A. Introduction International commercial disputes, resulting from the failure of cross-border business transactions, are no new phenomena at all. However, the mere number of disputes between at least two different 1 business actors either residing in different states or disputing over events having taken place or having effects that occur in a state different to the forum state have been increasing for the last decades. 2 As the markets for goods and services have been globalizing successively-with the invention and, then, triumphal march of the internet marketplace as the latest and, of course, most revolutionary development-not only big but also so-called small and medium-sized businesses (SMB) are keeping pace. And, so do legal conflicts that arise, for example, in cases where one fails to perform a commercial contract or where a certain product causes mass injuries in different countries-just to name a few relevant constellations.
