1 The International Centre for Settlement of Investment Disputes was established pursuant to the 1965 Washington Convention. Convention on the Settlement of Investment Disputes Between States and Nationals of Other States, Mar. 18, 1965, 17 UST 1270, 575 UNTS 159 [hereinafter ICSID Convention].

8 According to ICSID, by 1996 there were some 1100 BITs, and more than 70% of them were concluded after 1987. See List of Parties to Bilateral Investment Treaties, at <http://www.worldbank.org/icsid/treaties/intro.htm>.

A more recent note asserts that the number of BITs now exceeds 2000. José, E. Alvarez, The Regulation of Foreign Direct Investment: Introduction, 42 Colum. J. Transnat’l L. 1, 2 (2003).Google Scholar

9 Between 1972 and 2003, ICSID settled eighty-eight cases. Still, almost the same number of cases—eighty-five—is currently pending before ICSID panels. This explosive increase is arguably indicative of the growing accessibility and appeal of ICSID dispute settlement procedures.

10 The term “international investment” has been construed very broadly in international practice, as encompassing a variety of cross-border transactions, involving transfer of money or effort from one state to the other, in exchange for an asset, with the expectation of returns or profits obtained in the territory of the host state. See, e.g., North American Free Trade Agreement, Dec. 17, 1992, Can.-Mex.-U.S., Art. 1139, 107 Stat. 2066, 32 ILM 289, 605 (1993) [hereinafter NAFTA] ;Joy Mining, supra note 5, para. 53; Tokios Tokeles v. Ukraine, Decision on Jurisdiction, ICSID No. ARB/02/18, para. 75 (Apr. 29, 2004).

11 See, e.g., NAFTA, supra note 10, Arts. 1102-1110; Agreement for the Promotion and Protection of Investments, May 16, 1997, Japan-H.K., Arts. 3-7, 36 ILM 1423 (1997); Agreement for the Promotion and Reciprocal Protection of Investments, July 4, 1989, Fr.-USSR, Arts. 3-5, 29 ILM 320 (1990); 2004 U.S. Model Bilateral Investment Treaty, Arts. 3-6, available at <http://www.ustr.gov> [hereinafter U.S. Model BIT],

14 See, e.g., NAFTA, supra note 10, Art. 1120; U.S. Model BIT, supra note 11, Art. 24(3). Some international instruments allow the investor to choose between several dispute settlement alternatives, which typically include both national and international judicial or arbitral procedures. See, e.g., Treaty Concerning the Encouragement and Reciprocal Protection of Investment, July 2, 1997, Jordan-U.S., Art. IX, S. Treaty Doc. No. 106-30, 36 ILM 1498 (1997); European Energy Charter, Dec. 12, 1994, Art. 26, 1994 O.J. (L 380) 24, 33 ILM 360 (1995). Finally, one should also note that numerous aspects of investment disputes might fall under the compulsory jurisdiction of domestic and international courts or tribunals (e.g., the ICJ in cases involving “optional clause” countries or those brought on the basis of a general compromissory clause). See, e.g., Elettronica Sicula S.p.A. (ELSI) (U.S. v. Italy), 1989 ICJ Rep.15 (July 20) [hereinafter ELSI]. This adds another potential avenue of jurisdictional competition between different investment courts and tribunals.

The Maffezini holding, however, was criticized and distinguished in some subsequent ICSID cases. Plama Consortium Ltd. v. Bulgaria, Decision on Jurisdiction, ICSID No. ARB/03/24, paras. 183-227 (Feb. 8, 2005); Salini, supra note 6, paras. 115-19.

17 According to ICSID’s decision in SGS v. Pakistan, the claimant is normally free to characterize his claims as either national or international law claims. SGS v. Pakistan, supra note 3, 42 ILM at 1313, para. 145; see also Salini, supra note 6, para. 136.

18 Still, some degree of forum shopping might be healthy, as it increases the likelihood that the parties will find a proper and competent forum to adjudicate their dispute, and places competitive pressures on courts to improve their procedures. For discussion, see Shany, Yuval, The Competing Jurisdictions of International Courts and Tribunals 144–45 (2003).Google Scholar

27 As it happened, the first-instance Swiss court dismissed the case on the basis of the contractual compromissory clause. Still, the appeals of SGS were rejected on the basis of state immunity arguments.

28 Agreement on the Promotion and Reciprocal Protection of Investments, July 11, 1995, Pak.-Switz., Art. 9, quoted in SGS v. Pakistan, supra note 3, 42 ILM at 1303, para. 80.

29 SGS v. Pakistan, supra note 3, Procedural Order No. 2 (Oct. 16, 2002). Some controversy surrounds the authority of ICSID tribunals to issue binding and enforceable provisional measures. Christoph, H. Schreuer, The ICSID convention: a commentary 757–62 (2001).Google Scholar Still, it may be argued that the comparable language used in Article 47 of the ICSID Convention and Article 41 of the ICJ Statute might render the ICJ’s LaGrand Judgment relevant for the purpose of ICSID as well. LaGrand (Ger. v. U.S.), Merits, 2001 ICJ Rep. 466, 506, para. 109 (June 27).

30 It may be noted that SGS argued, and the ICSID tribunal accepted, that it would not be able to bring its treaty claims in the context of the Pakistani proceedings. SGS v. Pakistan, 42 ILM at 1308, para. 119, & 1316, para. 154.

31 Id. at 1315-16, paras. 146-55.

32 Id. at 1316-18, paras. 156-62. Article 9 authorized ICSID to settle disputes “with respect to investments between a Contracting Party and an investor of the other Contracting Party.” See note 28 supra.

33 SGS v. Pakistan, supra note 3, 42 ILM at 1319-21, paras. 166-74. Article 11 provides: “Either Contracting Party shall constantly guarantee the observance of the commitments it has entered into with respect to the investments of the investors of the other Contracting Party.” Id. at 1318, para. 163. However, the tribunal held that the expansive construction advocated by SGS—incorporating within the BIT the fulfillment of contractual obligations—would result in the imposition of unreasonable procedural and substantive burdens on host states. The tribunal was not willing to assume, without clearer textual guidance, that this was the meaning intended by the drafters.

34 Agreement on the Promotion and Reciprocal Protection of Investments, Mar. 31, 1997, Phil.-Switz., Art. VIII, quoted in SGS v. Philippines, supra note 4, para. 34. Article VIII provides the investor with a choice between three dispute settlement procedures: national courts, an ICSID tribunal, and an ad hoc UNCITRAL arbitral tribunal.

35 SGS v. Philippines, supra note 4, paras. 52-56, 73-75.

36 Id., paras. 64, 85.

37 Id., paras. 65, 86. Article X(2) provides: “Each Contracting Party shall observe any obligation it has assumed with regard to specific investments in its territory by investors of the other Contracting Party.” Id., para. 34.

38 Id., paras. 66, 87. The chapeau to Article VIII covers disputes “with respect to investments between a Contracting Party and an investor of the other Contracting Party.”

39 Id., para. 60.

40 Id., paras. 116-28.

41 Id., paras. 125-26.

42 Id., para. 121 (referring in passing to some textual differences between the two clauses). Compare Swiss-Pakistani BIT, Art. 11, supra note 33, with Swiss-Philippine BIT, Art. X(2), supra note 37. The minor variations in the texts of the two clauses hardly explain the radically divergent outcomes of the two cases.

43 SGS v. Philippines, supra note 4, paras. 130-35. For a similar holding, see Salini Costruttori S.p.A. v. Morocco, Decision on Jurisdiction, ICSID No. ARB/00/4, 6 ICSID Rep. 400 (2004), 42 ILM 609, 623 (2003) (July 31, 2001).

44 SGS v. Philippines, supra note 4, para. 134. Both clauses invested the ICSID tribunal with jurisdiction over “disputes with respect to investments.”

45 Id., para. 154.

46 Id., paras. 139-43. It might also have been argued that the contractual compromissory clause constituted a valid choice of procedure on the part of the investor under Article VIII of the BIT.

47 Id., para. 155.

48 Id., paras. 162-63.

49 Id., para. 175. The majority grounded its decision to stay proceedings in its general powers under the ICSID Arbitration Rules and the Washington Convention to “make orders required for the conduct of the proceeding.” Id., para. 173.

50 SGS v. Philippines, supra note 4, Declaration of Antonio Crivellaro, paras. 2-7. Professor Crivellaro opined that differences in the identities of the parties to the BIT and the contract rendered the lex specialis principle inapplicable. Still, the third-party rights conferred by the BIT upon SGS enabled it to invoke the lex posteriori argument. Id., paras. 9-10. The lex posteriori argument, however, is problematic, given the renewal of the contract after the conclusion of the BIT. Cf. Pauwelyn, Joost, Bridging Fragmentation and Unity: International Law as a Universe of Inter-Connected Islands, 25 Mich. J. Int’l L. 903, 908 (2004)Google Scholar (the lex posteriori argument does not always work in international law).

51 SGS v. Philippines, Declaration of Prof. Crivellaro, supra note 50, para. 11.

52 Joy Mining, supra note 5, para. 63.

53 Id., paras. 77-82 (adopting the dicta of the SGS v. Pakistan tribunal on the importance of the nonprominent location of the umbrella clause in the BIT and on the illogicality of a construction transforming all contract claims into treaty claims). Notably, the language of the umbrella clause in the UK-Egypt BIT addressed in Joy Mining is virtually identical to that of the umbrella clause in the Swiss-Philippine BIT discussed in SGS v. Philippines. Agreement for the Promotion and Protection of Investments, June 11, 1975, Egypt-UK, Art. 2(2), Cmnd. 6141, 14 ILM 1470, 1471 (1975) (“Each Contracting Party shall observe any obligation it may have entered into with regard to investments of nationals or companies of the other Contracting Party.”). Hence, again, the difference in outcome must be explained in legal policy terms.

55 Salini, supra note 6, paras. 93-96.

56 Id., paras. 97-101.

57 Id., paras. 126-27. Indeed, Article 2(4) of the Italian-Jordanian BIT uses different language from that of the comparable provisions in the umbrella clauses of the Swiss-Philippine and Swiss-Pakistani BITs. Agreement on the Promotion and Protection of Investments, July 21, 1999, Italy-Jordan, Art. 2(4), quoted in id., para. 66 (“Each Contracting Parry shall create and maintain in its territory a legal framework apt to guarantee the investors the continuity of legal treatment, including the compliance, in good faith, of all undertakings assumed with regard to each specific investor.”).
