Self-defence in Nigerian criminal law is a doctrine that allows individuals to use reasonable force to protect themselves, others, or their property from imminent harm. This defense, if successfully argued, can exonerate a defendant from criminal liability for actions that would otherwise be deemed illegal. This article provides a detailed examination of self-defence in the Nigerian legal context, including statutory provisions and judicial interpretations.
Statutory Provisions
The principal legal framework for self-defence in Nigeria is found in the Criminal Code Act (applicable in Southern Nigeria) and the Penal Code Act (applicable in Northern Nigeria). These statutes outline the circumstances under which self-defence can be legally justified.
Criminal Code Act (Southern Nigeria)
- Section 286:
- This section provides that a person is justified in using force to defend themselves or another person from unlawful violence or an unlawful threat of violence.
- The force used must be reasonably necessary to prevent or terminate the violence.
- Section 287:
- This section extends the right of self-defence to the protection of property. A person may use force to prevent trespass to property or to eject a trespasser.
- Section 32:
- Self-defence is listed among the general defences that can exonerate a defendant from criminal liability if the force used was reasonably necessary to avert an immediate threat.
Penal Code Act (Northern Nigeria)
- Section 59:
- This section provides that nothing is an offence if it is done in the exercise of the right of private defence.
- Section 60:
- The right of private defence does not extend to inflicting more harm than necessary to prevent the offence.
- Section 61:
- This section stipulates that the right of private defence of the body extends to causing death under certain circumstances, such as in defence against assault causing reasonable apprehension of death or grievous harm.
Judicial Authorities on Self-Defence
Nigerian courts have interpreted and applied these statutory provisions in various cases, elucidating the principles and limitations of self-defence.
Key Cases
- Uguru v. The State (2002) 9 NWLR (Pt. 771) 90:
- The Supreme Court of Nigeria held that for a plea of self-defence to succeed, the defendant must prove that they were in imminent danger of death or serious bodily harm and that the force used was necessary and proportionate to the threat.
- Ahmed v. The State (1999) 7 NWLR (Pt. 612) 641:
- The court emphasized that self-defence requires a reasonable belief of imminent danger. The defendant must demonstrate that they had no alternative means of escape or avoidance of the threat.
- Nwaeze v. The State (1996) 2 NWLR (Pt. 428) 1:
- This case reiterated that self-defence must be immediate and proportionate. Excessive force or preemptive strikes not warranted by the situation would negate the claim of self-defence.
- Igbineweka v. The State (2006) 6 NWLR (Pt. 975) 100:
- The court held that the burden of proof lies on the defendant to show that the harm was necessary to avert an immediate threat. The proportionality of the force used is crucial in determining the validity of the self-defence claim.

Considerations in Self-Defence Claims under Nigerian Criminal Law
- Imminence of Threat:
- In the context of self-defence under Nigerian law, the threat must be immediate, meaning it cannot be a future or speculative harm but must be an actual and present danger. The defendant must show that they were facing a direct and imminent threat at the time of their defensive actions. This immediacy requirement ensures that self-defence is only justified in situations where there is no time to seek help or escape, thereby necessitating the use of force to prevent harm.
- Reasonable Belief:
- For a self-defence claim to be valid under Nigerian law, the defendant must have a reasonable belief that they or another person were in imminent danger. This belief must not only be genuine but also objectively reasonable, meaning that a typical person in the same situation would perceive the threat similarly. The standard ensures that self-defence is based on a realistic assessment of danger, rather than an exaggerated or irrational fear.
- Proportionality of Force:
- The force used in self-defence must be proportional to the threat faced, meaning it should be no more than necessary to repel the immediate danger. If the force applied exceeds what is reasonably required to neutralize the threat, it is deemed excessive and can invalidate the self-defence claim. This proportionality requirement ensures that the defensive actions are justified and not used as a pretext for unnecessary aggression.
- Necessity:
- The use of force in self-defence must be necessary to avert the threat, implying that it should be the last resort to prevent harm. If reasonable alternatives were available, such as retreating or calling for help, and these options could have effectively neutralized the danger, then the use of force may not be considered justified. This necessity requirement ensures that force is only employed when absolutely indispensable for protection.
- Duty to Retreat:
- Nigerian law does not impose a strict duty to retreat before using force in self-defence. However, if it can be shown that retreating or avoiding the confrontation was a safe and viable option, the necessity of using force may be questioned. This means that while the law allows for standing one’s ground, the reasonableness and necessity of the defensive action are still scrutinized, potentially affecting the validity of the self-defence claim if less violent alternatives were available.
Conclusion on Self-Defence under Nigerian Criminal Law
Self-defence in Nigerian criminal law is a nuanced doctrine that balances the right to protect oneself and others against the need to prevent excessive or unwarranted use of force. The statutory provisions in the Criminal Code Act and the Penal Code Act provide the legal foundation for self-defence, while judicial interpretations offer clarity on its application. Individuals claiming self-defence must demonstrate that their actions were in response to an immediate threat, that their belief in the danger was reasonable, and that the force used was both necessary and proportionate. Understanding these elements is crucial for navigating self-defence claims in Nigeria’s legal system.
