Legal Issues in Anton Piller KG v Manufacturing Processes Ltd
The legal issue in Anton Piller KG v Manufacturing Processes Ltd was based on the application for an interim injunction to restrain infringement, as well as an order for permission to enter the defendants’ premises to inspect and remove documents and files.
The central question was whether the court had the inherent jurisdiction to issue such an order, particularly in cases where there was a risk of vital evidence being destroyed or disposed of before an application inter partes could be made.
Anton Piller KG v Manufacturing Processes Ltd raised the fundamental legal issue of the court’s power to grant an order for inspection and removal of documents in exceptional circumstances, where there was a grave danger of vital evidence being destroyed, and the ends of justice being defeated.
The legal issue also encompassed the consideration of the defendants’ rights and the necessity for the court to act with prudence and caution in the exercise of its jurisdiction to issue such orders.
Material Facts in Anton Piller KG v Manufacturing Processes Ltd
The plaintiffs, Anton Piller KG, sought an interim injunction to restrain the defendants, Manufacturing Processes Ltd, from infringing their copyrights and disclosing confidential information.
Additionally, the plaintiffs applied for an order permitting them to enter the defendants’ premises to inspect and remove documents and files.
The plaintiffs’ solicitors prepared a draft writ of summons and, with an affidavit, went before the court to seek the interim injunction and the order for inspection and removal of documents.
The court granted the interim injunction but initially refused to order inspection or removal of the documents, citing strong prima facie evidence of the defendants’ alleged infringement.
The material facts also included the court’s consideration of the application for the order, the refusal of the defendants to permit inspection, and the subsequent appeal against the refusal.
The court’s decision to grant the order for inspection and removal of documents was based on the exceptional circumstances of the case, the grave danger of vital evidence being destroyed, and the strong prima facie case presented by the plaintiffs.
Judgment in Anton Piller KG v Manufacturing Processes Ltd
The Court of Appeal allowed the appeal, affirming the order for inspection and removal of documents.
The judgment emphasised the exceptional nature of such orders, stating that they would rarely be made and only when there was no alternative way of ensuring that justice was done to the applicant.
The court held that three essential pre-conditions must be satisfied for the making of such an order: an extremely strong prima facie case, very serious potential or actual damage to the applicant, and clear evidence that the defendants possessed incriminating documents and might destroy such material before an application inter partes could be made.
