Kernrechtsfrage
Whether the administrative law appeal was admissible against the revocation of the residence permit after expiry of the permit
Extrahierter Entscheid
The appeal was not admissible on that point because the permit had already expired before the appeal was filed, so there was no practical current interest.
Extrahierte Begründung
Even if administrative law appeal is generally available, the revocation had become devoid of practical effect once the authorization expired.
