The single-tier administrative system with non-managing directors has been an option in Germany since the introduction of the Societas Europaea (SE). The particular relevance of the examination has been highlighted by recent business scandals and company crises, and also by the balance sheet scandals at the start of the millennium and the financial market crisis. Taking into account various legal systems, the liability of supervisory board members and non-managing directors is extensively discussed. From a comparative viewpoint, this publication aims to contribute to this legal discussion.
