A distinguishing aspect of Indian federalism is that unlike many other forms of federalism, it is asymmetric. Article 370 makes special provisions for the state of Jammu and Kashmir as per its Instrument of Accession. Article 371 makes special provisions for the states of Andhra Pradesh, Arunachal Pradesh, Assam, Goa, Mizoram, Manipur, Nagaland and Sikkim as per their accession or state-hood deals. Also one more aspect of Indian federalism is system of President's Rule in which the central government (through its appointed Governor) takes control of state's administration for certain months when no party can form a government in the state or there is violent disturbance in the state.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): What never happens with President's Rule?
unanswerable
