Kernrechtsfrage
Whether the public-law appeal was admissible despite the immigration exceptions rule
Extrahierter Entscheid
The appeal was admissible because the applicants could invoke a potentially protected private-life claim under Article 8 ECHR, so the permit-renewal issue was not excluded at the outset.
Extrahierte Begründung
Given the long residence in Switzerland and signs of social integration, an enforceable claim could not be ruled out a priori; the existence of the substantive right had to be examined on the merits.
