Questione giuridica chiave
Whether the federal appeal was admissible, including the challenge to the cantonal and administrative decisions.
Decisione estratta
The appeal was admissible as a public-law appeal against revocation of a still-effective residence permit, but the request to annul the first-instance administrative decision was inadmissible because of the devolutive effect of the cantonal appeal.
Motivazione estratta
The case concerned revocation of a residence permit that would otherwise still have effects; the appeal was timely and properly filed. However, only the cantonal judgment could be challenged before the Federal Court.
