Kernrechtsfrage
Whether the subsidiary constitutional complaint was admissible against the refusal of a study residence permit.
Extrahierter Entscheid
The complaint was admissible only as a subsidiary constitutional complaint for alleged constitutional rights violations, because no statutory entitlement to the permit existed.
Extrahierte Begründung
Art. 27(1) LEtr is potestative and confers no enforceable right to a study permit; therefore ordinary review on the merits was unavailable.
