Kernrechtsfrage
Whether the complaint in public law matters was admissible for the requested residence permit and subsidiary constitutional complaint excluded.
Extrahierter Entscheid
The public-law complaint was admissible in principle because a legal entitlement to a permit was invoked; the subsidiary constitutional complaint was excluded.
Extrahierte Begründung
A claimed legal entitlement opens the public-law route under the Federal Supreme Court Act, while the subsidiary remedy is unavailable in that situation.
