31. 行预咨委会回顾大会在其关于维持和平预算的决议中的一贯要求，即秘书长应确保迅速填补空缺职位(A/71/836，第 108 段)。行预咨委会还重申其观点，即应尽可能依据实际空缺率来确定预算空缺率。如果拟议的预算空缺率不同于编制预算时的实际空缺率，则应在有关预算文件中对所使用的空缺率作出明确的说明(A/70/742，第 45 段)。行预咨委会再次强调，应审查是否仍然需要已空缺超过两年或更久的员额，并在随后的拟议预算中提议保留(并重新说明理由)或裁撤这些员额(A/69/839，第 67 段；另见大会第 66/264 号决议)。
31. The Advisory Committee recalls the General Assembly’s request, expressed consistently in its resolutions on peacekeeping budgets, that the Secretary-General ensure that vacant posts be filled expeditiously (A/71/836, para. 108). The Committee also reiterates its view that budgeted vacancy rates should be based, as much as possible, on actual vacancy rates. In cases where the proposed budgeted rates differ from the actual rates at the time of budget preparation, clear justification should be provided in related budget documents for the rates used (A/70/742, para. 45). The Committee stresses again that the continuing requirement for posts that have been vacant for two years or longer should be reviewed and the posts either proposed for retention with rejustification or abolishment in subsequent budget proposals (A/69/839, para. 67; see also General Assembly resolution 66/264).
