PRINCIPLE STATEMENT

The point that needs be emphasized is that this court being a final court of justice under the Constitution has no jurisdiction and cannot under any circumstances sit on appeal over its own decisions; once judgment is delivered, the Supreme Court is without power to sit on appeal or to review it, even by a full panel of that court; its decision or judgment is final and, therefore, not subject to an appeal or review by itself or by any other court.

EXPLANATION / SCOPE

Supreme Court’s constitutional status as “final court” means: No self-review: Cannot sit on appeal over own decisions—no jurisdiction for this. No circumstance allows it: Not even exceptional cases, compelling reasons, or alleged errors permit self-review. Full panel cannot review: Even larger panel of Supreme Court cannot review earlier Supreme Court decision. Absolute finality: Decisions are final—not subject to appeal to any court or review by Supreme Court itself. This flows from: Constitutional designation as “final” court, hierarchical structure requiring higher court for appeals, and finality principle. “Under any circumstances” means: no exceptions, no matter how compelling the case, and no matter the alleged error. Even if Supreme Court made clear error: it cannot review itself, parties have no further appeal, and decision stands as delivered. This serves: maintaining Supreme Court’s final status, preventing endless self-review, and ensuring true finality. The only remedies for Supreme Court errors are: extremely limited slip rule for clerical mistakes (not substantive errors—see Principle 546), or legislative correction if decision created unworkable law. This absolute rule maintains: Supreme Court’s constitutional finality, hierarchical integrity, and true closure in litigation. No court above Supreme Court exists to review it, and it cannot review itself—thus true finality.
