Subject
The issue concerns whether a court may employ technical expertise to establish the damage element, the limits of investigation authority versus judicial fact‑finding, and how an appellate court should assess the plaintiff’s likelihood of success in the prior suit under Article (191/1) of the Code of Civil Procedure and in light of cassation decision 5274/2022.
Summary
- Article (191/1) confines appeals to the court of cassation to judgments issued by courts of appeal, requiring disregard of grounds aimed at first‑instance rulings. - Expertise is a technical tool to resolve technical questions or to assess the value of damage; it is not a substitute for judicial investigation to establish rights. An expert must not perform investigative tasks beyond their technical role; treating expertise as a means of proof for investigative facts contradicts cassation guidance (5274/2022). - The court must assess the seriousness of the plaintiff’s chance to win the prior action by weighing the evidence actually presented there; a mere existing claim does not justify deeming the plaintiff’s action lost without evaluating the submitted evidence as if timely filed. - Compensation for loss of opportunity is appropriate only if the court finds it likely the plaintiff would have prevailed had evidence been timely submitted; if the court deems defeat likely even with timely evidence, compensation should be denied. - The court of appeal is bound to follow the prior cassation decision under Article (202/1) of the Code of Civil Procedure; ordering an accounting expertise is improper where such a step conflicts with the cassation ruling and where the defendant’s evidence list contained no request for that expertise. - The evidentiary inquiry must focus on the defendant’s actual evidence in the prior suit, not on evidence the defendant ought to have presented, and must determine whether that evidence would undermine the plaintiff’s claim against her client.
