Key legal question
Whether the public law appeal was admissible despite the lack of an enforceable right to a residence permit.
Extracted holding
The appeal was not admissible because no federal or conventional entitlement to the permit existed.
Extracted reasoning
The earlier marriage to a Swiss citizen did not create a current right; the family-life and private-life arguments under Article 8 ECHR did not establish an enforceable claim, and a mere arbitrariness complaint cannot create standing.
