There Is No Law In Nigeria That Supports Use Of Polygraph Test – Says SAN Defending Chrisland Schools Supervisor Against Child Defilement

Did a supervisor with Chrisland Schools in Lekki, Lagos, Adegboyega Adenekan, accused of defiling a 35-month-old pupil, lie about his relationship with the girl? Yes, says a report of the polygraph test conducted on him by an expert, Mr Falola Adebayo.

A polygraph machine is used to determine whether a person is deceptive or lying.

Justice Sybil Nwaka of the Ikeja Domestic Violence and Sexual Offences Court will on October 10 rule on the admissibility of the report.

Adenekan’s counsel Olatunde Adejuyigbe (SAN) objected to the admissibility of the report when the prosecutor, Babajide Boye, sought to tender it in evidence.

Justice Nwaka gave the lawyers up till August 13 to file their written submissions on the report.

Adebayo, who works with Halogen Security Company Limited, Ikeja, said polygraph test was used to investigate theft, burglary, infidelity and sexual harassment, among others.

Adebayo, who claimed to have over 15 years experience in polygraphy examination, said the report of Adenekan’s test showed that he scored -9, indicating that he was deceptive and was not telling the truth about the alleged defilement of the girl referred to as Child X.

Led in evidence by Boye, Adebayo, a retired Nigerian Army Intelligence and Forensic expert, who was trained at the American Institute of Polygraph Examination, said the united accuracy of a polygraph test was 99.9 per cent, adding that the remaining “.01 per cent is just a give-away”.

Adebayo said 10 questions, including relevant and non-relevant ones, were set for Adenekan.

Before the test was conducted, Adenekan, he said, filled a consent form, adding that two other teachers from the school, and the child’s mother also filled the form for the same purpose.

“The defendant sat down and said he was prepared to undergo the test as he needed to exonerate himself. He was asked if he is suffering from hypertension, diabetics and he said ‘No’.

“I asked for his qualification and I explained my qualification to him as to what qualifies me as a polygraph expert.

“I made him touch all the equipment we use and explained their functions to him, including the one that measures breathing, blood pressure, the two fingers to be clipped and I asked him if any of them shocked him and he said ‘No’.”

He said the test would not have been conducted on Adenekan if the subject was hypertensive or diabetic.

When Boye sought to tender the report through the witness, who identified it as the document he signed, Adejuyigbe objected.

The report, Adejuyigbe argued, did not conform with the provisions of the Evidence Act, describing it as an opinion produced by a machine.

The totality of it is inadmissible by the Evidence Act. Nothing in Sections 68 to 76 permit admissibility of an opinion as to whether somebody is lying or not. Also no foreign law can be used to determine the admissibility of the report. The document that the prosecution is seeking to tender is excluded by the Evidence Act,” the SAN argued.

He said the use of polygraph test was not supported by any law in Nigeria, warning that Nigeria should not open its door to opinions generated from a machine.

“We urge the court to reject the polygraph report especially since the defendant has not put his character on the line for examination and because opinion formed by a machine can be manipulated”, he argued.

But Boye insisted that the report is admissible because it is relevant to the case.

The defendant, he said, was not compelled to undergo the test.

“He consented to the examination and even filled the consent form.”

The report, the prosecutor said, did not adjudge the defendant but would assist the court to reach a decision on the matter. [NAN]

  1. You are a stupid lawyer to make such a nasty comment against unprotected child because of money, remember you sin and judgment will follow you to your grave because you offended GOD and he will shot you from through heaven and don’t be surprise .Remember we are talking about a CHILD HERE who has no one to save her in the hand of a scavenger i wish that will happen to your own children for you to test it .
    Almighty GOD will fight for her and you will see all you have made will go in drain

  2. Polygraph machine should not be depended on to either convict or set free the accused. A very good liar will go free but inside of him he knows he is guilty of the offense he is accused of. A case in point is one our friends back in Arkansas when we were still in the university. We were at work (we go to school & work). This guy drank a bottle of beer while at work (and this was in our presence). The manager smelled nit in his breath and when questioned denied he never drank. He was taken to the police station to administer the polygraph test and he passed. We knew he drank a bottle of Budweiser beer because we were there. Since then I never believed never to rely on polygraph test even judges do not admit it in court.
