This question came up before the Supreme Court of India in Selvi vs State of Karnataka (2010).Many from the scientific community assert that the lie-detector test is a big lie; that it is pseudo-science. And the media will condemn the accused. The court, by a detailed judgment, after examining https://www.chinaembroiderymachine.net/ authorities from the world over held: "The use of narco-analysis, brain-mapping and polygraph tests on accused, suspects and witnesses without their consent is unconstitutional and violation of the ‘right to privacy’. The police there use lie-detector tests extensively as an intimidatory tool to extract confession.All lie-detector tests are invasive. At the same time, many innocent individuals passionate to establish their innocence fail the test due to the fear that the findings might possibly go wrong.Surprisingly, in spite of this knowledge, the media in India considers it sensational if someone is about to undergo a lie-detector test.
If the accused volunteers for a lie detector test, s/he should be given access to a lawyer and the physical, emotional and legal implication of such a test should be explained to him/her by the police and his/her lawyer.The belief underlying the use of polygraph is that deceptive or untruthful answers will produce physiological responses that can be differentiated from those associated with non-deceptive or truthful answers.The actual recording of the lie-detector test shall be done by an independent agency (such as a hospital) and conducted in the presence of a lawyer.
The subject is then exposed to external stimuli like sound and visuals relevant to the facts being investigated. The subject would be thrown into a raging river — if she floated, she undoubtedly was a witch and stoning could follow.In the US, there is little scope for the use of third degree methods to extract a confession because of the "Miranda principle". But, ultimately, the polygraph analysis is like any opinion, say that of a handwriting expert.During the hearing before the magistrate, the person alleged to have agreed should be duly represented by a lawyer. Shashi Tharoor, in connection with the death of his wife Sunanda Pushkar in January last year is facing the threat of the lie-detector test. If she sank, no scope for further questions.
