LEGAL PRINCIPLE: CRIMINAL LAW — Confessional Statements — Sufficiency for Conviction — Need for Corroboration
PRINCIPLE STATEMENT
A free and voluntary confession, if direct and positive, duly made and satisfactorily proved, is sufficient to ground a conviction; however, it is desirable to have some evidence, however slight, of circumstances making it probable that the confession was true.
RATIO DECIDENDI (SOURCE)
Per Ogwuegbu, JSC, in Emeka v. State (2001) NLC-72000(SC) at p. 8; Paras A–B.
"There is a long line of judicial authorities which establish that in Nigeria a free and voluntary confession by a person if direct and positive, duly made and satisfactorily proved, is sufficient to ground a conviction. It is however, desirable to have outside the appellant's confession to the police some evidence however slight, of the circumstances which made it probable that the confession was true."
EXPLANATION / SCOPE
A voluntary, direct, and positive confession can sustain a conviction without corroboration if the court is satisfied of its truth. However, corroboration—however slight—is desirable to test the confession’s truth. The judge must be satisfied of the confession’s voluntariness and truth. Corroboration is not legally mandatory but strengthens confidence in the conviction. The principle balances respecting confessions as powerful evidence with the need to guard against false ones. The court may convict on confession alone if satisfied, but should seek external supporting circumstances. The approach has been consistently affirmed. The desirability of corroboration is a rule of practice, not law.
