Questione giuridica chiave
Whether the federal appeal was admissible against the revocation of a settlement permit and which lower decisions could be challenged.
Decisione estratta
The appeal was admissible against the cantonal final judgment concerning the settlement permit, but not against the earlier cantonal and administrative decisions directly.
Motivazione estratta
A settlement permit still produces legal effects if not revoked, so its revocation can be reviewed under the federal public law appeal. However, only the cantonal final decision is directly challengeable before the Federal Supreme Court.
