In South Africa, there is no regulatory body regulating polygraph and voices stress analysis tests, nor have the courts in both the criminal, civil and labour arena, set guidelines as to when the polygraph will be acceptable in a court as evidence, on its own. It was held that our labour court and the CCMA do not accept polygraph tests as reliable and admissible without some requirements being met. Firstly, the courts question the reliability of the results in relation to the person administering the test and secondly the reliability of the result itself, being indicative of deception only, not of guilt. The person who administers the test, the polygraph examiner, testifies as an expert in the court or CCMA case and may be an expert in handling the equipment, but is, in most instances, neither a medical doctor nor a psychologist. It has been established that the accuracy of the test also relies on the experience and expertise of the examiner.
