This paper critically explores the IP approach adopted in Thailand with a particular emphasis on the role of the Independent Observers (IOs). The objectives are threefold: to examine the arrangements of Thailand’s IP approach and the IOs; to identify the contribution of the IP approach to the prevention of corruption in Thailand’s public procurement; and to investigate fundamental challenges the IP approach and the IOs face. The findings demonstrate that the IP approach is an effective means for ensuring citizen engagement in exacting public accountability and prevention of corruption in public procurement. However, they also highlight the key challenges of effective implementation of the approach including politicization of the IOs, the exclusion of the IOs in the drafting of Terms of Reference (TOR) and the officials’ misconceptions about the IOs.11 pagesapplication/pdfengThis work is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License.Corruption in public procurementIntegrity pactIndependent observersSocial accountabilityCivil societytext::journal::journal article10.1080/10999922.2021.1958563
