² The Polisario Front defines itself as a national liberation movement. It has previously been recognized by the UN General Assembly as ‘the representative of the people of the Western Sahara’. UNGA Res 34/37, ‘The Question of Western Sahara (21 November 1979) [7].

³ Negotiations on the region's final status indeed continue under UN auspices (coordinated in particular by the UN Secretary-General's Personal Envoy for Western Sahara). For the most recent UN resolutions, see (nn 104 and 105).

⁴ The SADR was proclaimed by the Polisario Front in 1976. It exercises control over some 20–25 per cent of the territory it claims. It is currently recognized as a State by some 45 UN Members and is a formal member of the African Union.

Already in 2016, Agrium—now Nutrien Ltd.—commissioned an audit which ultimately concluded that the company was ‘not causing or contributing to potential or actual negative human rights impacts in the Western Sahara’ through its supplier relationship with OCP/Phosboucraa.

³³ ‘A proceeding before a court of a State shall be considered to have been instituted against another State if that other State: … (b) is not named as a party to the proceeding but the proceeding in effect seeks to affect the property, rights, interests or activities of that other State.’ Note: the High Court did not take a position as to whether art 6(2)(b) UNCSI was reflective of customary international law, although it did cite Lord Sumption's position that the UNCSI represents ‘an authoritative statement … on the current understanding of the limits of state immunity in civil cases’ [77]. It may be noted that the UK Court of Appeal in Belhaj previously held that art 6(2)(b) UNCSI could not be considered reflective of a rule of customary international law (UK Court of Appeal (civil division), Belhaj, 30 October 2014, [2014] EWCA Civ 1394, [47]). The customary status of the provision (or lack thereof) was not, however, addressed explicitly in the subsequent judgment of the UK Supreme Court, albeit that Lord Mance did appear to raise doubts in this respect.

³⁶ It has been suggested that the High Court's approach may have been driven by ulterior motives. In particular, Angelet emphasizes the fact that South Africa had recognized the SADR as a sovereign State and suggests that the Court may have been reluctant to apply the rules of State immunity (or, possibly, the act of State doctrine (on which, see further below)) to the detriment of another sovereign State. N Angelet, ‘Immunity and the Exercise of Jurisdiction: Indirect Impleading and Exequatur’ in T Ruys and N Angelet (eds), The Cambridge Handbook on Immunities and International Law (Cambridge University Press) (forthcoming – on file with the author). Be that as it may, the recognition of the SADR by South Africa is not mentioned as a relevant factor in the Court's treatment of the State immunity defence (or the act of State defence). On a different note, it is observed that the recognition of the SADR by Panama did not prevent the Panamanian Court from concluding it had no jurisdiction in the case concerning the M/N Ultra Innovation (n 20).

³⁸ Famous cases include the seminal Schooner Exchange case before the US Supreme Court (1812) or the Parlement Belge in the UK (1879). A remnant of this case law can be found in section 11 of the South African Immunities Act (Act No 87, 1981) pertaining to Admiralty proceedings. At the same-time, relevant case-law pertaining to indirect impleading is not limited to actions involving ships and their cargo. The ILC Commentary also identifies several examples pertaining, for instance, to visiting forces, ammunitions and weapons and aircraft. Other cases concern proprietary or possessory rights over gold bars or monies (ibid 25).

³⁹ According to Angelet, for instance, ‘Article 6.2 is capable of encompassing a wide range of situations where the third State is not a party to the proceedings, beyond the hypothesis of ex parte proceedings regarding its rights or legal interests in the domestic legal order of the forum State’. Angelet (n 36).

Note: while Lord Sumption ‘would not altogether rule out the possibility that litigation between other parties might directly affect interests of a foreign state other than interests in property’, he stressed that ‘it is not easy to imagine such a case’.

⁵⁰ Case of the Monetary Gold Removed from Rome in 1943 (Italy v France, UK and USA) [1954] ICJ Rep 19, 32. Note also the contrast with the ICJ's Western Sahara Opinion, where the Court dismissed Spain's objection that it could not deliver the requested opinion absent Spain's consent, on the basis of the following reasoning: ‘[t]he issue between Morocco and Spain regarding Western Sahara is not one as to the legal status of the territory today, but one as to the rights of Morocco over it at the time of colonization. The settlement of this issue will not affect the rights of Spain today as the administering Power … ‘[T]he questions … do not … relate to a territorial dispute … between the interested parties … . The Court finds that the request for an opinion does not call for adjudication upon existing territorial rights or sovereignty over territory.’ Western Sahara (n 23) [42]–[43].

⁵¹ Case concerning East Timor (Portugal v Australia) [1995] ICJ Rep 90 [19]. Note, however, the Dissenting Opinion of Judge Skubiszewski ([1995] ICJ Rep [224]), who thought that the Court overextended the principle established in the Monetary Gold case. In essence, Judge Skubiszewski believed that the Court was not required to determine the rights and obligations of an absent third party (Indonesia), since those rights and obligations had been previously established by relevant UN resolutions. See eg at [85]: ‘By now taking judicial notice of the relevant United Nations decisions the Court does not adjudicate on any claims of Indonesia nor does it turn the interests of that country into the “very subject-matter of the dispute”.’

⁵² NM Cherry Blossom (n 22) [71].

⁵³ Interestingly, Angelet construes art 6(2)(b) UNSCI along the lines of the Monetary Gold principle. Angelet suggests that the crucial question is whether « l'appréciation de la légalité de l'acte de l'Etat tiers (ou de l'organisation internationale) constitue une simple préalable à sa décision sur une affaire qui relève par ailleurs de sa compétence naturelle, ou s'il s'agit au contraire de l'objet véritable du litige. » N Angelet, ‘Les juges belges face aux actes des organisations internationales’ in A Lagerwall (ed), Les juges belges face aux actes adoptés par les Etats étrangers et les organisations internationales – quel contrôle au regard du droit international ? (Larcier 2017) 27, [31]. See also Angelet (n 36) (‘Monetary Gold and the Ensuing Jurisprudence of the World Court May Also Assist in Delimitating the Immunity of the Absent State.’).

⁵⁶ Belhaj (n 30), [27] (Lord Mance): ‘In the courts below, Leggatt J … distinguished [East Timor and Monetary Gold] as cases about international jurisdiction, required in the case of the International Court to be based on consent, in contrast with which domestic courts exercise compulsory jurisdiction over those within their reach. That is correct as far as it goes, but states’ domestic jurisdiction also depends on consent in contexts where state immunity otherwise exists. The situation is therefore nuanced.’

⁵⁷ Ibid. [28].

⁵⁸ Confirming that such conduct is of a jure imperii character, see eg Fox and Webb (n 43) 404 (referring to ‘the exercise of regulatory control by the State as in … expropriation, nationalization, … regulation by the State of the exploitation of natural resources’); US District Court for the Central District of California, International Association of Machinists and Aerospace Workers v OPEC I 477 F.Supp.553 (C.D. CAL 1979), 18 September 1979 (regarding the control over oil resources as a sovereign function, and funding support for this position in UNGA Res 1803(XVII) according to which ‘a sovereign state has the sole power to control its natural resources’).

⁵⁹ In this sense: Fox and Webb (n 43) 404, 430–1; Yang, X, State Immunity in International Law (Cambridge University Press 2012) 298ffCrossRefGoogle Scholar. As both works observe, acts of expropriation or nationalization constitute an exercise of sovereign authority. The only country applying an exception denying immunity in respect of claims relating to expropriation of property contrary to international law is the United States (no such exception exists, for instance, in the South African Immunities Act). The scope of the US exception is moreover limited to the nationalization or expropriation of property without payment of the prompt, adequate and effective compensation required by international law, as well as takings which are arbitrary or discriminatory in nature. It also requires a territorial nexus with the US, in particular in the form of commercial activity in the US.

In a similar vein: UK Belhaj (n 30) [200] (Lord Sumption) (international law ‘does not require [States] to apply any particular limitation on their subject matter jurisdiction in litigation to which foreign states are not parties and in which they are not indirectly impleaded. The foreign act of state doctrine is at best permitted by international law.’).

⁶⁸ See eg, Case concerning the Barcelona Traction, Light and Power Company, Limited (Belgium v Spain), [1970] ICJ Rep 3 [93], and see the Separate Opinion of Judge Fitzmaurice ([1970] ICJ Rep. 64) [70] (referring to ‘an obligation to exercise moderation and restraint as to the extent of the jurisdiction assumed by its courts in cases having a foreign element’). See also Angelet (n 36), who suggests that the divergence between the common law and the civil law approach is perhaps overstated: ‘That the act of State doctrine originated in domestic law does not at all mean that common law courts could adjudicate cases typically falling within the realm of the doctrine, without violating international law. Rather, the application of the act of State doctrine pursuant to domestic law dispenses the courts from considering the international law limits to their powers.’

⁶⁹ This position is affirmed in particular in Jurisdictional Immunities of the State (Germany v Italy; Greece intervening) [2012] ICJ Rep 99 [94] (‘The Court concludes that, under customary international law as it presently stands, a State is not deprived of immunity by reason of the fact that it is accused of serious violations of international human rights law or the international law of armed conflict.’), [97] (‘[t]he Court concludes that even on the assumption that the proceedings … involved violations of jus cogens rules, the applicability of the customary international law on State immunity was not affected.’); ECtHR, Case of Jones and Others v The United Kingdom App Nos 34356/06 and 40528/06 (14 January 2014) [198].

⁷⁵ This is so because the scope of the ‘municipal act of State’ is often limited to acts of a State which take place or take effect within the territory of that State (eg Belhaj (n 30), [121]–[122](Lord Neuberger), [228] –[229] (Lord Sumption), and because of the unsettled status of the Western Sahara.

⁷⁶ For a detailed discussion of the various strands of the ‘act of State’ doctrine, compare the (slightly divergent) approaches of Lord Mance and Lord Neuberger, on the one hand, and Lord Sumption, on the other hand, in Belhaj. The ‘municipal act of state’ essentially entails that domestic courts will not adjudicate upon the lawfulness or validity of a State's sovereign acts (as opposed to acts of a private law character) within its own territory, irrespective of whether they constitute legislative or executive acts of the latter State.

It is noted, however, that the General Assembly has in two resolutions deplored Morocco's ‘occupation’ of Western Sahara, in resolutions in 1979 and 1980 (‘The Question of Western Sahara, UNGA Res 34/37 (21 November 1979) and UNGA Res 35/19 (11 November 1980)), albeit that it has not repeated such characterization in the 38 years since previous resolutions referred to the ‘continued occupation of Western Sahara by Morocco’.

Note: the Opinion appears to simultaneously take the view (1) that any exploitation of natural resources by Morocco in the Western Sahara is by definition contrary to international law and (2) that exploitation of natural resources in the Western Sahara must be for the benefit of the people of the Western Sahara and in accordance with their wishes—without, however, examining whether Morocco's activities in the Western Sahara meet the framework spelled out in the 2002 UN Legal Opinion. Apart from the internal inconsistency of the Legal Opinion, it may, however, be observed that, even if the situation in the Western Sahara is regarded as one of belligerent occupation, this does not make resource exploitation absolutely prohibited.

See in a similar vein the answer by Vice-President Mogherini on behalf of the European Commission in reaction to a parliamentary questions on the CJEU judgment in Case C-266/16, asserting that the ruling ‘did not impose any import ban on products originating in Western Sahara, but determined that at present the Association agreement contains no legal basis for granting tariff preferences to products coming from Western Sahara’.

¹²⁰ The obligation not ‘recognize as lawful a situation created by a serious breach’ of jus cogens is enshrined in art 41(2) of the ILC's Articles on Responsibility of States for Internationally Wrongful Acts (for text and commentaries, see (2001) YbILC Vol. II, Pt Two, 114–16. Among other things, the obligation of non-recognition—which operates on the intergovernmental plane—prevents States from entering into treaty relations with other States in respect of unlawfully acquired territory, or from sending diplomatic missions to regimes that result from a breach of jus cogens. The non-recognition principle also restricts the extent to which States can enter into economic and other forms of relationship concerning unlawfully acquired territory, albeit that some flexibility is introduced by the so-called Namibia exception, where non-recognition of certain acts would ultimately be to the detriment of the inhabitants of the territory concerned. An in-depth analysis of the obligation of non-recognition is beyond the scope of our analysis (see: Costelloe ibid; Crawford (n 116) 18–22, 31 ff). Suffice it to note that it implicitly follows from the ICJ's Jurisdictional Immunities case (n 61) that the obligation of non-recognition cannot override the rules of State immunity. The obligation of non-recognition does not feature in the cited judgments of the EU Courts pertaining to the Western Sahara.
