According to Article 368 of the Indian Constitution, states in India are required to ratify only those Constitutional Amendment bills which concern with subject-matters listed in sub-clauses (a) to (f) of clause (2) there.
The 126th Constitutional Amendment Bill makes changes only in Article 334 of the Constitution and this article is outside the subject-matters in aforesaid sub-clauses. So why do Indian State legislatures keep ratifying this Bill?
Per an article in The Hindu:
The Punjab Assembly on Friday unanimously passed a motion to ratify the 126th Constitutional amendment to extend reservation for the Scheduled Castes and the Scheduled Tribes in Punjab for another 10 years.
Moving a motion in the House, Chief Minister Amarinder Singh said the two-day session had been specially convened for the extremely important agenda of ratifying the amendments to the Constitution of India, falling within the purview of clause (d) of proviso to clause (2) of Article 368, in line with the Constitution (126th Amendment) Bill, 2019, as passed by the both Houses of Parliament.
But clause (d) of proviso to clause (2) deals with "representation of states in Parliament". How does the Bill affects representation of states in Parliament at all?
Financial Express has it explained here that the Bill doesn't requires ratification from the states, yet here we are, articles popping up every other day that X state assembly ratified the aforesaid Bill.
