Key legal question
Whether the federal public-law appeal was admissible despite no entitlement under Art. 42 LEtr.
Extracted holding
The appeal was admissible because Art. 50 LEtr could still potentially confer a right to a residence permit.
Extracted reasoning
Although the marital union had ceased, the applicant invoked Art. 50 LEtr, so the bar of Art. 83 let. c ch. 2 LTF did not apply at the admissibility stage.
