petitioner, which is stated hereunder. Ext.P9 is the copy of the forwarding note whereby the sample was forwarded to the chemical examiner. The copy of the forwarding note is silent with regard to the name of the person with whom the sample was sent for analysis. Ext.P4 Certificate of chemical analysis would show that the sample was received in the laboratory through the Excise Guard Sri.Dinesan on 2.8.2007. It is not discernible as to why the space meant for writing the name of the Excise Guard/Preventive Officer, with whom the sample was sent, remained vacant in Ext.P9 copy of the forwarding note. This would give an indication that even at the time when the learned Magistrate put the initial in the copy of the forwarding note, it was not decided as to with whom the sample had to be sent to the laboratory for analysis. It is also not discernible from Ext. P9 as to when the learned Magistrate put the initial in the forwarding note. The learned Magistrate ought to have written the date on which the initial was made, which is normally expected in a case like this. However, since the date was not written by the learned Magistrate when the initial was made, it is not clear from Ext.P9 as to how many days before the despatch of the sample, the learned Magistrate put the initial in Ext.P9. This becomes relevant, particularly when the space meant for writing the name of the Excise Guard/Preventive Officer with whom the sample was sent, remained vacant in Ext.P9 copy of the forwarding note. In such a situation, it was imperative for the prosecution to examine the thondy clerk of the court or the Excise Guard concerned to prove the tamper-proof despatch of the sample to the laboratory. However, neither the thondy clerk nor the Excise Guard through whom the sample was sent to the laboratory was examined in this case to prove the tamper-proof despatch of the sample to the laboratory and consequently, the tamper-proof despatch of the sample to the laboratory could not be established by the prosecution, which is fatal to the prosecution. For the said reason also, the revision petitioner is entitled to benefit of doubt. The courts below did not consider the above vital aspects while appreciating the evidence and consequently, the conviction and sentence passed by the courts below cannot be sustained.”
