The Applicant, a locally recruited staff member serving in Turkey, incurred significant medical expenses after being hospitalised on an emergency basis whilst on annual leave in Switzerland. UNHCR paid for those expenses and later informed the Applicant they would recover the difference between the cost of such treatment in Turkey and Switzerland from the Applicant, a decision challenged by the Applicant. UNDT dismissed the application. UNDT indicated that the conditions for reimbursement and the extent of coverage were governed by the UN Medical Insurance Plan (MIP) Rules, which the UNDT had accurately applied. UNDT held that the Administration was correct not to apply the stop-loss provision because it would have removed the limitation of the coverage to those reasonable and customary expenses incurred at the duty station and instead would have expanded the coverage worldwide, which was contrary to the terms of the MIP Rules. UNDT further rejected the Applicant’s argument that UNHCR had an obligation to reimburse him on account of an attestation he had received from human resources in UNHCR’s Ankara office to facilitate a visa for private travel as the said attestation had no legal authority to derogate from the MIP rules. The Applicant was also requesting disclosure of several documentation in which one of them included the document relevant to the calculation of “reasonable and customary expenses”. UNDT denied the Applicant’s motion on the grounds that the documents were not relevant.
