¹ The tests that have received the most attention thus far and will be considered in this discussion are: General Agreement on Tariffs and Trade (GATT 1947), in WTO, The Legal Texts: The Results of the Uruguay Round of Multilateral Trade Negotiations (2007) 423–493; (Legal Texts) arts XX and XXI; Agreement on the Application of Sanitary and Phytosanitary Measures (15 April 1994); Marrakesh Agreement Establishing the WTO (hereinafter WTO Agreement), Annex 1A, Legal Texts, 59–73, arts 2.2 and 5.6 (hereinafter SPS Agreement); Agreement on Technical Barriers to Trade (15 April 1994) WTO Agreement, Annex 1A, Legal Texts 121–143, arts 2.2 and 2.5 (hereinafter TBT Agreement); General Agreement on Trade in Services, WTO Agreement, Annex 1B, Legal Texts, 284–320, arts XIV and VI:4 (hereinafter GATS Agreement).

⁴ The newer SPS, TBT and GATS agreements have not yet been subjected to the same degree of judicial scrutiny as they have only been raised and considered relevant on a limited number of occasions. As such, the discussion relating to these agreements is similarly constrained. In particular, while the GATS jurisprudence will be discussed, it will not be considered as a separate necessity test to the one contained in the GATT due to the almost identical textual content and similar goals of the agreements (see n 134). Necessity under the TRIPs Agreement will not be discussed.

⁹ VCLT art 31. This method of interpretation has been accepted by the adjudicating bodies on a number of occasions which have stated that this provision constitutes ‘customary rules of interpretation of public international law’ for the purposes of DSU art 3.2. See, for example, United States-Section 301–310 of the Trade Act 1974, WT/DS 152/R, 22 December 1999, paras 7.21–7.22; United States-Gasoline, WT/DS2/AB/R, 16; US- Shrimp/Turtle, WT/DS58/AB/R (1998) para 34.

¹⁰ That is not to suggest that this is exactly what the EU has achieved: See Mollers, T, ‘The Role of Law in European Integration’ (2000) 48 Am J Comp L 679, 683CrossRefGoogle Scholar noting it has achieved ‘islands’ of integration.

¹¹ Note that Afilalo and Foster also refer to the NAFTA regime as requiring greater integration than the WTO: Afilalo, A and S, Foster, ‘The World Trade Organisation's Anti-Discrimination Jurisprudence: Free Trade, National Sovereignty, and Environmental Health in the Balance’ (2003) 15 Geo Int'l Envtl L Rev 633, 642–647Google Scholar.

¹² A number of exceptions to this general rule have developed including the obligations imposed under the TRIPS agreement which requires Members to achieve an agreed level of intellectual property protection within their jurisdictions (TRIPS Part II) while the SPS calls for SPS measures to be harmonized ‘on as wide a basis as possible’: (see SPS, art 3). Note, however, even these exceptions do not achieve complete harmonization as they only set minimum standards.

⁴⁹ The term ‘standard of review’ in this discussion is used in its most general form to refer to its influence over the general allocation of power between the adjudicating bodies and WTO Members by dictating the extent of power to be awarded to each party on issue of law and fact: Andenas, M and S, Zleptnig, ‘Proportionality: WTO Law in Comparative Perspective’ (2007) 42 Tex Int'l L J 371, 395Google Scholar.

¹¹⁹ The AB merely stated that the necessity test formulated in section 337 as modified by Korea-Beef was correctly applied to the case by the Panel: EC-Asbestos, WT/DS135/AB/R, paras 78–79. It is interesting to note that that AB was not obliged engage with the art XX analysis as it decided against the Panel's findings that the art III:4 had been violated.

¹³³ The GATS contains three different provisions incorporating a necessity test of differing construction: See GATS arts XIV and XIV bis. ArtVI:4 imposes an indirect necessity test on Members. However, only XIV has been subject to judicial attention thus far.

¹³⁴ US-Gambling, WT/DS285/R, paras 3.211, 6.511. The only differences are: first, that GATS art XIV(a) refers to not only the GATT XX(a) exception ‘to protect public morals’ but adds ‘or to maintain public order’; and second, the provision ‘necessary to secure compliance with law or regulations’ includes a slightly different list of goals: art XIV(c). As such, it is safe to say that the differences regarding the necessity provisions are minimal.

Arts 2.3 and 5.5 are also highly relevant to the interpretation of art 5.6. Art 2.2 has not received any judicial consideration to date that focuses simply on whether the measure was ‘necessary’ but only looks at whether the measure was based on scientific evidence: Australia-Salmon, para 8.99.

¹⁴⁹ SPS Agreement, art 5.6, fn 3 (emphasis added).

Though the footnote was removed, the Note from the Secretariat affirmed that the degree of restrictiveness in the context of standard setting ‘should be proportional to the risk of non-fulfilment … in the case of the TBT’: (n 22) citing Document TER/W/16 and corr 1, (n 83) and (n 84).

²¹⁵ In rejecting the possible alternatives suggested by the EC, the AB noted that these measures ‘already figure as elements of a comprehensive strategy designed by Brazil to deal with waste tyres. Substituting one element of this comprehensive policy for another would weaken the policy by reducing the synergies between its components, as well as its total effect’: ibid para 172.
