High-yield facts
  • Constituent Assembly members were indirectly elected; strength fell from 389 to 299 after Partition.
  • Original Constitution: 395 Articles, 22 Parts, 8 Schedules; now 25 Parts, 12 Schedules.
  • Provisions on citizenship and elections came into force on 26 November 1949 (Article 394).
  • Assembly chaired as a legislature by G.V. Mavalankar; constitutional adviser B.N. Rau.

Traps

Common confusions
  • Ambedkar chaired the Drafting Committee, not the Assembly.
  • 1919 = provincial dyarchy; 1935 = proposed central dyarchy, never implemented.
  • Ireland gave DPSP; the USSR gave Fundamental Duties.
  • The Preamble can be amended — subject to the basic structure.
