Key legal question
Whether Swiss/Vaud/Valais courts had jurisdiction over the payment claim and lien claim in an international dispute
Extracted holding
The Lugano Convention did not apply because only the plaintiff was domiciled in a contracting state; Valais courts were competent under LDIP and Swiss law.
Extracted reasoning
The place of performance for the money debt was the creditor's domicile in Valais under Art. 74 CO, and the lien claim was a real-property action for an immovable located in Valais under Art. 97 LDIP.
