Key legal question
Whether the public-law appeal was admissible and the subsidiary constitutional complaint could be entered into.
Extracted holding
The public-law appeal was admissible because a plausible statutory/international-law entitlement to renewal was invoked; the subsidiary constitutional complaint was inadmissible because it raised no additional claims.
Extracted reasoning
A spouse of a person with settlement permit can invoke Art. 43 AuG in principle. The subsidiary constitutional complaint adds nothing beyond the ordinary appeal against the permit refusal.
