Forensics in Nigeria: How to Interpret and Challenge Forensic Evidence
In Nigeria’s criminal justice system, forensic evidence plays a central role in establishing guilt or innocence. Judges often attach significant weight to reports such as fingerprints, DNA, ballistics, and autopsy findings, since they appear scientific and objective.
However, forensic evidence is not always perfect. Poor laboratory facilities, weak chain of custody, and human error can compromise its reliability. For any lawyer or law student in Nigeria, understanding how to interpret and challenge forensic evidence is crucial for effective courtroom advocacy.
1. Fingerprint Evidence in Nigeria
Fingerprint analysis is commonly used in robbery, burglary, and homicide cases.
- Challenge: In Oseni v. The State (2012) LPELR-7843 (CA), the Court of Appeal warned that fingerprint evidence must be handled with care. A conviction cannot rest solely on fingerprints unless the prosecution proves proper collection, preservation, and expert analysis.
Key Point: Always question whether the fingerprint was properly lifted, preserved, and compared by a qualified examiner.
2. DNA Evidence: Powerful but Problematic
DNA is persuasive in Nigeria but not without flaws.
- Case Example: In FRN v. Dairo (2015) LPELR-24723 (CA), the court emphasized that scientific evidence like DNA must be subjected to rigorous scrutiny, and the defense has the right to cross-examine the expert.
- Challenge: Limited labs and risk of contamination weaken reliability.
Defense Strategy: Ask whether the DNA lab used internationally recognized standards (ISO/IEC 17025). If not, argue unreliability.
3. Ballistics in Nigerian Courts
Ballistic evidence connects bullets and firearms.
- Case Example: In Oteki v. The State (2014) LPELR-23126 (CA), the Court of Appeal noted that ballistic reports must be corroborated by other evidence before a conviction can stand. This shows that ballistics alone cannot always establish guilt beyond reasonable doubt.
Key Point: Lawyers should check whether the firearm was properly secured in the exhibit register and whether analysis was peer-reviewed.
4. Autopsy Reports in Nigerian Courts
Autopsies (post-mortems) are vital in homicide and suspicious death cases.
- Case Example: In Adamu v. The State (2017) LPELR-42565 (CA), the court stressed that autopsy evidence is crucial in establishing cause of death, but it must be clear, thorough, and presented by a qualified medical expert.
- Case Example: In Akpuenya v. The State (1976) 11 SC 269, the Supreme Court held that medical evidence is not always indispensable if the cause of death can be inferred from other compelling evidence.
Key Point: If the autopsy was conducted by an unqualified person or without toxicology tests, a defense lawyer can challenge its credibility.
Why Challenging Forensic Evidence Matters in Nigeria
Wrongful convictions have occurred in Nigeria due to unquestioned reliance on weak forensic reports. By scrutinizing how evidence was collected, stored, and analyzed, lawyers can protect clients’ rights and strengthen the justice system.
Final Thoughts
Forensic evidence can be powerful, but it is not foolproof—especially in Nigeria, where forensic infrastructure is still developing. Nigerian case law shows that courts demand not just scientific evidence, but credible, reliable, and corroborated scientific evidence. For lawyers and law students, the ability to interpret and challenge forensics is not optional; it is essential.
