The correct answer is Option 4- Supreme Court
The power to resolve federal disputes is entrusted to the Supreme Court of India.
Original jurisdiction means cases that can be directly considered by the Supreme Court without going to the lower courts before that. Cases involving federal relations go directly to the Supreme Court. The Original Jurisdiction of the Supreme Court establishes it as an umpire in all disputes regarding federal matters. In any federal country, legal disputes are bound to arise between the Union and the States; and among the States themselves. The power to resolve such cases is entrusted to the Supreme Court of India. It is called original jurisdiction because the Supreme Court alone has the power to deal with such cases. Neither the High Courts nor the lower courts can deal with such cases. In this capacity, the Supreme Court not just settles disputes but also interprets the powers of Union and State government as laid down in the Constitution. |
