Question juridique clé
Whether the federal office's administrative law appeal was admissible against the cantonal judgment granting renewal of a residence permit
Solution extraite
The appeal was admissible because the federal office may challenge a cantonal final decision that allegedly grants a residence right contrary to federal law.
Motifs extraits
Although residence-permit refusals are generally excluded from administrative appeal when no federal right exists, the federal authority may appeal to ensure uniform application of federal law.
