1. I concur with the conclusions of the Opinion of the Court both on the preliminary issues (jurisdiction and judicial propriety) and on most of the points belonging to the merits of the substantive issues involved. Nevertheless, not only have I some disagreements on certain specific points in the Opinion, but I have some serious reservations about the way the Court has proceeded in this case. While I acknowledge that the way in which the Court has proceeded with the present case has to a large extent been made inevitable under the somewhat extraordinary and unique circumstances of the case that are not always attributable to the responsibility of the Court, I feel it incumbent upon me to make my position clear, by pointing to some of the problematic aspects of the way in which the Court has proceeded in the present case.
2. The Court has reached its conclusions on the preliminary issues on jurisdiction and on judicial propriety of exercising this jurisdiction primarily on the basis of the statements put forward by the participants in the course of its written and oral proceedings. The reasons for the Court to arrive at these conclusions are set out in paragraphs 24-67. These, as such, raise no major disagreement on my part. However, I believe that the issue of jurisdiction and especially the issue of judicial propriety is a matter that the Court should examine, proprio motu if necessary, in order to ensure that it is not only right as a matter of law but also proper as a matter of judicial policy for the Court as a judicial body to exercise jurisdiction in the concrete context of the case. This means, at least to my mind, that the Court would be required to engage in an in-depth scrutiny of all aspects of the particular circumstances of the present case relevant to the consideration of the case, if necessary going beyond what has been argued by the participants. One of such aspects of the present case is the implication of the existence of a bilateral dispute in the subject-matter of the request for an advisory opinion.
3. The original Statute of the Permanent Court of International Justice contained no express provisions relating to advisory jurisdiction. Only the Covenant of the League of Nations, in its Article 14, stipulated that “[t]he Court may also give an advisory opinion upon any dispute or question referred to it by the Council or by the Assembly”. It was this provision that came to form the legal basis for the exercise of advisory function by the Permanent Court of International Justice.\
4. While the purport of this provision according to the intention of the founding fathers of the League does not appear to have been entirely clear nor unified, one of the points that clearly emerge from the legislative history of the Covenant is that the purpose of the advisory function of the Permanent Court consisted from the beginning in aiding the League in the peaceful settlement of a concrete dispute before the Council of the League, in particular in the context of the procedures provided for in Articles 12 to 16 of the Covenant.
5. When the Rules of Court were drafted in 1922 following the establishment of the Permanent Court, four articles (71-74) were consecrated to advisory procedure. They affirmed the “judicial character” of the advisory function of the new Court and paved the way for the later fuller assimilation of advisory to contentious procedure. Indeed, the Report of the Committee [of the Permanent Court of International Justice], appointed on 2 September 1927, stated as follows:
7. Against this background, the Permanent Court stated as follows to clarify its position:
8. When the International Court of Justice was reconstituted as the institutional successor to the Permanent Court of International Justice, and incorporated into the United Nations system as its principal judicial organ, no drastic change was introduced in the new Statute of the International Court of Justice relating to its functions or to its constitution in this respect. Since then, advisory function of the Court, as the secondary but important function of the Court, has been exercised by the Court in line with the course laid down by its predecessor, the Permanent Court of International Justice, in the days of the League as described above.
9. Given this background, and in light of the case law accumulated in the course of years since the establishment of the International Court of Justice on the questions of jurisdiction of the Court in advisory proceedings and of propriety of its exercise, it is my view that the Court is right in its conclusion in the present case that the existence of a dispute on a bilateral basis should not be a bar to the Court in giving the advisory opinion requested.
10. While the existence of a bilateral dispute thus should not exclude the Court from exercising jurisdiction in advisory proceedings as a matter of judicial propriety, however, it is my view that the existence of a bilateral dispute should be a factor to be taken into account by the Court in determining the extent to which, and the manner in which, the Court should exercise jurisdiction in such advisory proceedings. In this respect, I am of the view that the Court has drawn too facile an analogy between the present case and the past cases of advisory opinion and especially the case concerning Legal Consequences for States of the Continued Presence of South Africa in Namibia (South West Africa) notwithstanding Security Council Resolution 276 (1970), Advisory Opinion. Given the intricacies of the present case, I submit that this approach of applying the principles drawn from the past precedents automatically to the present situation is not quite warranted.
11. Especially in the Namibia case, the point in issue that formed the basis for the request for an advisory opinion was the “legal consequences . . . of the continued presence of South Africa in Namibia . . . notwithstanding Security Council resolution 276 (1970)”. In spite of the similarity in language in the formulation of the request, the basis for this request was very different from the present one. In the Namibia case, the Court was asked to give an opinion on the legal significance of the action taken by the United Nations in terminating the South African Mandate over South West Africa and its legal impact upon the status of South Africa in that territory. If there was a legal controversy or a dispute, it was precisely the one between the United Nations and the State concerned. By contrast, what is in issue in the present situation centres on a situation created by the action of Israel vis-à-vis Palestine in relation to the Occupied Palestinian Territory. It is undeniable that there is in this case an underlying legal controversy or a dispute between the parties directly involved in this situation, while at the same time, as the Court correctly points out, it concerns a matter between the United Nations and Israel since the legal interest of the United Nations is legitimately involved.
12. This of course is not to say that the Court should decline for this reason the exercise of jurisdiction in the present case. It does mean, however, that the question of judicial propriety should be examined taking into account this reality, and on the basis of the jurisprudence in more pertinent cases. I believe the closest to the present case probably is the Western Sahara, Advisory Opinion case, in the sense that there was in that case clearly an underlying legal controversy or a dispute between the parties involved. However, even that case does not offer a completely analogous precedent, from which the Court can draw its conclusion. In the Western Sahara case, the Court stated:
13. Thus, acknowledging the fact that in the present case there is this undeniable aspect of an underlying legal controversy or a dispute between the parties involved, and keeping this aspect clearly in mind, I wish to state that the critical test for judicial propriety in exercising jurisdiction of the Court, which it undoubtedly has, should lie, not in whether the request is related to a concrete legal controversy or dispute in existence, but in whether “to give a reply would have the effect of circumventing the principle that a State is not obliged to allow its disputes to be submitted to judicial settlement without its consent” (I.C.J. Reports 1975, p. 25, para. 33; emphasis added). To put it differently, the critical criterion for judicial propriety in the final analysis should lie in the Court seeing to it that giving a reply in the form of an advisory opinion on the subject-matter of the request should not be tantamount to adjudicating on the very subject-matter of the underlying concrete bilateral dispute that currently undoubtedly exists between Israel and Palestine.
14. The reasoning that I have offered above leads me to the following two conclusions. First, the fact that the present case contains an aspect of addressing a bilateral dispute should not prevent the Court from exercising its competence. Second, however, this fact should have certain important bearing on the whole proceedings that the Court is to conduct in the present case, in the sense that the Court in the present advisory proceedings should focus its task on offering its objective findings of law to the extent necessary and useful to the requesting organ, the General Assembly, in carrying out its functions relating to this question, rather than adjudicating on the subject-matter of the dispute between the parties concerned.
15. It should be recalled that, even when deciding to exercise its advisory function, this Court has consistently maintained the position that it should remain faithful to “the requirements of its judicial character”. Thus in the Western Sahara case the Court declared:
17. Article 68 of the Statute of the Court prescribes that “[i]n the exercise of its advisory functions the Court shall further be guided by the provisions of the present Statute which apply in contentious cases to the extent to which it recognizes them to be applicable.” Rules of Court in its Part IV (Arts. 102-109) elaborates this provision of the Statute. Particularly relevant in this context is Article 102, paragraph 3 of which provides that “[w]hen an advisory opinion is requested upon a legal question actually pending between two or more States, Article 31 of the Statute shall apply, as also the provision of these Rules concerning the application of that Article.”
18. In the Namibia case, South Africa made an application for the appointment of a judge ad hoc to sit in the present proceedings in accordance with this provision. Although the Court in its Order of 29 January 1971 decided to reject this application (I.C.J. Reports 1971, p. 12), it was met with well-argued dissenting views on this point (ibid., p. 308; p. 324). By contrast, in the Western Sahara case the Court took a different position. In response to a request by Morocco for the appointment of a judge ad hoc in accordance with Article 89 (i.e., present Art. 102) of the Rules of Court, the Court found that Morocco was entitled to choose a judge ad hoc in the proceedings. (A similar request by Mauritania on the other hand was rejected.) (I.C.J. Reports 1975, p. 6.)
19. The procedure for the appointment of a judge ad hoc is set in motion by the application of a State which claims that “the request for the advisory opinion relates to a legal question actually pending between two or more States” (Rules of Court, Art. 102). It is my view that in light of the precedents noted above, Israel in its special position in the present case would have been justified in making an application to choose a judge ad hoc. For whatever reason, Israel did not choose this course of action. It if had done so, the task of the Court in maintaining the essential requirement for fairness in the administration of justice would have been greatly enhanced. It goes without saying that such a course of action would have complicated the situation, due to the fact that the other party to this dispute, Palestine, is an entity which is not recognized as a State for the purpose of the Statute of the Court. What would happen then, if one of the parties directly interested is in a position of appointing a judge ad hoc, while the other is not. Fairness in the administration of justice could be questioned from this angle. While I do not propose to offer my own conclusion to this intractable but hypothetical problem, what I wish to point out is that this factor is one of the important aspects of the present case that could have been considered by the Court in deciding on the question of judicial propriety of whether, and if so how far, the Court should exercise its jurisdiction in the unique circumstances of this case.
20. Be that as it may, it is established that even in contentious proceedings the absence of one of the parties in itself does not deprive the Court of its jurisdiction to proceed (Statute of the Court, Art. 53), but that the Court has to maintain its fairness in the administration of justice as a court of justice. Thus, in relation to the question of the law to be proved and applied, the Court stated in the cases concerning Fisheries Jurisdiction as follows:
22. On this point of facts and information relating to the present case, it is undoubtedly true, as the present Opinion states, that
23. This, to my mind, would seem to be the case, in spite of the Court’s assertion that “Israel’s Written Statement, although limited to issues of jurisdiction and propriety, contained observations on other matters, including Israel’s concerns in terms of security, and was accompanied by corresponding annexes” (Advisory Opinion, para. 57). In fact my point would seem to be corroborated by what the present Opinion itself acknowledges in relation to the argument of Israel on this issue. Israel has argued that the wall’s sole purpose is to enable it effectively to combat terrorist attacks launched from the West Bank, or as the report of the Secretary-General puts it, “to halt infiltration into Israel from the central and northern West Bank” (Advisory Opinion, para. 80). However, the Court, in paragraph 137 of the Opinion, simply states that “from the material available to it, [it] is not convinced that the specific course Israel has chosen for the wall was necessary to attain its security objectives” (emphasis added). It seems clear to me that here the Court is in effect admitting the fact that elaborate material on this point from the Israeli side is not available, rather than engaging in a rebuttal of the arguments of Israel on
the basis of the material that might have been made available by Israel on this point. Again in paragraph 140 of the Opinion, the Court bases itself simply on “the material before it” to express its lack of conviction that “the construction of the wall along the route chosen was the only means to safeguard the interests of Israel against the peril which it has invoked as justification for that construction”.
24. In raising this point, it is not my purpose to dispute the factual accuracy of these assertions, or to question the conclusions arrived at on the basis of the documents and the material available to the Court. In fact it would seem reasonable to conclude on balance that the political, social, economic and humanitarian impacts of the construction of the wall, as substantiated by ample evidence supplied and documented in the course of the present proceedings, is such that the construction of the wall would constitute a violation of international obligations under various international instruments to which Israel is a party. Furthermore, these impacts are so overwhelming that I am ready to accept that no justification based on the “military exigencies”, even if fortified by substantiated facts, could conceivably constitute a valid basis for precluding the wrongfulness of the act on the basis of the stringent conditions of proportionality.
25. However, that is not the point. What is crucial is that the above samples of quotations from the present Opinion testify to my point that the Court, once deciding to exercise jurisdiction in this case, should be extremely careful not only in ensuring the objective fairness in the result, but in seeing to it that the Court is seen to maintain fairness throughout the proceedings, whatever the final conclusion that we come to may be in the end.
26. The question put to the Court for its advisory opinion is the specific question of “the legal consequences arising from the construction of the wall being built by Israel” (General Assembly resolution A/ES-10/L.16). It concerns only that specific act of Israel. Needless to say, however, the Israeli construction of the wall has not come about in a vacuum; it is a part, albeit an extremely important part, of the whole picture of the situation surrounding the peace in the Middle East with its long history.
27. Naturally, this does not alter the fact that the request for an advisory opinion is focussed on a specific question and that the Court should treat this question, and this question only, without expanding the scope of its enquiry into the bigger question relating to the peace in the Middle East, including issues relating to the “permanent status” of the territories involved. Nevertheless, from the viewpoint of getting to an objective truth concerning the specific question of the construction of the wall in its complete picture and of ensuring fairness in the administration of justice in this case which involves the element of a dispute between parties directly involved, it seems of cardinal importance that the Court examine this specific question assigned to the Court, keeping in balance the overall picture which has formed the entire background of the construction of the wall.
28. It has always been an undisputed premise of the peace in the Middle East that the twin principles of “[w]ithdrawal of Israel armed forces from territories occupied in the  conflict” and “[t]ermination of all claims or states of belligerency and respect for and acknowledgement of the sovereignty, territorial integrity and political independence of every State in the area and their right to live in peace within secure and recognized boundaries free from threats or acts of force” have to form the basis of the peace. Security Council resolution 242 (1967) has consecrated these principles in so many words. The “Roadmap”, endorsed by Security Council resolution 1515 (2003), is a blueprint for proceeding on the basis of these principles.
29. If the Court found that the construction of the wall would go counter to this principle by impeding and prejudicing the realization of the principles, especially in the context of the customary rule of “the inadmissibility of the acquisition of territory by war” (Advisory Opinion, para. 117), it should state this. At the same time, the Court should remind the General Assembly that this was a principle couched in the context of the twin set of principles, both of which would have to be realized, at any rate in the context of a peace in the Middle East, side by side with each other.
30. As observed above, Israel has argued that the wall’s sole purpose is to enable it effectively to combat terrorist attacks launched from the West Bank. In response to this, the Court has confined itself to stating that “[i]n the light of the material before it, the Court is not convinced that the construction of the wall along the route chosen was the only means to safeguard the interests of Israel against the peril which it has invoked as justification for that construction” (Advisory Opinion, para. 140). It is certainly understood that the material available has not included an elaboration on this point, and that in the absence of such material, the Court has found no other way for responding to this situation. It may also be accepted that this argument of Israel, even if acknowledged as true as far as the Israeli motives were concerned, would not be a sufficient ground for justifying the construction of the wall as it has actually been drawn up and implemented. As the Court has demonstrated with a high degree of persuasiveness, the construction of the wall would still constitute a breach of Israel’s obligations, inter alia, under the Hague Regulations Respecting the Laws and Customs of War on Land and the Fourth Geneva Convention relative to the Protection of Civilian Persons in Time of War, unless cogent justifications are advanced for precluding the wrongfulness of this act. But the important point is that an in-depth effort could have been made by the Court, proprio motu, to ascertain the validity of this argument on the basis of facts and law, and to present an objective picture surrounding the construction of the wall in its entirety, on the basis of which to assess the merits of the contention of Israel.
31. It is to my mind important in this context that the issue of mutual resort to indiscriminate violence against civilian population should be looked at. Without going into the question of what is the causal relationship between the tragic acts of mutual violence resorted to by each of the parties and the question of whether the so-called terrorist attacks by Palestinian suicide bombers against the Israeli civilian population should be blamed as constituting a good enough ground for justifying the construction of the wall, I believe it is beyond dispute that this tragic circle of indiscriminate violence perpetrated by both sides against innocent civilian population of each other is to be condemned and rejected as totally unacceptable. While it is true that this is not an issue expressly referred to as part of the specific question put to the Court, I believe it should only be natural that this factor be underlined as an important segment of the Opinion of the Court in dealing with the issue of the construction of the wall. This point to my mind is of particular relevance from the viewpoint that the Court should approach the subject-matter in a balanced way.
