Questione giuridica chiave
Whether the Federal Supreme Court could review the cantonal non-entry decision by way of public law appeal.
Decisione estratta
No. The administrative law appeal was unavailable, so the public law appeal could be examined only for formal denial of justice or other constitutional violations.
Motivazione estratta
The appellant had no federal or treaty-based entitlement to permit renewal, and the challenged decision concerned a review request based on cantonal procedural law.
