Unlike many core human rights treaties, the Statelessness Conventions are among the most poorly ratified in the world. Orthodox scholarship on human rights treaties primarily focuses on post-ratification implementation and their impact on state conduct. While it is important to examine post-ratification compliance, understanding why states agree to ratify human rights treaties is as crucial. Ratification nudges states towards better human rights practices and serves as a gateway for the implementation of international norms. This chapter addresses this gap in scholarship by examining the ratification status of the Statelessness Conventions and the ratification process of the 1954 Statelessness Convention, together with key actors and their influence, by the Philippines, Southeast Asia’s first State Party to the treaty, and its subsequent accession to the 1961 Reduction of Statelessness Convention. Both rationalist and non-rationalist explanations account for ratifications. While rational explanations push states to ratify treaties, socializing liberal and constructivist-oriented explanations, for example, also drive states to commit to treaties. Multi-dimensional and multi-perspectival orientations should therefore inform how and why ratification or accession campaigns should be undertaken, and perhaps, even how treaties themselves should be designed. This analysis serves as a basis for broader theoretical reflections on persuading states to ratify human rights treaties.
