“Ext.P5 is a copy of the Forwarding Note submitted before the court for sending sample for subjecting it to chemical analysis. A specific space is provided in the Forwarding Note for affixing the sample seal. No such sample seal was affixed on Ext.P5. Whether the sample seal was affixed on the original of Ext.P5 sent to the Chemical Examiner? Normally, if the sample seal is not appearing in the copy of the Forwarding Note, in this case it is Ext.P5, it has to be presumed that such sample seal was not affixed on the original Forwarding Note unless proved otherwise. A copy of the Forwarding Note is kept in the office of the court for serving certain purposes. The purposes are evidence from the contents of the form of the Forwarding Note itself. They include the quantity and description of the sample drawn from the bulk of the contraband, the details of the case and the space for providing the sample impression of the seal affixed on the sample taken from the bulk of the contraband. Therefore, as already stated, the absence of sample seal in the space provided in the copy of the Forwarding Note. Is sufficient reason for presuming that the sample seal is not provided in the original Forwarding Note. Of course, this is only a rebuttable presumption. In the case on hand, such presumption has not been rebutted by the prosecution.”
