Six checks before AI research reaches your legal advice for in-house legal team

14 September 2026
AI citation-check checklist

A one-page checklist for in-house legal teams. Tool-neutral, in the order you would actually do them, built on the standard the Supreme Court and the Courts of New Zealand GenAI Guidelines have now set for lawyers.

In February 2026, the Supreme Court recorded that a litigant had cited authorities which appeared to have been hallucinated by an AI application. The Court warned that misuse of AI in legal proceedings has serious implications for the administration of justice and public confidence in the justice system, and that reliance on unverified citations may, in serious cases, amount to obstruction of justice or contempt. That litigant was self-represented, but the standard does not stop at the courtroom door. Rule 3 requires every lawyer, in-house counsel included, to act competently, and Rule 10.9 prohibits misleading or deceptive conduct, whatever the output in front of you is for.

Why it matters now

The risk is not only invented cases. In Jones, the Court identified citations that paired real case names with incorrect references, and four genuine cases were misused to support propositions they did not stand for. In May 2026, in Chen v Goodmore Investments (NZ) Ltd, the Supreme Court refused leave in four applications and recorded that many of the authorities relied on were irrelevant or did not exist, appearing to be hallucinations of a generative AI application. Costs of $2,500 were awarded to each respondent.

The professional exposure is not confined to litigators. The New Zealand Law Society’s guidance states that improper, negligent or incompetent use of generative AI could lead to a serious breach of the Conduct and Client Care Rules, including rule 3 (competence) and rule 10.9 (misleading and deceptive conduct). These duties apply to lawyers in-house as well as those appearing in court. The Courts of New Zealand GenAI Guidelines for Lawyers, issued on 7 December 2023, require lawyers using AI in court or tribunal proceedings to check any GenAI-provided information, including citations, for accuracy before relying on it. The same disciplines—verification, oversight and accountability—are equally relevant when AI-assisted research informs advice, contracts and board papers.
