Holds FSL Reports Must Disclose Scientific Reasons and Data to Be Admissible
In a landmark ruling with far-reaching implications for the criminal justice system, the has held that reports that merely state conclusions without disclosing the underlying scientific data, tests conducted, or reasoning are inadmissible in evidence. The judgment, delivered by a division bench comprising Justice Ajay Bhanot and Justice Divesh Chandra Samant , resulted in the of two individuals who had been sentenced to life imprisonment for murder by poisoning.
The court underscored that an "" fails the fundamental test of under , and recommended a comprehensive set of to prevent .
A Poisoning Allegation That Unraveled
The case traced back to , when Jagdish @ Jagdhar , a resident of Sithaura village in Fatehpur district, died while undergoing treatment at the District Hospital, Fatehpur. The prosecution alleged that his wife, Gyanmati @ Sangathiya , and her alleged paramour, Ashok Kumar @ Putti Lal , had mixed Aluminium Phosphide in his meal, leading to his death.
The convicted both accused under Sections 302/34 and 328/34 of the , sentencing them to life imprisonment along with fines. However, the found the prosecution's case riddled with fatal flaws upon appeal.
The Vanishing Pillars of the Prosecution Case
The High Court systematically dismantled the evidentiary framework on which the convictions rested.
Delayed FIR and :
The court noted that the deceased died on
, at approximately 7:30 PM, yet the First Information Report was lodged only on
.
"No good cause of the delay in lodgment of the F.I.R. has been shown by the prosecution,"
the bench observed, adding that this delay
"will be
in the cumulative view of facts."
The testimonies of PW-1 Lal Singh (the deceased's father and first informant) and PW-2 Durga Prasad were found to be riddled with material inconsistencies regarding who took the deceased to the hospital and when. The court declared them "" and discarded their depositions entirely.
Hospital Records Contradicted the Prosecution: Crucially, the medical report marked as Exhibit Ka-4 established that it was the accused wife, Gyanmati, who had rushed her husband to the District Hospital at 6:25 PM. This directly contradicted the prosecution witnesses' claim that they had taken the deceased to the hospital.
The FSL Report: A Conclusion Without a Foundation
The cornerstone of the prosecution's case was an FSL report dated , which stated that Aluminium Phosphide was detected in the preserved viscera sample. However, the High Court found this report fundamentally deficient.
"The FSL report simply records the or its conclusion that Aluminium Phosphide was present in the viscera sample,"the bench observed."The report does not disclose any data, tests conducted, scientific criteria or materials which guided the expert to record the aforesaid conclusion."
Relying on the 's decisions in
Madan Gopal Kakkar v. Naval Dubey
(1992) and
Ramesh Chandra Agrawal v. Regency Hospital Ltd.
(2009), the court reiterated that an expert's opinion is admissible only when it places before the court
"all materials inclusive of the data which induced him to come to the conclusion."
The bench declared the FSL report inadmissible and discarded it.
"Could Not Be Ascertained": The Missing Cause of Death
Compounding the prosecution's woes, the post-mortem report itself stated that the . The doctor who conducted the autopsy, Dr. Sudhir Srivastava (PW-4) , was never confronted with the FSL report to verify whether the symptoms or effects of Aluminium Phosphide poisoning were reflected in the post-mortem findings.
"The prosecution has failed to establish the cause of death of the deceased by poisoning,"
the court ruled.
The Aluminium Phosphide Conundrum
To assess the plausibility of the prosecution's narrative—that the poison was mixed in dal and served—the court summoned Dr. Sapna Sharma , Associate Professor and Dean of the at the , as an expert.
Based on her testimony and authoritative texts, including Dr. K.S. Narayan Reddy's
Essentials of Forensic Medicine and Toxicology
, the court noted that Aluminium Phosphide possesses a
highly pungent, garlic-like odour
and its consumption is "mostly suicidal," with accidental ingestion being a "remote possibility." The 's decision in
Jaipal v. State of Haryana
(2003) had similarly observed that the substance
"on account of its very pungent smell... cannot be taken accidentally."
The absence of physical injuries on the deceased's body further negated any suggestion of forcible administration. This, the court held,
"gravely dents the prosecution case."
Viscera Preservation: A Critical Gap
The viscera sample was preserved on , received by the FSL on , but was tested only on —over a year later . The prosecution produced no evidence regarding how the sample was stored, whether it was kept in controlled laboratory conditions, or whether it remained fit for testing.
"The
to prove that storage conditions were safe and appropriate,"
the court stated, holding that this burden had not been discharged.
"The possibility of degradation of viscera sample during this long gap so as to render it unfit for laboratory testing is a real one."
Key Observations from the Bench
The judgment contains several significant pronouncements that will guide future criminal trials:
"The opinion of the expert which is or does not disclose the basic scientific criteria which has guided the expert to reach the conclusion is of no avail."
"The purpose of reasons in an expert report is not far to seek. The reasons stated by the expert in support of the conclusions will enable the Court to independently test the correctness of such opinion."
"The FSL was under an obligation of law to record the state of sample at the time of receipt and its fitness for purposes of testing."
"The judgment rendered by the learned trial court is and contrary to the evidences in the record."
A Sweeping Acquittal and
The High Court set aside the trial court's judgment dated , and directed the immediate release of both appellants from prison. They were "honourably acquitted" of all charges.
Recognizing systemic deficiencies, the bench issued a set of six recommendations aimed at strengthening forensic investigations:
- FSL reports must include specific reasons, scientific criteria, laboratory tests, and protocols forming the basis of conclusions.
- The qualifications and experience of the expert authoring the report must be disclosed.
- Details regarding safe preservation of samples and their fitness for testing must be recorded.
- Strict for the receipt and transfer of samples, with safeguards against tampering or degradation, must be established and disclosed.
- Doctors conducting post-mortems must be confronted with FSL findings.
- Competent authorities, including the Director General of Police and Directors of Forensic Science Laboratories, must ensure proper training of officials to implement these safeguards.
Implications for the Criminal Justice System
This ruling establishes a critical precedent: forensic evidence, no matter how sophisticated, cannot substitute for rigorous legal proof . Expert reports that fail to show their work will be treated as inadmissible, and the prosecution bears an affirmative duty to demonstrate the integrity of scientific evidence from collection through courtroom presentation.
For legal practitioners, the judgment reinforces that the of expert testimony under Section 45 of the Evidence Act is contingent upon transparency—the court must be equipped to independently evaluate the expert's reasoning, not merely defer to it. The acquittal of two individuals who had already served years behind bars serves as a stark reminder of the consequences when these principles are not observed.
