96 Report of the International Law Commission on the work of its fifty-third session (3) The primary obligation breached may also play an important role with respect to the form and extent of reparation. In particular, in cases of restitution not involving the return of persons, property or territory of the injured State, the notion of reverting to the status quo ante has to be applied having regard to the respective rights and competences of the States concerned. This may be the case, for example, where what is involved is a procedural obligation conditioning the exercise of the substantive powers of a State. Restitution in such cases should not give the injured State more than it would have been entitled to if the obligation had been performed.487 especially compensation, will be correspondingly more important. (4) The provision of each of the forms of reparation described in article 34 is subject to the conditions laid down in the articles which follow it in chapter II. This limitation is indicated by the phrase “in accordance with the provisions of this chapter”. It may also be affected by any valid election that may be made by the injured State as between different forms of reparation. For example, in most circumstances the injured State is entitled to elect to receive compensation rather than restitution. This element of choice is reflected in article 43. (b) does not involve a burden out of all proportion to the benefit deriving from restitution instead of compensation. (5) Concerns have sometimes been expressed that the principle of full reparation may lead to disproportionate and even crippling requirements so far as the responsible State is concerned. The issue is whether the principle of proportionality should be articulated as an aspect of the obligation to make full reparation. In these articles, proportionality is addressed in the context of each form of reparation, taking into account its specific character. Thus, restitution is excluded if it would involve a burden out of all proportion to the benefit gained by the injured State or other party.488 Compensation is limited to damage actually suffered as a result of the internationally wrongful act, and excludes damage which is indirect or remote.489 Satisfaction must “not be out of proportion to the injury”.490 Thus, each of the forms of reparation takes such considerations into account. (6) The forms of reparation dealt with in chapter II represent ways of giving effect to the underlying obligation of reparation set out in article 31. There are not, as it were, separate secondary obligations of restitution, compensation and satisfaction. Some flexibility is shown in practice in terms of the appropriateness of requiring one form of reparation rather than another, subject to the requirement of full reparation for the breach in accordance with article 31.491 To the extent that one form of reparation is dispensed with or is unavailable in the circumstances, others, 487 Thus, in the judgment in the LaGrand case (see footnote 119 above), ICJ indicated that a breach of the notification requirement in article 36 of the Vienna Convention on Consular Relations, leading to a severe penalty or prolonged detention, would require reconsideration of the fairness of the conviction “by taking account of the violation of the rights set forth in the Convention” (p. 514, para. 125). This would be a form of restitution which took into account the limited character of the rights in issue. 488 See article 35 (b) and commentary. 489 See article 31 and commentary. 490 See article 37, paragraph 3, and commentary. 491 For example, the Mélanie Lachenal case (UNRIAA, vol. XIII (Sales No. 64.V.3), p. 117, at pp. 130–131 (1954)), where compensation was accepted in lieu of restitution originally decided upon, the Franco-Italian Conciliation Commission having agreed that restitution Article 35. Restitution A State responsible for an internationally wrongful act is under an obligation to make restitution, that is, to re-establish the situation which existed before the wrongful act was committed, provided and to the extent that restitution: (a) is not materially impossible; Commentary (1) In accordance with article 34, restitution is the first of the forms of reparation available to a State injured by an internationally wrongful act. Restitution involves the re-establishment as far as possible of the situation which existed prior to the commission of the internationally wrongful act, to the extent that any changes that have occurred in that situation may be traced to that act. In its simplest form, this involves such conduct as the release of persons wrongly detained or the return of property wrongly seized. In other cases, restitution may be a more complex act. (2) The concept of restitution is not uniformly defined. According to one definition, restitution consists in reestablishing the status quo ante, i.e. the situation that existed prior to the occurrence of the wrongful act. Under another definition, restitution is the establishment or reestablishment of the situation that would have existed if the wrongful act had not been committed. The former definition is the narrower one; it does not extend to the compensation which may be due to the injured party for loss suffered, for example for loss of the use of goods wrongfully detained but subsequently returned. The latter definition absorbs into the concept of restitution other elements of full reparation and tends to conflate restitution as a form of reparation and the underlying obligation of reparation itself. Article 35 adopts the narrower definition which has the advantage of focusing on the assessment of a factual situation and of not requiring a hypothetical inquiry into what the situation would have been if the wrongful act had not been committed. Restitution in this narrow sense may of course have to be completed by compensation in order to ensure full reparation for the damage caused, as article 36 makes clear. (3) Nonetheless, because restitution most closely conforms to the general principle that the responsible State is bound to wipe out the legal and material consequences of its wrongful act by re-establishing the situation that would exist if that act had not been committed, it comes first among the forms of reparation. The primacy of restitution was confirmed by PCIJ in the Factory at Chorzów would require difficult internal procedures. See also paragraph (4) of the commentary to article 35.
