- Statement I: The GST Council is constituted under Article 279A of the Constitution (as inserted by the 101st Amendment Act, 2016). Article 269A deals with the levy and collection of GST in inter-state trade or commerce. - Statement II: The GST Council makes recommendations to the Union and State Governments on various issues related to GST, including rates, exemptions, thresholds, etc. This is correct. - Statement III: Voting in the GST Council is weighted. The Central Government has a weightage of one-third of the total votes cast, and the votes of all the State Governments taken together have a weightage of two-thirds. Decisions require a three- fourths majority of the weighted votes. Therefore, individual states do not have equal voting weight compared to the Centre, nor does an individual state's vote carry the same weight as the collective states' votes. The statement "Every state does not have an equal vote" is thus technically correct, but potentially misinterpreted in the question's context. - Statement IV: Decisions of the GST Council are taken by a majority of not less than three-fourths of the weighted votes of the members present and voting. This is correct.
