Kernrechtsfrage
Whether the husband had his tax residence in Zurich in 2007
Extrahierter Entscheid
Yes. His center of life remained in Zurich despite weekday business activity in Prague.
Extrahierte Begründung
The court relied on the family home in Zurich, weekend returns there, lack of proof of a new permanent home in Czechia, and the absence of sufficiently changed circumstances in 2007. International cases require an overall assessment of personal and economic ties; special rules for inter-cantonal weekly commuters do not apply.
