Adegoke Motors Ltd v. Dr. Adesanya & Anor (1986) 3 NWLR (Pt. 109) 250 at 274; (1989) 5 SCNJ 80, inter alia, thus; “We are final not because we are infallible; rather we are infallible because we are final, Justices of this Court are human beings, capable of erring. It will certainly be short-sighted arrogance not to accept this obvious truth. It is also true that this Court can do inestimable good through its wise decisions. Similarly, the Court can do incalculable harm through its mistakes. When therefore it appears to learned Counsel that any decision of this Court has been given per incuriam, such Counsel should have the boldness and courage to ask that such decision shall be over-ruled. This Court has the power to overrule itself (and has done so in the past) for it gladly accepts that it is far better to admit an error than to preserve an error.”
OBITER DICTA OF THE ULTIMATE COURT ON IMPORTANT POINTS ARE BINDING ON LOWER COURT
Although this opinion was given in a criminal appeal, it has been followed and applied by the Court of Appeal in many civil appeals against interlocutory decisions. See for an example Akinsola Dawodu & Anor. v. F. O. Ologundundu & Ors. (1986) 4 N.W.L.R. 104, at p.112. For, it has been held by the House of Lords in England that although what is ordinarily binding in a case is the ratio decidendi and not the obiter dictum; yet an obiter dictum by the ultimate court on an important point of law is one which is binding on and followed by all the lower courts: see W.B. Anderson & Sons Ltd. & Ors. v. Rhodes (Liverpool) Ltd. & Ors. (1967) 2 All E.R. 850. After all, a good deal of the important pronouncements of the Supreme Court in the famous case of Bronik Motors Ltd. & Anor. v. Wema Bank Ltd. (1983) 1 S.C. N.L.R. 296 was obiter. Yet it was binding on the Court of Appeal and all other courts lower down in the judicial hierarchy until the law was changed in Akinsanya v. U.B.A. Ltd. (1986) 4 N.W.L.R. 273.
