Discuss the constitutional mandate of the GST Council and evaluate its functioning as an instrument of cooperative federalism.

The GST Council, created under Article 279A by the 101st Constitutional Amendment Act, 2016, is India's first constitutionally mandated fiscal federal body — a forum where the Union and States pool sovereignty over indirect taxation [1]. Its record shows genuine consensus-building, but uneven Centre-State coordination.

Constitutional mandate

• Composition: chaired by the Union Finance Minister, with the Union Minister of State (Finance) and Finance Ministers of all States/UTs as members — institutionalising joint decision-making.
• Functions: recommends rates, exemptions, threshold limits, model GST laws and special provisions, complementing the concurrent taxing power under Article 246A [1].
• Voting design: decisions require a three-fourths majority, with the Centre holding one-third and States two-thirds of weighted votes — neither side can act alone.
• Compensation guarantee: the Amendment obliged the Centre to compensate States for revenue loss for five years [1].

Evaluation as an instrument of cooperative federalism

Strengths

• Overwhelmingly consensus-driven functioning; formal voting has been a rare exception.
• Delivered the "Next-Gen GST Reforms" (56th meeting, September 2025), collapsing four slabs into 5% and 18% with a 40% de-merit rate, effective 22 September 2025 [2][3].
• Simplified compliance for MSMEs and cut classification disputes, with rate relief on food, medicines and small two-wheelers [3][4].

Limitations

• Council recommendations are recommendatory, not binding (SC in Union of India v. Mohit Minerals, 2022), leaving compliance to political goodwill [5].
• Irregular meeting frequency — over a year separated the 56th meeting from the 57th convened on 12 September 2026 — weakens continuous dialogue [6].
• Loss of States' fiscal autonomy and post-compensation revenue anxiety remain unresolved friction points.
• Persisting administrative bottlenecks in registration and cancellation, now on the Council's reform agenda [6].

The Council has largely validated the constitutional wager that shared fiscal sovereignty can work. Institutionalising a fixed minimum meeting calendar, a dispute-resolution mechanism under Article 279A(11), and greater agenda transparency would deepen trust. Strengthened thus, the Council can remain the working model of the cooperative federalism the Constitution envisages.
