Dorman Long And Co. Ltd. v. Jagadish Chandra Mahindra And Anr.

In the world of intellectual property, winning a patent is not just about invention—it is about navigating procedure. A groundbreaking idea means little if the applicant cannot master the rules of engagement before the patent office. The case of Dorman Long and Co. Ltd. versus Jagadish Chandra Mahindra stands as a timeless reminder that even legitimate grievances can falter when litigants reach for the wrong legal tool at the wrong time.

Dorman Long and Co. Ltd., a company engaged in industrial and engineering work, found itself entangled in a patent dispute before the Controller of Patents. The proceedings had reached a stage where Dorman Long believed it needed the testimony of expert witnesses to strengthen its position. To compel the appearance of these experts, the company requested that subpoenas be issued. The Controller of Patents, however, refused to grant these subpoenas. Dissatisfied with this administrative decision, Dorman Long escalated the matter by approaching the court, seeking a writ of certiorari or a mandatory injunction to compel the Controller to allow the witnesses to be summoned and heard.

Dorman Long argued that it still possessed the right to present evidence in its own defense, and that the Controller's refusal to issue subpoenas effectively stripped it of that right. The company contended that the extraordinary remedy of certiorari—or alternatively, a mandatory injunction—was necessary to correct what it viewed as an improper exercise of administrative authority. On the other side, the respondents, including Jagadish Chandra Mahindra, countered that the Controller of Patents had acted well within the scope of his discretionary powers. The central legal friction was whether a court should intervene in the procedural decisions of a specialized tribunal, and whether the petitioners had exhausted or even identified any other adequate legal remedy available to them before seeking such extraordinary relief.

The court ultimately dismissed the appeal, ruling in favor of the defendants. It held that the Controller of Patents' decision to refuse the subpoenas was a matter falling within his legitimate discretion, and that the petitioners had failed to demonstrate the absence of other specific and adequate legal remedies—a fundamental prerequisite for invoking extraordinary jurisdiction. Because Dorman Long could not satisfy this strict condition, neither the writ of certiorari nor the mandatory injunction was warranted. The appellate court declined to overturn the Controller's order, leaving the original administrative decision intact.

For founders, inventors, and IP professionals, this case delivers a critical procedural lesson: extraordinary legal remedies are not shortcuts. Before seeking writs or injunctions against administrative bodies like patent offices, litigants must be certain that no other adequate remedy exists. In patent and IP disputes, understanding the boundaries of administrative discretion—and exhausting ordinary remedies first—is essential. Aggressive legal tactics may feel justified, but without the right procedural foundation, even a strong substantive position can collapse in court.
