Investigative defects do not defeat conviction when credible eyewitness evidence independently proves guilt beyond reasonable doubt.

Defects or omissions in investigation, including inaccuracies in the site plan, delay in sending seized weapons for forensic examination, gaps in custody records, and non-production of bloodstained clothes, do not by themselves discredit the prosecution where credible direct eyewitness evidence establishes guilt. Hostile or related witnesses may still be relied on to the extent their testimony supports the core occurrence, and the absence of independent market witnesses is not fatal if the material witnesses are otherwise reliable. The stated principle is that investigative lapses are insufficient to disturb a conviction where the direct evidence proves the offence beyond reasonable doubt.

Issues: Whether the conviction for murder and offences under the Arms Act was liable to be set aside on the grounds of alleged defects in the site plan, delay in sending seized articles for forensic examination, absence of proof of safe custody, non-production of bloodstained clothes, and reliance on related or hostile witnesses.

Analysis: The challenge was founded on alleged omissions in the site plan and the submission that such omissions cast doubt on the presence of eyewitnesses. The Court held that a site plan prepared by the investigating officer cannot be used to discredit direct ocular testimony when the eyewitnesses have been examined on oath, and omissions in the plan, by themselves, do not render the prosecution version doubtful. The Court further held that delay in forwarding the weapon and cartridges, or absence of some custody records, did not by itself demolish the prosecution case where the forensic packets were received sealed and intact and the direct evidence consistently implicated the appellant. The non-production of the witness's bloodstained clothes was treated as an investigative lapse which did not outweigh the eyewitness account. The evidence of hostile witnesses was also considered to the extent it supported the prosecution on the firing incident, and the absence of independent market witnesses was held not fatal when the material witnesses were otherwise credible.

Conclusion: The alleged investigative deficiencies did not create a reasonable doubt in the prosecution case, and the conviction was upheld.

Final Conclusion: The appeal failed because the direct eyewitness evidence was found reliable and the pleaded defects in investigation were held insufficient to disturb the findings of guilt.

Ratio Decidendi: Defects or omissions in investigation, including in the preparation of the site plan or custody of seized articles, do not warrant acquittal where credible direct eyewitness evidence independently establishes guilt beyond reasonable doubt.
