One Nation, One Election, Many Constitutional Questions: Federalism at the Ballot Box

The proposal for simultaneous elections to the Lok Sabha and State Legislative Assemblies, popularly described as “One Nation, One Election” (ONOE), has moved from a recurring electoral reform debate to a concrete project of constitutional amendment. The Constitution (One Hundred and Twenty-Ninth Amendment) Bill, 2024 proposes the insertion of Article 82A and amendments to Articles 83, 172 and 327 in order to synchronise parliamentary and State electoral cycles. The proposal is defended on grounds of administrative efficiency, reduction of election expenditure, continuity in governance, minimisation of repeated application of the Model Code of Conduct and greater policy stability. Yet its constitutional significance extends far beyond election management. It raises foundational questions concerning federalism, representative democracy, parliamentary accountability, State autonomy, premature dissolution of legislatures, the power of the Election Commission of India, the constitutional position of the President, and the Basic Structure Doctrine. This paper examines the historical evolution of simultaneous elections, the recommendations of the High Level Committee chaired by former President Ram Nath Kovind, the architecture of the 129th Amendment Bill, and developments before the Joint Parliamentary Committee up to October 2026. It argues that synchronisation is not unconstitutional merely because elections are held together; India itself followed substantially simultaneous electoral cycles until 1967. The constitutional difficulty lies instead in the mechanisms necessary to preserve synchronisation once political events produce different legislative lifespans. Curtailing elected State Assemblies, limiting governments elected after premature dissolution to a “remainder term”, and permitting postponement of a State election on the recommendation of the Election Commission potentially alter the working relationship between democratic accountability and federal autonomy. Drawing upon Supreme Court jurisprudence on democracy, federalism, constitutional amendment and free and fair elections, the paper concludes that electoral efficiency cannot by itself justify constitutional centralisation. Any simultaneous election framework must preserve the independent democratic mandate of the States, maintain legislative accountability and incorporate stringent safeguards against arbitrary postponement or manipulation of electoral cycles.
