The territory of the units of the Indian federation may be altered by the parliament by a simple majority. Consent of the state legislative is not necessary before the parliament redistributes territory of the concerned state. The President’s consent is necessary for introducing a bill on redistributing territory of any state in the parliament.No specific time period within which states have to send their decision back to the centre has been mentioned in the Constitution. The central government can specify the time period while referring the matter. The Constitution does not mention that the state legislatures have to agree to the proposed creation/alteration of states. The Parliament can therefore, pass a law creating a new state even if affected states do not agree to the proposal.
