Non-Examination of Investigating Officer Fatal to Prosecution: Patna HC Acquits Convicts in 30-Year-Old Murder Case

The non-examination of an Investigating Officer (IO) during a criminal trial, coupled with a failure to explain injuries sustained by the accused, creates an irreparable lacuna in the prosecution's case. A Division Bench of Justice Bibek Chaudhuri and Justice Rana Vikram Singh set aside a 2019 conviction of multiple individuals in a murder case dating back to 1994, emphasizing that such procedural lapses violate the foundational requirements of Indian Penal Code.

In three joined appeals, the Court scrutinized the judgment of the Additional Sessions Judge-I, Muzaffarpur, which had sentenced Nageshwar Singh, Shyam Nandan Singh, and others to life imprisonment for the death of one Ram Kripal Singh during a boundary wall dispute.

Key Takeaways

IO Examination Essentiality

Where material contradictions exist in witness testimonies and the place of occurrence is disputed, the non-examination of the Investigating Officer is fatal to the prosecution.

Unexplained Accused Injuries

Failure by the prosecution to explain serious injuries sustained by the accused suggests a suppressed version of events, specifically regarding mutual fighting.

Benefit of Alibi

Successful substantiation of a plea of alibi, supported by defense witnesses like a Village Chaukidar, can lead to the acquittal of specific accused even if others are present.

Corroboration of Medical Evidence

Non-examination of the autopsy surgeon prevents the formal proof of the post-mortem report, weakening the nexus between the alleged act and the cause of death.

Fatal Procedural Lapses and Benefit of Doubt

The Court observed that the prosecution failed to examine the IO who recorded the initial fard beyan and conducted the spot investigation. Referring to Lahu Kamlakar Patil and Anr. v. State of Maharashtra ( "2013 AIR SCW 26": 2012 CaseBase(SC) 497), the Bench noted that while non-examination of an IO is not always fatal, it becomes a "lacuna" when the defense suffers prejudice or when material contradictions remain unresolved. The Court highlighted that the IO failed to seize offending weapons or even the bricks allegedly used to demolish the wall, leaving the physical evidence of the crime scene unproven.

Furthermore, the Court identified that a cross-case (Puranki P.S. Case No. 86 of 1994) had been filed by the accused party. "Existence of mutual fighting by and between the family members of the informant and the accused persons, receipt of injuries on the person of the accused persons also, non-explanation of the injuries received by the accused persons makes the foundational edifice of the prosecution case absolutely with to tumble down," the Bench remarked.

Ratio

In a trial involving charges under Section 302 of the Indian Penal Code, the failure to examine the Investigating Officer results in a fatal defect if it prevents the defense from proving material contradictions or if the recovery of weapons and the scene of occurrence remain unverified. Additionally, where both parties engage in mutual fighting and the prosecution fails to explain the injuries sustained by the accused, the court must lean towards the innocence of the accused by granting the benefit of doubt.

Background

The dispute originated on June 23, 1994, in Muzaffarpur, Bihar, when the informant's family attempted to raise the height of a boundary wall. The accused persons allegedly arrived, demolished the wall, and upon being resisted, returned with lethal weapons. It was alleged that Shyam Nandan Singh assaulted the deceased with a spear, while others used Lathis and Daabs (sharp weapons) to injure family members.

During the trial, the defense argued that Shyam Nandan Singh was a Jamadar at Malahi Police Station and was executing a warrant elsewhere at the time of the incident, a plea of alibi supported by a Chaukidar (D.W. 1). The Court found this defense credible and further noted that the prosecution had not produced the autopsy surgeon or the recording officer of the FIR.

Ultimately, the High Court concluded that the Trial Court erred in ignoring these contradictions and the high probability of a mutual clash where the aggressor was not clearly identified. Consequently, the conviction was set aside, and all appellants were acquitted.
