Code Is Copyright: Inside the Campaigntrack v Real Estate Tool Box Trial That Reached the High Court

When a software developer copies a competitor's code to build a new product, the legal consequences can cascade upward through an entire business network. The 2021 first-instance decision in Campaigntrack Pty Ltd v Real Estate Tool Box Pty Ltd [2021] FCA 809 is the foundation of one of Australia's most significant software copyright trilogies — a case that ultimately reached the High Court and redrew the boundaries of authorisation liability in Australian law.

The Trilogy in Context

The Campaigntrack litigation produced three major decisions:

1. [2021] FCA 809 — the primary judge's first instance decision (this article)

2. [2022] FCAFC 112 — the Full Federal Court's appeal decision, reversing key findings on authorisation

3. [2023] HCA 38 — the High Court's final resolution, partially restoring the primary judge's approach

Understanding the first instance decision is essential to appreciating why the appeal chain unfolded as it did, and what the final High Court ruling means for Australian businesses.

Background: DreamDesk and Toolbox

Campaigntrack Pty Ltd was the developer and owner of "DreamDesk," a cloud-based platform used by real estate agents to create and manage marketing materials. DreamDesk was a commercially significant product — it had been developed at considerable expense and represented a real competitive advantage for Campaigntrack in the real estate technology market.

The respondents — including Real Estate Tool Box Pty Ltd, Biggin & Scott Corporate Pty Ltd, Dream Desk Pty Ltd, Mr Semmens (the developer), Mr Stoner, Ms Bartels, and Mr Meissner — were involved in developing and deploying a competing system called "Toolbox." The core allegation was that Mr Semmens had copied DreamDesk's copyright works — including source code, database structures, and PDF generation components — when building Toolbox.

Direct Infringement: What the Court Found Against Mr Semmens

The primary judge's most significant finding was that Mr Semmens had directly infringed copyright in three categories of Campaigntrack's works:

• DreamDesk Source Code Works: Mr Semmens had reproduced portions of DreamDesk's source code in the Toolbox system. Source code and object code are "literary works" under the Copyright Act 1968 (Cth) — they attract full copyright protection from the moment they are written. Copying code from a competitor's system, even with modifications, is reproduction of a copyright work.

• Database and Table Works: The structure and content of DreamDesk's databases were reproduced in Toolbox. Database structures that reflect original creative choices in organisation and schema design can themselves be copyright-protected as literary works.

• PDF Works: Certain PDF generation components — including templates and output formats — were also reproduced. Where these represent original expression rather than purely functional output, they attract copyright protection.

Authorisation: The Primary Judge's Approach

While Mr Semmens was found to be a direct infringer, the primary judge largely dismissed the authorisation claims against the corporate respondents and individual executives. The reasoning was that the other parties had not sufficiently "sanctioned, approved or countenanced" Mr Semmens's copying — particularly given that Mr Stoner had instructed Mr Semmens not to breach third-party copyright.

This dismissal of the authorisation claims was the flashpoint for the appeal. The Full Federal Court reversed it in 2022 (finding the Biggin & Scott parties had authorised infringement), and the High Court then reversed the Full Court in 2023 (substantially restoring the primary judge's dismissal, while clarifying the authorisation test).

The ultimate High Court holding was that authorisation requires something more than knowledge that infringement might occur — the alleged authoriser must have sanctioned or countenanced the specific infringing acts. A general instruction not to copy, given in good faith, carries genuine legal weight.

Confidential Information and Contract Claims

The primary judge also addressed claims in confidence and contract. These claims — involving the misuse of confidential information embedded in the DreamDesk system — were addressed alongside the copyright claims. In complex software disputes, copyright and confidential information claims often travel together: the same code or database that is a copyright work may also constitute trade secret or confidential information. Businesses protecting their software should consider both avenues.

Why the First Instance Decision Still Matters

The trial judge's findings on direct infringement by Mr Semmens were never seriously challenged on appeal — both the Full Court and the High Court accepted that Mr Semmens had copied Campaigntrack's copyright works. This is the bedrock of the entire trilogy.

The primary decision is also important for the clarity with which it analyses software copyright — the categories of works involved, the evidence used to establish copying, and the way courts approach infringement in code-based disputes. For technology businesses and their legal advisers, the trial-level reasoning provides a practical framework for understanding what a court will look for in a software copyright case.

Strategic Takeaways

• Software is copyright from the moment it is written. Source code, database schemas, and template files are all literary works protected by Australian copyright law. There is no threshold of complexity or commercial value — protection is automatic.

• Copying is still copying, even with modifications. A developer who copies a competitor's code and then modifies it is still reproducing a substantial part of the original work. The test is whether the copied portion is qualitatively significant, not whether the final product looks different.

• The authorisation question is fact-intensive. What business principals knew, what instructions they gave, and what steps they took (or failed to take) when warning signs emerged are all material to liability. Detailed contemporaneous records of development decisions matter.

• Keep your own software records. To prove copyright infringement, you must establish that you own the copyright and that the defendant has reproduced a substantial part of it. Maintain version histories, commit logs, and records of authorship from the start of development.

• Consider confidential information claims alongside copyright. Where a competitor appears to have had access to your system, both copyright and breach of confidence claims should be assessed from the outset.

Conclusion

The Campaigntrack first instance decision laid the evidentiary and legal groundwork for a trilogy that ultimately reached the High Court. At its heart, the case is a clear and practical illustration of how copyright law operates in the software industry: code is protected, copying is infringement, and the courts take software piracy seriously regardless of the infringer's sophistication.
