Introduction Interrogation techniques play a crucial role in criminal investigations, helping law enforcement officers obtain information and confessions from suspects. However, the legality and ethical considerations surrounding these techniques are of paramount importance, particularly within Nigeria’s legal framework. The Administration of Criminal Justice Act (ACJA) 2015 and various state-level Administration of Criminal Justice Laws (ACJL) regulate criminal procedures, including the interrogation of suspects. This article examines commonly used police interrogation techniques and their legal implications under Nigerian law, particularly regarding the admissibility of confessions, protection against coercion, and the rights of suspects.
- Protection Against Coerced Confessions Many interrogation techniques, such as the Reid Technique, Mr. Big, Maximization, Perpetual Denials, and Rapid Fire Questioning, apply psychological pressure on suspects to elicit confessions. However, Nigerian law prioritizes the voluntariness of confessions:
- Section 29 of the Evidence Act 2011 states that a confession must be voluntary to be admissible in court. If it is obtained through coercion, intimidation, or undue influence, it must be excluded from evidence.
- ACJA 2015 Section 15(4) mandates that confessions be recorded on video or documented in writing in the presence of a legal practitioner to prevent coercion.
These provisions serve to curb the use of manipulative interrogation methods that could lead to false confessions.
- Right to Legal Representation During Interrogation Some interrogation strategies, such as Good Cop/Bad Cop and Informal Questioning, are designed to extract confessions before a suspect seeks legal advice. However, Nigerian law ensures suspects’ rights to legal representation:
- Section 6(2) of ACJA 2015 states that a suspect must be informed of their right to legal representation before interrogation.
- Section 36(6)(c) of the Nigerian Constitution guarantees an accused person’s right to legal counsel.
Failure to comply with these provisions may render any confession obtained inadmissible in court.
- Prohibition of Torture and Psychological Manipulation Certain interrogation methods, including Pride and Ego Down, Loaded Questions, and Repetition, can exert significant psychological distress on suspects. Nigerian law explicitly prohibits any form of coercion during interrogations:
- The Anti-Torture Act 2017 criminalizes the use of mental or psychological pressure, including intimidation and prolonged interrogations.
- Section 8(1) of ACJA 2015 prohibits the use of torture, inhumane, or degrading treatment in criminal investigations.
These legal safeguards are aimed at ensuring interrogations remain ethical and respect human rights.
- Ethical and Non-Coercive Interrogation Techniques The PEACE Model, an ethical interrogation technique that focuses on voluntary disclosure rather than coercion, aligns with Nigeria’s commitment to justice and fairness. The five stages of the PEACE Model—Planning and Preparation, Engage and Explain, Account, Clarification and Challenge, Closure, and Evaluation—comply with Nigeria’s legal standards, promoting interrogations based on dialogue and transparency rather than psychological manipulation.
- Admissibility of Confessions and Improper Interrogation Practices Under Nigerian law, evidence obtained through improper interrogation methods may be deemed inadmissible:
- ACJA Section 14 provides for the exclusion of evidence obtained through oppression or deceit.
- Section 29(2) of the Evidence Act 2011 states that confessions made under duress, threat, or intimidation must be disregarded by the courts.
Techniques such as Mr. Big, Maximization, and Perpetual Denials, which involve deceptive or coercive tactics, may thus lead to confessions that courts may reject.
Conclusion While police interrogation techniques are essential for criminal investigations, Nigerian law places strict limits on their application to prevent rights violations. The ACJA 2015, the Constitution, the Evidence Act 2011, and the Anti-Torture Act 2017 collectively ensure that suspects are protected from coercion and that only voluntary confessions are admissible in court. Law enforcement agencies must align their practices with ethical standards, adopting non-coercive methods such as the PEACE Model to uphold justice and safeguard human rights in Nigeria’s criminal justice system.
