Questão jurídica principal
Whether the termination given during pending lease-related proceedings was voidable under Art. 271a para. 1 let. d CO
Decisão extraída
The notice was presumptively abusive because it was served while lease-related proceedings were pending and the tenants had not acted in bad faith.
Fundamentação extraída
A tenant need not prove causality between the pending proceedings and the notice; during the protection period the termination is deemed abusive unless an exception applies.
