余留机制改进了核准一般临时人员职位变动情况的实证和文件编制程序，这些信息反映出预算期间逐步变化的所需业务资源。实证工作指导和支持了余留机制当前拟议预算的制定。虽然已尽一切努力确保目前的提议包含全部一般临时人员所需资源，但余留机制在调查、证人援助和保护以及审判活动等司法活动方面的任务具有不断变化的性质，因此可能不可避免地需要在执行核定预算的过程中改变一般临时人员的人员配置安排。
The Mechanism has improved the process of substantiation and documentation of approvals to changes in general temporary assistance positions that constitute progressive operational requirements in the course of a budget period. This substantiation has guided and supported the formulation of the current budget proposal of the Mechanism. While all efforts have been made to ensure that the current proposal constitutes the full general temporary assistance requirements, the evolving nature of the Mechanism’s mandate in terms of judicial activities, including investigations, witness assistance and protection and trial activity, inevitably may require changes to the general temporary assistance staffing posture in the course of the implementation of the approved budget.
