The Implementation Review Mechanism (IRM) is a peer review process that assists States parties to effectively
implement the Convention. In accordance with the terms of reference, each State party is reviewed by two peers - one from
the same regional group - which are selected by a drawing of lots at the beginning of each year of the review cycle. The functioning
and the performance of the IRM is guided and overseen by the Implementation
Review Group, an open-ended intergovernmental group of States parties which is a subsidiary body of the CoSP and was created
together with the IRM in Resolution 3/1.
Guiding principles of the Mechanism:
Transparent, efficient, non-intrusive, inclusive and impartial;
Non-adversarial and non-punitive, without any form of ranking;
Opportunities to share good practices and challenges;
Technical, promoting constructive collaboration; and
Complements existing international and regional review mechanisms.
The first cycle of the Review Mechanism started in 2010 and covers the chapters of the Convention on Criminalization and
Law Enforcement and International cooperation. The second cycle, which was launched in November 2015, covers the chapters
on Preventive measures and Asset recovery. UNODC is the secretariat of the Review Mechanism.
The purpose of the Implementation Review Mechanism is to assist States parties in their implementation of the Convention.
The Mechanism promotes the purposes of the Convention, provides the Conference of the States Parties with information on measures
taken by States parties in implementing the Convention and the difficulties encountered by them in doing so, and helps States
parties to identify and substantiate specific needs for technical assistance and to promote and facilitate the provision of
such assistance. In addition, the Mechanism promotes and facilitates international cooperation, provides the Conference with
information on successes, good practices and challenges of States parties in implementing and using the Convention, and promotes
and facilitates the exchange of information, practices and experiences gained in the implementation of the Convention.
The list of governmental experts - by country - is available here.
The Conference of the States parties decided that a comprehensive self-assessment checklist should be used as a tool to
facilitate the provision of information on the implementation of the Convention (resolution 3/1). Rather than using paper-based
questionnaires, UNODC has developed a user-friendly computer-based application to allow States to provide information on the
implementation of the Convention, the Omnibus Survey
Country pairings for each review cycle
In each review cycle, each State party must undergo review once, and must perform between one and three reviews of other
States. The timing of when each State is undergoing review, or acting as reviewing State, is determined by drawing of lots.
The schedule of country reviews and the list of reviewing and reviewed countries
for a given year are laid out in the country pairing tables for each review cycle:
