What happened in this matter?
The TSJ Gran Canaria identified that counsel for the appellant submitted a filing containing multiple fabricated case law citations and a non-existent doctrinal report.

Why this matter is tracked
In an appeal against an acquittal for sexual assault, the TSJ Gran Canaria identified that the appellant's counsel included numerous fabricated legal citations and doctrinal references in their filing. The court specifically noted that the appellant attributed passages to STS 494/2020 and STS 104/2019 that do not exist in those rulings, and cited a non-existent 2019 CGPJ report. The court characterized this as a recurring practice of relying on unverified content suggested by an AI algorithm, labeling the counsel's conduct as negligent. The court ultimately dismissed the appeal, finding the lower court's acquittal well-reasoned and the appellant's arguments, supported by the fabricated citations, insufficient to overturn the judgment.
