(3) Issues of the award of interest have frequently arisen
in other tribunals, both in cases where the underlying claim
involved injury to private parties and where the injury was
to the State itself.605 The experience of the Iran-United
States Claims Tribunal is worth noting. In The Islamic
Republic of Iran v. The United States of America (Case
A–19), the Full Tribunal held that its general jurisdiction to
deal with claims included the power to award interest, but
it declined to lay down uniform standards for the award of
interest on the ground that this fell within the jurisdiction
of each Chamber and related “to the exercise … of the
discretion accorded to them in deciding each particular
case”.606 On the issue of principle the tribunal said:
Claims for interest are part of the compensation sought and do not
constitute a separate cause of action requiring their own independent jurisdictional grant. This Tribunal is required by [a]rticle V of the
Claims Settlement Declaration to decide claims “on the basis of respect
for law”. In doing so, it has regularly treated interest, where sought, as
forming an integral part of the “claim” which it has a duty to decide.
The Tribunal notes that the Chambers have been consistent in awarding
interest as “compensation for damages suffered due to delay in payment”. … Indeed, it is customary for arbitral tribunals to award interest
as part of an award for damages, notwithstanding the absence of any
express reference to interest in the compromis. Given that the power to
award interest is inherent in the Tribunal’s authority to decide claims,
the exclusion of such power could only be established by an express
provision in the Claims Settlement Declaration. No such provision exists. Consequently, the Tribunal concludes that it is clearly within its
power to award interest as compensation for damage suffered.607
The tribunal has awarded interest at a different and slightly lower rate in respect of intergovernmental claims.608
It has not awarded interest in certain cases, for example
where a lump-sum award was considered as reflecting full
compensation, or where other special circumstances pertained.609
(4) Decision 16 of the Governing Council of the United
Nations Compensation Commission deals with the question of interest. It provides:
1. Interest will be awarded from the date the loss occurred until
the date of payment, at a rate sufficient to compensate successful claimants for the loss of use of the principal amount of the award.
2. The methods of calculation and of payment of interest will be
considered by the Governing Council at the appropriate time.
604 See footnote 34 above. The Court accepted the French claim for
an interest rate of 6 per cent as fair, having regard to “the present financial situation of the world and … the conditions prevailing for public
loans”.
605 In the M/V “Saiga” case (see footnote 515 above), ITLOS awarded interest at different rates in respect of different categories of loss
(para. 173).

(see footnote 357 above), pp. 475–476, points out that the practice of
the three Chambers has not been entirely uniform.

608 See C. N. Brower and J. D. Brueschke, op. cit. (footnote 520
above), pp. 626–627, with references to the cases. The rate adopted was
10 per cent, as compared with 12 per cent for commercial claims.
609 See the detailed analysis of Chamber Three in McCollough and
Company, Inc. v. Ministry of Post, Telegraph and Telephone, Iran-U.S.
C.T.R., vol. 11, p. 3, at pp. 26–31 (1986).
3. Interest will be paid after the principal amount of awards.610
This provision combines a decision in principle in favour
of interest where necessary to compensate a claimant with
flexibility in terms of the application of that principle.
At the same time, interest, while a form of compensation,
is regarded as a secondary element, subordinated to the
principal amount of the claim.
(5) Awards of interest have also been envisaged by human rights courts and tribunals, even though the compensation practice of these bodies is relatively cautious and
the claims are almost always unliquidated. This is done,
for example, to protect the value of a damages award
payable by instalments over time.611
(6) In their more recent practice, national compensation
commissions and tribunals have also generally allowed
for interest in assessing compensation. However in certain
cases of partial lump-sum settlements, claims have been
expressly limited to the amount of the principal loss, on
the basis that with a limited fund to be distributed, claims
to principal should take priority.612 Some national court
decisions have also dealt with issues of interest under international law,613 although more often questions of interest are dealt with as part of the law of the forum.
(7) Although the trend of international decisions and
practice is towards greater availability of interest as an aspect of full reparation, an injured State has no automatic
entitlement to the payment of interest. The awarding of
interest depends on the circumstances of each case; in
particular, on whether an award of interest is necessary
in order to ensure full reparation. This approach is compatible with the tradition of various legal systems as well
as the practice of international tribunals.
(8) An aspect of the question of interest is the possible
award of compound interest. The general view of courts
and tribunals has been against the award of compound
interest, and this is true even of those tribunals which
hold claimants to be normally entitled to compensatory interest. For example, the Iran-United States Claims
Tribunal has consistently denied claims for compound
interest, including in cases where the claimant suffered
losses through compound interest charges on indebtedness associated with the claim. In R.J. Reynolds Tobacco
Co. v. The Government of the Islamic Republic of Iran,
the tribunal failed to find:
any special reasons for departing from international precedents
which normally do not allow the awarding of compound interest. As
noted by one authority, “[t]here are few rules within the scope of the
610 Awards of interest, decision of 18 December 1992 (S/
AC.26/1992/16).
611 See, e.g., the Velásquez Rodríguez, Compensatory Damages case
(footnote 516 above), para. 57. See also Papamichalopoulos (footnote 515 above), para. 39, where interest was payable only in respect of
the pecuniary damage awarded. See further D. Shelton, op. cit. (footnote 521 above), pp. 270–272.

United Kingdom and China (footnote 551 above).
