THE HIGH COURT OF KARNATAKA
Mohammad Nawaz, Venkatesh Naik T, JJ
State of Karnataka – Appellant
Versus
Mohammed Tansif – Respondent
CRIMINAL APPEAL NO. 2439 OF 2025



Advocates:
For the Appellants/Petitioners: Rashmi Patel

In criminal trials, scientific evidence like DNA profiling requires an untainted chain of custody to be admissible for conviction; when witnesses turn hostile and sample-handling protocols are not proven, the trial court's order of acquittal based on reasonable doubt should not be disturbed by the appellate court.

Headnote:(A) Protection of Children from Sexual Offences Act, 2012 - Section 6 - Indian Penal Code, 1860 - Sections 354A, 376(2)(h) and 376(2)(n) - Appeal against acquittal - DNA evidence - Integrity of samples - Prosecution failed to establish the safe method of collection, preservation, and transportation of biological samples - Trial Court acquitted the accused after recording that the victim and her mother turned hostile and the DNA evidence could not be considered as gospel truth without reliable corroboration and proof of the chain of custody. (Paras 11, 12, 16)

(B) Appellate Court - Scope of interference in acquittal - Principle of double presumption of innocence - Appellate court should not interfere with an order of acquittal unless the view taken by the trial court is perverse or illegal. (Paras 17-20)

Facts of the case:
The State preferred an appeal against the acquittal of the accused for offences involving sexual assault on a minor victim. The prosecution case relied heavily on a DNA report identifying the accused as the biological father of the child born to the victim. However, the victim and her mother turned hostile during the trial, and serious questions were raised regarding the handling and chain of custody concerning the DNA samples.

Findings of Court:
The Court held that the prosecution failed to establish the necessary chain of custody and standard protocols for DNA sample preservation, leading to the risk of tampering. Given the witness hostility and the lack of reliable corroborating evidence, the trial court's acquittal was upheld.

Issues: Whether the DNA report is sufficient to convict the accused in the absence of corroborative evidence and when the prosecution fails to establish the integrity of the sample collection and handling process.

Ratio Decidendi: While modern science like DNA profiling is an effective tool, it must be supported by a proper chain of custody. When human agencies control the process of evidence collection, potential for manipulation exists, and therefore, an order of acquittal cannot be reversed solely on the basis of scientific evidence if the integrity of the underlying process is challenged and not proven.

Result: Appeal dismissed.
