Questão jurídica principal
Whether the notice of default of 4 May 2007 satisfied Art. 282 CO by expressly threatening termination.
Decisão extraída
No. A valid warning under Art. 282 CO must clearly state that the lease will be terminated if payment is not made in time; a mere reference to the contract clause was insufficient.
Fundamentação extraída
Art. 282 CO follows the same strict requirement as Art. 257d CO: the tenant or lessee must clearly understand that the landlord reserves the right to end the lease. The letter here contained no express termination threat, and the contractual reference did not replace it.
