Dinesha Samararatne focuses on the process of ratification of the United Nations Convention on the Rights of Persons with Disabilities (CRPD 2006) in Sri Lanka. In particular, she is concerned with the following questions: why did Sri Lanka initially sign and then later ratify the CRPD? In what ways has ratification impacted on State action, civil society engagement and advocacy for the human rights of persons with disabilities? Has it influenced or led to the development of a ‘rights-based approach’ to disability among stakeholders? What does Sri Lanka’s experience suggest in terms of ratification of human rights treaties in general and specifically in terms of advancement of disability rights through international human rights treaty law? Samararatne considers these questions through an analysis of the process adopted by Sri Lanka in ratifying the CRPD.
