During this standstill, Pakistani raiders, with the support of the Pakistani Army, began advancing on Kashmir in October 1947. A panicked Maharaja invited Indian forces into Kashmir to provide temporary protection. Subsequently, the Maharaja executed an instrument of accession with India. Under the instrument, defence, external affairs, and communications were listed under the exclusive domain of the central government. All other plenary powers would remain vested within the state government.
Kashmir and the Indian Constitution
Article 370 limits the authority of Parliament to pass legislation for the State of Jammu and Kashmir. Under Articles 370 (1) (b) and 370 (1) (d), the Parliament has to confine legislation affecting the state to areas enumerated in a list attached to the Instrument of Accession. Legislation on other matters can be passed only if it is explicitly concurred to by the Government of Jammu and Kashmir. Under Article 370 (3), the President can modify or even repeal Article 370. However, this could be done only with the concurrence of the Constituent Assembly of the state.
