Questão jurídica principal
Whether an appeal in public law matters was available against the refusal to renew the residence permit.
Decisão extraída
No. The applicant had no enforceable right to the permit under federal law or Article 8 ECHR because his children and former spouse did not have a sufficiently entrenched residence status.
Fundamentação extraída
Family life protection under Article 8 ECHR requires that the family member in Switzerland have a secure right of residence; mere residence permits are insufficient. No particularly intense private life ties were shown either.
