analysis. In the absence of any forwarding note or requisition, it is not explained as to how the Magistrate forwarded a sample bottle to the chemical examiner as per his covering letter dated 19.8.1997 referred to in Ext.P4 certificate. Even the office copy of the covering letter has not been produced. The thondi section clerk who was the custodian of the properties before the Magistrate, was not examined to prove matters such as the date of receipt of the property before the Magistrate, the condition in which those properties were received in court including the fact whether a sample bottle was received and if so, whether the seals if any on such bottle were in tact, the date of despatch of the sample to the chemical examiner and the nature of the custody of the sample bottle until then. The prosecution can succeed in securing a conviction against the appellant only if it is shown that the sample which was subjected to chemical analysis as evidenced by Ext.P4 certificate was the very same sample which was drawn from the bulk quantity of contraband liquor allegedly held by the accused and which after change of hands, eventually reached the hands of the chemical examiner.”
