HABIBU V. STATE (2026)

Background

This appeal concerned the conviction of Ibrahim Habibu for criminal conspiracy under section 97 of the Penal Code and culpable homicide punishable with death under section 221(b) of the Penal Code applicable in Kano State. The appellant was tried alongside his nephew and his brother before the High Court of Kano State. The prosecution alleged that the appellant and his co-accused conspired to kill the appellant’s 85-year-old father, Mallam Haladu Adamu.

The prosecution’s case arose from the sale of two bulls which the deceased had placed in the appellant’s care. The appellant allegedly sold the bulls and distributed part of the proceeds to the other accused persons, but falsely told the deceased that the animals had been stolen. After the deceased discovered the truth and threatened to employ a traditional healer against the person responsible, the appellant sought forgiveness. Although the deceased accepted his apology on the condition that certain expenses be refunded, he was attacked in his home that same night while asleep. A witness, Sani Usman, heard the deceased shouting and went to the house, but the attackers escaped. The deceased was taken to hospital and died six days later. Medical evidence attributed the death to suffocation and strangulation.

During police investigation, the appellant’s statements, in English and Hausa, were admitted as exhibits 3, 3A and 7. The prosecution also relied on circumstantial evidence and medical reports. The appellant did not object when the statements were tendered and did not cross-examine the relevant witnesses on their admissibility or contents. He later denied making the statements voluntarily, alleging duress, and raised an alibi for the first time during his defence. The High Court convicted him and imposed the death sentence. The Court of Appeal, Kaduna Division, affirmed that decision.

Issues

1. Whether the Court of Appeal was right to affirm the conviction and sentence based substantially on the appellant’s confessional statements.
2. Whether the prosecution proved the appellant’s guilt of conspiracy and culpable homicide beyond reasonable doubt.
3. Whether the statements were inadmissible for want of certification, and whether the trial court ought to have conducted a trial-within-trial.
4. Whether the Supreme Court should interfere with the concurrent factual findings of the High Court and Court of Appeal.

Ratio Decidendi

The Supreme Court unanimously dismissed the appeal. It held that culpable homicide punishable with death requires proof beyond reasonable doubt that the deceased died, that the death resulted from the act of the accused, and that the act was intentional, with knowledge that death or grievous bodily harm was a possible consequence.

The Court reaffirmed that criminal guilt may be proved in three principal ways: by a voluntary confessional statement, by circumstantial evidence, or by the evidence of an eyewitness. Any one of these methods may be sufficient to sustain a conviction where the evidence is credible and satisfies the required standard.

Under section 28 of the Evidence Act 2011, a voluntary confession is admissible and may, standing alone, support a conviction. A later retraction or denial does not automatically make the statement inadmissible. The proper question is the weight and credibility to be attached to the statement. Since the appellant raised no objection when the statements were tendered, the trial court was not required to conduct a trial-within-trial. Such a procedure is designed to determine voluntariness where voluntariness is challenged at the stage of tendering the statement; it is not an automatic requirement in every criminal trial.

The Court also held that the original of a public document is primary evidence and does not require certification before admission. Certification is relevant where a party seeks to rely on a certified copy as secondary evidence in the absence of the original. The appellant’s argument that the confessional statements ought to have been certified was therefore misconceived.

Court Findings

The Court found that the prosecution discharged its burden under section 135 of the Evidence Act 2011 and section 36(5) of the Constitution. Proof beyond reasonable doubt does not mean proof beyond every conceivable doubt; it requires compelling and conclusive evidence producing a high degree of probability of guilt. Once the prosecution establishes the offence to that standard, the evidential burden may shift to the defendant to raise a credible reasonable doubt.

The medical reports established the death and its cause. The appellant’s confessional statements supplied evidence of his participation and intention, while the surrounding circumstances supported the prosecution’s case. The Court applied the principle that a person is presumed to intend the natural and probable consequences of his acts. The statements also disclosed an agreement between the appellant and his co-accused, which was sufficient to establish conspiracy. Although conspiracy is commonly proved by inference from surrounding facts rather than direct evidence of an agreement, the confession in this case provided direct support for the finding.

The alibi was rejected because it was raised belatedly, during the appellant’s defence, and lacked the particulars necessary to make it verifiable. The Court emphasized that an accused does not bear the ultimate burden of proving an alibi, but an alibi must be raised at the earliest opportunity and with sufficient detail. The police have no duty to investigate or disprove an alibi that is vague, worthless, or introduced as an afterthought.

Finally, the Supreme Court held that there was no special or exceptional circumstance justifying interference with the concurrent findings of the two lower courts. Those findings were neither perverse nor shown to have occasioned a miscarriage of justice.

Conclusion

The appeal was dismissed. The Supreme Court affirmed the judgment of the Court of Appeal, which had affirmed the High Court’s conviction of Ibrahim Habibu for criminal conspiracy and culpable homicide punishable with death, together with the sentence of death by hanging.

Significance

Habibu v. State is significant for its restatement of Nigerian criminal evidence principles. It confirms the potentially decisive character of a voluntary confessional statement, clarifies that retraction affects weight rather than admissibility, and explains when a trial-within-trial is necessary. It also distinguishes primary originals from secondary copies of public documents and reinforces the limited scope of Supreme Court intervention in concurrent findings of fact. The decision further illustrates that the constitutional presumption of innocence and the prosecution’s burden of proof remain fundamental, but do not prevent conviction where a credible confession, supported by surrounding circumstances, establishes guilt beyond reasonable doubt.
