Article 370 ?
Article 370 cannot be practically revoked. Jammu and Kashmir’s treaty of accession is linked to that, and legally, revoking 370 means revoking that treaty and making Jammu and Kashmir an independent nation.
In October 2015, the High Court of Jammu and Kashmir has ruled that the Article 370 cannot be "abrogated, repealed or even amended." ... On 3 April 2018, the Supreme Court of India gave a similar opinion declaring that the Article 370 has acquired a permanent status.
