Questão jurídica principal
Whether the federal administrative appeal was admissible despite the cantonal court's non-entry decision

The appeal was inadmissible because no enforceable right to the requested residence permit existed.
Fundamentação extraída
Federal review of the cantonal court's refusal to enter depends on whether the asserted legal entitlement actually exists; here no entitlement followed from the asserted legal bases.
