Bar on judicial interference in pre-constitution treaties restricts court jurisdiction over disputes arising from such instruments. The Article bars the Supreme Court and all other courts from jurisdiction over disputes arising from instruments entered into before the Constitution by a Ruler of an Indian State to which the Dominion Government or its predecessors were party, and over rights or liabilities arising under such instruments that have continued in operation after the Constitution's commencement, subject only to the advisory mechanism under Article 143; it defines 'Indian State' and 'Ruler' for this purpose.
