Key legal question
Whether the purchaser of the leased premises replaced the seller in the pending lease litigation under Art. 261 CO.
Extracted holding
Yes. The purchaser entered the pending proceedings in place of the seller because the dispute concerned the existence and prolongation of the lease, which continues to affect the tenancy after the transfer.
Extracted reasoning
When ownership changes during litigation, the buyer substitutes the seller if the pending case concerns a continuing tenancy relationship; the cantonal court should have taken the new ownership into account.
