How has the scope of the Supreme Court's original jurisdiction changed since its inception?
The scope of the Supreme Court's original jurisdiction has changed in that it now includes disputes 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, and between two or more States. This change was made by the Constitution (Ninety-ninth Amendment) Act, 2014, which added Article 131(a), (b), and (c). However, this amendment was struck down by the Supreme Court in the case of Supreme Court Advocates-on-Record Association and another vs. Union of India in its judgment dated 16-10-2015, AIR 2016 SC 117.
