Questão jurídica principal
Whether the appellant had an enforceable right to renewal of his residence permit based on family life with his Swiss son under Art. 8 ECHR.
Decisão extraída
The appellant had only a conditional claim under Art. 8 ECHR, but the requirements for renewal were not met because the father-son relationship was not particularly close economically or emotionally and his conduct in Switzerland was not faultless.
Fundamentação extraída
A non-custodial parent may invoke Art. 8 ECHR only exceptionally for residence purposes when there is a particularly intense relationship, practical impossibility of maintaining it from abroad, and faultless conduct; the findings showed irregular and limited contact, no maintenance payments, and prior criminal/fremdenpolizeiliche problems.
