Hancox v Sutherland and Others is an employment appeal addressing procedural fairness and responsibility for AI-assisted filings. The September 17, 2026 judgment followed a preliminary hearing on July 29.[1]

AI-assisted submissions

The tribunal considered a 300-page argument generated with ChatGPT. It required litigants to check accuracy, relevance and compliance with procedure themselves; opponents cannot be made responsible for checking. AI assistance is not generally prohibited, but deficient checking can prompt judicial inquiry and possible sanctions.[1][2]

Procedural outcome

One ground concerning fair notice and opportunity to participate in the earlier strike-out proceedings was reasonably arguable and could proceed to a full hearing. The tribunal rejected the attempt to add another ground and made case-management directions. The judgment does not finally resolve the underlying employment claim.[1]
