Questão jurídica principal
Whether summary eviction under Art. 257 ZPO was available because the facts were immediately provable and the legal position was clear.

Yes. The disputed receipt and content of the registered letters were immediately provable on the parties' submissions, and if the landlord's version was accepted the lease had clearly ended.
Fundamentação extraída
The tenants had acknowledged collecting the registered letters; the landlord produced the termination forms; under the pleadings principle the court could decide on the parties' pleadings and the legal consequences of a valid termination were clear.
