Order VI Rule 17 CPC: Due Diligence, Trial Commencement and Limitation

Do not wait for the first witness to enter the witness box

The earlier guide stated an overly narrow threshold: that trial begins only when the first witness is called or substantive evidence is led.

In Mohinder Kumar Mehra, paragraphs 9–11, the Court explained the stage after issues are framed and the matter is fixed for evidence. It also discussed the significance of an affidavit in lieu of examination-in-chief. In that case, it said trial had technically commenced when the date was fixed for the plaintiff's evidence, although the amendment application preceded the actual evidence.

The amendment was ultimately allowed on the particular procedural facts. The decision is not permission to ignore the proviso whenever oral testimony has not yet begun. Check the actual orders and evidence stage.

Limitation is not an automatic yes-or-no label

In Life Insurance Corporation of India v. Sanjeev Builders Private Limited, decided on 1 September 2022, paragraphs 19 and 70–72, the Supreme Court rejected an absolute rule that every amendment raising a limitation issue must fail.

Relevant considerations include whether the change introduces an entirely new case, deprives the opponent of an accrued defence, or merely supplies particulars or a different approach on facts already pleaded. Where limitation is arguable, an amendment may be allowed while leaving that issue for determination.

The Court upheld the amendment in that case, which increased an existing alternative damages claim in a specific-performance suit. The earlier guide misleadingly presented it principally as a decision rejecting new claims or imposing a heightened post-trial test.

Admissions, prejudice and the nature of the case

Paragraph 70 of Sanjeev Builders protects clear admissions that confer a right on the opponent and valid defences that an amendment would remove. It also distinguishes an entirely new case from a change in relief based on facts already pleaded.

Delay alone does not settle every application. The court considers necessity, bona fides, prejudice, the nature of the proposed change and the applicable due-diligence requirement. Avoid treating categories of amendments as freely available at every stage.

Preparing the application

Set out the exact proposed edits and explain their relevance to the dispute. Address limitation and admissions expressly. Identify the trial stage and, where required, demonstrate due diligence with dates and documents. Explain how the opponent can fairly respond and any resulting costs or further evidence.

These procedural questions require assessment on the case record; the cited judgments do not guarantee permission to amend.

Correction — 20 October 2026: Corrected the overly late trial-commencement threshold, the absolute limitation bar and the account of Sanjeev Builders; clarified due diligence and protection of accrued defences.
