Von Geitz v Kelly & Ors; Von Geitz v Robertson & Ors, [2026] IECA 29

dismissal

In the Irish Court of Appeal, Allen J found self-represented plaintiff Juerg Von Geitz's submissions across two appeals contained unsupported propositions, wrong citations and 'a few non-existent cases' suggested to be AI hallucinations. He dismissed both appeals, affirmed the High Court's strike-out and Isaac Wunder orders, and stressed the litigant's own duty to verify AI output.

Conduct

A self-represented plaintiff's written submissions across two appeals were, per Allen J, 'littered with' unsupported propositions, wrong citations 'and a few non-existent cases'. At the appeal hearing it was suggested the non-existent cases were hallucinations generated by AI; the court stressed that verifying them remained the litigant's responsibility.
