(3) Narco   Analysis   Test:­  It   is   conducted   by   injecting   3   grams   of  sodium   pentathol    dissolved  in   3000   ml   of  distilled   water   and  above  solution is administered intravenously along with 10% of destrose over a  period of three hours with the help of anesthetist. Obviously this test has  R/CR.MA/5391/2018 JUDGMENT some invasion on the body. The rate of administration is so controlled to  drive  the suspect slowly into the state of hypnotic trace. The ECG and  blood   pressure   are   monitored   continuously   throughout   the   testing  procedure.   The   revelations   made   during   the   hypnotic   trance   are  recorded both in the video and audio cassettes. The entire conduct of the  procedure is video graphed. The questions are designed carefully and are  repeated persistently in order to reduce the ambiguities during the drug  interrogation. After the Narco examination is over the suspect is made to  relax for 2­3 hours. The report prepared by the experts is useful in the  process of collecting the evidence.

19. Report of the Narco Analysis Test:­ Taking   into   consideration,   aforesaid   case   papers,   interrogation   of  Investigating Officer and the suspect and the results of narco­test, it is   found that,  (1) Looking to the geographical condition of the school room as   shown by Mayuri, it appears that the glass of window of the room is   found broken which opens up in the school lobby where the movement   of   student   is   found   during   recess   time.   Under   such   geographical   condition,   the   possibility   of   calling   other   girls   into   class   room   accompanying Mayuri, and committing the ill act appears the least. 

Conclusion:­ During   the   Narco   Analysis   of   Sunilkumar   Virjibhai   Damor   in  respect of the evil act committed with Mayuri, it was found that   he has not committed the evil act with Mayuri or any other girl   of the school. If the child plays mischief, he used to beat lightly   on the back of the child. 

Further investigation be conducted after relating information   received during Narco Analysis with other evidences/witnesses. 

20. Thus,   the   reports   of   the   three   tests   prima­facie   create   a   grave  doubt   as   regards   the   involvement   of   the   applicant   -   accused   in   the  alleged crime. In fact, the report of the Narco Analysis test as well as the  R/CR.MA/5391/2018 JUDGMENT report of the Brain Mapping test gives a clean­chit to the accused. The  two reports state in clear terms that the accused is innocent.

21. The   deception   detection   tests   (DDT)   such   as   polygraph,   narco­ analysis   and   brain­mapping   have   important   clinical,   scientific,   ethical  and   legal   implications.   The   DDTs   are   useful   to   know   the   concealed  information related to the crime. This information, which is known only  to the self, is sometimes crucial for the criminal investigation. The DDTs  have   been   used   widely   by   the   investigating   agencies.   However,   the  investigating   agencies   know   that   the   extracted   information   cannot   be  used as evidence during the trial stage. They have contested that it is  safer than the 'third degree methods' used by some investigators. Here,  the claim is that, by using these so called, "scientific procedures" in fact­  finding,   it   will   directly   help   the   investigating   agencies   to   gather  evidences, and thereby increase the rate of conviction of the guilty and  the rate of acquittal  of the  innocent. However, the  Supreme Court in  Selvi Case (supra) has held that an accused cannot be subjected to such  tests without his consent.
