In 1972, the then current border between the Indian and Pakistani controlled parts of Kashmir was designated as the "Line of Control". This line has remained unchanged since the 1972 Simla Agreement, which bound the two countries "to settle their differences by peaceful means through bilateral negotiations". Some political experts claim that, in view of that pact, the only solution to the issue is mutual negotiation between the two countries without involving a third party such as the United Nations. The 1974 Interim Constitution Act was passed by the 48-member Azad Jammu and Kashmir unicameral assembly.
