Lessons learned from other review mechanisms on their operation and transition to a next phase: experiences collected in transitions by other peer review mechanisms: Document CAC/COSP/IRG/2023/8 (Parts 1 and 2)

The present note contains a review of the experiences collected in six peer review mechanisms in relation to their transition from initial to follow-up review phases, as well as other institutional reforms and lessons learned. The note should be read together with its addendum (CAC/COSP/IRG/2023/8/Add.1), which contains a review of nine possible dimensions of changes to peer review mechanisms, based on the transitions that the mechanisms underwent. The concluding summary in the addendum to the present note highlights common trends that States parties may wish to take into account in their design of the next phase of the Mechanism for the Review of Implementation of the United Nations Convention against Corruption, while ensuring that the Mechanism remains practically relevant and manageable and that the principles of transparency, efficiency, non-intrusiveness, inclusiveness and impartiality remain cornerstones of the exercise.
