1. Under Swiss law, when the meaning of a contractual clause is disputed, the judge seeks to determine the actual common intentions of the parties, without regard to incorrect statements or expressions used by the parties, whether by mistake or in order to conceal the true nature of the contract (Art. 18 para. 1 CO). When the actual common intentions of the parties cannot be established, the contract must be interpreted according to the requirements of good faith. The judge has to determine how a statement or an external manifestation by a party could have been reasonably understood by the other party, based on the particular circumstances of the case. The requirements of good faith tend to give preference to an objective approach. The emphasis is not so much on what a party may have meant but on how a reasonable person would have understood that party’s statements.
