Questione giuridica chiave
Whether the appeal could be heard as a public-law appeal or subsidiary constitutional complaint despite lack of an enforceable residence-permit entitlement.
Decisione estratta
The appellant did not sufficiently substantiate any entitlement under federal law or the ECHR, so the court could not enter into the merits.
Motivazione estratta
Claims under Art. 50 AuG and Art. 8 ECHR were not properly reasoned; the complaint mostly attacked the facts and assessment of the lower court without meeting the strict admissibility and substantiation requirements.
