Why this matter warrants attention
The court declared the appeal deserted due to insufficient technical grounds and the inclusion of fabricated case law. It did not impose formal professional sanctions but ordered the notification of the attorney and the local Bar Association to promote responsible AI use in legal practice.
The court reasoned that the appellant failed to meet the procedural requirements of Article 260 of the CPCC, which mandates a concrete and reasoned critique of the judgment. The court determined that the reliance on non-existent citations rendered the brief insufficient. Regarding the potential use of AI, the court reasoned that formal sanctions were inappropriate under current procedural rules and preferred an educational, collaborative approach to encourage ethical technology use.
Argentine appellate courts are notifying the bar even without a formal discipline order; the referral itself is the sanction.
