The question asks for the statement that is *not* correct in respect of the States of India.
Statement A is correct: States in India cannot have their own Constitutions separate from the Constitution of India. The Constitution of India is the supreme law applicable to all states.
Statement B was correct before August 2019: The State of Jammu and Kashmir had its own Constitution, adopted in 1956, under the special provisions of Article 370. This is no longer the case after the abrogation of Article 370. However, considering the timeframe of UPSC questions (often based on established facts prior to recent changes), this statement was historically correct for a State of India.
Statement C is correct: States in India do not have the right to secede from the Union of India. The Union is considered indestructible.
Statement D is not correct: The maximum number of members in the Council of Ministers of Delhi is fixed at ten percent (10%) of the total number of members in the Legislative Assembly by Article 239AA(4). The 15% limit was introduced by the 91st Amendment Act, 2003, but it applies to the Council of Ministers of states (except Delhi, for which a specific limit exists). Delhi is a Union Territory with a legislative assembly, not a full State.
Given the options, statement D is definitively incorrect as per the specific constitutional provision for Delhi, whereas statement B, while no longer true, was a correct historical fact about a State of India.
– India has a single Constitution applicable to all states (with historical exceptions like J&K).
– States cannot secede from the Union.
– The size of the Council of Ministers in states is generally limited to 15% of the Assembly strength (by the 91st Amendment).
– For Delhi specifically, the limit for the Council of Ministers is 10% of the Assembly strength.
The 91st Amendment Act, 2003, aimed to limit the size of the Council of Ministers and prevent large ministries. It inserted clause (1A) into Article 164 regarding the size of the Council of Ministers in states, setting the 15% cap (with a minimum of 12 members). For Delhi, Article 239AA governs its status as a Union Territory with special provisions, including the 10% limit on the Council of Ministers size.
