Question juridique clé
Whether the refusal to renew the residence permit was lawful despite the applicant's marriage to a Swiss citizen and family life in Switzerland.
Solution extraite
Yes. The criminal conviction constituted a ground for expulsion, which extinguished the derived right to a residence permit; the measure was proportionate.
Motifs extraits
The applicant had been sentenced to four years' imprisonment for a serious narcotics offence, well above the indicative threshold. Given the seriousness of the drug trafficking and recidivism risk, the public interest in protecting public order outweighed the private family interest.
