Questione giuridica chiave
Whether the constitutional/public-law appeal was sufficiently reasoned to permit review of the refusal to extend the residence permit.
Decisione estratta
The appeal did not sufficiently engage with the decisive reasoning of the cantonal decisions and therefore could not be examined on the merits.
Motivazione estratta
The appellant’s submissions did not show, in a legally relevant manner, how the lower decision violated the applicable provisions on residence permits and family reunification; the reasoning requirement of Art. 42 BGG was not met, so non-entry under Art. 108 BGG followed.
