Key legal question
Which law governs interpretation of the forum-selection clause in the assignment agreement under Art. 17 aLugÜ?
Extracted holding
Where the form and the parties' basic agreement on a forum clause are not disputed, interpretation of that clause is governed by the lex causae chosen by the parties.
Extracted reasoning
The court held that the lower court wrongly applied Swiss interpretive rules. Because the assignment agreement contained an express Spanish choice of law and expressly provided for interpretation under Spanish law, the clause had to be construed under Spanish law.
