This policy briefing is based on a collaborative research effort comparing four international peer-review processes – the AU’s African Peer Review Mechanism (APRM), the UN’s Universal Periodic Review (UPR), the Organization for Economic Cooperation and Development’s (OECD) Anti-Bribery Convention Review (OECDA) and the Open Government Partnership (OGP) – undertaken by the Open Democracy Advice Centre in 2015. This comparison demonstrated not only the benefits for enhancing transparency if a country participates in the OGP, but also how political influences must be addressed when considering participation. The pitfalls of other peer-review processes should be avoided as the OGP develops further.
