Question juridique clé
Whether the payment order was invalid because the debtor lacked domicile in Gstaad and local jurisdiction was absent.
Solution extraite
The debtor was found to have his centre of life and thus his domicile in Gstaad; the payment order was valid.
Motifs extraits
The cantonal findings bound the Federal Court. The factual indicators supported a Swiss domicile, and the submitted novelties did not prove a clear foreign domicile or abusive use of Swiss enforcement powers.
