic with an elected President (Article 54). The legal phrase 'Crown' has no Indian equivalent — sovereignty vests in 'We, the People' per the Preamble.
For the exam, fix the distinction between single citizenship (India, Article 5) and dual citizenship (USA), and note that India blends parliamentary government with a federal frame — a combination Britain lacks because the UK is unitary. The 'aid and advise' clause, the collective responsibility principle, and the 91st Amendment cap are the three most testable Union-level facts; at the State level, the analogous trio is Articles 163, 164, and the Governor's discretionary powers under Article 163(2).
