Questione giuridica chiave
Whether the federal administrative law appeal was admissible despite no statutory entitlement to the residence permit.
Decisione estratta
The appeal was inadmissible because the applicants had no enforceable right to the requested permit under federal law or a treaty.
Motivazione estratta
Under Art. 100(1)(b) OG, review is excluded for permit refusals where no federal right exists. Art. 4 ANAG leaves admission to administrative discretion unless a special federal or treaty-based entitlement is shown; none was established.
