The Universal Periodic Review (UPR) is a process established to review adherence of all 192 member states to their human rights obligations set out in inter alia, the Universal Declaration of Human Rights, and various conventions, treaties, and human rights instruments. The review is conducted every four years by the UPR Working Group, which consists of the 47-members of the Human Rights Council. Iran was reviewed on 15 February 2010.
The State under review usually submits a self-assessment, or national report, of its human rights situation. Civil society members and the Office of the High Commissioner on Human Rights also compile their own reports. The State under review then participates in an interactive dialogue with the UPR Working Group during a three-hour meeting. The UN Member States then issue an outcome report containing a summary of the interaction as well as recommendations.
