National Australia Bank Limited & 2 Ors v Idoport Pty Limited & 4 Ors [1999] NSWSC 964

The interim injunction should continue because the legal opinion was prima facie privileged and confidential, any privilege could not be waived unilaterally, disclosure had sufficient potential to cause detriment by jeopardising privilege or giving litigation advantage, the existing undertakings lacked court sanction and were inadequate, the Defendants had not shown that their use of the confidential information was proper, and the alleged non-disclosures on the ex parte application were not sufficiently material in context to warrant discharge of the orders. The balance of convenience favoured continuance of the orders.

Procedural Posture

Equity Proceedings Concerning Interim Injunction to Protect Legal Professional Privilege or Confidential Information / Application Concerning Continuation of Ex Parte Interim Orders

Legal Issues

  1. 1 ['Whether interim orders restraining disclosure and use of a legal opinion obtained for the Plaintiffs should continue until further order.' 'Whether any legal professional privilege in the opinion had been waived where an executive summary reached the Defendants.' 'Whether the legal opinion was confidential information warranting protection by injunction.' 'Whether alleged non-disclosure by the Plaintiffs on the ex parte application justified discharge of the interim injunction.' "Whether the Defendants' communications or proposed communications about the legal advice to officers of the Plaintiffs justified injunctive relief."]

Ratio Decidendi

The interim injunction should continue because the legal opinion was prima facie privileged and confidential, any privilege could not be waived unilaterally, disclosure had sufficient potential to cause detriment by jeopardising privilege or giving litigation advantage, the existing undertakings lacked court sanction and were inadequate, the Defendants had not shown that their use of the confidential information was proper, and the alleged non-disclosures on the ex parte application were not sufficiently material in context to warrant discharge of the orders. The balance of convenience favoured continuance of the orders.

Court Disposition

Interim injunction imposed; ex parte interim orders continued until further order.

Orders

  • ['Orders made on an ex parte basis were continued until further order.' "All parties were permitted to apply to the Court on not less than two court days' notice." 'The Defendants may seek a variation of the relevant orders.']
