LEGAL PRINCIPLE: CIVIL PROCEDURE – Amendment of Pleadings – Amendment on Appeal to Prevent Injustice
PRINCIPLE STATEMENT
It is well established that leave to amend may be made and granted at any stage of the proceedings; it is however important to seek such leave as soon as the defect in the proceedings is detected; notwithstanding this guide, an amendment may be sought, and if appropriate, granted on appeal, if it is to amend the record of the trial court in line with the fact proved before the trial court and the decision; this power is to be exercised to prevent the occurrence of substantial injustice.
RATIO DECIDENDI (SOURCE)
"It is well established that leave to amend may be made and granted at any stage of the proceedings. See Totty v. Effiong Udofia & Anor (1966-67) 10 ENLR 45. It is however important to seek such leave as soon as the defect in the proceedings is detected. Notwithstanding this guide, an amendment may be sought, and if appropriate, granted on appeal, if it is to amend the record of the trial court in line with the fact proved before the trial court and the decision. This power is to be exercised to prevent the occurrence of substantial injustice — See Metal Construction (W.A.) Ltd. & Ors. v. Miglore & Anor (1976) 6-9 SC 163, 171-172; Karimu Laguro & Anor v. Toku and Anor (1992) 2 NWLR (Pt.233) 278."
EXPLANATION / SCOPE
This comprehensively states appellate amendment doctrine. General rule: Leave to amend may be granted at any stage—including appeal. Best practice: Seek leave promptly when defect detected—don’t delay unnecessarily. Appellate amendment permitted when: (1) Amending record to align with facts proved at trial; (2) Conforming pleadings to decision reached; (3) Preventing substantial injustice. “At any stage” means: trial, post-trial, or appeal—no absolute bar at any point. “Important to seek…as soon as detected” means: promptness expected but delay doesn’t automatically bar relief. Purpose of appellate power: Prevent substantial injustice—ensuring technical pleading defects don’t defeat meritorious cases. “Line with fact proved” means: evidence was led at trial supporting amendment, decision based on that evidence, and amendment merely formalizes what occurred. This serves: substance over form, preventing injustice from technical defects, and ensuring cases decided on merits not pleading technicalities. When appropriate on appeal: Evidence supports amendment, no prejudice to opponent (evidence already addressed), and injustice would result from refusing. “Substantial injustice” means: serious unfairness, defeating meritorious case on technicality, or denying relief despite proof. Courts balance: importance of prompt amendment-seeking against preventing injustice from technical defeats. The principle: appellate courts can and should amend to prevent substantial injustice when amendment aligns pleadings with proved facts.
