Kernrechtsfrage
Whether the lawyer had authority to file the inheritance action on behalf of X.
Extrahierter Entscheid
The court held that it was unnecessary to rely on a hypothetical earlier intention; it was sufficient that, by the time of judgment, X was represented by a legal guardian who could determine the lawyer's authority.
Extrahierte Begründung
Procedural capacity and the existence of representation must exist at judgment. After X became incapable and a guardian was appointed, only that guardian could ratify or contest the lawyer's powers; the cantonal court erred by focusing on X's earlier hypothetical will.
