Although corporate governance codes have spread across the European Union and beyond, and are regularly revised and adapted to changing national and international expectations of investors and other stakeholders, some important questions have not yet been unanimously answered. Two of these ongoing debates are addressed in this chapter. First, where should the line be drawn between statutory provisions and corporate governance codes as an instrument of self-regulation? Second, what is the rationale behind the idea of independent directors? In particular, how should independence be understood in relation to board members: independent of the incumbent management and company or independent of a controlling shareholder? The chapter discusses both questions using the example of the German Corporate Governance Code.
