Bihar

Bihar is a state of the Indian Union in the eastern Gangetic plain, constituted as a province on 22 March 1912 and reduced to its present boundaries on 15 November 2000 when eighteen southern districts were separated to form Jharkhand. It is among the most populous states in the Republic — 10.41 crore people at the 2011 Census, about 8.6% of India — and sends 40 members to the Lok Sabha, one of the largest state blocs in Parliament. Its legislature is bicameral: a 243-seat Vidhan Sabha and a 75-seat Vidhan Parishad, one of only a handful of states retaining an upper house. What structurally defines Bihar is the gap between its demographic weight and its fiscal base: the 2000 bifurcation took the mineral and industrial belt with it, leaving a state that carries roughly a twelfth of India's voters on one of the lowest per-capita incomes in the Union and a budget heavily dependent on Union transfers and borrowing.

Role

Bihar is a State List government in the full sense: it runs its own police and law and order, land and land revenue, agriculture and irrigation, public health, schooling and local government across 38 districts in 9 divisions. Its legislature is bicameral — a 243-seat Vidhan Sabha elected first-past-the-post for five years, and a 75-seat Vidhan Parishad that is a permanent body, one-third of whose members retire every two years, composed of 27 members elected by the Assembly, 24 from local authorities, 6 each from graduates’ and teachers’ constituencies and 12 nominated by the Governor. That second chamber is unusual: most Indian states abolished theirs, and Bihar’s survives in unbroken descent from the Council created with the province in 1912. In the Union, Bihar’s weight is electoral before it is economic. Forty Lok Sabha seats and 16 in the Rajya Sabha make it one of the largest state blocs in Parliament, and a state that held about 8.6% of India’s population at the 2011 Census with 88.7% of its people in rural areas exerts a pull on national policy — on reservation, on caste enumeration, on rural programmes — out of proportion to its output.

The structural fact about Bihar as a federal actor is the asymmetry the 2000 bifurcation created. The Bihar Reorganisation Act moved the mineral belt and the industrial corridor to Jharkhand and left the population behind, so the state now carries roughly a twelfth of the country’s voters on a GSDP the 2025-26 budget put at Rs 10.97 lakh crore and a per-capita income near the bottom of the Union. Its finances lean correspondingly on the Centre and on borrowing: the 2025-26 budget projected Rs 2.94 lakh crore of expenditure financed in part by Rs 32,918 crore of net borrowing, after a revised fiscal deficit of 9.2% of GSDP the year before. Bihar has pressed a standing claim for Special Category Status and, failing that, for project-specific packages — a negotiation that recurs at every Union budget and every Finance Commission. Alongside that fiscal dependence sits a record of the state using its own legislative room aggressively: statewide prohibition since 2016, left in force after the Supreme Court stayed a High Court ruling against it; a caste-based survey conducted on state authority in 2022-23; and a 65% reservation law built on that survey in November 2023 and struck down by the Patna High Court in June 2024. The state has also been the Election Commission’s proving ground — the first Special Intensive Revision of electoral rolls ran here in 2025, removed roughly 47 lakh names ahead of the November election, was upheld by the Supreme Court on 27 May 2026, and became the template for a nationwide exercise.

    Bihar carved out of the Bengal Presidency

    The province of Bihar and Orissa was constituted as a separate unit of British India, ending administration from Calcutta. A 43-member Legislative Council was created alongside it and first sat on 20 January 1913 — the institutional ancestor of the present Vidhan Parishad.

    Bihar Legislative Council constituted under the Constitution

    With the Constitution in force, Bihar was organised as a state of the Union with a bicameral legislature. The Council was constituted on 16 February 1950 as a permanent body not subject to dissolution; the first Legislative Assembly followed on 20 April 1952 after the first general election, with 331 members.

    Bihar Reorganisation Act splits off Jharkhand

    Parliament passed the Bihar Reorganisation Act in August 2000 and Jharkhand was constituted on 15 November 2000 from eighteen southern districts, including the Chota Nagpur mineral belt and the Dhanbad-Bokaro-Jamshedpur industrial corridor. Assembly strength fell from 331 to the present 243. The bifurcation left Bihar with most of the population and little of the resource base — the structural fact behind its fiscal position ever since.

    Hung assembly, President's rule and a re-run election

    The February 2005 election returned no majority; the assembly was dissolved and the state placed under President's rule. A fresh four-phase election in October-November 2005 produced a JD(U)-BJP majority and ended fifteen years of RJD-led government. Turnout was 45.85%.

    Statewide prohibition takes effect

    Bihar banned the manufacture, sale, storage and consumption of alcohol from 1 April 2016. The Patna High Court held the ban unconstitutional on 30 September 2016; the Supreme Court stayed that ruling on 7 October 2016 and the state re-enacted a stricter law on 2 October 2016 with non-bailable offences. A 2017 amendment let first-time offenders pay a Rs 50,000 fine in lieu of imprisonment. NFHS data record male alcohol use (ages 15-49) falling from 28.9% in 2015-16 to 17% in 2019-21, against a 6.8-point national decline.

    Reservation raised to 65% on caste-survey findings

    Acting on its own 2022-23 caste-based survey, the state legislature raised EBC reservation from 12% to 25% and OBC from 8% to 18%, with SC at 20% and ST at 2% — 65% in total, or 75% counting the 10% EWS quota, past the Supreme Court's Indra Sawhney ceiling. The state sought Ninth Schedule protection from the Union; it was not granted.

    Patna High Court strikes down the 65% reservation law

    The High Court held the amendments unconstitutional and voided the enhanced quotas in jobs and education. The judgment left the caste survey itself standing while removing the policy built on it, and the question of how far a state may legislate reservation off its own enumeration remains contested.

    State budget puts GSDP at Rs 10.97 lakh crore

    The 2025-26 budget estimated expenditure excluding debt repayment at Rs 2,94,075 crore against receipts excluding borrowings of Rs 2,61,357 crore, with a fiscal deficit target of 3% of GSDP (Rs 32,718 crore) after a 9.2% revised figure in 2024-25. GSDP was projected at Rs 10.97 lakh crore. Net borrowings of Rs 32,918 crore financed the gap.

    Polling on 6 and 11 November 2025 returned the NDA with 202 of 243 seats — BJP 89, JD(U) 85 — against 35 for the Mahagathbandhan, with the RJD at 25, its lowest since 2010. Turnout was 67.25%, roughly ten points above the previous election. The assembly was constituted on 20 November 2025.

    Supreme Court upholds the Bihar Special Intensive Revision

    The Election Commission ran the first Special Intensive Revision of electoral rolls in Bihar from June to September 2025, cutting the roll from 7.89 crore to 7.42 crore electors — about 47 lakh deletions, near 6% of the electorate — months before the assembly election. The exercise was contested through the campaign and extended nationwide from 27 October 2025. On 27 May 2026 the Supreme Court held it consistent with the Representation of the People Act and within the Commission's constitutional duty.
