Key legal question
Whether the appeal in public law matters was admissible despite the exclusion for discretionary immigration permits.
Extracted holding
Admissible only insofar as the appellant invoked a statutory or Convention-based entitlement to a permit; not admissible for the refusal of a purely discretionary permit.
Extracted reasoning
Claims under Art. 50 AuG and Art. 8 ECHR can found admissibility. By contrast, discretionary permits fall under the exclusion rule, and no legally protected interest was shown for a subsidiary constitutional complaint.
