Les solutions juridiques risquent en conséquence de fortement varier d'un Etat membre à l'autre, et les parties pourraient être amenées à porter le litige devant le tribunal qui appliquera la loi qui leur serait la plus favorable, pratique désignée par l'expression "forum shopping".
Thus the risk that the solutions may vary from one Member State to another is important and the parties may be incited to chose to sue another party in the court whom they believe to apply the law which is the most favourable to them, a practice which is commonly designated by the term "forum shopping".
