This Practical Guide and the accompanying Study of State Engagement with International Human Rights Mechanisms seek to identify key ingredients for a well-functioning and efficient national mechanism for reporting and followup, drawing on different State practices, while not proposing a one-size-fitsall solution. The Guide provides practical advice on the critical elements that States need to consider when establishing or strengthening their national mechanism for reporting and follow-up, and illustrates this advice with examples of State practice. It is based on the more comprehensive Study of State Engagement with International Human Rights Mechanisms (HR/PUB/16/1/Add.1), which contains more detailed information on these practices.
