INTRODUCTION

Oforlete v. The State is a landmark case in Nigerian criminal system that provides a thorough  interpretation of the principle of causation.1 Decided by a five-judge panel of the Supreme Court  in 2000, the case underscores the burden that is placed on the prosecution to prove that the  actions of the accused directly caused the death of the victim. 

This ruling is especially significant in cases where a substantial amount of time has passed  between the alleged act and the death, making it harder to establish a clear causal link. The case  reinforces that without proof of causation, a murder conviction cannot stand. 

The principle of causation is a concept that connects mens rea and actus reus in a way that but  for its presence, no crime is committed. An accused with the necessary mens rea can only be  liable if it can be shown that it was his conduct that caused the prohibited act, that is the actus  reus. It is often the case especially in homicide cases that the injury inflicted by the accused on  the deceased is aggravated by another cause that it becomes unreasonable to hold him  responsible for the subsequent death of the victim. In this situation, the chain of causation is  broken and any resultant death is attributed to a new cause. 

BACKGROUND

The appellant, Patrick Oforlete, was charged with the offence of murder contrary to section  319(1) of the Criminal Code. At the trial, which commenced at the Orlu High Court, the  appellant pleaded not guilty to the charge after it was read and explained to him. Thereafter both  the prosecution and the defense called witnesses in support of their respective cases and later  addressed the trial court before the case was adjourned for judgment. On the 29th of January,  1993, the learned trial Judge, Onunuju J. delivered his judgment in which he found the appellant  not guilty of murder but guilty of manslaughter and sentenced him to a term of five years  imprisonment. 

The appellant, dissatisfied with the judgement appealed to the Court of Appeal against  conviction and sentence. The Court of Appeal heard the appeal, dismissed it as being without merit and affirmed the decision of the trial court. The appellant, still not satisfied, appealed to the  Supreme Court against conviction and sentence on four grounds and this was where a sound  judgment was delivered. 

FACTS OF THE CASE

The appellant got into a fight with his brother, the deceased, during which he hit a kitchen stool  on the head of the deceased. No complication arose until three months later when the head of the  deceased got swollen. He was rushed to the hospital where the doctor examined his head and  found a blood clot on the head which was infected. He further carried out an x-ray of the skull  but found no visible injury to the bone. The deceased left the hospital but was admitted five days  later in a semi conscious state with serious blood infection from the head injury. There was  improvement for 3 days but his condition got worst and he was then moved to a psychiatrist  hospital where he died. 

A different doctor who conducted the post mortem found a fresh looking swelling on the left side  of parietal area of his skull and a spontaneously closed skull fracture. The doctor further opined  that the deceased must have died as a result of traumatic head injury leading to infected scalp and  that the head injury could have been acquired at any time when that part of the head came into  contact with a hard object.

LEGAL ISSUES 

The primary issue which the court was burdened with to answer was whether the appellant was  rightly convicted and sentenced by the lower courts based on the medical evidences. 

The secondary issues that were brought before the court includes: 

  1. Whether trial of the appellant which led to his conviction and sentence was valid in law.
  2. Whether, the appellant’s defense was adequately considered.

ARGUMENTS

The petitioners argued that the two medical reports given by different doctors at different times  showed significant discrepancies. The first doctor, who treated the deceased while he was still  alive, found no skull fractures, only a blood clot. In contrast, the second doctor, who conducted  the post-mortem, reported a fresh-looking swelling and a skull fracture. Based on this, the petitioners questioned whether the actions of the accused truly caused the death of the deceased  or whether another intervening factor was responsible. They argued that, given the time lapse  between the altercation and the medical examinations, it was unclear what exactly led to the  death. Since the prosecution failed to provide clear and credible evidence directly linking the  actions of the accused to the fatal outcome, they urged the court to resolve the doubt in favor of  the accused and acquit him.

The respondents argued that the medical evidences of the two doctors confirmed the fact that the  deceased’s death was caused by injury on the head inflicted by the accused. They stated that at  the time the injury was inflicted the skull of the deceased was fractured though it was regarded  not serious. The first doctor saw the swelling as well as the second doctor. Hence, it is non  contradictory that the accused inflicted the injury which broke the skull of the deceased resulting  in his death. 

ANALYSIS OF THE COURT

Kalgo, J.S.C, who delivered the lead judgment, noted the inconsistency between the medical  reports. The first doctor, who examined the deceased while alive, found no visible skull injury,  only a blood clot. However, the second doctor, during the post-mortem, observed a fresh  swelling and a skull fracture. Justice Kalgo emphasized that these two findings were in clear  conflict and should not have been accepted by the trial court or affirmed by the Court of Appeal.  This discrepancy raised serious doubt about whether the injury inflicted by the appellant striking  the deceased with a kitchen stool actually caused the death, or whether it was the result of the  later-identified fresh swelling. The court resolved this doubt in favor of the appellant and  overturned the conviction.

In support of this position, the court cited R v. Oledima, where the accused administered an  injection that may have caused the deceased’s death. However, since the prosecution failed to  establish a direct causal link between the injection and the death, the accused was acquitted.2 Similarly, in Giremabe v. Bornu,3the court reached the same conclusion due to lack of causal  evidence.

The court also found that the prosecution failed to prove that the appellant’s act accelerated the  deceased’s death. In contrast, the court referred to Effanga v. The State, where the accused was  held liable because the injury he inflicted on the deceased led directly to septicemia and death.4

Ayoola, J.S.C, in his concurring opinion, stressed that in homicide cases, the cause of death  must be clearly established and proven beyond reasonable doubt. If the cause is uncertain, the  inquiry should not proceed. Once established, it must then be linked to the act of the accused or  omission through evidence.

From the above, it is clear that proving the cause of death is fundamental before attributing  liability. In the present case, the act alleged to have caused the death was a head injury from a  hard object. However, conflicting medical evidence left the actual cause of death uncertain. The  contradictions, coupled with the significant time lapse between the injury and the first treatment,  weakened the causal link between the act of the appellant and the death of the deceased. The  uncertainty created reasonable doubt, making it unsafe to convict.

To contrast, the case of R v. Malcherek was cited. In that case, the accused stabbed his wife,  who was placed on life support after her heart stopped. When doctors later confirmed brain death  and turned off the ventilator, the accused argued that the action of the doctor and not his caused  the death. The court rejected this defense, holding that the original stab wound remained the  operative cause of death.5 Unlike in this present case, there was no intervening cause that created  reasonable doubt.

DECISION OF THE COURT

Kalgo J.S.C who delivered the leading judgment stated that to sustain a conviction for the  offence of manslaughter, which the accused was convicted for in the lower courts, it must be  established beyond reasonable doubt, that it was the act of the accused that directly caused the  death of the deceased and since the prosecution could not prove that beyond reasonable, the conviction of manslaughter was set aside by the judge. 

Considering the act of the appellant, the judge held that the act of hitting a hard object on the  head of another is an unlawful act constituting an offence under section 355 of the Criminal  Code.6 Hence, the appellant was convicted of the offence of assault occasioning bodily harm contrary to the provisions of section 355 of the Criminal Code and sentenced to 1 year  imprisonment with hard labour.7

SIGNIFICANCE

This case is particularly significant because it underscores the level of diligence required by the  prosecution to secure a conviction in a murder charge. It lays a solid foundation for the principle  of causation in Nigerian criminal system, reinforcing that the onus is always on the prosecution to prove, beyond reasonable doubt, a direct causal link between the act of the accused and the  death of the deceased.

Given that murder is a capital offence, punishable by death, the law sets a high evidentiary  threshold. As illustrated in Mbang v. The State,8the burden of proof must be met strictly and  convincingly. This case reinforces that principle and sets a precedent for future prosecutions.

CONCLUSION 

This case focuses on the principle of causation and its critical role in criminal prosecutions. In  this instance, the prosecution failed to establish a clear, credible link between the act of the  accused and the death of the deceased. The contradictory medical evidence and the time lapse  between the incident and treatment left the cause of death uncertain, relying instead on  assumptions.

The court emphasized that judgments cannot be based on speculation, but must be founded on  clear, consistent, and credible evidence. Consequently, the Supreme Court set aside the  conviction for manslaughter. However, since it was clearly established that the accused struck  the deceased with a kitchen stool, the court found him guilty of assault occasioning bodily harm,  contrary to section 355 of the Criminal Code.9

This case is of great importance to legal practitioners, especially prosecutors, as it highlights the  rigorous standards of proof required in homicide cases. I agree with the court’s judgment, as it was rightly based on a thorough analysis of the evidence and adherence to legal principles,  particularly the doctrine of causation.
