Question juridique clé
Whether the federal appeal was admissible against the refusal to renew the residence permit
Solution extraite
The appeal was inadmissible because the case concerned non-renewal of an expired permit, and the appellant failed to show a legal entitlement to renewal.
Motifs extraits
For non-renewal of an expired residence permit, ordinary federal appeal lies only if federal or international law grants a claim. The appellant did not invoke or substantiate such a claim; art. 8 ECHR could help only in very exceptional circumstances, which were not shown.
