Question juridique clé
Whether the appellant had a right to renewal of a residence permit under Art. 42 LEtr despite separation from his Swiss spouse.
Solution extraite
No right existed because the spouses no longer lived in a common household and the marriage could no longer be relied upon for renewal.
Motifs extraits
Art. 42 LEtr requires a common household. The separation had lasted well over a year, with no realistic prospect of resuming cohabitation, so the statutory condition was not met.
