Real Estate Tool Box Pty Ltd v Campaigntrack Pty Ltd

The High Court of Australia considered an appeal concerning alleged copyright infringement and authorisation of infringement. The first respondent, Campaigntrack Pty Ltd, was the owner of copyright in a cloud-based real estate marketing system known as "DreamDesk". The appellants, Real Estate Tool Box Pty Ltd, Mr Stoner, Ms Bartels, Biggin & Scott Pty Ltd, Dream Desk Pty Ltd, and Mr Meissner, were involved in the development and use of a competing software system called "Toolbox". The dispute centred on whether the appellants had infringed Campaigntrack's copyright by authorising Mr Semmens and others to reproduce elements of the DreamDesk system in the creation and use of Toolbox.

The primary legal issues before the High Court were whether the appellants, through their involvement in the development and deployment of the Toolbox software, had authorised Mr Semmens and other developers, as well as users of the Toolbox, to infringe Campaigntrack's copyright in the "DreamDesk Source Code Works", "DreamDesk Database and Table Works", and "DreamDesk PDF Works". Specifically, the court had to determine if the appellants had engaged in conduct that amounted to authorising infringement under section 36(1) of the *Copyright Act 1968* (Cth).

The High Court reasoned that for authorisation of infringement to occur, the alleged authoriser must have possessed the power to prevent the infringing acts and must have exercised that power in a way that sanctioned, approved, or countenanced the infringement. The court found that while the appellants had knowledge of Campaigntrack's copyright and the potential for infringement, they did not have the requisite power to control the specific infringing acts undertaken by Mr Semmens and the users of the Toolbox. The court emphasised that mere indifference or a failure to take steps to prevent infringement, without the power to do so, did not constitute authorisation. The High Court allowed the appeal, setting aside the orders of the Full Court of the Federal Court and dismissing Campaigntrack's appeal to that court with costs.
