[Case available at http://cisgw3.law.pace.edu/cases/00107cl.html].

Both parties‘ interpretations of Clause 5 of the Contract make sense to a certain extent. The Tribunal cannot locate a guide from the CISG - which both parties agreed to have as the governing law - to solve the problem. However, the Tribunal notes that Clause 5 is from the standard contract drafted by the [Seller]. According to the basic principle of contract interprettation - contra proferentem - if contract terms supplied by one party are unclear, an interpretation against that party shall be adopted.
