Kernrechtsfrage
Whether the appeal in public law matters was admissible despite the immigration decision.
Extrahierter Entscheid
The appeal was admissible because the applicant had a prima facie statutory residence claim under Art. 7 ANAG; the alleged abuse of rights concerned the merits, not admissibility.
Extrahierte Begründung
A foreign spouse of a Swiss citizen generally has a right to renewal. Whether that right is lost through an exception or abuse of rights is a substantive question.
