AI Evidence Is Coming To Court: Authenticity, Manipulation, And Proof

Artificial intelligence is no longer just a business tool. It is increasingly part of the evidentiary landscape, and it is beginning to affect how disputes are run and how digital material is assessed in litigation. Emails drafted with AI assistance, AI-generated reports, deepfake-style audio or video, altered voice recordings and synthetic documents are now realistic possibilities in commercial disputes.

Australian courts are now confronting a practical question: can digital evidence still be trusted in the same way it once was?

For businesses, this is not an abstract concern. Many disputes turn on what was said in an email, what was agreed in a message thread, or what was captured in a recording. If those materials are challenged as manipulated or fabricated, the dispute can quickly shift away from the underlying commercial issue and into a technical contest about authenticity and proof. Understanding how courts approach authenticity is becoming critical.
