What Happened
- Five Rajya Sabha seats from Bihar are going to polls on March 16, 2026.
- The NDA alliance, with 202 MLAs in the 243-member Bihar Assembly, has sufficient strength to comfortably win four seats but falls short of the votes needed for a fifth.
- RJD (Rashtriya Janata Dal) has fielded A.D. Singh as its candidate for the contested fifth seat.
- With 41 votes required per seat (the Quota), NDA's residual vote pool after securing four seats stands at approximately 38 — three short of the quota.
- The opposition INDIA/Grand Alliance bloc has 35 MLAs (RJD-led), with AIMIM holding 5 seats and BSP holding 1 — these "Other" MLAs become kingmakers for the fifth seat.
- The contest has raised significant discussion about Single Transferable Vote mechanics, open ballot provisions, and the possibility of cross-voting.

Article 80 and Rajya Sabha Elections: Composition and Method
Article 80 of the Constitution governs the composition of the Council of States (Rajya Sabha). Members representing states are elected by the elected members of the respective State Legislative Assemblies using the system of Single Transferable Vote (STV) by proportional representation.
- Article 80(1): The Rajya Sabha shall consist of not more than 238 representatives of states and UTs, plus 12 nominated members.
- Method: Proportional representation by Single Transferable Vote (STV).
- Open ballot system: In Rajya Sabha elections, voting is by open ballot — each elector must show their ballot to their party's authorised agent before depositing it.
- Quota formula: Quota = (Total valid votes ÷ (Seats + 1)) + 1.
- Bihar has 243 Assembly seats; for 5 Rajya Sabha seats: Quota = (243 ÷ 6) + 1 = 41.5, rounded to 41 (first-preference votes needed to win one seat).
Connection to this news: NDA with 202 MLAs can fill four seats (4 × 41 = 164 votes needed; residual = 38 votes). The fifth seat requires 41 votes — NDA needs 3 more; RJD-led INDIA bloc needs 6 MLAs from AIMIM/BSP to back it. The arithmetic makes the fifth seat a genuine contest.
Single Transferable Vote (STV) System
STV is the method used for Rajya Sabha elections. Unlike first-past-the-post, STV allows voters to rank candidates in order of preference, and votes are redistributed according to a quota system until all seats are filled.
- Voters mark preferences as 1, 2, 3, etc. on the ballot (ranking candidates).
- A candidate who reaches the Quota on first preferences is elected.
- Surplus votes (above the Quota) of an elected candidate are redistributed to next preferences.
- If no candidate reaches the Quota, the candidate with the fewest votes is eliminated and their votes redistributed.
- This process continues until all seats are filled.
- Rajya Sabha elections use an open ballot — a unique exception to the secret ballot principle — to prevent cross-voting by party MLAs.
Connection to this news: The fifth seat outcome will depend on how AIMIM (5 MLAs) and BSP (1 MLA) distribute their first-preference votes. STV mechanics mean that residual votes after the first four seats are determined will flow to the fifth seat contest.
Cross-Voting and the Anti-Defection Law
Cross-voting — when elected legislators vote against their party's official line — is a recurring feature of Rajya Sabha elections. Unlike Lok Sabha or state assembly votes on motions of confidence, the Tenth Schedule (anti-defection law) does not apply to Rajya Sabha elections, which are treated as elections rather than votes within the House.
- The Tenth Schedule (52nd Constitutional Amendment, 1985) disqualifies an MP/MLA if they vote against the party whip in a division vote inside the legislature.
- Supreme Court in Kihoto Hollohan v. Zachillhu (1992) upheld the Tenth Schedule; the Speaker/Chairman is the deciding authority for disqualification.
- However, the SC has held that the anti-defection law does not apply to elections — Rajya Sabha elections are electoral processes, not legislative votes.
- As a result, an MLA can technically vote for a candidate from another party in a Rajya Sabha election without being disqualified under the Tenth Schedule.
- Parties use the open ballot provision to verify loyalty — a departing vote is visible to party agents.
Connection to this news: Even under the open ballot system, AIMIM and BSP MLAs are under no anti-defection obligation in Rajya Sabha elections. Their choice of first preference will likely decide whether NDA or the opposition wins the fifth seat.
Bihar Legislative Assembly: Composition and NDA Dominance
Bihar's 2025 state assembly elections (November 2025) resulted in a strong NDA mandate. The updated MLA tally is central to the Rajya Sabha election arithmetic.
- Bihar Legislative Assembly: 243 total seats.
- NDA: approximately 202 MLAs (BJP + JD(U) + other NDA allies).
- Opposition INDIA/Mahagathbandhan: approximately 35 MLAs (RJD-led).
- Others: AIMIM (5 MLAs), BSP (1 MLA).
- Five Rajya Sabha seats from Bihar are going to polls on March 16, 2026.
- Bihar sends 16 members to the Rajya Sabha in total; seats retire in batches based on six-year terms.
Connection to this news: NDA's 202 MLAs give it an overwhelming advantage for four seats. The fifth seat is genuinely contested because neither NDA's residual votes (38) nor the INDIA bloc's tally (35) alone crosses the 41-vote threshold — making the 6 "Other" MLAs the deciding factor.
