The use of  such evidence is excluded .....on grounds of  its barbarism,its illegality and its inhumanity. The law will not lend it's support  to the sue of torture for any purpose whatsoever. It has no place in the defence of freedom and democracy,whose very existence  depends on the denial of the use of such methods to the executive.
