The new practice direction, signed by High Court President David Barniville, comes into force on 1 September and applies to all civil proceedings before the High Court. “GenAI Tools may also generate incorrect legal propositions or inaccurately summarise genuine sources,” a document on the High Court directions said. Under the new rules, anyone responsible for court documents must independently verify any material generated with AI before it is used in proceedings. The move follows several recent cases in which Irish judges expressed concern about the use of artificial intelligence in court proceedings. Separately, in October last year, High Court judge Mary Rose Gearty raised concerns after a litigant admitted using an AI tool to prepare court documents in proceedings involving an anonymity order.
