  • Dates of Proceedings: 2nd, 8th December 1975

Practice Issues

  • Key Terms: Preservation of subject matter of cause of action, Inspection, Interlocutory motion, Ex parte application.

  • Order Details:
      - Required respondents to permit applicants to enter premises for inspection.
      - Circumstances for ex parte order:
        - Grave danger of evidence destruction.
        - Risk of remedy deprivation if notice is given.

  • Type of Action: Copyright infringement.

  • Context of Order: Plaintiffs (foreign manufacturers) learned defendants (agents in the UK) intended to share confidential information with rival manufacturers.

Plaintiffs’ Concerns

  • Intentions of Defendants: Suspected to supply information allowing rivals to copy the plaintiff's design of a high-frequency converter.

  • Action Taken by Plaintiffs: Desired to restrain defendants from:
      - Infringing copyright.
      - Misusing confidential information.
      - Making copies of their machines.

  • Fear of Evidence Destruction: Plaintiffs were concerned that notifying the defendants would lead them to destroy documents or transfer them out of jurisdiction prior to discovery in the action.

Ex Parte Application Context

  • Application Date: November 26, 1975.

  • Request to Court: Ultimately sought both an interim injunction and an order to inspect documents at the defendants' premises.

  • Brightman J’s Ruling (November 26, 1975):
      - Granted an interim injunction against infringement but denied the inspection order.
      - Noted the imminent possibility of evidence suppression but deemed it a risk in civil cases unless extreme circumstances exist.

Rationale Against Search Warrants

  • Legal Precedent: Established in Entick v Carrington (1765) that no warrant exists to force entry to inspect documents.

  • Nature of Orders:
      - Not equivalent to search warrants, requiring permission for entry.
      - Failure to comply could lead to contempt proceedings.

Appeal Ruling and Conditions for Order

  • Decision: Appeal was allowed; the order was issued at this court's discretion due to extreme case.

  • Necessary Pre-conditions for such Orders:
      1. Strong prima facie case should be established.
      2. Serious potential damage to the plaintiff.
      3. Clear evidence of possession of incriminating documents and a high risk of their destruction.

  • Execution of Order:
      - Not a search warrant, but an order in personam requiring defendants to allow inspection.
      - Defendants have the option to permit inspection or risk contempt of court.
      - Defendants entitled to consult solicitors before compliance.

Conclusion and Legal Reasoning

  • Denning's Perspective:
      - Order serves to put pressure on defendants to comply.
      - Essential that such an order is only made for protecting interests of justice, highlighting extreme situations.

  • Final Takeaway: The ruling indicates the court's power in exceptional situations to maintain justice, with all parties warned of the details and potential consequences.

Summary of Legal Principles Discussed

  • Nature of Interim Orders: Established as being crucial in protecting intellectual property rights in situations of potential infringement.

  • Judicial Responsibility: Significant cautiousness required to prevent misuse against defendants due to risks involved in ex parte applications.
