Key legal question
Whether the ten-year expulsion was proportionate under the circumstances, including family life and seriousness of the drug offenses.
Extracted holding
The balancing of interests was not unconstitutional; the public interest in expulsion outweighed the private interest in remaining in Switzerland.
Extracted reasoning
The court relied on the seriousness of the offences, the sentence imposed, and the lower courts' assessment of family circumstances, and held that this followed established case law.
