Question juridique clé
Whether the public law appeal was admissible in an immigration case involving a residence permit under Art. 50 LEtr.
Solution extraite
The appeal in public law was admissible because the asserted entitlement under Art. 50 LEtr had to be examined on the merits.
Motifs extraits
Although no right followed from Art. 42 or 49 LEtr after the end of the marriage, Art. 50 LEtr could still confer a right, so the exception in Art. 83 let. c ch. 2 LTF did not bar review.
