Having said that may I state that by virtue of Section 235 of the Constitution of the Federal Republic of Nigeria, 1999 (as amended), the Supreme Court cannot sit on appeal over its own judgment. The provision gives a stamp of finality to any decision of the Supreme Court. There is no constitutional provision for the review of the judgment of the Supreme Court by itself. See Eleazor Obioha v. Innocent Ibero and Anor (1994) 1 NWLR (pt.322) 503. However, it has been held by this court that the Supreme Court possesses inherent power to set aside its judgment in appropriate cases but that such inherent jurisdiction cannot be converted into an appellate jurisdiction as though the matter before it is another appeal, intended to afford the losing litigants yet another opportunity to re-state or re-argue their appeal.
