Questione giuridica chiave
Whether the public-law appeal was admissible despite the expired residence permit and lack of an enforceable entitlement.
Decisione estratta
The appeal could be examined only to the extent the appellant plausibly invoked a possible entitlement; otherwise federal public-law review was excluded.
Motivazione estratta
Once the permit had expired, admissibility depended on a colorable entitlement. The court found such entitlement only in part, so it assessed the merits only within that scope.
