The aim of this article is to use a decolonial approach to interrogate Kenya's laws and policies that compel the admission and treatment of persons with psychosocial disabilities. Against the backdrop of the colonization of Africa, the article appraises the historical development of Kenyan mental health laws. It critically analyses domestic policies, legislation, court decisions and the Constitution as they apply to admission to healthcare facilities of persons with psychosocial disabilities and to the freedom to decide about treatment, in order to reveal the persistence of coloniality. It highlights gaps in the protection of equality, dignity and liberty. It also draws on pertinent provisions of the Convention on the Rights of Persons with Disabilities as a juridical method for translating a decolonial agenda into a normative framework. Ultimately, the article proposes a framework for decolonizing Kenya's mental health laws and policies.
