Technicality means a harmless error/mistake that does not go to the root of a case, see Olley v. Tunji (2013) 10 NWLR (Pt. 1362) 275. The “spirit of justice does not reside in form and formalities, nor in technicalities,” see Bello v. A.-G., Oyo State (1986) 5 NWLR (Pt. 45) 828 at 886, per Oputa, JSC; Omisore v. Aregbesola (2015) 15 NWLR (Pt. 1482) 205. Substantial justice and technical justice, arch enemies in adjudication, had been in a protracted imaginary battle on which to win and arrest the attention of the Nigerian Courts. However, in the process of the juridical duel, the case-law, rightly, intervened and slaughtered technicality and buried it deeply under the temple of substantial justice. To accede to the appellant’s request will be akin to resurrecting the deceased technicality.
