Questione giuridica chiave
Whether the public-law appeal was admissible despite the immigration context
Decisione estratta
The appeal was admissible only to the extent the appellant plausibly invoked a potential entitlement to the requested permit; the new request for provisional admission was inadmissible.
Motivazione estratta
Because he was married to a Swiss citizen in an intact relationship, he could rely in principle on Art. 42 AuG and Art. 8 ECHR / Art. 13 BV. New claims and evidence on provisional admission raised for the first time before the Federal Court were barred by Art. 99 BGG.
