This article describes the current situation in the emerging integrated system of the European Community, focusing on the potential conflict between Community rules on the freedom of establishment and national conflict-of-law rules relating to companies. In the first part, I shall outline the relevant provisions of EC law and the two conflict-of-law concepts presently exhibited in the national laws of the Member States. In the second part, I shall discuss three cases in which the European Court of Justice recently addressed this subject. In the third part, I shall analyze the impact of the Court's opinions, and finally outline options for future legislative and other action.
