87. Thus, Dolinger argued that a distinction should be made between those public policy principles which are common to all national legal systems and those principles which constitute the world public policy, the former not necessarily pertaining to the real ordre public of the international community. This latter is not a ‘common public policy”, but the public policy which establishes ‘universal principles, in various fields of international law and relations, to serve the higher interests of the world community, the common interests of mankind, above and sometimes even contrary to the interests of individual nations’. See Dolinger, loc. cit. n. 82, pp. 171–172.

88. See the judgments and arbitral awards referred to by Lalive, loc. cit. n. 82, pp. 274–308.

89. An often cited example of the operation of transnational public policy and its relevance in the area of international arbitration is ICC Case No. 1110/1963, Doc. No. 410/1056, partly published in Lew, op. cit. n. 2, pp. 554–555. The importance of the doctrine for international commercial arbitration has been acknowledged in the UNIDROIT Resolution on Arbitration and Foreign Enterprises, adopted in 1989 at the Institute's session at Santiago de Compostela. The pertinent provisions read as follows:

‘Article 1.

Arbitrators derive their authority and legitimacy from the parties’ agreement providing for arbitration. The arbitrator should neither exceed his authority nor do less than is required to exercise that authority completely. He should respect, however, the peremptory norms of truly international public policy.

Article 2.

A truly international public policy exists when the emergent international order served by arbitration has reached a consensus on a given economic, political, or social issue.

Article 5.

…Subject only to the requirements of international public policy as defined in Article 2, the parties have full autonomy to shape the procedural and substantive rules and principles that will govern the arbitration.’

See 63 Ann IDI (1989) pp. 203–204.

90. According to Lew, the effect of transnational public policy, when applied by international and non-national courts or arbitral tribunals, is not to‘ replace or displace the law deemed applicable’, but ‘rather…to directly influence the arbitrators’ award within the confines of the “public policy appropriate to international relations”’, Lew, op. cit. n. 2, p. 539.

91. Thus, M. Forde, commenting on the decision of the Cour d'appel de Paris in Club Mediterranée v. Caisse des Ongés Spectacles observed that ‘the term laws d 'application immédiate used by the Cour is merely a special name for ordre public functioning in this assertive sense’, see Forde, M., ‘The “Ordre Public” Exception and Adjudicative Jurisdiction Conventions’, 29 ICLQ (1980) p. 260.Google Scholar An assimilation of ‘rules of public order in a positive sense’ with lois d'application immédiate has also been made by Kokkini-Iatridou, loc. cit. n. 50, p. 288; and Lalive, loc. cit. n. 82, pp. 263–264. See also M. Rubino-Sammartano who, supporting the distinction between the positive and negative functions of ordre public, considers public policy as including both normes d'application nécessaire and the principles of public policy, in InternationalArbitration Law(1990) p. 299.

See, e.g., Sauveplanne, J.G., ‘New Trends in the Doctrine of Private International Law and Their Impact on Court Practice’, 175 Hague Recueil (1982–II) pp. 35–36,Google Scholar who stated: ‘now we have discovered a concept [of lois a'application immédiate]that seems better to explain the phenomenon than the controversial one previously used [the concept of positive ordre public] would it not be preferable to strike out the latter from our vocabulary, instead of creating new confusion by trying to elaborate new distinctions?’ See also Vitta, E., ‘Cours général de droit international privé’, 162 Hague Recueil (1979–I) pp. 121–122.Google Scholar According to Vischer, although ‘the ordre public as an instrument to safeguard substantive values and even interests of the lex fori is certainly at the source of the doctrine of “lois d'application immédiate”… the ordre public clause has undergone a significant change’, its effect being nowadays primarily negative.

A Collection of Essays (1990) p. 60;Google Scholar Mosconi, loc. cit. n. 4, p. 124. This conclusion may also be inferred from the fact that the provisions of the 1980 Rome Convention on the public policy mechanism and lois d'application immédiate are to be found in two different articles, Art. 16 and Art. 7, respectively. But see Sperduti, G., ‘Normediapplicazionenecessariaeordinepublico’, Riv. Dir. Int. Priv. Proc. (1976) no. 3, p. 490,Google Scholar who stated ‘c'è, in particolare, un autentico bisogno di mantenere aucorate le norme di applicazione necessaria alia nozione di “ordine publico”, poiché é proprio con richiamo a tale nozione che si spiega la particolare efficacia conferita alle norme stesse’.

The stated general rule does not apply as far as the applicability of foreign mandatory rules is concerned. Another exception from this rule has been noted by Grigera Naón, who referred to Art. 14(4) of the Argentine Civil Code, providing that priority be given to the application of Argentine law if more favourable to the validity of an international contract than the conflicting foreign law. This provision presupposes the overriding application of the Argentine law only after prior determination of the law applicable to the contract. See Grigera Naón, loc. cit. n. 50, p. 13.

102. See, e.g.,Guedj, loc. cit. n.4, p.667, fn. 27: ‘The ordre public exception expresses some hostility to the application of foreign law. The application by the forum of its loi de police only expresses indifference as to foreign law. To that extent, the forum is in a more neutral position than when its ordre public is invoked’.

103. According to Vischer, the notions of public policy and mandatory rules express the different concern of the forum State. The ‘ordre public’ mechanism ensures the protection of basic moral values and principles of justice while lois d ‘application immédiate are rules that ‘guarantee the functioning of the State's administration and of State related activities’, such as the State's supervision of certain private activities in the field of insurance and banking, the safeguarding of the economic order and social welfare, etc. See Vischer, loc. cit. n. 98, p. 102.

112. The Draft Rules have been elaborated by the Working Group of the Commission on Law and International Commercial Practices of the ICC for the purpose of providing greater uniformity in the techniques available to arbitrators for the determination of the law applicable to contracts. The relevant article of the Draft Rules reads as follows: ‘Even when the law of a certain country is not the legal system applicable to the contract, the arbitrator may nevertheless give effect to mandatory rules of the law of that country if the contract or the parties have a close contact to that country, and if and insofar as under its law those rules must be applied to the issue whatever be the legal system applicable to the contract. On considering whether to give effect to these mandatory rules regard shall, inter alia, be had to:—whether in view of the nature and purpose of the rules the interests of international trade will be promoted or impaired by their application to the issue and,—whether their application or non-application to the issue would further the enforcement of the award’, Draft Rules on the Law Applicable to International Contracts, Commission on International Arbitration, ICC Doc. No. 420/241, 1981, pp. 4–5. It is noteworthy that whilst generally following the pattern of Art. 7(1) of the 1980 Rome Convention, the present provision limits the broad ‘nature’ and ‘purpose’ criteria to those aspects relevant to promoting the interests of international trade, and the consequences of mandatory rule (non-)application have also been limited by considerations of strengthening the enforceability of the award. The work on the ICC Draft Rules was later discontinued due to some fears that codification of the choice-of-law methods in arbitration would result in restraining the freedom of arbitrators.

113. The Guide was adopted by UNCITRAL at its 20th session in August 1987 as a recommendation to assist parties in drawing up international contracts for the construction of industrial works. Concerning mandatory rules, the Guide contains the following provision, which even offers some guidance as to their identification: in addition to legal rules applicable by virtue of a choice of law by the parties, or by virtue of the rules of private international law, certain rules of an administrative or other public nature in force in the countries of the parties and in other countries (e.g., the country of a subcontractor) may affect certain aspects of the construction. These rules, which are often mandatory, are usually addressed to all persons resident in or who are citizens of the State which issued the rules, and sometimes to foreigners transacting certain business activities in the territory of the State. They may be enforced primarily by administrative officials. Their purpose is to ensure compliance with the economic, social, financial or foreign policy of the State. The parties should therefore take them into account in drafting the contract… Certain of these legal rules concern technical aspects of the works to be constructed… Other legal rules prohibit or restrict exports, imports, the transfer of technology and the payment of foreign exchange. As a result of the operation of those rules, a contract may be invalid, terminated, or legally impossible to perform’. See Legal Guide on Drawing Up International Contracts for the Construction of Industrial Works, UN Doc. A/CN.9/SER.B/2.

114. While generally acknowledging the principle of party autonomy, this Resolution makes a reservation as to ‘the question of a possible operation of public policy or mandatory legislation in this field’, see 58 Ann. IDI (1979) part 2, p. 193.

According to the Belgian Law of 27 March 1985, any application for judicial review of arbitral awards rendered in Belgium is expressly excluded if no party has any connection with Belgium, see 11 YB Com. Arb. (1986) p. 369. Under Art. 192 of the Swiss Private International Law Act, the action for setting aside may be totally or partially excluded by the parties to an arbitration agreement where both parties do not have their domicile, habitual residence or business establishment in Switzerland, see 13 YB Com. Arb. (1988) p. 451. The 1979 UK Arbitration Act allows parties to international cases to exclude the right of appeal to the High Court on questions of law, provided that the parties’ contract does not belong to a ‘special category’, such as insurance and commodity contracts. According to English judicial practice, reference by the parties in their agreement to ICC Arbitration Rules, providing in Art. 24 for the finality of awards, constitutes a valid exclusion agreement. See 5 YB Com. Arb. (1980) p. 231 and Berger, loc. cit. n. 83, p. 631. Most other developed arbitration laws contain the non-excludable, but exhaustive lists of grounds for annulment, see An. 1068 of the Netherlands Arbitration Act, in 12 YB Com. Arb.

In the opinion of Grigera Naón, the basic principle of transnational public policy is the requirement that international arbitration should not be used as a mechanism by which to allow the parties ‘to achieve fraude à la loi étrangère’, see Grigera Naón, loc. cit. n. 3, pp. 72–73.
