Abstract: In the past decades, the public procurement system in Kenya has undergone significant developments. From being a system with no regulations in the 1960s, and a system regulated by Treasury Circulars in the 1970s, 1980s and 1990s, the introduction of the Public Procurement and Disposal Act (PPDA) of 2005 and the Procurement Regulations of 2006 has introduced new standards for public procurement in Kenya. As a result, ethical supply chain management is becoming a mainstream business practice in public sector in Kenya. Ethics in Public procurement provide advice and guidance to buying organizations on how to develop ethical purchasing practices in their supply chains (Arkingstall 1994). Although intended primarily for buyers, this guidance applies equally to anyone who has responsibility for managing the supply of goods or services from an external source. It has become essential for public organizations to have an ethical policy or code of conduct in procurement functions (Amstrong and Sweeney 2004). The Chartered Institute of Purchasing and Supply (CIPS) believes that public entities should universally apply the practice set out (as laws, regulations, policies and procedures) and should encourage all cadre of organizations to include good ethical business practices in all areas of their work. In this case, organizations should also involve all stakeholders in this process. It is vital that organization’s management visibly endorses procurement ethical policy.
