HWL Ebsworth Lawyers v Persons Unknown

The case of HWL Ebsworth Lawyers v Persons Unknown involves a national law firm, HWL Ebsworth Lawyers, who are plaintiffs in the proceedings. The defendants are unidentified Internet hackers who stole data from the plaintiffs' private databases. The dispute was heard in the Federal Court of Australia, where the plaintiffs sought an interlocutory injunction against the hackers, referred to as “persons unknown”. The plaintiffs were granted the injunction, and orders were made to bring the summons and affidavits to the attention of the unknown hackers. The hackers did not appear in court, leading the plaintiffs to seek a default judgment against them.

The legal issues before the court included whether the stolen data from the plaintiffs was identifiable and whether it had the necessary quality of confidence. The court also needed to determine whether the hackers received the information under circumstances importing an obligation of confidence and whether there was actual or threatened misuse of the information. Furthermore, the court had to consider whether default judgment could be entered against the defendants described as "persons unknown" and whether injunctive relief could be granted against these unknown parties. The possibility that the defendants might be identified later and further relief sought against them was also examined.

The court found that the plaintiffs had established that the stolen data was identifiable and had the necessary quality of confidence. The hackers had received the information under circumstances that imported an obligation of confidence, and there was actual or threatened misuse of the information. The court granted the interlocutory injunction and ordered that the summons and affidavits be brought to the attention of the unknown hackers. It held that default judgment could be entered against the unknown defendants as they had not appeared to contest the application. The court also noted that while there was a possibility that the defendants might be identified later, this did not preclude the grant of injunctive relief at that time.

The court made orders for the summons and affidavits to be brought to the attention of the unknown hackers, and granted the plaintiffs an interlocutory injunction against them. Additionally, default judgment was entered against the unknown defendants. The court emphasized that while the defendants might be identified in the future, this did not affect the current orders made. The plaintiffs were thus granted the relief they sought, with the injunction and default judgment providing protection against the misuse of their confidential information by the unknown hackers.
