就余留机制正在进行的工作而言，2020年将是举足轻重的一年，因为一些重要案件、特别是检察官诉拉特科·姆拉迪奇上诉案件和检察官诉约维察·斯塔尼希奇和弗兰科·西马托维奇审判案件届时将结案。20世纪最后10年对克罗地亚和波斯尼亚和黑塞哥维那的侵略行为的责任至今仍未得到追究，审结这些案件对于完成这项追责工作至关重要，特别是因为关键的塞尔维亚前总统斯洛博丹·米洛舍维奇一案不幸最终未作出判决。
When it comes to the Mechanism’s ongoing work, 2020 will be a significant year with the completion of important cases, in particular the appeal of the case Prosecutor v. Ratko Mladić and the Prosecutor v. Jovica Stanišić and Franko Simatović trial case. They are of the utmost importance to the legacy of accountability for aggression against Croatia and Bosnia and Herzegovina in the last decade of the twentieth century, especially because the crucial case against former Serbian President Slobodan Milošević unfortunately did not end up with a verdict.
