Curtains have come down on the nearly two-decade-old legal process concerning the Nithari killings, with the main person, Surender Koli, allegedly linked to the horrific incidents of murder, rape and kidnapping, walking free after remaining in jail for approximately 19 years.
His release followed the Supreme Court’s decision to acquit him by allowing his Curative Petition in the one remaining case in which he had been convicted and was serving a life sentence. Previously, the Allahabad High Court had acquitted him in the other 12 cases, a decision which was subsequently affirmed by the Supreme Court.
A Curative Petition is the final judicial recourse available to an aggrieved person in the Supreme Court, after their appeal and subsequent Review Petition have already been dismissed. It is an extraordinary remedy invoked to prevent a “gross miscarriage of justice”.
The outcome of the Curative Petition in the Nithari case assumes significance as the general success rate of curative petitions in the Supreme Court is extremely low. The relief is designed to be granted only in the rarest of rare cases, as the Supreme Court must balance the need to correct grave errors against the need to maintain the finality of its judgments.
The Nithari Curative Petition is significant precisely because it demonstrates the Supreme Court’s willingness to breach the high wall of “finality of judgment” when a fundamental failure of constitutional justice has been unequivocally established.
Here, the Supreme Court took the extremely rare step of overriding the finality of its own previous judgments (the 2011 judgment upholding the conviction and the 2014 judgment dismissing the review petition).
The November 11, 2025 judgment delivered by a Bench comprising the three senior-most judges — Chief Justice of India (CJI) BR Gavai, CJI-Designate Surya Kant and Justice Vikram Nath allowed the Curative petition filed by Koli in the Rimpa Haldar murder case, in which his conviction was upheld from the trial court to the Supreme Court.
The judges gave the grounds for providing relief to Koli. They found that he had been acquitted in 12 companion cases based on the Nithari killings, a decision affirmed by the Supreme Court in July 2025. Yet, his conviction in the 13th case (Rimpa Haldar) rested on the identical primary evidence.
The Supreme Court noted that although Koli’s death sentence in this case was commuted to imprisonment for life on January 28, 2015, by the High Court, the conviction continues to carry the gravest consequences. To allow a conviction to stand on an evidentiary basis that this Court has since rejected as involuntary or inadmissible in the very same fact matrix offends Article 21 of the Constitution. It also violates Article 14 of the Constitution, “since like cases must be treated alike”.
“Arbitrary disparity in outcomes on an identical record is inimical to equality before the law. The curative jurisdiction exists to prevent precisely such anomalies from hardening into precedent,” said Justice Vikram Nath, writing the judgment for the Bench.
While deciding the Curative Petition, the Supreme Court questioned the reliability of Koli’s confessional statement on grounds of delay, tutoring, coercion and absence of legal aid. It held that recoveries made in connection with the case were inadmissible and unreliable and the prosecution failed to meet the fundamental standard of proof required in criminal law.
Further, the Supreme Court concluded that the forensic and medical evidence was insufficient. It only helped establish the identity of the victims and did not conclusively link the accused to the crime and observed that “Suspicion, however grave, cannot replace proof beyond a reasonable doubt. The end of the Nithari cases must be worrisome for the premier investigating agency, the Central Bureau of Investigation (CBI), as the ruling noted with “deep regret” that “negligence and delay corroded the fact-finding process” and “foreclosed avenues that might have identified the true offender.”
The Supreme Court said, “When investigations are timely, professional and constitutionally compliant, even the most difficult mysteries can be solved and many crimes can be prevented by early intervention.”
Previously, the co-accused Moninder Singh Pandher, in whose house Koli was a domestic servant, was acquitted in all six cases against him by October 20, 2023, when he was released from jail. In all cases, the Supreme Court in July 2025 upheld the acquittal of Pandher. The skeletal remains of victims, mostly children, were discovered in a drain behind his house in Noida’s Nithari village, adjacent to the national capital.
The judgment in the Curative Petition, which has come as freedom from confinement for Koli, who was arrested on December 29, 2006, when the Nithari killings came to light, must have left the victims’ families devastated and heartbroken. For them, the legal closure achieved through Koli’s release means the failure of the justice system to hold anyone accountable for the brutal serial killings of their children.
Consequently, the judgment has sparked a serious public debate regarding the devastating failure of justice for the victims’ families and how this final verdict affects public trust in the Judiciary. The central issue in the public debate stems from the fact that, after nearly two decades of trials, and with the acquittal of both prime accused (Surender Koli and Moninder Singh Pandher) in all cases, no one stands convicted for the gruesome rape and murder of multiple children and women.
Giving a purely legal perspective on the outcome of the Nithari cases, some Supreme Court lawyers, including Madhumita Bhattacharya and Namit Saxena, who are advocate-on-record at the Supreme Court, maintained that the Rule of Law has prevailed in the matter with a strong message that the highest court of this country will not shy away from curing a defect in the verdict.
Bhattacharya said, “It is not an issue of upholding public trust in the judiciary, but the judiciary has to act within the settled parameters of law. The judgment would really show that, on the same set of evidence, others were acquitted. There was no separate evidence that would single out this person. The court’s hands get tied by the investigation and its outcome and the court is duty-bound to act within the evidence presented before it. It is for the investigating agencies to be more precise and the prosecution must be more focused.” Describing the judgment in the Nithari case as “extremely crucial,” Saxena, who practices mainly in criminal law, said, "for the victims’ families, however, it is definitely a feeling of collective failure of the criminal justice administration.”
“It is important to note that it is due to a procedural flaw in the investigation that the Supreme Court found it fit to release the accused. It is time to introspect and properly guide our investigators so that such flaws do not come to favour any accused in the future,” observed Saxena. While the judgment has evoked sympathies for the victims’ family, Bhattacharya said “I as a lawyer must say that no judgment can be governed by mere sympathy because the rule of law has to prevail and this judgment is a bold step in correcting its own errors otherwise it would have led to violation of the fundamental right of a citizen who allegedly was an accused.”
So, the Supreme Court’s decision to invoke the rare Curative Jurisdiction and acquit Koli marks the definitive legal end to the harrowing Nithari serial killing cases, concluding a painful two-decade judicial journey. While the verdict affirms the Rule of Law and the Judiciary’s commitment to correcting its own “grave errors” to safeguard the fundamental rights of a citizen against faulty evidence, it simultaneously delivers a crushing blow to the victims’ families.
The resulting situation — where both primary accused walk free and no one stands convicted for the gruesome serial murders of children — underscores a profound systemic failure. As the Supreme Court itself noted with “deep regret,” the ultimate tragedy lies not with the final judgment, but with the negligent and constitutionally non-compliant investigation that corroded the evidence and “foreclosed avenues that might have identified the true offender.” Thus, the Nithari judgment serves as a pivotal, albeit devastating, lesson: a robust and professional investigation is the indispensable cornerstone upon which the entire criminal justice system, and public trust in it, must ultimately rest. So, the Rule of Law prevailed, but Justice was defeated in the Nithari cases.
