Nine Defendants, One Untouched Finding: Why Silence on Appeal Can Be Fatal: Abdullahi v. State [2026] 11 NWLR (Pt. 2052) 499
Nine Defendants, One Untouched Finding: Why Silence on Appeal Can Be Fatal
Abdullahi v. State [2026] 11 NWLR (Pt. 2052) 499 — Supreme Court of Nigeria
Sometimes a criminal appeal is lost not in the courtroom argument itself, but in what the appellant's lawyers never bothered to challenge. Abdullahi v. State is a case about a gang robbery, a chain of six mutually corroborating confessions — and a procedural trap that swallowed the appellant's case before the Supreme Court even got to the merits: he had never actually appealed against the specific factual finding that convicted him.
The Facts
On 6 May 2015, a man was robbed of a Samsung Galaxy phone, a Honda Odyssey, and other property. Nine people were eventually arraigned at the High Court of Kwara State for conspiracy to commit armed robbery and armed robbery itself; Rafiu Abdullahi was the sixth accused. He pleaded not guilty.
At trial, the victim described the robbery in detail, and the investigating police officer explained how the stolen Samsung phone was traced back to the ninth accused, whose cooperation then led police to the rest of the group, Abdullahi included. Abdullahi's own extra-judicial statement was tendered as evidence after a trial-within-trial confirmed it had been made voluntarily; in it, he admitted not only to this robbery but to having taken part in others before it. On top of that, six separate confessional statements from his co-accused each independently named Abdullahi as a participant in both the conspiracy and the robbery itself.
The trial court found the prosecution's witnesses credible, rejected Abdullahi's denial and his late attempt to claim he was elsewhere at the time, and made a specific finding of fact that he had participated in the armed robbery. He was convicted and sentenced to death. The Court of Appeal affirmed everything. Abdullahi then took his case to the Supreme Court.
The Journey Through the Courts
Before the apex court, Abdullahi's lawyers argued that the prosecution had never truly proved his participation, that his confession was unreliable and effectively the only evidence against him, that he had testified — without being contradicted — that he had never even been to Ilorin, that no independent evidence tied him to any weapon, that the victim never identified him personally, and that the confessional statements were riddled with contradictions.
The Court's Reasoning
A finding you never appealed is a finding you're stuck with. This was the decisive point in the whole case. The trial court had made a specific, standalone finding of fact that Abdullahi participated in the armed robbery. Nowhere in Abdullahi's grounds of appeal to the Court of Appeal, or in his appeal to the Supreme Court, had he actually challenged that specific finding as a distinct ground. The Supreme Court restated a firm rule of appellate practice: once a party fails to appeal a specific finding, the law treats that finding as settled and conclusive against him — and the party cannot then turn around and argue against the conclusion that logically follows from it. An appeal against only the outcome, without challenging the underlying finding that produced it, simply isn't a valid appeal at all.
A general "omnibus" ground of appeal won't rescue a specific factual finding. Related to the point above, the Court explained that where a trial court has made a finding on a specific issue, a party wishing to contest it must raise that finding as its own distinct ground of appeal — it cannot be swept in under a generic, catch-all ground. Abdullahi's broad complaints about the overall correctness of the judgment could not substitute for a targeted challenge to the specific finding that he took part in the robbery.
You can't just ask an appellate court whether the judgment "was right." The Court also made a broader point about how appeals must be framed. Every judgment carries a legal presumption of correctness. An appeal exists to displace that presumption, which means an issue for determination has to argue that the judgment was wrong, and why — not simply invite the appellate court to consider whether it was correct. Abdullahi's framing came uncomfortably close to the latter.
On the merits, the confessions did the heavy lifting anyway. Even setting the procedural point aside, the Court walked through why the conviction was sound. A voluntary confession that is clear and leaves no real doubt about the maker's guilt can support a conviction on its own; here, it was reinforced by the victim's account, the investigating officer's testimony about the phone that led back to the group, and — critically — the confessional statements of six separate co-accused persons, each independently describing Abdullahi's role. Ordinarily, one co-accused's confession isn't evidence against another. But where the charge is conspiracy, the law treats a co-accused's account of the group's shared agreement and joint actions as relevant evidence of that very conspiracy against every member of it. Read together with section 8 of the Evidence Act, which allows the words and acts of one conspirator, done in furtherance of the common plan, to be used as proof of the conspiracy against all who are believed to be part of it, this web of mutually reinforcing statements gave the trial court more than enough to convict.
Proving armed robbery doesn't require tying each defendant personally to the weapon. The Court also reaffirmed that once it's shown a robbery occurred, that it was carried out with arms, and that the accused took part in it, it doesn't matter which specific participant was holding the weapon — the offence is made out against all who participated, so long as at least one of them was armed during the robbery.
Two courts agreeing leaves very little room to argue. Finally, the Court underlined its long-standing caution about disturbing concurrent findings of fact from a trial court and the Court of Appeal. An appellant in that position carries the burden of showing the findings were perverse or contrary to law in a way that caused a miscarriage of justice — and Abdullahi's five grounds of appeal did not meet that bar.
The Verdict
The Supreme Court unanimously dismissed the appeal, affirming Abdullahi's conviction and death sentence for conspiracy to commit armed robbery and armed robbery.
Key Takeaways
- If you want to challenge a specific factual finding on appeal, you must say so directly and specifically — a general or omnibus ground of appeal will not do the job.
- A finding of fact left unchallenged becomes binding. You cannot later argue against a conclusion that flows logically from a finding you never appealed.
- Appeals must argue that a judgment is wrong, not merely question whether it was right. Every judgment starts with a presumption of correctness that the appellant carries the burden of displacing.
- In a conspiracy charge, a co-accused's confession about the group's shared plan can be used as evidence against every member of that conspiracy — even though, outside a conspiracy charge, one person's confession normally can't be used against another.
- A voluntary, clear confession can support a conviction alone, but courts still look for supporting detail where it's available — and multiple independent confessions pointing the same way make for a very hard case to overturn.
- Armed robbery doesn't require every participant to be personally linked to the weapon — only that a robbery took place, that it was armed, and that the accused took part in it.
