register has been produced before the trial Court. It is also not coming forth as to why the sample of contraband item, which was dispatched by the Police Station on 12.01.2011, took seven days to reach Jammu from the Police Station Udhampur. This casts serious doubt on the prosecution story. In the light of the evidence on record, it is very difficult to say that the sample, that was allegedly seized from the respondent and the sample which was actually tested by the FSL Jammu, was the same sample. The safe custody of the contraband item from the date it is seized till it is put to chemical examination by the FSL is sine qua non for connecting the person from whom the alleged contraband is seized with the commission of offence under Section 8/15 of the NDPS Act. The learned trial Court taking note of this aspect has rightly concluded that the prosecution has failed to prove the case against the respondent beyond any reasonable doubt.
