A polygraph test is used to verify a person’s truthfulness.

Consent must be obtained in writing from the person who is to undergo a polygraph examination and this provision should be included in the contract of employment. You cannot compel a person to undergo a polygraph examination.

Polygraph testing on its own is inherently unreliable and should be viewed with great circumspection.

Polygraph test results should be used only in support of other evidence. It is inconclusive in the absence of any other evidence. The test merely indicates probability and cannot show guilt beyond a reasonable doubt.

It is the duty of Commissioners employed by the CCMA or a Bargaining Council to determine the admissibility or reliability of the evidence.
