Kernrechtsfrage
Whether the Zurich Commercial Court had international jurisdiction over the reinsurance claim under Art. 5(1)(b) Lugano Convention.
Extrahierter Entscheid
The place of performance is the reinsurer's seat, because the characteristic performance in reinsurance is the assumption of risk and permanent readiness to pay, so jurisdiction lies there.
Extrahierte Begründung
For service contracts under Art. 5(1)(b) LugÜ, jurisdiction is determined autonomously by the place where the characteristic service is chiefly performed. In reinsurance, the insurer's payment obligation is not the main service; the main service is risk assumption and maintenance of coverage, usually at the reinsurer's seat.
