Background
On 2013-05-08, the High Court of Ondo State at Akure arraigned Ogunleye Sanmi on two counts: conspiracy to commit armed robbery (section 6(b)) and armed robbery (section 1(2)(a)) under the Robbery and Firearms (Special Provisions) Act. He pleaded not guilty. The prosecution called three witnesses: a husband‐and‐wife pair (the victims) and the investigating police officer. A written statement by the appellant, deemed confessional and endorsed by a superior officer, was admitted as Exhibit A. The appellant denied authorship of that statement and testified, but called no additional witness. On 2014-01-27, the trial judge convicted him on both counts and sentenced him to death by hanging.
Sanmi appealed to the Court of Appeal, Akure Division. On 2016-07-01, that court unanimously dismissed his appeal for lacking merit. He then filed a further appeal to the Supreme Court.
Issues
The parties distilled the following key issues for Supreme Court determination:
- Whether Exhibit A was validly admitted and properly relied upon to uphold the conviction.
- Whether the defence of alibi raised by the appellant was afforded proper consideration and could avail him.
- Whether the appellant’s grounds and issues of appeal were competently drafted and within the Court of Appeal’s jurisdiction.
- Whether the prosecution proved its case beyond reasonable doubt.
Ratio Decidendi
The Supreme Court unanimously held:
- Admissibility of Confessional Statement: Under section 135 of the Evidence Act and established authority, a statement alleged to be confessional but denied by the accused is still admissible; its weight is assessed after full trial. Exhibits certified from a duplicate file of a lost original public document satisfy sections 89(e) and 105 of the Evidence Act and are admissible as secondary evidence.
- Signature Comparison: Section 101 of the Evidence Act empowers but does not mandate courts to compare signatures or impressions upon request. In the absence of any party’s application for comparison at trial, the Supreme Court will not direct such a process on appeal.
- Defence of Alibi: A properly raised alibi must set out specific particulars—place, date, time and identity of persons present—to enable police investigation. An alibi mentioned vaguely (e.g. “I was in Lagos”) without particulars is not worthy of investigation and fails to displace identification evidence at trial.
- Grounds of Appeal & Jurisdiction: Grounds of appeal must challenge the decision appealed against and be competently formulated; omnibus or civil‐style grounds are incompetent. The Supreme Court’s jurisdiction is confined to issues arising from the impugned Court of Appeal decision, not to errors at trial.
Court Findings
The Supreme Court reviewed the record and found:
- The trial judge correctly admitted Exhibit A when the accused denied it and properly assessed its weight.
- The certified photostat of Exhibit A qualified as secondary evidence of a public document under sections 87, 89(e) and 105 of the Evidence Act given the loss of the original file.
- No request for signature comparison was made at trial; thus no discretionary order was required.
- Victim‐witness testimony established the appellant’s identity at a well‐illuminated location despite his mask and supported all elements of armed robbery.
- The appellant’s alibi lacked specificity and was raised too late, depriving police of any avenue for verification.
- Several grounds and issues of appeal were struck out as incompetent, and the remaining issues were resolved against the appellant.
Conclusion
The appeal was dismissed. The Supreme Court affirmed both the Court of Appeal’s and the trial court’s convictions and death sentences. The prosecution had proved all ingredients of conspiracy and armed robbery beyond reasonable doubt, and the appellant’s procedural and substantive challenges failed.
Significance
This decision underscores the strict requirements for raising and proving alibi, the admissibility of certified secondary evidence of lost public documents, and the necessity of precise, competent grounds and issues on appeal. It reaffirms that appellate courts will not entertain challenges outside their jurisdiction or a party’s properly framed pleadings. The case provides authoritative guidance on handling alleged confessional statements, signature comparison requests, and the formulation of criminal appeal issues.
