'Advisory' and 'Revisory' Jurisdiction of the Supreme Court.

ADVISORY JURISDICTION — the President may refer to the Supreme Court any question of law or fact of public importance and seek its opinion. The Court may report its opinion after such hearing as it thinks fit, but the opinion is ADVISORY ONLY: it is not binding on the President, and the Court may also decline to give one.

REVISORY JURISDICTION — the Supreme Court may REVIEW ITS OWN judgement or order and correct an error in it. Under Article 137 it has power to review any judgement pronounced by it, so that a mistake may be set right by the Court itself rather than being left to stand.

Four marks, two for each term, so each needs a full explanation rather than a phrase. For ADVISORY, the mark candidates lose is the limitation: the opinion is NOT BINDING. Note also that only the PRESIDENT may seek it, and only the Supreme Court has this jurisdiction — High Courts do not. For REVISORY, the essential words are "its OWN judgement". Do not confuse it with Judicial Review, which tests the constitutionality of a LAW, or with Appellate Jurisdiction, which hears appeals from LOWER courts. That three-way distinction is the point of the question.
