12. 2020 年期间，COVID-19 大流行对余留机制计划应交付产出和活动产生了影响。这种影响包括法庭审理程序暂停，导致斯塔尼希奇和西马托维奇案的出示证据工作从 2020 年 3 月推迟到 9 月完成。此外，姆拉迪奇案的上诉程序不得不从2020 年 5 月推迟到 8 月，当时借助信息技术以及实体法庭基础设施的改进，上诉分庭 5 名法官中的 4 名能够远程参与。此外，由于与 COVID-19 有关的限制，例如辩方暂时无法进行调查任务，有多名被告人的图里纳博等人案的开庭时间从2020 年 6 月推迟到 10 月。这些变化影响了 2020 年方案执行情况，并影响了所有构成部分的工作。少数计划应交付产出，如对执行国的访问或向公众开放参观包括图书馆和档案馆在内的房地，由于疫情而无法完整执行。然而，由于通信基础设施的改善和对设施的改进，所有获授权的关键方案能够在全年持续执行，体现在卡布加先生被捕和确认奥古斯丁·比齐马纳死亡、远程管理执行国的援助请求和监测移交的案件等方面。
12. During 2020, the COVID-19 pandemic had an impact on the planned deliverables and activities of the Mechanism. The impact included a temporary suspension of court proceedings, resulting in the postponement of the completion of the presentation of evidence from March to September 2020 in the Stanišić and Simatović case. In addition, the appeal proceedings in the Mladić case had to be postponed from May until August 2020, when advances in information technology as well as physical courtroom infrastructure enabled the remote participation of four of the five judges of the Appeals Chamber. Furthermore, the commencement of the multi-accused Turinabo et al. case was delayed from June until October 2020 because of COVID-19-related restrictions, such as the temporary inability of the Defence to conduct its investigative missions. These changes had an impact on the programme performance in 2020 and affected the work of all components. A small number of planned deliverables, such as missions to enforcement States or physical access by the public to the premises, including libraries and archives, could not be implemented in their entirety owing to the pandemic. However, improved communications infrastructure and amendments to facilities enabled the continuous implementation of all key mandated programmes throughout the year, as was evidenced by, among other things, the arrest of Mr. Kabuga and the confirmation of the death of Augustin Bizimana, the remote management of requests for assistance from enforcement States and the monitoring of referred cases.
