Kernrechtsfrage
Whether the revocation of an EU/EFTA residence permit was lawful although the permit had originally been granted in error.
Extrahierter Entscheid
Yes. Article 23(1) VEP, in conjunction with Article 62 AuG, allows revocation when the permit conditions were never actually met; it does not matter whether the defect arose later or existed from the start.
Extrahierte Begründung
The purpose of Article 23(1) VEP is to ensure that no EU/EFTA permit remains in force without the necessary prerequisites. The court held that the provision covers both later-lacking and initially absent conditions, subject to proportionality and legitimate reliance interests.
