Question juridique clé
Admissibility of the appeal and scope of review
Solution extraite
The complaint was admissible insofar as it challenged the alleged lapse of the settlement permit; new requests and nova were inadmissible.
Motifs extraits
A settlement permit generally confers an unlimited right of residence, so Art. 83 BGG did not bar review. However, the Court limited the subject matter to the retention decision and excluded new factual allegations and evidence.
