Kernrechtsfrage
Whether the appellant had passive standing as seller or successor debtor for warranty claims
Extrahierter Entscheid
No. The seller was the company named in the authentic deeds; the appellant was neither seller, successor, nor contractual debtor.
Extrahierte Begründung
The deeds clearly named A. SA as seller. Corporate personality cannot be disregarded absent economic domination and abusive invocation of separateness. Those conditions were not met, and dissolution did not justify suing the director instead of seeking re-registration of the company.
