The Supreme Court warned investigators and courts against building criminal cases on public perception or personal bias, warning that such an approach could obstruct justice by endangering innocent people while allowing the real perpetrator to escape.

A bench of Justices Sanjay Kumar and K Vinod Chandran said that over-zealous investigations based on assumptions rather than evidence can harm the criminal justice process such as inactive or delayed investigations.
“Excessive investigation is as fatal to prosecution as inactivity and tardiness. Framing the case on the basis of public perceptions and personal inclinations ends up in chaos, often endangering the innocent and always letting the offender go free,” the court said in its ruling on Wednesday.
This observation came as the court upheld the acquittal of a man and his wife accused of killing his parents by setting fire to their home in Bihar state in 2016.
The court stressed the human cost of wrongful prosecution, noting that the trauma of arrest, imprisonment and trial can leave lasting effects on those who are later proven innocent. “The trauma of arrest, imprisonment and trial will always terrorize the couple and, more so, their children who were left orphaned during the period when their parents were imprisoned,” the bench said.
Although the defendants were ultimately acquitted, the court highlighted that the stigma of being accused of killing their parents would likely remain. “A couple was burned to death, at the sad end of their lives, and the cause, whether murder or accident, is far from civil society,” the court said, adding that the shadow of suspicion cast on the family will continue to haunt them.
She further stressed that “when lives are lost or lost, and there is a possibility of false accusations being made, investigators and courts must strive to do better and follow accepted practices and procedural rules to the greatest extent.”
The case relates to the death of an elderly couple whose house was destroyed by fire in the early hours of November 23, 2016. The husband died on the spot while his wife succumbed to her injuries two days later in a Patna hospital. Prosecutors alleged that the younger son and his wife set fire to the hut over a long-standing property dispute.
A lower court convicted the couple of murder, but the Patna High Court later acquitted them, finding serious holes in the prosecution’s case. The Supreme Court has now affirmed the acquittal, holding that the investigation and trial were fundamentally flawed.
Bihar was represented by advocate Azmat Hayat Amanullah, while senior advocate Vipin Sanghi assisted by advocate Vikas Singh Jangra appeared for the acquitted couple.
The court said that the entire case appeared to be based almost exclusively on the alleged motive of property-related animosity between father and son, without establishing a reliable chain of evidence linking the accused to the crime. She added that the investigation appears to have been influenced by the village’s sentiments against the accused.
“The entire village was against the son and the incident ended in an investigation where the truth was sacrificed on the altar of perceived revenge,” the court said, further noting that the investigating officer’s “selective but reckless prosecutions” derailed the trial.
The authority added that the evidence presented in court failed to meet the strict standards required in criminal trials, where guilt must be proven beyond a reasonable doubt. In this case, she said that the circumstances presented by the prosecution do not constitute a complete chain that only points to the guilt of the accused. Instead, the record indicated a conscious effort to pin the crime on the son and his wife.
The court also pointed to serious shortcomings in the investigation, including the failure to question key witnesses who recorded the death announcement, and the absence of basic forensic procedures. According to the ruling, the scene of the fire was not properly documented, a forensic examination was not conducted, and several independent witnesses who were present at the scene were not questioned in court. Even the individuals who allegedly took the injured woman to the hospital were not presented as witnesses.
The court noted that the prosecution relied largely on the testimonies of “interested witnesses,” many of whom were closely related to the deceased or had an interest in the ownership dispute. It also indicated that none of the witnesses were able to prove that the accused was near the crime scene at the time of the incident.
In conclusion, the Supreme Court urged investigators and trial courts to strictly adhere to established investigative practices and procedural safeguards in criminal cases.
