Whether the termination for rent arrears under Art. 257d CO was valid despite later payments.
The payment deadline was not met in full; the landlord was therefore entitled to terminate the lease.
Within the 30-day warning period, only part of the claimed arrears was paid. The full amount demanded by the landlord on 20 April 2010 had not been settled by 21 May 2010, so the statutory preconditions for termination were met.
