The Supreme Court dismissed a self-represented applicant’s leave applications, which relied on authorities it identified as hallucinations of a generative AI application, and ordered costs against her.
In Chen v Goodmore Investments Ltd and Tawa [2026] NZSC 40, a self-represented applicant’s submissions relied on fabricated case law and mischaracterised real authorities, which the Supreme Court identified as hallucinations of a generative AI application. The Court dismissed her applications for leave to appeal, a stay and new evidence, and ordered costs against her. It repeated its warning that such conduct could, in serious cases, amount to contempt or obstruction of justice.
