A/HRC/41/CRP.2 people’s republic’ and ‘Luhansk people’s republic’ have yet to secure the full resumption of OHCHR operations in the territory they control.16 II. OHCHR methodology 19. This report is based on 179 in-depth interviews with individuals, including victims and witnesses of human rights violations and abuses. Information is generally obtained from victims, witnesses, relatives of victims and lawyers, site visits, Government representatives, civil society and other interlocutors, trial monitoring, as well as court documents, officials records, open-source and other relevant material. Findings are based on verified information collected from primary and secondary sources that are assessed as credible and reliable. Findings are included in the report where the “reasonable grounds” standard of proof is met, namely where, based on a body of verified information, an ordinarily prudent observer would have reasonable grounds to believe that the facts took place as described and, where legal conclusions are drawn, that these facts meet all the elements of a violation. 20. OHCHR applies the same due diligence and standard of proof when documenting conflict-related civilian casualties. OHCHR documents such casualties by consulting a broad range of sources and types of information that are evaluated based on credibility and reliability: victims and their relatives; witnesses; official records; open-source documents, photo and video materials; forensic records and reports; criminal investigation materials; court documents; public reports of the OSCE Special Monitoring Mission to Ukraine; reports by international and national non-Governmental organizations; public reports by law enforcement and military actors; data from medical facilities and local authorities; and other relevant and reliable materials. In some instances, documenting occurrences may take weeks or months before conclusions can be drawn, meaning that numbers on civilian casualties may be revised as more information becomes available. OHCHR attributes a civilian casualty to a particular party based on the geographic location where it occurred, the direction of fire, and the overall context surrounding the incident. 21. Consent is sought from sources on the use of information, ensuring confidentiality as appropriate, including an assessment of the risk of reprisals, in respect of OHCHR’s ‘do no harm’ principle. 22. While OHCHR cannot provide an exhaustive account of all human rights violations committed throughout Ukraine, it is able to obtain and verify information through a range of means according to its methodology, and bases its conclusions of patterns of human rights violations, abuses and harm on verified individual cases. 16 With the exception of field visits to document civilian casualties and conflict-related damage to civilian property in territory controlled by ‘Donetsk people’s republic’ which resumed during the reporting period. 7
