GST Council: The Weighted Voting Formula, and Why Its Recommendations Are Not Binding

The GST Council is a constitutional body, inserted by Article 279A via the 101st Amendment Act, 2016, and its voting formula is one of the most precisely-worded, and most-tested, mechanisms in the entire Constitutional Bodies cluster.

Composition

Article 279A(2) sets the Council's membership: the Union Finance Minister as Chairperson; the Union Minister of State in charge of Revenue or Finance as a Member; and the Minister in charge of Finance, Taxation, or any other Minister nominated by each State Government, one per state, as Members. The state-nominated Members separately choose one of their own number to be the Council's Vice-Chairperson for whatever period they decide (Article 279A(3)).

The weighted vote: one-third and two-thirds

This is the chapter's central fact. Under Article 279A(9), every decision needs a majority of not less than three-fourths of the weighted votes of the Members present and voting, and the weights themselves are fixed directly in the Constitution: the Central Government's vote carries one-third of the total weight, and all the State Governments' votes together carry the remaining two-thirds. No single state, and not even the Centre alone, can force a decision through: the Centre needs enough states on its side to clear three-fourths, and the states collectively cannot override the Centre either, since the Centre's one-third is enough to block a proposal on its own. The quorum for a meeting is one-half of the total membership (Article 279A(7)).

What the Council recommends on

Article 279A(4) lists the Council's recommendation powers in detail: which existing Union, State and local-body taxes get subsumed into GST; which goods and services are taxed or exempted; model GST laws and the principles behind inter-state supply and place-of-supply rules (linking to Article 269A); the turnover threshold below which GST does not apply; GST rates, including floor rates with bands; special rates to raise resources during a natural calamity or disaster; and special provision for a named list of states (the Northeastern states, plus Himachal Pradesh, Jammu and Kashmir, and Uttarakhand). The Council also recommends the date from which GST applies to petroleum crude, high-speed diesel, petrol, natural gas and aviation turbine fuel (Article 279A(5)): these five products are constitutionally within GST's scope already, but stay outside it in practice until the Council actually recommends bringing them in, which as of this writing it has not done.

Recommendations are not binding: Mohit Minerals (2022)

A single Supreme Court ruling reframed how this whole mechanism should be understood: in Union of India v Mohit Minerals Pvt Ltd (19 May 2022), a three-judge bench held that the GST Council's recommendations are not binding on Parliament or the state legislatures. The Court read Article 279A's own language (the Council only "recommends") together with Articles 246A, 269A and 279's continuing, undiminished legislative powers for both the Union and the states, and concluded that GST rests on shared, not hierarchical, sovereignty: the Council is a forum for negotiated consensus between coordinate legislatures, not a body whose word Parliament or an Assembly is bound to enact. A statement describing the Council as issuing binding directions to the Centre or the states is a direct, post-2022 factual error, not a matter of interpretation.

Article 279A(10): procedural defects do not invalidate Council action

A specific, exam-friendly clause worth knowing: no act or proceeding of the Council is invalidated merely because of a vacancy or defect in its constitution, a defect in a Member's appointment, or a procedural irregularity that does not affect the merits, mirroring similar validating clauses attached to other constitutional bodies in this book.

Quick revision points

• Article 279A, inserted by the 101st Amendment, 2016. Chairperson: Union Finance Minister. Members: Union MoS (Revenue/ Finance) plus one nominated Minister per state.
• Voting: three-fourths weighted majority; Centre = 1/3 weight, all states together = 2/3 weight. Quorum: one-half of members.
• Recommends the date petroleum crude, diesel, petrol, natural gas and ATF enter GST; none are in GST yet as of this writing.
• Mohit Minerals (2022): GST Council recommendations are advisory, not binding, on Parliament or state legislatures.
• Vacancies, appointment defects, or non-material procedural irregularities do not invalidate the Council's acts (Article 279A(10)).

The weighted-vote arithmetic and the Mohit Minerals holding are this chapter's two highest-yield facts; know both precisely rather than either in isolation, since a question can test the mechanism's design (the 1/3-2/3 split) or its legal effect (non-binding) as two separate angles on the same body.
