B. The Special Rapporteur further calls upon the Government to undertake an independent and transparent investigation into the reported deaths in custody and other incidents leading to alleged violations of rights that took place during and after the protests. As of February 2021, there have been no independent and impartial investigations in compliance with international standards into the authorities’ response to the protests and the circumstances of the death in custody of those arrested in the context of the December 2017/January 2018 protests.41 The Government of the Islamic Republic of Iran has not undertaken an independent and transparent investigation into the reported deaths in custody and other incidents leading to alleged violations of rights that took place during and after the 2017 protests. Although the Islamic Republic of Iran has mechanisms able to receive complaints and conduct inspections within detention centres, there is no readily available information that might suggest that those mechanisms promptly and independently conduct investigations into human rights violations, including death in custody, or hold those responsible accountable. The Supervision and Inspection Board, established under the Law on Respect for Legitimate Freedoms and Safeguarding Citizen’s Rights, monitors the compliance of policies and conduct within the law and confronts those in breach. The Board’s missions include submitting “the complaints it receives to the relevant bodies and pursuing the investigation until it yields an outcome”, “deploying inspection groups to the bodies”, and “preparing reports on the implementation of laws in the country every three months and making them available to the public every three months.”42 The Supervision and Inspection Board also set up a database enabling victims and witnesses to submit their complaints. On the occasion of its 2019 Universal Periodic Review, the Islamic Republic of Iran stated that “the prosecutors, through judges stationed in prisons as well as the Secretariat of the Protection of Citizenship Rights and provincial supervisory boards, conduct regular inspections and investigate any reports or complaints” with regard to allegations of torture.43 There is no readily available information that might indicate that complaints have been investigated and adjudicated either by the Board or the Secretariat in an independent and impartial manner. Additionally, the Government of the Islamic Republic of Iran reported that the Citizenship Rights Watch Board conducts periodic inspections within prisons and detention centres. According to the Government the body has “received and handled 3,275 complaints and reports, through the complaint system, in relation with civil rights violations. Between 2015 and 2018, a number of 28,504 inspections were carried out to prosecutors' offices, prisons and detention centers.”44 There is no readily available information about the outcome of such inspections or 41 Amnesty International, https://www.amnesty.org/download/Documents/MDE1335462021ENGLISH.PDF See Executive By-law of Article 1(15) of the Law on Respect for Legitimate Freedoms and Safeguarding Citizens’ Rights. 43 Report of the Working Group on the Universal Periodic Review, February 2020, https://undocs.org/en/A/HRC/43/12/Add.1 44 National Report, UPR 2019, Islamic Republic of Iran, https://undocs.org/A/HRC/WG.6/34/IRN/1 42 5
