77 The ICJ in particular has rejected arguments relying on the motives of the states sponsoring a request for an advisory opinion, or on the alleged harmful consequences of an Advisory Opinion. See in particular: Kosovo, supra note 7, paras. 29ff; Wall, supra note 6, paras. 59–62. It has agreed in principle that a request may be rejected where it is a contentious dispute in disguise (Western Sahara, Advisory Opinion, 16 October 1975, [1975] ICJ Rep. 12, paras. 32–3). At the same time, this exception was ostensibly interpreted narrowly in the Wall Opinion, where the Court held (somewhat circularly) that the question concerned was not of a merely ‘bilateral’ nature, since it had ‘arisen during the proceedings of the General Assembly’. Wall, supra note 6, paras. 46–50. At times, requests for an advisory opinion have, however, been dismissed. See e.g., Status of Eastern Carelia, Advisory Opinion, PCIJ Rep Series B No 5, at 27–9 (see also infra); Compatibility of Draft Legislation with Article 8(2)(h) IACHR (requested by Costa Rica), Advisory Opinion OC-12/91, 6 December 1991, Inter-Am. Ct. H.R. (Ser. A) No 12 (1991), para. 28 (where the IACtHR dismissed a request that ‘could produce, under the guise of an advisory opinion, a determination of contentious matters not yet referred to the Court. . .’).
