Introduction:

The case of Mangru Ratia v. The State of West Bengal came before the Calcutta High Court at its Jalpaiguri Circuit Bench in an appeal challenging the conviction and life sentence imposed by the trial court in 2019 for the murder of the appellant’s wife. The Division Bench comprising Justice Debangsu Basak and Justice Biswaroop Chowdhury was called upon to examine whether the conviction based on circumstantial evidence was sustainable in law. The prosecution case revolved around a brutal incident that occurred inside the matrimonial home of the appellant during the early hours of the day. The deceased was found in the kitchen with multiple grievous injuries, lying in a pool of blood, while the appellant was seen fleeing from the scene. The case rested significantly on the testimony of the victim’s daughters, corroborative evidence from neighbours, medical findings, and the surrounding circumstances indicating a strained marital relationship marked by allegations of domestic violence. A crucial aspect of the case was the complete failure of the appellant to offer any explanation regarding the circumstances leading to his wife’s death despite being present in the house at the relevant time. This silence attracted the presumption under Section 106 of the Indian Evidence Act, placing a burden on the appellant to explain facts within his special knowledge. The High Court was thus tasked with determining whether the chain of circumstantial evidence was complete and whether the presumption under Section 106, coupled with the evidence on record, justified affirming the conviction and sentence imposed by the trial court.

Arguments:

On behalf of the appellant it was contended that the conviction was unsustainable as it was based entirely on circumstantial evidence which according to the defence was incomplete and insufficient to establish guilt beyond reasonable doubt. The appellant’s counsel argued that there was no direct eyewitness to the actual act of murder and that the prosecution had failed to conclusively prove that the appellant was the perpetrator of the crime. It was submitted that the testimony of the victim’s daughters, though relied upon by the prosecution, could not be treated as wholly reliable due to the emotional and familial context in which it was given. The defence attempted to cast doubt on their version by suggesting the possibility of exaggeration or misinterpretation of events. It was further argued that the alleged recovery and seizure of the weapon of offence, namely the axe, was not proved in accordance with law and therefore could not be relied upon as a material exhibit. The defence placed reliance on judicial precedent including the case of Rasan Hansda to contend that in cases based on circumstantial evidence the chain of circumstances must be so complete as to exclude every hypothesis except that of guilt and that any missing link would entitle the accused to benefit of doubt. The appellant’s counsel also argued that mere presence of the accused in the house or his subsequent conduct of fleeing could not by itself establish guilt in the absence of direct evidence. It was submitted that the prosecution had failed to rule out the possibility of involvement of some other person and that the burden of proof always remained on the prosecution. The defence further contended that the presumption under Section 106 of the Evidence Act could not be invoked to fill gaps in the prosecution case and that the accused’s silence under Section 313 CrPC could not be treated as substantive evidence of guilt. On the other hand the State strongly supported the findings of the trial court and argued that the prosecution had successfully established a complete and unbroken chain of circumstances pointing unerringly towards the guilt of the appellant. The prosecution emphasised the consistent and cogent testimony of the victim’s daughters who had rushed to the kitchen upon hearing a commotion and had witnessed the appellant fleeing through the window while their mother lay grievously injured. It was submitted that their testimony remained unshaken during cross examination and was corroborated by independent witnesses including neighbours who arrived at the scene shortly thereafter and found the deceased lying in a pool of blood with the appellant missing from the house. The State further relied on the medical evidence which clearly established that the death was homicidal in nature and caused by multiple sharp cut injuries inflicted by a heavy weapon such as an axe. The prosecution argued that the recovery of the axe and its production during trial further strengthened the case. It was also contended that the background of strained marital relations and prior instances of physical abuse provided a strong motive for the crime. Witnesses including a Panchayat member had testified that the deceased had expressed fear for her life due to the appellant’s conduct. The prosecution placed significant reliance on Section 106 of the Evidence Act submitting that since the death occurred inside the matrimonial home in the presence of the appellant it was incumbent upon him to explain the circumstances leading to the death. His complete failure to do so coupled with his conduct of fleeing the scene provided an additional link in the chain of circumstances. The State argued that the defence had failed to offer any plausible alternative explanation and that the cumulative effect of the evidence left no reasonable doubt regarding the appellant’s guilt.

Judgment:

The Division Bench of the Calcutta High Court after carefully considering the submissions and scrutinising the evidence on record dismissed the appeal and upheld the conviction and sentence of life imprisonment imposed on the appellant. The Court reiterated the settled principles governing cases based on circumstantial evidence and observed that such cases require the prosecution to establish a chain of circumstances so complete as to exclude every hypothesis except that of the guilt of the accused. Applying this principle to the facts of the present case the Court found that the prosecution had successfully established each link in the chain. The Court placed considerable reliance on the testimony of the victim’s daughters who were natural witnesses to the events immediately preceding and following the incident. Their evidence was found to be consistent credible and free from material contradictions. The Court noted that their testimony was corroborated by neighbours who arrived at the scene and found the deceased lying in a pool of blood while the appellant was absent. The medical evidence was found to be decisive in establishing the nature of the injuries and the cause of death. The post mortem report recorded multiple sharp cut injuries on the head and confirmed that the death was homicidal. The doctor’s opinion that such injuries could be caused by a heavy sharp cutting weapon like an axe was consistent with the prosecution case and the material exhibit produced during trial. The Court also took into account the background of strained marital relations and prior instances of domestic violence which provided a motive for the crime. The testimony of witnesses in this regard was found to be reliable and uncontroverted. A significant factor that weighed with the Court was the complete failure of the appellant to offer any explanation regarding the circumstances of his wife’s death. The Court invoked the presumption under Section 106 of the Evidence Act holding that when a fact is especially within the knowledge of a person the burden of explaining that fact lies upon him. Since the incident occurred inside the matrimonial home at a time when the appellant was admittedly present it was incumbent upon him to provide a plausible explanation. His silence under Section 313 CrPC was considered an additional circumstance strengthening the prosecution case. The Court clarified that while Section 106 does not relieve the prosecution of its burden it operates when the prosecution has established a prima facie case and the accused fails to explain facts within his special knowledge. The Court rejected the defence reliance on the precedent in Rasan Hansda observing that the facts of the present case were materially different and that the chain of circumstances here was complete and compelling. The Court further held that the appellant’s conduct of fleeing the scene immediately after the incident was indicative of guilt and could be taken into account as a relevant circumstance. Upon an overall assessment of the evidence the Court concluded that the prosecution had proved the case beyond reasonable doubt and that there was no infirmity in the findings of the trial court. Accordingly the appeal was dismissed and the conviction and sentence were affirmed with the direction that the sentence of life imprisonment shall run concurrently and that the period already undergone shall be set off in accordance with law.
