Courts stress: DNA evidence, while reliable, is not infallible and must be considered alongside other evidence, especially in cases involving vulnerable victims. 2025 Supreme(KER) 831
Judicial Stance on Negative DNA Reports
Indian courts have addressed this repeatedly, prioritizing the over isolated DNA results.
Key Case: Does Not Exonerate
In a pivotal ruling, the court clarified: A negative DNA report indicating that the accused is not the biological father of the child does not automatically exonerate the accused from rape charges. 2024 0 Supreme(Cal) 1259 Even with , victim testimony, medical exams, and can sustain charges.
When DNA Supports Guilt (Contrast for Context)

Cases Where Negative DNA Influenced Outcomes
While not conclusive, negative DNA can tip scales when combined with weaknesses in prosecution evidence.

The court noted inconsistencies in victim and sister testimonies, lack of corroboration, and prior enmity: The evidence of the victim, suffering from mental disorder, was found unreliable... DNA evidence excluded the accused as biological father. Conviction set aside. 2025 0 Supreme(Bom) 289
Proceedings Quashed: The DNA test is on the record which suggest that the petitioner is not biological father of the victim’s child... the truth must prevail. The quashed charges under , citing on DNA's validity. 2022 0 Supreme(Jhk) 818
Overturned Convictions: Where witnesses turned hostile and DNA collection lapsed: The prosecution must prove guilt beyond reasonable doubt; DNA evidence alone is insufficient if key witnesses turn hostile.

The assessment of guilt must consider all evidence, including testimonies, medical reports, and other facts, not solely DNA results. 2024 0 Supreme(Bom) 768 In vulnerable victim cases: DNA evidence along with corroborative testimonies and medical findings are used to establish guilt beyond reasonable doubt. 2024 0 Supreme(Bom) 768

- For Prosecution: Corroborate beyond DNA; secure .
- Exceptions: Rare standalone exoneration if DNA timing aligns perfectly and no other evidence.
