Understanding the Role of Additional Witnesses in Criminal Trials

On April 28, 2025, the Supreme Court of India clarified the scope of powers under Section 311 of the Code of Criminal Procedure (CrPC), which allows courts to summon additional witnesses during criminal trials. The Court ruled that a person summoned under this provision can be examined as a prosecution witness if the court determines that the person should have been included as a witness originally but was omitted due to an oversight.

Section 311 CrPC and the Role of Discretion in Summoning Witnesses

The Supreme Court elaborated that Section 311 of the CrPC grants wide discretionary powers to the Court to summon, recall, or re-examine witnesses at any stage of the trial, even after the closure of evidence. This power is designed to ensure that no valuable evidence is overlooked in the pursuit of justice. Section 311 CrPC can be invoked either suo-moto by the Court or upon an application by any party in the case.

Complementary Role of Section 165 of the Evidence Act

The Court emphasized that the powers under Section 165 of the Indian Evidence Act, which empowers the judge to put questions or order the production of evidence, are complementary to Section 311 CrPC. This enables both the prosecution and defence to request the addition of witnesses, or for the Court to do so on its own, to ensure the best possible evidence is before the court.

Distinction Between Prosecution and Court Witnesses

In this case, the Court made a distinction between summoning a witness as an additional prosecution witness and a Court witness. The Court clarified that an additional prosecution witness could be summoned if the Court finds that the person should have been included in the chargesheet but was omitted by mistake or oversight. The normal procedure for examination-in-chief, cross-examination, etc., would follow.

On the other hand, a Court witness is someone whose evidence the Court deems necessary for a just decision, even if neither party wishes to call them. The cross-examination of a Court witness is not a right, and the Court must permit it if necessary. This distinction was significant in the case before the Court, where a witness was summoned by the prosecution after being omitted from the chargesheet.

The Kannagi-Murugesan Case: Honour Killing and Witness Summoning

The ruling came in the context of the infamous Kannagi-Murugesan honour killing case, where the Court dismissed appeals filed by eleven convicts, including Kannagi's father and brother, who were involved in the honour killing of Murugesan, a Dalit man, and Kannagi, his wife. The two were murdered by her family for their inter-caste marriage.

In this case, PW-49, the step-mother of Murugesan, was not initially cited as a witness in the chargesheet by the CBI. However, during the trial, the prosecution moved an application to summon her as an additional witness under Section 311 CrPC, which was initially challenged. The Court found no issue with this approach, as the woman had been overlooked in the original investigation.

Court’s Findings on the Convictions and Compensation

The Supreme Court upheld the life sentences of the convicts, including Kannagi's father and brother, and dismissed appeals filed by two policemen for fabricating evidence in the case. The Court also granted compensation of Rs. 5 Lakhs to the parents of Murugesan as part of its judgment.

This case is significant as it underscores the Court's power to ensure that no witness with valuable information is excluded from the proceedings, and it also highlights the importance of proper legal procedure in cases of honour killings.
