Editor’s Note: Till recently, the courts had to rely on non-scientific evidences only because of the non-availability of proper technology. Scientific evidences are crucial to the fact finder in order to arrive at the logical consequence in deciding large number of issues brought before him/her. In the present era, they have almost become indispensable to them. However, a key issue which can be encountered by a judge/jury when ever scientific evidence is put before him/them is whether scientific evidence is worth believing or not. This is because due to the subjective nature of tests like narcoanalysis, the foremost criticism levelled against conducting the test is its conclusiveness. Therefore, there is a need for the Central government to make a clear policy stand on narco analysis because what is at stake is India’s commitment to individual freedoms and a clean criminal justice system.
