Kernrechtsfrage
Whether the defendant’s delayed challenge of the dismissal constituted a breach causing damages to the plaintiff.
Extrahierter Entscheid
Yes. The mandatary breached the duty of diligent performance, and a timely challenge would have succeeded.
Extrahierte Begründung
Under mandate rules, the lawyer is liable if the missed procedural act would likely have led to success. Here the dismissal should have been contested successfully because the ordinary notice period applied.
