Why this matter is tracked
In an appellate family law matter, the Arizona Court of Appeals vacated a superior court decree based on an unenforceable Rule 69 agreement due to a lack of mutual assent regarding marital property. During the appeal, the court identified that the appellee's opening brief contained substantial defects, including incomplete citations, unsupported legal premises, and fabricated quotations. The court explicitly noted that these defects suggested the use of artificial intelligence and warned that such failures to provide accurate legal authority violate Arizona Rule of Civil Appellate Procedure 13(a)(7). The court cautioned that future non-compliance with these rules may result in formal sanctions, though no monetary or professional sanctions were imposed in this specific instance.
