Karnataka HC: Trial Court Cannot Ignore Credible Plea of Alibi While Recording Conviction

The Karnataka High Court has set aside the conviction of a man under Section 307 of the Indian Penal Code (IPC) in a case involving an alleged acid attack, holding that material contradictions in the prosecution evidence coupled with credible oral and documentary evidence supporting the accused’s plea of alibi created serious doubt about the prosecution case.

In D. Nagaraju v. State by Girinagar Police, Justice S. Rachaiah allowed Criminal Appeal No. 472 of 2017 and overturned the judgment dated 9 March 2017 of the LXIV Additional City Civil and Sessions Judge, Bengaluru. The High Court ultimately acquitted the appellant of the offence punishable under Section 307 IPC.

The ruling is significant for its treatment of identification evidence, hostile witnesses, contradictions in eyewitness testimony, documentary proof of an alibi and the obligation of a criminal court to consider defence evidence before sustaining a conviction.

Background of the Case

• According to the prosecution, the complainant was working as an Apprentice Trainee at BHEL, Bengaluru when a marriage proposal was initiated between her and the accused. Their families initially agreed to the marriage.
• After she was appointed as a Junior Engineer with KPTCL and posted at Shahabad, the accused continued meeting her. Their marriage was scheduled for 13 February 2005, but on the previous day, the accused allegedly informed her that his father was unwilling to proceed with the marriage.
• The complainant became distressed and consumed poison, but survived after receiving medical treatment. According to the prosecution, the accused subsequently resumed contact with her and began residing with her. A second marriage date was eventually fixed for 26 January 2006.
• The prosecution alleged that the complainant subsequently discovered that the accused had already married another woman. When confronted, he allegedly denied the marriage and was asked to leave the complainant’s house.

Alleged Acid Attack

• The prosecution alleged that on 19 July 2006, at around the time the complainant was proceeding to catch a bus for work at HAL, the accused arrived on a motorcycle, threatened her and poured acid on her with the intention of causing her death.
• The complainant suffered injuries to her right arm, right side of the neck and face. Her statement was subsequently recorded in hospital, following which the police registered a case, investigated the matter and filed a charge sheet.
• The Trial Court eventually convicted the accused under Section 307 IPC.
• Aggrieved, he approached the Karnataka High Court under Section 374(2) of the Code of Criminal Procedure.

Prosecution Evidence Before the Trial Court

• The prosecution examined 18 witnesses, marked 36 documents and identified nine material objects.
• The defence, on the other hand, examined five witnesses and produced 12 documents.
• However, several prosecution witnesses did not fully support the prosecution’s version.

The High Court noted that:

• PW-1 was the complainant and injured witness;
• PW-2 was stated to be an eyewitness but only partly supported the prosecution;
• PW-3, the complainant’s mother, was a hearsay witness;
• PW-4, the complainant’s sister, was not an eyewitness;
• PW-5, the chemical shop owner who was expected to speak about the alleged purchase of acid, turned hostile;
• PW-6, a panch witness, did not support the prosecution;
• PW-7, the owner of the motorcycle allegedly used in the offence, also turned hostile; and
• PW-9 initially did not support the prosecution, although he later admitted during cross-examination that a material object had been seized in his presence.

These evidentiary deficiencies assumed considerable importance when examined alongside the defence evidence.

Defence Raises Plea of Alibi

• The central feature of the appeal was the defence’s plea that the accused was at HAL at the relevant time and therefore could not have committed the alleged attack.
• DW-1, who was working as Manager (Human Resource), HAL, Bengaluru, testified on the basis of official records that the accused was working at HAL on 19 July 2006.
• According to the attendance record produced as Exhibit D2, the accused entered the office at approximately 6:54 a.m. and left at approximately 2:26 p.m.
• Crucially, the High Court recorded that although DW-1 was cross-examined by the prosecution, nothing was elicited to disbelieve his evidence.
• This was not the only evidence supporting the alibi.
• DW-3, another HAL employee and a friend of the accused, testified that he had met the accused at the HAL main gate at around 6:10 or 6:15 a.m. and that the accused remained with him during the period between approximately 6:10 a.m. and 7:00 a.m.
• Thus, the plea of alibi was supported by both documentary evidence and oral testimony.

Identification of the Accused Came Under Doubt

• The High Court also closely examined the complainant’s evidence regarding identification.
• The complainant stated that the accused had poured acid upon her with the intention of killing her.
• However, during cross-examination, she admitted that the person who approached on the motorcycle was wearing a helmet. Although she claimed that she could recognise him, the High Court observed that she had not provided clarity regarding identification.
• This aspect became particularly significant because the accused was already known to the complainant and the prosecution case depended substantially upon her identification of him as the assailant.
• The Court was therefore required to assess whether that identification could safely sustain a conviction when considered alongside the defence’s alibi evidence.

Alleged Eyewitness Did Not Identify the Accused

• The testimony of PW-2 also weakened the prosecution case.
• Although PW-2 was described as an eyewitness, he testified that he did not see the accused.
• According to his evidence, he was inside his house when he heard the complainant screaming. When he came outside, he noticed that she had sustained burn injuries to her hand and shoulder.
• Thus, his testimony could support the fact that the complainant had sustained injuries, but it did not establish that the appellant was the person who caused them.
• The High Court consequently found ambiguities and improvements in the evidence of PW-1 and PW-2, both of whom had been projected as material witnesses concerning the occurrence.

Chemical Shop Owner Turns Hostile

• Another important weakness concerned the alleged procurement of the chemical used in the attack.
• PW-5 was the owner of the chemical shop from which the prosecution alleged that the accused had purchased the chemical.
• However, PW-5 turned hostile and did not support the prosecution case.
• Consequently, the prosecution was unable, through that witness, to establish the alleged purchase of the chemical by the accused.
• This did not independently decide the case, but it formed part of the broader evidentiary deficiencies considered by the High Court.

Defence Evidence Cannot Be Ignored

• The judgment assumes particular significance because the High Court did not restrict its examination to weaknesses in the prosecution evidence.
• It affirmatively considered the evidence led by the defence.
• The official HAL attendance record supported the accused’s presence at his workplace, and the oral testimony of defence witnesses corroborated his presence near the HAL main gate around the relevant period.
• The High Court found that the accused’s presence near HAL had been established through both documentary as well as oral evidence.
• The Trial Court’s failure to properly consider this evidence became decisive.

High Court Finds Trial Court’s Approach “Arbitrary and Illegal”

• After considering the entire evidentiary record, the Karnataka High Court observed that there were ambiguities and improvements in the testimony of the prosecution witnesses.
• It also considered the fact that the witness connected with the alleged purchase of chemicals had turned hostile.
• Most importantly, the Court held that the accused’s presence near the HAL main gate had been established through documentary and oral evidence.

The Court consequently observed:

• “the findings of the Trial Court in rendering the conviction without considering the plea of alibi is arbitrary and illegal.”
• The High Court concluded that the accused had succeeded in proving his plea of alibi and that the conviction was therefore liable to be set aside.

Why the Plea of Alibi Became Decisive

• A plea of alibi essentially asserts that the accused was at another place when the alleged offence occurred and therefore could not have been physically present at the scene of the crime.
• In the present case, the plea was not supported merely by the accused’s own statement.
• There was an official workplace attendance record and testimony from HAL personnel regarding his presence at or near his workplace.
• The High Court specifically noted that the prosecution’s cross-examination of the HR Manager had failed to produce anything that would justify disbelieving his evidence.
• Against this evidence, the prosecution faced difficulties concerning identification, hostile witnesses and the evidence of the purported eyewitness.
• The cumulative effect persuaded the High Court that the Trial Court’s conviction could not stand.

High Court Sets Aside Conviction Under Section 307 IPC

The Karnataka High Court ultimately allowed the criminal appeal.

It:

1. Set aside the judgment of conviction and order on sentence dated 9 March 2017 passed by the LXIV Additional City Civil and Sessions Judge, Bengaluru in S.C. No. 806/2007;

2. Acquitted the appellant of the offence punishable under Section 307 IPC; and

3. Cancelled the bail bonds, if any, executed by the appellant.

Key Legal Takeaways from the Judgment

• The decision highlights several important principles relevant to criminal trials.
• Plea of alibi must be meaningfully examined: Where an accused produces credible documentary and oral evidence showing presence elsewhere at the relevant time, the Trial Court cannot simply disregard that evidence while recording conviction.
• Defence evidence forms part of the evidentiary record: Evidence produced by an accused cannot be treated as inherently inferior merely because it originates from the defence. It must be assessed alongside the prosecution evidence.
• Identification must withstand scrutiny: Where circumstances surrounding identification are unclear—including where the alleged assailant was wearing a helmet—the reliability of identification becomes particularly important.
• Hostile material witnesses may affect the evidentiary chain: Here, the chemical shop owner did not support the alleged purchase of acid, while the motorcycle owner also turned hostile.
• Cumulative evidentiary assessment matters: The High Court’s conclusion was not based on one isolated discrepancy. It considered ambiguities in the prosecution witnesses’ evidence together with the affirmative documentary and oral evidence supporting the accused’s alibi.

Significance of the Judgment

• The decision demonstrates the importance of assessing both sides of the evidentiary record in a criminal trial.
• A serious allegation or the gravity of the injuries cannot dispense with the requirement that the prosecution case withstand judicial scrutiny. Equally, a Trial Court cannot disregard credible defence material that directly challenges the possibility of the accused’s presence at the scene.
• The judgment is especially noteworthy because the defence had produced contemporaneous employment records to establish the appellant’s presence at HAL. Once those records were supported by oral testimony and were not effectively discredited in cross-examination, they became highly relevant to determining whether the prosecution version could safely sustain the conviction.

Conclusion

The Karnataka High Court’s decision in D. Nagaraju v. State by Girinagar Police underscores the central role of careful evidence appreciation in criminal adjudication.

The High Court found material weaknesses in the prosecution case, including uncertainty surrounding identification, lack of full support from the purported eyewitness, hostile material witnesses and, most importantly, credible oral and documentary evidence supporting the appellant’s presence elsewhere.

Holding that the Trial Court had failed to properly consider the plea of alibi, the High Court characterised the resulting conviction as arbitrary and illegal, set aside the conviction under Section 307 IPC and acquitted the appellant.
