What Works in Human Rights Institutions?

Since 1993, the United Nations has promoted national human rights institutions (NHRIs); these have spread to almost 120 countries. We assess what makes NHRIs effective, using quantitative and qualitative methods. We find that formal institutional safeguards contribute greatly to NHRI efficacy even in authoritarian and transition regimes. Complaint-handling mandates are particularly useful because they help NHRIs build broad bases of support. Our findings show how international organizations can wield great influence with soft tools such as recommendations and peer-review mechanisms
