How does the extent of a legal right factor into the Supreme Court's original jurisdiction?
The extent of a legal right factors into the Supreme Court's original jurisdiction in cases where there is a dispute between the Government of India and one or more States, between the Government of India and any State or States on one side and one or more other States on the other, or between two or more States. If and in so far as the dispute involves any question (whether of law or fact) on which the existence or extent of a legal right depends, then the Supreme Court has original jurisdiction to hear and decide the case.
