Kernrechtsfrage
Admissibility of the public-law appeal against refusal of a student residence permit
Extrahierter Entscheid
The appellant had no substantive right to the permit and therefore could not challenge the merits; the appeal was only admissible, if at all, for formal procedural grievances.
Extrahierte Begründung
Without a federally protected entitlement, neither administrative-law appeal nor public-law appeal on the merits was available; only formal denial-of-justice complaints remained open.
