Section 311 CrPC allows essential evidence to be received when needed for a just decision and to prevent failure of justice.

Section 311 of the Code of Criminal Procedure, 1973 empowers the court at any stage of inquiry, trial or other proceeding to permit material evidence essential for a just decision, and the discretion must be exercised judiciously to avoid failure of justice. Applying that principle, the Delhi HC held that foundational documents relevant to the institution and maintainability of the complaint, together with a supplementary affidavit, could not be refused merely because complainant evidence had already been closed and an earlier attempt had failed. The impugned orders were set aside and the complainant was permitted to lead the additional evidence sought.

Issues: Whether the complainant should have been permitted under Section 311 of the Code of Criminal Procedure, 1973 to place on record additional foundational documents and file a supplementary affidavit in support of the complaint.

Analysis: The power under Section 311 is available at any stage of inquiry, trial or other proceeding, and it is coupled with a duty to be exercised where the evidence sought is essential for the just decision of the case. That power is to be used to discover the truth and to avoid failure of justice, though it must be exercised judiciously. The request for additional evidence was directed to foundational documents relevant to the institution and maintainability of the complaint, and the Court found that no fresh ground justified refusal merely on the basis that the complainant evidence had been closed and that an earlier attempt had failed.

Conclusion: The application ought to have been allowed, and the refusal to permit the additional affidavit and documents was unsustainable.

Final Conclusion: The impugned orders were set aside and the complainant was permitted to lead the additional evidence sought.

Ratio Decidendi: Section 311 of the Code of Criminal Procedure, 1973 must be exercised to permit material evidence necessary for a just decision where its exclusion would risk failure of justice, subject to judicious control and not as a means to cure a mere tactical omission.
