Kernrechtsfrage
Whether the public-law appeal was admissible against revocation of an establishment permit
Extrahierter Entscheid
The appeal was admissible because revocation of an establishment permit is not purely discretionary and the appellant had a principled right to maintain it.
Extrahierte Begründung
A revocation under Art. 9(4)(a) LSEE presupposes statutory grounds; additionally, the appellant had in principle a right to an establishment permit under Art. 7(1) second sentence LSEE after more than five years of marriage to a Swiss citizen.
