The slogan ‘double engine’ gained prominence in the 2019 Lok Sabha elections, referring to the political alignment of the same party governing both the Union and the state. The Bharatiya Janata Party (BJP)-led National Democratic Alliance (NDA) won 303 out of 543 Lok Sabha seats, with 18 states under BJP governments, enabling claims of a ‘double engine’ for accelerated development (Election Commission of India, 2019). While politically effective, this concept raises significant federal questions about the constitutional balance between the Centre and states, challenging the cooperative federalism framework enshrined in the Indian Constitution.

Constitutional Framework Governing Federalism

The Indian Constitution delineates legislative and fiscal powers between the Union and states through Article 246 and the Seventh Schedule, which divides subjects into Union, State, and Concurrent Lists. Article 254 addresses repugnancy of laws, ensuring Union law prevails in case of conflict. Article 280 mandates the Finance Commission to recommend tax revenue distribution, ensuring fiscal balance. The 73rd and 74th Amendments empower local governance, reinforcing the federal structure. The Supreme Court in S.R. Bommai v. Union of India (1994) emphasized the federal nature of the polity and state autonomy, limiting arbitrary central intervention.

• Article 246: Defines distribution of legislative powers.
• Article 254: Resolves conflicts between Union and State laws.
• Article 280: Establishes Finance Commission for fiscal federalism.
• 73rd and 74th Amendments: Strengthen Panchayati Raj and Urban Local Bodies.
• S.R. Bommai case: Judicial safeguard for federalism and state governments.

Fiscal Federalism and Political Alignment

The 15th Finance Commission (2020-25) allocated ₹10.1 lakh crore to states, incorporating performance-based incentives. Data indicates states politically aligned with the Centre receive 5-10% higher grants (15th Finance Commission Report, 2020). For example, Maharashtra received ₹4.5 lakh crore in 2023-24, while Bihar, an opposition-ruled state, got ₹1.2 lakh crore (Union Budget 2023-24). PRS Legislative Research (2022) reports delays of 15-20% in central project clearances for opposition states, reflecting fiscal and administrative disparities linked to political alignment.

• States aligned with the Centre get higher performance-based grants.
• Union Budget 2023-24: ₹1.97 lakh crore grants-in-aid to states, 12% increase over previous year.
• Opposition-ruled states face delays in project approvals.
• India’s fiscal federalism index ranks 4th globally but shows skewed transfers (World Bank, 2023).

Institutional Mechanisms and Their Limitations

Key institutions managing Centre-state relations include the Finance Commission of India, which recommends equitable revenue sharing; NITI Aayog, facilitating cooperative federalism through policy coordination; the Election Commission of India, ensuring electoral fairness; the Inter-State Council (ISC), a forum for dialogue; and the Supreme Court, adjudicating federal disputes. However, the ISC has convened only six times since 2010 (ISC Secretariat, 2023), indicating weak institutional dialogue. The absence of legally binding mechanisms to enforce equitable resource distribution or project approvals contributes to discretionary centralization, undermining cooperative federalism.

• Finance Commission: Constitutional body for fiscal federalism.
• NITI Aayog: Policy coordination between Centre and states.
• Election Commission: Regulates elections impacting federal dynamics.
• Inter-State Council: Rarely convened, weak federal dialogue.
• Supreme Court: Judicial arbiter of Centre-state conflicts.

Comparative Perspective: India vs Germany

Germany’s Basic Law (1949) establishes a strong federal system with constitutionally guaranteed revenue sharing and independent state taxation powers. The Länder receive approximately 42% of total tax revenues, compared to India’s 32%, enabling balanced regional development and minimizing political bias (OECD Fiscal Federalism Report, 2022). Germany’s institutionalized fiscal federalism contrasts with India’s discretionary political federalism, where fund allocation and project approvals often depend on political alignment rather than constitutional mandates.

Implications and Way Forward

The ‘double engine’ narrative risks undermining constitutional federalism by conflating political alignment with constitutional entitlement. This politicization of resource allocation and project approvals weakens institutional mechanisms designed for cooperative federalism. Strengthening the Inter-State Council, enforcing Finance Commission recommendations transparently, and insulating fiscal transfers from political considerations are necessary to restore balance. Judicial vigilance, as in S.R. Bommai, must continue to check arbitrary centralization. Ultimately, federalism requires institutional safeguards beyond electoral arithmetic.

• Ensure legally binding enforcement of Finance Commission recommendations.
• Revitalize Inter-State Council as a regular federal dialogue forum.
• Insulate central grants and project approvals from political bias.
• Strengthen judicial oversight of federal disputes.
• Promote fiscal decentralization with enhanced state taxation powers.
