Distinguish between the Inter-State Council and Zonal Councils in terms of legal basis, composition and functions. How effective have Zonal Councils been in addressing regional disputes?

India's federal architecture rests on two parallel coordination forums — the constitutionally-mandated Inter-State Council under Article 263 [1] and the statutory Zonal Councils created by the States Reorganisation Act, 1956 [2]. Both serve cooperative federalism, but differ sharply in status, scale and reach.

Legal basis

• Inter-State Council: constitutional — Article 263 empowers the President to establish it; constituted in 1990, serviced by a permanent Secretariat since 1991 [1].
• Zonal Councils: statutory, not constitutional — five councils (Northern, Central, Eastern, Western, Southern) set up under Sections 15–22 of the States Reorganisation Act, 1956 [2], a frequent point of confusion.

Composition

• ISC: national in scope — Prime Minister as Chairman, all Chief Ministers, UT Administrators, and six Union Cabinet Ministers; a Standing Committee under the Home Minister screens the agenda [1].
• Zonal Councils: regional — Union Home Minister is ex-officio Chairman of all five; member CMs rotate annually as Vice-Chairman. The Southern Zonal Council covers Andhra Pradesh, Karnataka, Kerala, Tamil Nadu and Puducherry [2].

Functions

• ISC: inquiry into and advice on inter-state disputes, investigation of subjects of common interest, and recommendations for better policy coordination — the wider Centre-State mandate [1].
• Zonal Councils: zone-specific coordination on border, water-sharing, transport, security and reorganisation-related matters; the Secretariat also follows up on implementation of recommendations [2].

Effectiveness — a mixed record

• Strengths: regular, sustained functioning — the Southern Zonal Council met at Tirupati (2021), Thiruvananthapuram, and most recently the 31st meeting at Mahabalipuram on 20 August 2026 chaired by the Union Home Minister [3]. Smaller zonal size permits frank, faster resolution of bilateral irritants than the unwieldy full ISC.
• Limits: recommendations are purely advisory and non-binding; hard disputes — river waters, boundaries — migrate to tribunals and the Supreme Court; meetings historically remain irregular relative to statutory expectation.

Zonal Councils have thus proved better at dispute prevention and administrative smoothing than at final adjudication. Institutionalising fixed annual calendars, transparent action-taken reports and closer ISC–Zonal Council linkage — as urged by the Punchhi Commission on strengthening federal consultative machinery — would convert these platforms into genuine engines of the cooperative federalism the Constitution envisages.
