Kernrechtsfrage
Whether the public-law appeal was admissible against the revocation of the settlement permit and the alternative request for a residence permit.
Extrahierter Entscheid
The appeal was admissible only insofar as it challenged the revocation of the settlement permit; it was inadmissible as to the alternative request for a residence permit because no enforceable entitlement existed once the spouses no longer lived together.
Extrahierte Begründung
A settlement permit revocation is reviewable because a protected interest in its continuation exists. By contrast, under Art. 17(2) ANAG the spouse of a settled foreigner has an entitlement only while the spouses cohabit; that condition was undisputedly no longer met.
