Background
The appellant, Ape Aja, alongside co-accused, was charged and convicted by the High Court of Ogun State for conspiracy to commit armed robbery and armed robbery. The crimes involved the robbery of the victims using dangerous weapons and sexual assault on some victims including minors. The appellant denied the charges and raised a defence of alibi, claiming he was at home sleeping during the offences. The trial court convicted him and sentenced him to death. The Court of Appeal upheld the conviction. The appellant petitioned to the Supreme Court, contending that his alibi was improperly rejected and that a miscarriage of justice occurred.
Issues
- Whether the defence of alibi raised by the appellant was properly considered and if it should have succeeded.
- The correct legal approach to concurrent findings of fact by lower courts in criminal cases.
Ratio Decidendi
- Meaning and effect of alibi: An alibi asserts the accused was elsewhere at the time of the crime, making it physically impossible to have committed the offence. A successful alibi results in acquittal.
- Duty to raise and particularize alibi promptly: An accused must raise the defence at the earliest opportunity, preferably during police interrogation, providing sufficient particulars (whereabouts, time, persons present) to enable investigation.
- Prosecution's burden regarding alibi: If an alibi is properly raised, the prosecution must investigate and disprove it. Failure to do so can create reasonable doubt, except where evidence conclusively fixes the accused at the crime scene.
- Concurrent findings of facts: The Supreme Court defers to concurrent factual findings by lower courts unless they are perverse, unsupported by evidence, or a miscarriage of justice is evident.
- Evidence of victims as eyewitnesses: Victim testimony qualifies as eyewitness evidence and is strong in establishing identity.
Court Findings
The Supreme Court found that although the appellant raised an alibi, he failed to provide sufficient particulars for police investigation—for example, not naming who was with him or giving credible evidence to back his claim. Contrasting this, the victims (who knew the appellant before) gave credible and consistent eyewitness testimony, identifying him positively. The evidence from the prosecution overwhelmingly placed the appellant at the crime scene. This evidence demolished the alibi defence. The concurrent findings by the trial and appellate courts were supported by the evidence and not perverse.
Conclusion
The Supreme Court dismissed the appeal, affirming the conviction and death sentence. The court held that the defence of alibi was not properly established and was effectively rebutted by credible eyewitness identification. The concurrent findings of fact by the lower courts were neither perverse nor unjust.
Significance
This case reaffirms key principles governing the defence of alibi in Nigerian criminal law: the necessity of timely and particularized alibi claims, the prosecution’s duty to investigate raised alibis, and the high evidential value of victim eyewitness testimony. It clarifies that failure to provide sufficient particulars can lead to the defence failing, especially when strong eyewitness evidence is present. The decision underscores the Supreme Court’s respect for concurrent factual findings by lower courts absent clear errors, guiding future appeals involving alibi defences.
