4 Eritrea's Claim 19, Pensions, Memorial, filed by Eritrea on November 1, 2004, para. 1.4 [hereinafter ER Pensions Mem], contends that Eritrea paid pensions utilizing its own funds, and was then reimbursed by Ethiopia, rather than distributing funds provided by Ethiopia. This differs from the structure described in some documents in the record and from Ethiopia's description of the system. However, factual differences in this regard are not material and need not be resolved by the Commission.

19 Transcript of the Eritrea-Ethiopia Claims Commission Hearings of April 2005, Peace Palace, The Hague, at p. 181 (Apr. 5, 2005) [hereinafter Pensions Hearing Transcript]. It would not be unusual if Ethiopian legislation does not establish a legally enforceable, non-derogable right to receive a pension for past government service. Many countries’ laws leave the State the flexibility to modify, or even eliminate altogether, such pensions. O'Connell notes that “the right of British civil servants to pensions is not absolute.” Vol.1, state succession in municipal law and international law p. 470 (D.P.O'Connell ed., Cambridge 1967) [hereinafter O'Connell].

24 ER Pensions Mem, supra note 4, at para. 1.3, briefly refers to “an enormous windfall” to Ethiopia “at the expense of elderly Eritreans,” but it does not otherwise indicate a claim for unjust enrichment under international law or address the legal elements of such a claim.
