Discuss the constitutional basis and electoral method for Rajya Sabha elections. How do casual vacancy bypolls differ from biennial retirement elections?

The Rajya Sabha is the constitutional expression of Indian federalism — a permanent, indirectly elected chamber in which States are represented through their legislatures rather than the electorate directly. Its composition and election method flow from Article 80, operationalised by the Representation of the People Act, 1951.

Constitutional basis

• Article 80(1) with the Fourth Schedule: maximum 250 members — up to 238 representing States and Union Territories, and 12 nominated by the President for literature, science, art and social service [1].
• Article 80(4): State representatives are elected by the elected members of the State Legislative Assembly [1].
• Article 83(1): the House is not subject to dissolution; one-third of members retire every second year, ensuring legislative continuity [1].
• Article 101(4): a seat may be declared vacant if a member is absent from all sittings for 60 days without permission [1].

Electoral method

• Proportional representation by single transferable vote, conducted by the Election Commission under the RPA, 1951 [2]; nominated MLAs have no vote.
• Voting is by open ballot since 2001 — an MLA must show the marked ballot to the party's authorised agent. It followed the S.B. Chavan Ethics Committee (December 1998) recommendation to curb money and muscle power, and was upheld in Kuldip Nayar v. Union of India (2006) [3]. The same amendment removed the domicile requirement [3].
• Results now often turn on technicalities — Haryana (2016), where 12 votes were invalidated over the pen used, and Gujarat (2017), where ballots shown to the wrong agent were cancelled [4].

Bypolls versus biennial elections

• Biennial polls are scheduled and term-driven, filling seats of retiring members; the winner gets a full six-year term.
• Bypolls fill a casual vacancy from death, resignation or disqualification, and must be held within six months where the unexpired term exceeds one year; the winner serves only the residual term [2].

Thus the Upper House balances continuity with periodic renewal. Strengthening it now requires less a stricter statute than internal transparency within parties in candidate selection [4], alongside fuller use of Article 101(4) to make attendance a genuine accountability test.
