Kernrechtsfrage
Whether the buyer's limitation period was interrupted by a conciliation request filed before an incompetent authority.
Extrahierter Entscheid
Yes. A conciliation request interrupts limitation even if the authority lacks subject-matter competence, and Art. 63 CPC applies to subject-matter as well as local competence.
Extrahierte Begründung
Filing creates lis pendens for private-law time limits. If the action is later withdrawn because the court lacks competence and refiled within one month, the original filing date remains relevant. The wording of Art. 63 CPC is not limited to territorial competence.
