This chapter, while acknowledging that there are certain differences and similarities in how the law treats standards development organizations (SDOs) that develop voluntary standards, offers a holistic analysis of the procedural principles introduced in the WTO, EU, and US regulatory frameworks, namely, transparency, openness/participation, consensus, impartiality, balance, effectiveness, relevance, coherence, coordination, concerns of developing countries, appeal, and access to standards, which this study collectively refers to as “due process” principles. This chapter further explores the relevance and suitability of these principles to the different types of standards bodies and identifies the shortcomings of each of the legal mechanisms with regard to ICT standardization. It concludes that these principles are formulated rather flexible and, to be effective, need further concretization by SDOs.
