Questão jurídica principal
Whether the administrative appeal against revocation of the residence permits was admissible
Decisão extraída
The appeal was admissible insofar as it challenged the cantonal judgment confirming revocation, but inadmissible as to the request to annul the first-instance decision directly.
Fundamentação extraída
Revocation decisions can be challenged by administrative-law appeal; however, the devolutive effect excludes direct challenge to the lower decision.
