Pleadings may be amended to explain trademark-rights origins without introducing a new cause of action.

Sri Balamurugan Match Works sued for a permanent injunction alleging infringement of its registered “Acha Dholak” trade mark and related artistic work.

The defendants filed their written statement, and issues were framed.

The plaintiff then sought to amend its plaint to plead details about the business’s origin and constitution, its father’s role in establishing the business and obtaining a licence/registration, and the subsequent transfer or continuation of the business with the plaintiff.

The defendants opposed the application, arguing that it introduced a new case and cause of action, was not supported by the due diligence required after commencement of trial, and would fill gaps in the plaintiff’s case.

The trial court allowed the amendment; the defendants challenged that order under Article 227 of the Constitution.

1. Whether the proposed amendments introduced a new cause of action or fundamentally changed the nature of the suit.

2. Whether the plaintiff satisfied the due-diligence requirement under the proviso to Order VI Rule 17 CPC, and whether the trial court’s order warranted interference under Article 227.

Order VI Rule 17 CPC empowers the court to permit amendments necessary to determine the real questions in controversy; after commencement of trial, its proviso requires the applicant to show that, despite due diligence, the matter could not have been raised earlier.

Under Revajeetu Builders and Developers v. Narayanaswamy & Sons, (2009) 10 SCC 84, the court considers whether an amendment is necessary to resolve the real controversy and whether it causes prejudice that cannot be adequately addressed.

Delay alone is not an absolute bar where the amendment is necessary and does not fundamentally alter the suit.

In exercising Article 227 jurisdiction, interference is not warranted absent jurisdictional error or material irregularity in the trial court’s exercise of discretion.

The Court found that the proposed pleadings concerning the business’s origin and continuity were connected to the plaintiff’s existing claim over the registered trade mark and did not introduce an unrelated cause of action.

Although the application followed the framing of issues, the Court noted the plaintiff’s explanation that relevant records had been traced later and that the amendment application followed on legal advice; the framing of issues alone did not establish that trial had substantially commenced.

The defendants could respond to the amended pleadings, and any dispute about the plaintiff’s entitlement, the effect of the licence or registration, or the Trade Marks Act provisions raised by the defendants could be determined on the pleadings and evidence rather than used to reject the amendment.

The trial court’s decision therefore disclosed no jurisdictional error or material irregularity.

It directed the trial court to proceed with the suit in accordance with law and permitted the defendants to file an additional written statement, if advised; there was no order as to costs.
