Kernrechtsfrage
Whether the appeal was admissible as a Verwaltungsgerichtsbeschwerde despite being styled as a constitutional complaint.
Extrahierter Entscheid
The filing had to be treated as a Verwaltungsgerichtsbeschwerde because the applicant had a statutory claim in principle under Art. 7 ANAG.
Extrahierte Begründung
Because the marriage formally still existed, the foreign spouse had an arguable entitlement to a residence permit; therefore administrative judicial review was available.
