Since the 1990s it is possible to witness, in the multiplication of inter- and transnational actors, an increasing diversity in international norm-making processes as well as a growing variation in enforcing these norms, generically labeled under the term “global governance.” The actions of these private, hybrid or intergovernmental actors on the global level are increasingly seen as equivalent to the exercise of political authority formerly reserved for the state. As in the domestic context, the exercise of such authority raises questions about the procedural guarantees that anyone affected by this action should enjoy. The Organization for Economic Cooperation and Development (OECD) has evaded intensive scholarly attention from the global governance perspective thus far, although by now it is evident that it strongly contributes to this phenomenon through its various activities. The OECD Guidelines for Multinational Enterprises (Guidelines) are but one area in which the OECD is said to assume global governance functions by strongly influencing corporate behavior.
