CrPC Section 334: Judgment of Acquittal on Ground of Unsoundness of Mind

Section 334 of the Code of Criminal Procedure, 1973 required a court acquitting an accused on the ground of unsoundness of mind to make a specific finding on whether the accused committed the alleged act. The corresponding provision under the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) is Section 373.

Current law: The BNSS came into force on 1 July 2024. Section 373 governs the corresponding procedure under the new code, subject to the repeal and savings provisions of BNSS Section 531 for relevant pending proceedings.

Meaning and purpose of Section 334 CrPC

The provision addresses a judgment of acquittal where the court accepts that, at the time of the alleged act, the accused was incapable, because of unsoundness of mind, of knowing the nature of the act or that it was wrong or contrary to law. Such a finding concerns the accused's mental state at the time of the act, not merely the ability to participate in a trial later.

The law requires clarity about two separate issues: whether the accused performed the alleged act, and whether the legal test for an acquittal based on unsoundness of mind is met. An acquittal on this ground must not leave the first question unanswered.

What must the court state in its judgment?

Where the accused is acquitted on the specified ground, the court's finding must expressly state whether the accused committed the act alleged. This express finding matters because further directions concerning safe custody or delivery to a relative or friend are addressed under a separate provision.

An allegation or medical diagnosis alone does not establish the statutory defence. The legal inquiry concerns the accused's capacity to understand the nature or wrongfulness of the act at the relevant time, on the evidence before the court.

BNSS Section 373: Current corresponding provision

Section 373 of the Bharatiya Nagarik Suraksha Sanhita, 2023 is titled Judgment of acquittal on ground of unsoundness of mind. It continues the substantive requirement that the acquittal finding must specifically say whether the accused committed the alleged act.

The provision must be read with BNSS Section 374, which addresses what may follow when the finding states that the accused committed the act, and with Section 531, which governs repeal and savings. The distinction between mental condition at the time of the alleged offence and present fitness to stand trial remains important.
