The Supreme Court has original jurisdiction over disputes between states or between states and the central government according to Article 131. This was deemed important because conflicts are likely in India's quasi-federal system. Original jurisdiction is exclusive to the Supreme Court and covers disputes involving legal rights between the listed parties. However, it does not extend to matters arising from pre-existing treaties or agreements, inter-state water disputes, or issues referred to commissions. The dispute must assert a legal right and not merely be a political matter.
