POLYGRAPHS ALLOWED – TRUE OR FALSE?

POLYGRAPHS ALLOWED – TRUE OR FALSE?

27 June 2017

A polygraph (commonly referred to as a lie-detector) is a device used for verifying the truthfulness (or lack thereof) of a person’s statements. Currently there is no legislation regulating the use of the polygraph and therefore nothing prohibiting or preventing the submission of polygraph results at disciplinary hearings or similar inquiries. However, this does not mean that polygraphs may be used willy-nilly or relied upon exclusively.

Polygraph results have been submitted and acknowledged in a number of CCMA cases recently. The science behind the polygraph process is (by this time) well understood and accepted. It is not for a CCMA commissioner to decide whether or not the polygraph results should be admissible but rather how much weight these results should be ascribed.
