Kerala High Court Overturns Death Sentence, Cites Fatal Lapses in Trial of Assam Migrant

KOCHI – In a significant judgment underscoring the critical importance of procedural safeguards and meticulous evidence evaluation, the Kerala High Court has acquitted Parimal Sahu, a migrant laborer from Assam, who was sentenced to death for the 2018 rape and murder of a 60-year-old widow. The Division Bench of Dr. Justice Jayasankaran Nambiar and Justice Jobin Sebastian reversed the trial court's verdict, citing a cascade of fatal irregularities, including the failure to assess the competency of a key witness and the reliance on inadmissible evidence.

The ruling in Parimal Sahu v. State of Kerala serves as a stark reminder of the judiciary's role in scrutinizing every link in the chain of circumstantial evidence, especially when the stakes involve capital punishment. The High Court's detailed analysis dismantled the prosecution's case, which it found was built on a foundation of unreliable testimony, doubtful recoveries, and inconclusive scientific findings.

The Trial Court's Conviction

In 2018, Parimal Sahu, who rented a room in the same compound as the victim in Puthanvelikkara, Ernakulam district, was accused of brutally assaulting, raping, and murdering the 60-year-old woman. The prosecution alleged that Sahu trespassed into her home, struck her with a granite stone, committed rape, and then strangled her to ensure her death. To mislead investigators, he allegedly smeared blood on the t-shirt of the victim's intellectually disabled son.

The Additional Sessions Judge, North Paravur, found Sahu guilty of offences under Sections 449 (House-trespass), 376A (Rape causing death), 302 (Murder), and 201 (Causing disappearance of evidence) of the Indian Penal Code. He was sentenced to life imprisonment for murder and received the death penalty for the offence under Section 376A, which was subject to confirmation by the High Court.

The Unexamined Witness: A Fatal Flaw

The prosecution's case hinged almost entirely on the testimony of the victim’s 35-year-old son (PW4), an intellectually disabled man with a certified mental age of seven and a half years. He was the sole purported eyewitness to the crime. However, the High Court found a critical and "fatal irregularity" in how his evidence was handled: the trial court had failed to conduct a voir dire examination.

A voir dire is a preliminary examination to determine the competency of a witness to testify, a crucial step mandated by Section 118 of the Indian Evidence Act, particularly for vulnerable witnesses. The High Court observed that this omission cast serious doubt on the reliability of the son's testimony.

"The non-conduction of voir dire examination will certainly create serious doubts regarding the competence of PW4 (the son) to depose and the reliability of his version, particularly when a vulnerable witness like PW4 is inherently susceptible to tutoring," the Bench stated.

While the absence of a voir dire test is not an automatic ground for discarding testimony, the Court clarified it imposes a heightened duty on both the trial and appellate courts to scrutinize the evidence with "meticulous care." Upon such scrutiny, the Bench found glaring inconsistencies. The witness, PW4, gave a relatively coherent account during his chief examination but was unable to provide cogent answers to even simple questions during cross-examination. This disparity, the Court surmised, "strongly suggests that he was a tutored witness."

Concluding this point, the Court held that the failure to conduct the competency examination was a "fatal irregularity" and excluded PW4's testimony from consideration, effectively collapsing the primary pillar of the prosecution's case.

Dismantling the Circumstantial Evidence

With the eyewitness testimony discredited, the High Court proceeded to meticulously dissect the circumstantial and scientific evidence presented by the prosecution, finding each piece insufficient to prove guilt beyond a reasonable doubt.

1. The Inadmissible Confession: The prosecution relied on an extrajudicial confession Sahu allegedly made to doctors at a government hospital during his medical examination post-arrest. However, since Sahu was in police custody at the time, his counsel argued the confession was inadmissible under Section 26 of the Evidence Act. The High Court agreed, adopting an expansive interpretation of "custody."

“In the light of the recent pronouncements of the Supreme Court that have enlarged the scope of the phrase “custody”... the mere fact that the policemen who brought him to the hospital for medical examination were standing outside the examination room did not bring him outside the scope of the phrase 'person whilst in Police custody' for the purposes of S.26 of the Evidence Act,” the Court remarked.

2. The Doubtful Recovery of the Weapon: The recovery of the granite stone (the alleged murder weapon) under Section 27 of the Evidence Act was also found to be highly questionable. The stone was recovered from an open area within the victim's compound, a place accessible to the public and already scoured by the police and locals. The investigating officer did not claim the accused produced the stone from a concealed position. This, the Court noted, raised serious "concerns about potential manipulations."

3. Unreliable Scientific Evidence: The scientific evidence, far from cementing the prosecution's case, appeared to exonerate the accused. Key findings included: * DNA Evidence: While semen was detected in vaginal swabs from the deceased, the sample was insufficient for DNA typing, meaning it could not be linked to the accused. * Nail Clippings: No epithelial cells of the accused were found in the victim’s nail clippings, nor were the victim’s cells found on the accused, undermining the theory of a physical struggle. * Bite Marks: The prosecution claimed bite marks on Sahu’s hand were from the victim. The Court found this evidence unreliable, noting procedural lapses (examination by a dentist, not a registered medical practitioner) and the fact that "bite mark comparison was not an exact science." The Court also found the defense's contention that the marks could have been caused by police torture to be probable.

The Bench concluded that the scientific evidence, rather than proving the accused's involvement, "tends to help the accused in establishing his innocence."

4. Other Weak Circumstances: The prosecution also pointed to a phone call Sahu made to an acquaintance (PW5), allegedly asking him to provide an alibi. The Court dismissed this, noting PW5 was not a reliable witness and that it was not unnatural for a migrant laborer, apprehensive of being falsely implicated, to make such a call.

A Judgment with Broader Implications

The acquittal of Parimal Sahu, who was represented with legal aid from The Square Circle Clinic, NALSAR, highlights systemic issues in criminal investigations and trials. The judgment serves as a powerful judicial commentary on the necessity of adhering to established legal principles, especially in capital cases.

The High Court's decision underscores several key takeaways for the legal community:

* Duty of Trial Courts: Trial judges have an indispensable duty to conduct competency examinations for vulnerable witnesses to prevent miscarriages of justice.

* Scrutiny in Capital Cases: The burden of proof remains squarely on the prosecution to establish guilt beyond any reasonable doubt, and every link in the chain of circumstantial evidence must be proven conclusively.

* Adherence to Evidence Law: The rules governing confessions and recoveries under the Evidence Act must be strictly applied to prevent coerced or fabricated evidence from influencing judicial outcomes.

By setting aside the conviction and death sentence, the Kerala High Court has not only granted liberty to Parimal Sahu but has also reinforced foundational principles of criminal jurisprudence that prioritize fairness, procedural integrity, and the presumption of innocence.
