Key legal question
Whether the administrative appeal was admissible against refusal to renew the residence permit and removal order.
Extracted holding
The appeal was inadmissible because federal law granted no enforceable entitlement to the permit, and appeals against removal orders are excluded.
Extracted reasoning
No federal statute or specific treaty provision conferred a direct right to renewal. Article 8 ECHR did not help: no dependency relationship with adult sons, and the applicants had no sufficiently intensified private ties amounting to rooting in Switzerland.
