Questione giuridica chiave
Whether the public-law appeal against revocation of an existing residence permit was admissible
Decisione estratta
The appeal was admissible because it challenged the revocation of an already granted permit still in force if not revoked.
Motivazione estratta
A revocation interferes with an existing legal position and may be reviewed by the Federal Court under the ordinary public-law appeal, unlike a request for first-time admission.
