ChatGPT and Copilot Data Could Be Used as Legal Evidence

Artificial Intelligence (AI) tools like ChatGPT and Copilot are transforming the way Australians work, communicate, and solve problems. But did you know that data generated by AI could potentially be used as evidence in legal proceedings?

As AI becomes more embedded in business operations—from customer service to internal documentation—its outputs are increasingly scrutinised in legal contexts. Whether you’re a business owner, IT manager, or legal professional, understanding how AI-generated content fits into the Australian legal landscape is essential.

AI Evidence: A New Frontier in Australian Law

In Australia, courts are beginning to grapple with the implications of generative AI. While ChatGPT itself is not a legal authority, its outputs can be considered part of the digital trail, especially when used in decision-making, communication, or documentation.

For example, if a business uses ChatGPT to draft internal policies or respond to customer complaints, those outputs may be discoverable in litigation. In civil cases, parties are often required to disclose relevant documents, and AI-generated content may fall under that umbrella.

But there’s a catch: not all AI-generated content is admissible. According to the Queensland Civil and Administrative Tribunal (QCAT) Guidelines, expert reports must not use generative AI without explicit permission from the court. If AI is used, the report must clearly state which parts were generated by AI and under what conditions. This highlights the growing need for transparency and accountability when using tools like ChatGPT in professional settings.

What Makes ChatGPT Data Legally Relevant?

ChatGPT doesn’t “know” facts in the way humans do. It generates responses by identifying patterns in large amounts of data and not by recalling specific truths or verified information. However, its outputs can still be relevant in legal cases if they:

• Demonstrate intent or decision-making: If someone uses ChatGPT to help write emails, contracts, or business documents, those outputs might reflect what the person or organisation intended at the time. In legal cases, this can be used to understand what decisions were made and why.
• Form part of a communication trail: In workplaces, especially in HR or customer service, AI-generated messages may become part of an official record. If something goes wrong, these messages might be reviewed to check for compliance, misconduct, or patterns of behaviour.
• Support or contradict testimony: ChatGPT’s outputs might be used as evidence to back up or dispute what someone claims. For instance, if someone says they didn’t approve a message or decision that an AI tool helped create.

Microsoft Copilot: A Powerful Tool with Legal Implications

Microsoft Copilot, which integrates AI into familiar tools like Word, Excel, and Teams, is rapidly becoming a staple in Australian workplaces. Its ability to summarise meetings, draft documents, and automate workflows is a game-changer—but it also raises legal considerations.

If Copilot is used to generate reports, emails, or meeting notes, those outputs may be subject to discovery in legal proceedings. For example, a Copilot-generated summary of a Teams meeting could be used to establish what was discussed or agreed upon. Businesses must treat these outputs as part of their official records and ensure they are stored, reviewed, and disclosed appropriately.

As with ChatGPT, the key is governance. Organisations should implement policies around Copilot usage, including:

• Clear documentation of when and how Copilot is used.
• Human oversight to verify the accuracy of AI-generated content.
• Training and awareness to ensure staff understand the legal risks.

Risks and Responsibilities for Australian Businesses

Using AI in your business isn’t inherently risky, but failing to manage its use properly can be. Here are some key considerations:

• Auditability: Can you trace how and why AI is being used in a particular decision or document?
• Disclosure: Are you prepared to disclose AI-generated content if required by a court?
• Accuracy: Have you reviewed and verified the outputs before relying on them?

A recent case involving a Melbourne law firm illustrates the risks. The firm submitted court documents containing fake citations generated by AI, leading to penalties and reputational damage. This underscores the importance of human oversight when using generative tools.

Best Practices for Using AI in a Legal-Safe Way

To stay on the right side of the law, consider these best practices:

1. Keep records: Log when and how AI is used, especially for business-critical tasks.
2. Review outputs: Never rely solely on AI-generated content without human oversight.
3. Disclose usage: If AI tools are used in reports or communications, be transparent about it.
4. Seek legal advice: If you’re unsure whether AI-generated content could be used in court, consult a legal professional.

The University of Sydney has also raised concerns about AI hallucinations and data misuse, reinforcing the need for caution when integrating these tools into business workflows.

AI is here to stay

Its role in legal proceedings is only going to grow. By understanding how AI-generated data can be used as evidence and by implementing smart governance, you can harness its power without exposing your business to unnecessary risk.
