The activities of Muslims for Human Rights (MUHURI), a civil society organization (CSO) based in Mombasa, Kenya, demonstrate the significant role budget transparency plays in improving accountability. MUHURI’s work also shows how public engagement in the budget process can strengthen oversight and lead to improved public service delivery. At the same time, MUHURI’s impact has been restricted by the lack of a Freedom of Information (FOI) law in Kenya, along with other broad transparency challenges in the country.
