Key legal question
Whether the appeal in public law matters was admissible despite the permit dispute.
Extracted holding
The appeal was admissible because Article 50 LEtr could still confer a right to stay, so the case was not one where no right could arise from federal or international law.
Extracted reasoning
Although the divorce ended the right under Article 42 LEtr, the appellant relied on Article 50 LEtr; the existence of such a potential right sufficed for admissibility.
