In brief

The question

1. Whether the delay in lodging the FIR and the inconsistencies in the testimonies of PW-1 and PW-2 render the prosecution story unreliable?

The court held

The Court held that the prosecution failed to prove the charges beyond a reasonable doubt due to the inadmissible FSL report, unreliable witnesses, and lack of motive.

It also directed

The High Court allowed the appeals and set aside the Trial Court's judgment dated June 27, 2016; the Appellants were honorably acquitted and ordered to be released forthwith.

The Court further issued systemic "Suggestions" for mandatory SOPs, requiring FSL experts to include qualifications, scientific reasons, and storage conditions in future reports.

01Facts

The Appellants were convicted by the Trial Court under Sections 302/34 and 328/34 of the IPC for allegedly murdering Jagdish (Gyanmati’s husband) by administering Aluminium Phosphide in his food on July 20, 2013.

p. 3

The prosecution alleged an illicit relationship between the Appellants as the motive.

p. 3

While the FIR was lodged with a two-day delay on July 22, 2013, the medical records (Ex. Ka-4) showed Gyanmati herself admitted the deceased to the hospital.

p. 5, 8, 16

The post-mortem could not ascertain the cause of death, but a subsequent Forensic Science Laboratory (FSL) report found traces of poison in the viscera.

pp. 8-9

The Appellants contended they were falsely implicated and had actually provided prompt medical care.

pp. 10-11

02Issues

i.1. Whether the delay in lodging the FIR and the inconsistencies in the testimonies of PW-1 and PW-2 render the prosecution story unreliable?

pp. 14-17

ii.2. Whether an FSL report lacking scientific data, reasons, or testing protocols is admissible as expert evidence under Section 45 of the Evidence Act?

pp. 17-22

iii.3. Whether the prosecution discharged its burden of proving safe preservation of the viscera sample and the specific cause of death?

pp. 34-36

03Law Applied

The court applied Section 302 (Murder) and Section 328 (Causing hurt by poison) of the IPC.

p. 2

The court relied on Section 45 of the Indian Evidence Act regarding expert opinions and Section 293 of the CrPC regarding reports of Government scientific experts.

pp. 17-18

The court strictly applied the principles from Madan Gopal Kakkar v. Naval Dubey and Ramesh Chandra Agrawal v. Regency Hospital Ltd., which mandate that an expert opinion must be supported by "data and material" and "reasons" to enable the court to form an independent judgment.

pp. 20-21

The court noted the nature of Aluminium Phosphide as established in Jaipal v. State of Haryana, observing it is rarely accidental/homicidal due to its pungent odor.

pp. 32-33

04Reasoning

The Court found the testimonies of PW-1 and PW-2 (father and Pradhan) regarding the "dying declaration" and hospitalization to be "entirely false," as hospital records proved the wife (Appellant) brought the deceased to the hospital, contradicting the witnesses’ claims.

pp. 16-17

The Court rejected the FSL report (Ex. Ka-14) because it merely stated a conclusion (identifying poison) without disclosing any tests, scientific criteria, or raw data, rendering it inadmissible.

p. 22

The Court also highlighted the prosecution's failure to prove the integrity of the "chain of custody," noting that the viscera was tested over a year after collection without evidence of safe lab storage.

pp. 35-36

The doctor (PW-4) was never confronted with the FSL findings to confirm if internal symptoms matched the alleged poison.

p. 34

The Court concluded that the Appellant's conduct—immediately seeking medical help—was inconsistent with a homicidal intent.

p. 36

05Holding

The Court held that the prosecution failed to prove the charges beyond a reasonable doubt due to the inadmissible FSL report, unreliable witnesses, and lack of motive.

p. 37

The High Court allowed the appeals and set aside the Trial Court's judgment dated June 27, 2016; the Appellants were honorably acquitted and ordered to be released forthwith.

p. 37

The Court further issued systemic "Suggestions" for mandatory SOPs, requiring FSL experts to include qualifications, scientific reasons, and storage conditions in future reports.
