Abstract: This paper examines the integration of international human rights obligations into subnational legislative processes in federal systems, using disability rights lawmaking in Nigeria as an illustrative case. Despite Nigeria’s ratification of the Convention on the Rights of Persons with Disabilities (CRPD) and the enactment of federal disability legislation, significant disparities exist in the adoption, alignment, and enforcement of state-level laws. The study highlights the doctrinal pathways, institutional mechanisms, and political factors that influence subnational compliance, including legislative incorporation, judicial interpretation, cooperative federalism, and participatory lawmaking. It further analyzes substantive and institutional gaps in state legislation, revealing challenges such as limited enforcement capacity, weak civil society engagement, and uneven intergovernmental coordination. Drawing on these findings, the paper outlines treaty-consistent legislative drafting techniques, intergovernmental harmonization strategies, and participatory governance approaches that enhance democratic legitimacy and rights realization at the subnational level. The study contributes to the theoretical understanding of multilevel human rights governance, demonstrating that effective treaty implementation in federal systems requires more than formal ratification; it depends on coordinated legal, institutional, and civil society mechanisms that bridge the gap between international norms and practical outcomes. Finally, the paper identifies lessons for policy and legislative reform and proposes avenues for future research on the operationalization of human rights in decentralized governance contexts.
