Why this matter is tracked
In a civil appeal regarding consumer protection and vehicle defects, the Chamber of Appeals of General Roca, Argentina, identified that counsel for both the plaintiff and the defendant DMX2 S.A. submitted numerous fabricated jurisprudential citations. The court conducted exhaustive searches and determined that multiple precedents attributed to the Superior Tribunal of Justice of Río Negro (STJ RN) and local Civil Chambers were nonexistent. Consequently, the court ordered that the work performed by the involved counsel be excluded from the calculation of legal fees and referred the matter to the local Bar Association (Colegio) for professional disciplinary review. The court emphasized that the integrity of legal research is fundamental to the judicial process and the administration of justice.
