is not the seal affixed by him at the time of detection. This means that there was clear tampering. The extract of the property register proved in evidence does not show that any sample was produced in Court. PW3 stated that he had filed a requisition in Court for taking sample. Such a requisition is not seen produced or proved. It is not known what seal was affixed on the sample, whoever collected it. This Court has settled that the copy of the forwarding note or requisition must be proved in evidence, and it must contain the specimen of the seal affixed on the sample. No such specimen is produced in Court. Thus, there is nothing to identify the sample sent for analysis, as the sample collected from the possession of the accused. In such a situation, the report of analysis will not bind the accused, and there is nothing to show that the liquid involved in this case was identified as arrack, as the prosecution would allege. This itself is a ground for acquittal. Even otherwise, I find that the whole prosecution is vitiated because, the essential function of detection was made by an incompetent officer.
