Accused Person as Competent Witness: Key Legal Principles in India

In criminal trials, the question of whether an accused person can serve as a competent witness often arises, balancing the right against self-incrimination with the need for fair justice. Under Indian law, particularly Section 315 of the Criminal Procedure Code (CrPC), 1973, an accused is generally not compelled to testify against themselves, protected by Article 20(3) of the Constitution. However, they may voluntarily become a competent witness for their defense or, in exceptional cases, related scenarios. This blog breaks down the rules, exceptions, and judicial interpretations based on key precedents.

Understanding these principles is crucial for accused individuals, lawyers, and anyone navigating criminal proceedings. We'll explore statutory provisions, competency tests, and practical applications.

Statutory Framework: CrPC Section 315 and Evidence Act

Section 315 CrPC explicitly states: Accused person to be competent witness.-(1) Any person accused of an offence before a Criminal Court shall be a competent witness for the defence and may give evidence on oath in disproof of the charges made against him or any person charged together with him at the same trial... This provision allows an accused to enter the witness box voluntarily via a written request, but only for defense purposes Dharmendra Kumar Tandon VS State.

Once they do so, they are treated like any ordinary witness, subject to cross-examination and liabilities for perjury Dharmendra Kumar Tandon VS State. However, they cannot be compelled to testify against themselves, reinforcing Article 20(3) Abdul Razak @ Abu Ahmed, S/o. K. P. Ahmed Kunji VS Union of India - 2021 Supreme(Ker) 610.

The Indian Evidence Act, 1872, complements this:
- Section 118 defines competency: A person is competent if they can understand questions and give rational answers. This applies to all witnesses, including accused persons opting in Appukuttan vs State Of Kerala, Represented By Public Prosecutor - 2026 Supreme(Ker) 189.
- Section 133: An accomplice is a competent witness; conviction on uncorroborated testimony is legal, though prudence suggests corroboration Kailash VS State of Rajasthan - 2005 Supreme(Raj) 2788.

Key Limitations on Accused as Prosecution Witness

An accused cannot typically testify for the prosecution in the same trial. Courts have ruled that examining a co-accused as a prosecution witness without pardon under Sections 306/307 CrPC violates self-incrimination protections Abdul Razak @ Abu Ahmed, S/o. K. P. Ahmed Kunji VS Union of India. For instance, a convict in the same offense isn't an approver and remains incompetent against co-accused Abdul Razak @ Abu Ahmed, S/o. K. P. Ahmed Kunji VS Union of India - 2021 Supreme(Ker) 610.

Competency of Special Witnesses: Children and Mentally Challenged

Competency isn't limited to accused; it extends to vulnerable witnesses. Courts must preliminarily assess if a witness—child or otherwise—understands questions and responds rationally Laxman Govind Varma VS State Of Maharashtra - 2021 Supreme(Bom) 1732.

• Child Witnesses: No age bar under Evidence Act Section 118. A child is competent if they grasp questions and truth-telling. Judges must conduct preliminary questioning; failure can vitiate trials Shambhu Baitha VS State of Bihar - 2024 Supreme(Pat) 129, Kawlthuamluaia S/o Thingremliana vs State of Mizoram - 2025 Supreme(Gau) 931.


• Mentally Challenged Witnesses: Similarly competent if capable of rational responses, as in rape cases where such testimony was upheld with corroboration Appukuttan vs State Of Kerala, Represented By Public Prosecutor - 2026 Supreme(Ker) 189.

In POCSO cases, child competency is tested strictly to prevent miscarriages of justice Sanjay VS State Of Haryana - 2022 Supreme(P&H) 1159.

Landmark Cases on Accused as Competent Witness

Judicial precedents clarify applications:

Voluntary Testimony and Risks

• In a cheating case, accused filed written statements and witness lists post-Section 313 CrPC examination. Court allowed summoning defense witnesses, affirming accused's right to lead evidence 00100047899.


• Once testifying, accused face full liabilities: Accused person is a competent witness for defence and like any other witness he is entitled to give evidence on oath... but... he subjects himself to all liabilities of an ordinary witness Dharmendra Kumar Tandon VS State.

Pardon and Approvers

• Pardon under Section 306 CrPC transforms an accused into a witness, but breach revives accused status Abdul Razak @ Abu Ahmed, S/o. K. P. Ahmed Kunji VS Union of India. Post-pardon withdrawal, they may still testify against non-jointly tried co-accused State VS Bhoora - 1961 Supreme(Raj) 4.

Convicted Persons as Witnesses

• A person pleading guilty and convicted ceases to be an accused under Section 342 CrPC (now 313) and becomes competent for prosecution Mahammad Yusuf VS Emperor - 1931 Supreme(Cal) 281, Muhammad Yusuf VS Emperor - 1931 Supreme(Cal) 80.

Related Principles: Natural Justice and Fair Hearing

Broader contexts invoke natural justice. Passport impounding requires post-order hearings Maneka Gandhi VS Union Of India - 1978 Supreme(SC) 29. Election poll cancellations demand fair hearings Mohinder Singh Gill VS Chief Election Commissioner, New Delhi - 1977 Supreme(SC) 350. These echo the audi alteram partem rule, relevant when accused rights intersect witness competency.

In disciplinary inquiries, public servants get inquiry opportunities unless public interest dispenses with them under Article 311(2) proviso Union Of India: Union Of India: Union Of India: Biswaroop Chatterjee: Achinta Kumar Biswas: Nabendu Bose: Laxmi Narayan VS Tulsi Ram Patel: Sadanand Jha: G. P. Koushal: Union Of India: Union Of India: Union Of India: State Of M. P. - 1985 Supreme(SC) 229.

Practical Implications for Accused and Courts

• For Accused: File written requests under Section 315 timely. Prepare for cross-examination; false testimony risks perjury charges.


• For Courts: Assess competency via preliminary questions, especially for children/ vulnerable. Avoid imposing unlegislated limits, as in anticipatory bail durations Siddharam Satlingappa Mhetre VS State of Maharashtra - 2010 8 Supreme 353.


• Timing: Accused can testify post-prosecution evidence, but not against co-accused without pardon E. Vanitha VS S. Lakshmi - 2017 Supreme(Mad) 1659.

| Accomplice/approver | Yes (corroborate prudently) | Evidence Act 133 Kailash VS State of Rajasthan - 2005 Supreme(Raj) 2788 |

Key Takeaways

• Accused persons are competent witnesses primarily for defense under CrPC Section 315, but voluntary choice waives some protections.


• Competency hinges on understanding questions rationally (Evidence Act 118), applicable universally.


• Exceptions like pardon or post-conviction status expand scope, but self-incrimination remains sacrosanct.


• Courts must rigorously test child/vulnerable witness competency to ensure fair trials.
