Before the Tribunal, following its Judgment Johnson UNDT/2011/144, as confirmed by the Appeals Tribunal in Johnson 2012-UNAT-240, the Respondent does not contest anymore that the Applicant by using her foreign tax credit paid as a matter of fact part of the taxes due. The Respondent nevertheless refuses to reimburse to the Applicant the staff assessment deductions made, which the latter contests. The Tribunal finds in favor of the Applicant and orders the Administration to carry out a new calculation of the 2010 staff assessment deductions that ought to be reimbursed to her.
