Key legal question
Whether the applicant retained a right to renewal of his residence permit under Art. 7 ANAG and Art. 8 ECHR despite criminal convictions.
Extracted holding
The right to renewal was lost because the statutory expulsion ground was met and the proportionality balance favored removal.
Extracted reasoning
Repeated serious offending, including major narcotics trafficking, created a very strong public interest in exclusion that outweighed the family and private interests in remaining in Switzerland.
