Questão jurídica principal
Whether the validity of the tenancy notice could be examined in BMM proceedings only as a preliminary question
Decisão extraída
Yes. The validity of the notice could be reviewed only incidentally because the rent-reduction and extension claims depended on it.
Fundamentação extraída
Art. 29 BMM covered rent and extension matters; the notice question had to be decided as a prerequisite, without res judicata effect.
