Questione giuridica chiave
Whether the public-law appeal was admissible despite the absence of a statutory or treaty right to a permit.
Decisione estratta
The appeal was admissible only to the extent the appellant plausibly invoked a possible right under Article 8 ECHR via his minor Swiss daughter; otherwise no admissible enforceable right existed.
Motivazione estratta
Article 50 AuG could not revive a right already extinguished by the 1997 divorce. A plausible claim based on family life with the youngest minor Swiss child sufficed only for admissibility, not for success on the merits.
