Questão jurídica principal
Whether the tenants validly waived rent-reduction and defect rights when signing the lease despite known renovation immissions.
Decisão extraída
No valid waiver was shown; the lease did not include an agreed compensation for the expected immissions.
Fundamentação extraída
The court held that the written lease and surrounding circumstances did not establish a contractual agreement excluding defect rights. The reserve clause did not imply a rent reduction for the immissions.
