Tetra Pak Marketing Pty Ltd v Musashi Pty Ltd

Tetra Pak Marketing Pty Ltd sought an interlocutory injunction against Musashi Pty Ltd to restrain the latter from breaching an agreement to not use Tetra Pak's intellectual property in their business. The case was heard in the Federal Court of Australia. The central issue was whether Tetra Pak had established a case strong enough to warrant an interlocutory injunction, given the irreparable harm that could result from Musashi's breach of contract. The court had to assess the balance of convenience and the irreparability of harm, as well as whether Musashi had a real prospect of success at trial.

The court found that Tetra Pak had demonstrated a strong likelihood of success on the merits of its claim, as the evidence showed that Musashi had breached the agreement by using Tetra Pak's intellectual property. The court also concluded that the balance of convenience favoured Tetra Pak, given the potential for significant harm to its business if Musashi continued to use the intellectual property without authorisation. Additionally, the court noted that the harm to Tetra Pak was irreparable, as it would be difficult to quantify and remedy once Musashi had established its market presence using the intellectual property. As a result, the court granted the interlocutory injunction.

The court ordered that Musashi be restrained from using Tetra Pak's intellectual property in their business, and that it deliver up any such property in its possession. The court further ordered that Tetra Pak bring in short minutes of order to give effect to these reasons for judgment.
