Jurisdiction' is the power that a court of law exercises to carry out judgements and enforce laws. The Supreme Court is the protector and the final interpreter of the Constitution. It has both original and appellate jurisdiction as well as advisory jurisdiction.
Original Jurisdiction means the power to hear and determine a dispute in the first instance; i.e., those cases which cannot be moved in any other court other than the Supreme Court.
Appellate jurisdiction is the power of a higher court to review decisions and change outcomes of decisions of lower courts.
The Supreme Court has advisory jurisdiction (to give its opinion) on any question of law or fact of public importance as may be referred to it for consideration by the President.
