Marking a Report of a Chemical Analysis in Evidence Without Examining the Officer
Chemical Analysis Report as Evidence - Generally, a chemical analysis report alone can be admitted as evidence under section 406(3) of the Criminal Procedure Code, provided it is a report of a duly submitted sample for analysis. However, the report's evidentiary value depends on proper chain of custody, sealing, and authenticity. The officer who conducted the analysis need not always be examined if the report meets legal standards, but the prosecution must establish the integrity of the sample and the procedures followed ["
REX v. GUNAWARDENE et al.
"].Chain of Custody and Sealing - Several sources emphasize the importance of establishing the chain of custody, including proper sealing and documentation of the sample from seizure to analysis. Absence of evidence regarding seals, forwarding notes, or the sample reaching the lab can undermine the admissibility of the report. For instance, if the seal's nature or the forwarding process isn't proved, the report's evidentiary weight diminishes (2025 0 Supreme(Ker) 1728, 2025 0 Supreme(Ker) 702).
Necessity of Examining the Officer - While the report can be admitted without examining the analyst, courts often prefer the analyst to testify to confirm the procedures, authenticity, and findings, especially when issues of tampering or discrepancies are raised. The absence of the analyst's examination may be permissible if the report is properly authenticated and the chain of custody is established ["
REX v. GUNAWARDENE et al.
"], ["2025 0 Supreme(Ker) 702"].Expert Testimony and Additional Evidence - If the report involves complex analysis or questions of accuracy, courts may require the analyst's testimony to cross-examine the methodology or verify the findings. In some cases, reports are admitted as corroborative evidence rather than substantive proof unless the analyst is examined ["2023 0 Supreme(Del) 5476"], ["

"].Legal Precedents and Limitations - Courts have held that chemical reports are not always conclusive evidence unless the procedural safeguards are strictly followed. The absence of the analyst's examination, especially when the chain of custody or seals are not proved, can lead to the report being deemed inadmissible or of limited evidentiary value ["2023 0 Supreme(Ker) 835"], ["2025 0 Supreme(Ker) 702"].
Analysis and Conclusion:A chemical analysis report can be marked in evidence without examining the officer who prepared it, but only if the prosecution successfully establishes the authenticity, proper sealing, and chain of custody of the sample. The courts prefer the analyst's examination to confirm procedural compliance; however, procedural lapses regarding seals or documentation can weaken the report's admissibility. Therefore, while not strictly necessary in all cases, examining the officer enhances the credibility of the report and reduces the risk of it being challenged. Proper procedural safeguards are critical to admit such reports as substantive evidence ["2023 0 Supreme(Ker) 835"], ["
