New Delhi: The Supreme Court on Thursday issued notice to Solicitor-General G.E. Vahanvati for his assistance in a batch of petitions challenging the use of narco analysis, brain mapping and lie detector tests during police investigation.

A three-Judge Bench of Chief Justice K.G. Balakrishnan, Justice R.V. Raveendran and Justice J.M. Panchal issued the notice in the petitions questioning the methods adopted by the police against the wishes of the accused and seeking framing of guidelines in this regard.

The petitioners had argued that courts could not direct the prosecution to hold narco analysis, brain mapping and lie detector tests on the accused against their willingness as it would be violative of Article 20 (3) of the Constitution (no person accused of any offence shall be compelled to be a witness against himself).
