UNAT considered Mr Gakumba鈥檚 application for revision of judgment No. 2013-UNAT-387. UNAT held that it did not fulfil the statutory requirements and was seemingly disguised as an attempt to re-open the case. UNAT held that it would be manifestly unreasonable to submit that the UNDP Conversion Policy issued in 2010 could not be argued by the staff member in 2012 before the UNDT, or in 2013 before UNAT. UNAT held that no valid reason had been provided about the untimely submission of the application for revision. UNAT dismissed the application for revision.
