Key legal question
Whether the refusal to renew the residence permit was lawful despite family ties and long residence in Switzerland.
Extracted holding
The permit refusal was lawful because the serious narcotics conviction triggered an expulsion ground, the public interest in removal prevailed, and the interference was proportionate.
Extracted reasoning
The appellant's conviction for a serious drug offense, together with prior traffic offenses, showed significant danger and heavy fault. Family life and the children's interests did not outweigh the public security interest, and the family's relocation to Macedonia was considered feasible.
