Key legal question
Whether the public-law appeal was admissible against revocation of a permanent residence permit
Extracted holding
The appeal was admissible because the case concerned revocation of an existing permanent residence permit, which would otherwise continue to have legal effects.
Extracted reasoning
Article 83(c)(2) BGG bars appeals only where no entitlement exists to the permit sought; revocation of a permanent permit is different, as the permit would still have legal effect absent revocation.
