Extract

The purpose of this article is to address two related false assumptions, or myths. The first is an assumption of public international law. It is the myth that the history of international law is one of progressive expansion, of increasing concern in public international law with matters traditionally considered private or internal to States, and that this expansion is a relatively recent phenomenon.1 The second is an assumption of private international law. It is the myth that private international law is not actually international, as it is essentially and necessarily a part of the domestic law of States.2 These assumptions, taken together, constitute the myth that public and private international law are discrete, distinct disciplines, with independent, parallel histories. This article addresses these myths through an analysis of the role played by international law theory in the history of private international law.

8 The sort of explanatory history set out in this article is in some ways an expansion or enlargement of the typical private international law history described above, through the addition of external elements. Like a more typical history, it is vulnerable to the criticism that in characterizing history as a series of ‘epochs’ it does not pay sufficient regard to the diversity and complexity of approaches adopted by different people at different times during the defined era: see M Koskenniemi ‘Book review: William Grewe: The Epochs of International Law’ (2002) 51 ICLQ 746. In its history of private international law theories and theorists, this article should not be read as a claim that these ideas were universally accepted or uniformly conceived, but only that they were (to differing degrees) influential in the development of the discipline. Thus, in its history of international norms (eg in the division between positivist, natural law and historicist approaches), this article should not be read as a claim that the norms that were adopted are coherent or conceptually independent (in fact often they are not, and perhaps ought not to be—see H Berman ‘The Historical Foundations of Law’ (2005) 54 Emory Law Journal 13), but only that they were adopted and advocated, and that they were and remain influential.

9 This article focuses on European law, because most of the world's international law (public and private) has been adopted or adapted from the European tradition. A separate tradition of private international law, which was similar to the ‘personal law’ approach discussed in II.B.1 below but probably predates the European tradition, was apparently developed in China (see JR Paul ‘Comity in International Law’ (1991) 32 Harv Int LJ 1 (henceforth Paul (1991)) 35) but later declined (see R Graveson ‘The Origins of the Conflict of Laws’ in Bernstein et al (eds), Festschrift für Konrad Zweigert (Mohr Tübingen 1981) (henceforth Graveson (1981)) 96ff, who also considers the origins of private international law both within and outside the European tradition, particularly in Africa). Contemporary practice in China reflects the European tradition: see Q Kong and H Minfei ‘The Chinese Practice of Private International Law’ (2002) 3 Melbourne Journal Intl Law 414, who suggest (at 415) that ‘Private international law was introduced in China in the early 1980s’.

11 Understanding the ideas and conditions under which private international law rules failed to evolve also helps us to understand their foundations—see Graveson (1981) 95 ff. Note, however, that C Phillipson in The International Law and Custom of Ancient Greece and Rome (Macmillan London 1911) (henceforth Phillipson (1911)) identifies ‘rudiments’ of private international law in ancient Greece (192), and ‘elements’ of private international law in ancient Rome (265).Google ScholarNote also the ancient ‘conflict of laws’ rules identified by Vinogradoff, P in ‘Historical Types of International Law’ in Collected Papers (Clarendon Press Oxford 1928) vol II 248, at 262 ff; see also Graveson (1981) 100.Google Scholar

27 The ambiguity between these two senses of ‘ius gentium’ has been important as a justificatory mechanism for legal systems deriving rules from Roman law—eg in the selective adoption of Roman law principles by English courts. See II.D below; Juenger (2001a) 20–2; Nussbaum (1954) 15 ff, 86; Maine (1861) 59–60, 107 ff, 128 (note by Pollock).

28 It has been suggested that these predated the Roman world— see, eg S Kassan ‘Extraterritorial Jurisdiction in the Ancient World’ (1935) 29 AJIL 237.

30 The idea of a ‘personal’ connection was more flexible than this might seem to imply. Juenger (2001a) 7 points out that this extended to condoning a fictional declaration of ethnicity as a sort of exercise of party autonomy. Bar (1892) 27 notes that even a private contract may be analysed (and was at this time and subsequently) as a form of temporary ‘subjection’ to the authority of a State. This form of reasoning was echoed by Grotius, and noted again by Huber—see J Weinstein ‘The Dutch Influence on the Conception of Judicial Jurisdiction in 19th Century America’ (1990) 38 Am J Comp Law 73 (henceforth Weinstein (1990)) 80–1.

31 Bar (1892) 17–21; Maine (1861) 112. Thus Westlake commented that ‘Within each of the new kingdoms, even in the same city, Roman and Lombard, Frank, Burgundian, and Goth might all be found, each living under his own personal law, very much as the Englishman, Hindoo and Mahometan now live together in India under their respective laws’: J Westlake A Treatise on Private International Law with principal reference to its practice in England (W Maxwell London 1880) (henceforth Westlake (1880)) 11; the passage appears to have been adapted from Wheaton (1845) 31; see also Yntema ‘The Comity Doctrine’ (1966) 65 Michigan Law Rev 9 (henceforth Yntema (1966)) 10; Phillipson (1911) 284.

33 Even beyond the period of the renaissance, Italian city-states resolved some practical problems through treaties which invoked and reinforced conceptions of personal law: Neff (2003) 36. For example, agreements were entered into between Italian and Islamic States, allowing Italian traders dealing with other Italians in Islamic States to use Italian law and courts to resolve their disputes. This idea was reflected in the system of capitulations— agreements (usually not reciprocal) which enabled European powers to establish their own legal community within a foreign State: Cassese (2001) 23 ff; Nussbaum (1954) 55 ff; G Simpson ‘Two Liberalisms’ (2001) 12 EJIL 537 at 544 ff. In the 19th century the system of capitulations was in some way continued through the use of judicial consuls (see Nussbaum (1954) 208), the applicability of laws in the Turkish empire was (still) largely based around the personal laws of the parties, and in many countries disputes involving Jewish persons (eg the validity of a Jewish marriage) were tried according to Jewish law, at the time a purely personal, tribal law without a territorial situs: see Savigny (1880) 58–9, 60–2 (Guthrie note); Bar (1892) 20–1; J Westlake A Treatise on Private International Law or The Conflict of Laws with principal reference to its practice in the English and other cognate systems of jurisprudence (W Maxwell London 1858) (henceforth Westlake (1858)) 134–47. The continuation of this practice in the colonial subcontinent is also noted by Westlake (see n 31 above), although of course, particularly in the colonial context, the extent to which these recognitions of personal law are signs of the acceptance of a theory of world order (and not merely an exercise of power) is debatable, given the lack of reciprocity in the arrangements. In any case, the influence of the personal law approach is still felt today, for example, in the diverse religious laws recognized in India and in some Islamic States.

34 Often this is described as a result of the movement of scholars west because of the decline and eventual fall in 1453 of the Byzantine empire, although much influence predates this period— communication is more likely to be the cause than migration. See Nicholas (1975) 45 ff; Nussbaum (1954) 54–5; Kelly (1992) 82 ff, 165 ff—who also suggests (at 86, 120), however, that it was not the Byzantines but the Islamic expansion to the west which transmitted much of this knowledge.

35 Neff (2003) 34. Note that ‘scientific’ really carries two meanings. The sense being analysed here is the idea of deductive reasoning from first principles, rather than the inductive experimental science which founds positivist theory, which is discussed in III.A below.

36 Neff, (2003) 34; Kelly (1992) 142. The form of ‘natural law’ which derives from the presumption of an objective sense of reason is probably most closely related to the Roman conception—see Kelly (1992) 57 ff.Google Scholar

39 Aquinas, ‘Summa Theologica’, Ia 2ae 93 3, cited in Kelly (1992) 136. The idea of ‘right reason’ was again inherited from the Stoic school—see Rommen (1936) 23.

41 Note the parallel between the ‘deductive’ method and the idea of a ‘descending’ pattern of justification in M Koskenniemi From Apology to Utopia: The Structure of International Legal Argument (Lakimieslüton Kustannus Helsinki 1989) 41.

42 It is sometimes argued that this phenomenon was a result of the same Islamic threat which provided the Italian renaissance with scholars from the Byzantine empire—see above n 34; Juenger (2001a) 9. Kelly (1992) 117ff suggests that the city organization survived from the Roman empire.

43 eg uniform commercial laws facilitated trade, culminating in the development of a lex mercatoria which was ultimately widely accepted across Europe: see II.D below; Nussbaum (1954) 27 ff;Google ScholarBaker, JH ‘The Law Merchant and the Common Law before 1700’ (1979) 38 Cambridge LJ295 (henceforth Baker (1979));Google ScholarJuenger, F ‘The lex mercatoria and Private International Law’ (2000) 5 Uniform LR 171.CrossRefGoogle Scholar

50 The first attempt at private international law rules is usually attributed to Aldricus, in Bologna in the late 12th century, who argued that the court, when faced with a dispute connected with more than one legal system, should apply the ‘better and more useful’ law: see Wolff (1950) 22; Yntema (1966) 12; on Bologna in this period see further Kelly (1992) 120 ff. The concept that there is a ‘better’ law demonstrates the natural law foundations of this approach; the comparative nature of the test suggests a competitive improvement and development of the law towards a universal ideal, not the existence of diverse laws: Yntema (1953) 302.

51 Kennedy argues that the distinction between international law and municipal law was itself largely unknown to ‘primitive’ international law scholarship:

Kennedy, David ‘Primitive Legal Scholarship’ (1986) 27 Harv Intl LJ 1 (henceforth Kennedy (1986)).Google Scholar

52 Phillipson (1911) suggests that these two types of law can also be identified in ancient Greek (at 200) and Roman (at 284–5, 295–6) law, and thus that the statutists were merely drawing on and expanding ancient approaches.

53 This may be seen, for example, in the development of feudalism, which was a combination of personal and territorial rights and duties—typically the grant of land use rights in exchange for goods or personal services (eg, farming) or an oath of personal loyalty (usually for purposes of military service): see Yntema (1953) 302–3; Bar (1892) 22; Kelly (1992) 97; Paul (1991) 12 ff; Lipstein (1972) 109 ff; Nussbaum (1954) 22–3.

54 The statutist approach is most closely associated with the natural law theorist, Bartolus: see Wolff (1950) 23–5; Nicholas, (1975) 47;Google ScholarYntema, (1966) 13 ff. The fame of Bartolus, and incidentally the continued dependence on Roman law (even private international law principles were, dubiously, ‘derived’ from Roman law), was expressed in the slogan ‘Nemo romanista nisi bartolista’ (‘If you're not a follower of Bartolus, you're not a scholar of Roman law’)—Kelly (1992) 122. Bartolus is, however, only the most prominent figure of a varied and complex tradition: see Juenger (2001a) 10;Google Scholarde Nova, R ‘Historical and Comparative Introduction to Conflict of Laws’ (1966) 118–III Recueil des Cours 435 (henceforth de Nova (1966)) at 441 ff;Google ScholarYntema, (1953) 304;Google ScholarWolff, (1950) 29;Google ScholarWestlake, (1858) p 130;Google ScholarWestlake, (1880) 9;Google ScholarLipstein, (1972) 110 ff;Google ScholarNussbaum, (1954) 41;Google ScholarLorenzen, ESelected Articles on the Conflict of Laws (Yale University Press New Haven Conn 1947) (henceforth Lorenzen (1947)) 182 ff. Juenger suggests that the tradition included more recognizably ‘modern’ rules, including both multilateral choice of law rules and choice of law rules selecting laws based on the location of events (not statutory interpretation).Google Scholar

57 Wolff, (1950) 25;Google ScholarYntema, (1966) 15;Google ScholarNussbaum, (1954) 42. Note the characterization of this as a typical phase in the decline of a legal distinction in Duncan Kennedy ‘The Stages of Decline of the Public/Private Distinction’ (1982) 130 U Pa L Rev 1349 at 1351.Google Scholar

58 Bar (1892) argues at 33 that the statutist method fails because there is ‘no real substantial ground of classification to take up’. Bartolus himself (see n 54 above) infamously struggled to categorize the English rule of primogeniture, according to which all property was inherited by the first born son (see Gutzwiller (1977) 294), and was criticized for his attention to the form of wording used in the expression of the rule: see Juenger (2001a) 11; Wolff (1950) 25; Bar (1892) 28; d'Oliveira (2002) 114. A later statutist, De Coquille (see Juenger (2001a) 15–16), argued for a more teleological interpretive methodology, based on the presumed intention of the legislator, perhaps anticipating contemporary American policy analysis approaches: see B Currie Selected Essays on the Conflict of Laws (Duke University Press Durham NC 1963); Cheshire and North (1999) 25 ff. We should note that Bartolus's resolution of this problem was also partly supported by the argument that the English law was ‘odious’ (and not ‘favourable’). This may be seen as an echo of the ‘better law’ approach developed originally by Aldricus, see n 50 above, and more recently advocated in the United States, or even a very early expression of the idea that laws might be excluded because of ‘public policy’: Juenger (2001a) 12; see V.B below. The focus on statutory policy by De Coquille is probably broadly a contributor to this trend as well. Bar (1892) 31 points out that what is favourable for one party is clearly odious for the other, which perhaps suggests that ‘odious’ and ‘favourable’ were intended to carry an objective, natural law meaning; see also Yntema (1966) 14; Lipstein (1972) 119.

60 Far from being a coincidence, this is a key theme in the history of private international law— see, eg Yntema (1953) 299; Wolff (1950) 20; Juenger (2001a) 13.

62 Westlake (1858) 123 suggests that this argument relied on the separation of human (customary) law from Roman law, with only the former subject to the intention of the parties. Du Moulin did not just recognize actual party intentions, for example, expressed through an agreement, but appeared to admit fictional tacit agreements (what we would call an imputed agreement). This is, of course, actually an objective test, focusing on the factual circumstances, and not a subjective analysis of the intentions of the parties at all. A focus on the facts and away from the interpretation of law is encouraged more generally by the emphasis on party intentions, and in this innovation Du Moulin's approach very much laid the foundations for a modern proper law approach: see Juenger (2001a) 14; Yntema (1953) 304–5; IV.B below.

63 Although it continued to be influential, even until the early 19th century: see S Livermore, Dissertations on the Questions Which Arise from the Contrarity of the Positive Laws of Different States and Nations (B Levy New Orleans 1828); Juenger (2001a) 26; Baker (1993) 466 ff; Paul (1991) 20–1.

64 Bar, (1892) 29;Google ScholarShaw, (2003) 21. ‘Territorial sovereignty’ received its first systematic analysis by Bodin in late 16th-century France: see Yntema (1953) 305;Google ScholarYntema, (1966) 18;Google ScholarKelly, (1992) 158 ff, 175. Nussbaum (1954) 77 points out that Bodin's theory of absolute sovereignty may be contrasted with the reality of fractured power within the French kingdom, suggesting his theory had a political agenda of centralization in support of the monarchy.Google Scholar

65 Neff, (2003) 38. The personal element of feudal relations (see n 53 above) was reduced as they evolved into merely a system of land title: see Yntema (1953) 305;Google ScholarWestlake, (1880) 12.Google Scholar

69 In reflecting this drift, D'Argentré is himself also manifesting the trend away from universal, natural law solutions towards a ‘positivist’ dependence on the behaviour of States—see III.A below.

70 An English jury traditionally consisted of men from near the location of the disputed act or thing, who would therefore be expected to serve both as adjudicators and as witnesses (of the event or the character of the disputants): see for example Baker (1993) 463; Cheshire and North (1999) 16 ff. The English court had no power to order foreigners to serve in juries, which initially rendered the courts powerless to deal with disputes concerning foreign property or events.

71 See Maine (1861) ch 2. For example, in a case involving property in Brussels, a claimant might plead (and the defendant would accept) that Brussels was in London, in order that a jury could be empanelled: see Juenger (2001a) 19; Baker (1979) 303. A typical example is Mostyn v Fabrigas (1774) 98 Eng Rep 1021. This might also be viewed as a method of accommodation of party autonomy. The need for this approach declined with changes to the role of juries and the rules regarding their formation: see, eg Cheshire and North (1999) 17.

However it is useful to note the contrast with Grotius's early work, ‘De Jure Praedae’, or ‘Of the Law of Prizes’, written about 1604 and unpublished during his lifetime (published 1950, trans by G Williams ). This early work adopted a more systematic, natural law approach to the analysis of international law, in which (see, eg, 26) the positive law of nations was clearly secondary to natural law.

139 See VI.A below.

Thus, the main international law issues of the 19th century were not diplomatic but (very familiar) economic issues—the pushes towards global freedom of trade through tariff reductions, the ‘rationalization’ of the movement of peoples and the globalization of the international economy (through the gold standard), all in support of the penetration of European capital into the developing world: Neff (2003) 45; Nussbaum (1954) 203 ff, 210 ff.

In its reliance on discretionary ‘comity’ as the solution to ‘conflicts of law’, in an attempt to reconcile sovereignty with the application of foreign law by a court, the Dutch school incidentally implied a positivist methodology for the study of private international law. If foreign law is applied purely as a matter of discretion, the only possible way to study it and formulate more detailed ‘rules’ is to examine the practice of States, and generate rules by induction: see Bar (1892) 43; cf III.A n 102 above.

165 See Wardaugh (1989). Story was influenced by Pufendorf, and by the natural law philos-opher William Paley, who was himself heavily influenced by Pufendorf—see III.C above.

166 Janis (2004) asks (at 23–4), ‘Could it be that one reason why no [treatise on conflict of laws] existed [before Story] was that heretofore, in Blackstone's fashion, the law of nations had been comprehended in such a way as to encompass some or all of the problems Story addressed under the rubric ‘conflict of laws'?’ See III.C above,

This approach was particularly influential in the United States and in the United Kingdom, perhaps partly because it sits well with the pragmatic, more utilitarian conceptions of law in these States: Bar (1892) 45–6. Ironically, it may be that Story's successful application of this method actually reduced its future application, and particularly the practice of referring to foreign sources, as later authors merely cited Story's own work rather than engage in a comparative analysis.

175 It is not entirely clear whether Story was committed to the idea of ‘vested rights’, at least in the sense later adopted by Dicey (see III.D.4 below), although it is arguably implicit in Huber's third rule (see III.D.1 above); Baker (1993) 503 ff. Story's approach to conflicts did emphasize his ‘conviction that individuals rather than nations or States are the primary repositories of rights’: Baker (1993) 472. Baker also argues that ‘Story cast his private international law rules as guardians of contractual entitlements and proprietary interests’ (476), and that his private international law work ‘is best characterized as a heuristic, constitutional essay on the correlative scope of private and public sovereignty’ (488).

176 Story (1834) 35; Born (1996) 549. Note the argument in Baker (1993) 459 that ‘Manipulating the concept of comity by emphasizing the fiction of willing ratification … helped Story reconcile popular sovereignty with principles of international law derived from an older, natural-law tradition’; cf IV.A below.

183 Note the change in title from Westlake (1858) (‘A Treatise on Private International Law or The Conflict of Laws with principal reference to its practice in the English and other cognate systems of jurisprudence’) to Westlake (1880) (‘A Treatise on Private International Law with principal reference to its practice in England’). With the development of English private international law between these and subsequent editions, Westlake increasingly focused on English cases to the exclusion of foreign judgments and jurists.

184 Westlake (1858) iv; note also that this anticipates Kahn's arguments in VI.A below. An additional argument, also discussed in VI.A below, points to the increasing ‘completeness’ of the English legal system, removing the need for references to foreign legal jurisprudence in the development of the English law.

187 Westlake (1858) 128. Note however that Westlake does not appear to apply this characterization to the international sphere in his later writings on international law, arguing that international law only required a ‘society of States’—Westlake, ‘Chapters on the Principles of International Law’ (1894); see Koskenniemi (2002) 48 ff.

188 Westlake (1858) 131. It should be pointed out that this argument seems to beg the question, unless by power Westlake means material power and not legal authority, in which case it becomes a legitimisation of force. Note that it echoes John Voet, and also Cocceji's argument in the 17th century—see Gutzwiller (1977) 301.

223 This is unsurprising given the pre-eminence he gave to Roman law. It is interesting to note that Savigny was writing in the context of the customs union which preceded German unification: another context of diversity within a unified system—see II.C, III.D.1 above; Nussbaum (1954) 192 ff.

Savigny lectured at the University of Berlin in the enormous shadow of Hegel's influence, and in fact taught historical jurisprudence to a young Karl Marx, whose writings continued to bear a Hegelian hallmark despite his later rejection of Hegel's idealism. See V.A below.

226 Savigny (1880) 68; Wolff (1950) 35–6.

227 Bar (1892) 55 describes Savigny's approach in a way which emphasizes its natural law origins; see also Lipstein (1972) 133 ff; A Nussbaum ‘Rise and Decline of the Law-of-Nations Doctrine in the Conflict of Laws’ (1942) 42 Columbia LR 189 (henceforth, Nussbaum (1942)), 191 ff—but note (at 196) Nussbaum's argument that Savigny was not visualising the sort of international community posited by Wolff.

228 Savigny (1880) 71; de Nova (1966) 459 ff.

229 Perhaps positing an international system of regulation as a counter to the growth of global liberalism—see VI.A below. See also discussion in M Reimann ‘Savigny's Triumph? Choice of Law in Contracts Cases at the Close of the Twentieth Century’ (1999) 39 Virginia J of Intl Law 571 (henceforth, Reimann (1999)) 599 ff.

230 Savigny (1880) 140–2. Although at 48 he does appear to suggest that the statutist methodology (fixing the limits of each law) would give the same results as his approach (fixing the law of each legal relation) in any event.

231 See III.D.4 above.

232 Savigny (1880) 147; see also Castel (1994) 29; Collier (2001) 381. The popularity of the idea of vested rights seems inconsistent with the obvious logical flaw that Savigny points out— that for rights to ‘vest’ you must have already determined which legal system applies, hence the idea is circular. Perhaps the reason for its popularity is that whether or not it is circular depends on your concept of law. If you adopt a legal positivist position, and ‘rights’ exist only when enforced by a legal system, the idea of ‘vested rights’ is circular, if not nonsensical. If, however, you adopt a natural law position, rights exist at the time an act or event occurs—according to natural law, not the law of any actual legal system—and there is an obligation on a legal system to recognize them. Such rights may rest on a (natural or international law) claim about the supreme territorial sovereignty of each State—such as that made by Huber. The attachment of Huber and even Dicey to this position shows a closer affinity to natural law theory than is usually recognized.

238 Savigny (1880) 144–7.

239 Although arguably the dominance of liberal theory (and its natural law foundations—see IV.A above) means that this would not have appeared to Savigny to undermine the universal or natural law character of his approach.

240 Westlake (1858) 158 interestingly explains the fact that procedure is governed by forum law by characterizing procedural rules as commands issued to the judge, not the individual.

241 Savigny (1880) 76 ff; see also Guthrie's note on the uncertainty of defining ‘public policy’ in practice at 81–4. Bar (1892) 65 accepts that ‘owing to the far-reaching differences in the moral conceptions of different nations and States, there must be gaps in the international community of law’, but advocates a narrow public policy exception for the reason of its potential uncertainty— only immoral legal relations to be realised in the forum territory can be disapplied under forum public policy; see further Savigny (1880) 84 (Guthrie note).

242 Savigny (1880) 80; de Nova (1966) 469 ff. This is of course the opposite of what actually happened in the 19th century—see V.B below. This ‘progressive’ view of history again shows the influence of Hegel on Savigny: see V.A below; Savigny (1880) 57—‘the positive law itself has its seat in the people as a great natural whole’; ‘it is only in the State that the will of individuals is developed into a common will, it is there only that the nation has a realized existence’.

246 To apply only local law would, according to Bar, not merely lead to loss of trade, but ‘would lead in many cases to a simple denial of the rights of the foreigner, and even of the native citizen himself, or in other words, would deprive international intercourse of all legality’—Bar (1892) 2. Note that Bar here appears to draw upon both the language of vested rights theory (see III.D.2 above), rejected by Savigny, and a sort of natural law theory, in his claim that a direction to apply local law would lack ‘legality’. Note also the apparent influence of Mancini—see n 274 below.

Juenger, FK ‘Private International Law or International Private Law?’ (1994) 5 King's College LJ 45 (henceforth Juenger (1994)); Nussbaum (1942) 196 ff. Savigny's influence in the United States may also be attributed to Field, who, accepting the idea of private international law as part of a broader international law system, argued for a greater influence of territorialism in Savigny's method. Field's influence is perhaps most apparent in his brother's role as a Supreme Court judge, for example in Pennoyer v Neff (1877) 95 US 714. See further F Juenger ‘David Dudley Field's Contribution to the Conflict of Laws’ in Selected Essays on the Conflict of Laws (Transnational Publishers Ardsley NY 2001) (henceforth Juenger (2001b)); Weinstein (1990) 76 ff.Google Scholar

250 This term has been used in a number of different senses: see Allott (2002) 332; Hershey (1912) 34; Neff (2003) 41 ff. Neff's approach is adopted here.

251 Neff (2003) 41 ff; Shaw (2003) 28–9. A central issue of the historicist approach, which emerges from this dualism, is that it is sometimes ambiguous about whether it is a descriptive or normative project, whether it claims that ‘progress’ is inevitable or desirable. One famous instance of this ambiguity is the problem of revolution in Marxism, which is both the inevitable result of material historical forces, and a ‘call to arms’.

253 Particularly Wolff and Kant: see IV.A above; Hochstrasser (2000) 174 ff. Note however that Kant's conception of humanity as social was a claim about rationality not historical inevitability.

The debt owed by Marx to Hegel is obvious here. Marx, however, adopted a more critical perspective towards the unity of the national will, highlighting the role of competing classes—see Rommen (1936) 125. In this Marx also owed a debt to the Sophists of ancient Greece—see Rommen (1936) 9.Google Scholar

266 Hegel viewed war as a natural part of the resolution of the conflict of State wills—see Hegel (1821) 369. The widespread influence of the idea of a moral hierarchy may broadly be recognized in both Marxism and, in combination with late twentieth century Social Darwinism, fascism, which shared a belief in the moral superiority of one form of the State, as arguably does contemporary American liberalism. Rommen argues, alternatively, that totalitarianism is the inevitable consequence of the adoption of positivism—see Rommen (1936) 152. For the influence of Hegel on Marx (through Savigny) see n 225 above. Nussbaum (1954) 238 discusses the openly hierarchical approach developed by Lorimer under this influence.

It is important here to distinguish an approach based on ‘nationality’ from one based on ‘nationalism’—Mancini's approach was far from being motivated by the interests of a single nation. In fact (like Savigny) he argued for an international order, which (unlike Savigny) adopted nationality as the founding concept and the key determinant in attributing legal disputes to States. The absence of nationalism is demonstrated, for example, by the development of the exequatur as a streamlined method for the recognition of foreign judgments in the Italian Civil Code of 1865— see n 280 below.

290 Evidence of the problems caused by a diversity of legal categories may be seen in the ‘problem’, ‘theory’ or ‘device’ of characterization, under which ambiguities in private international law ‘categories’ are arguably susceptible to being exploited, with judges interpreting cases as belonging to the category which gives the most favourable result: see Dicey and Morris (2000) ch 2; Lorenzen (1947) 115 ff; Lipstein (1972) 198 ff. Of course this may result not merely from diversity in legal categories, but from ambiguity or flexibility in the categories themselves, within a legal system: see for example L Collins ‘Interaction Between Contract and Tort in the Conflict of Laws’ (1967) 16 ICLQ 103.

301 Note the famous judgment by Story (consistent with his own role in the development of private international law—see III.D.2 above) distinguishing public and private corporations in Trustees of Dartmouth College v Woodward (1819) 17 US 518 at 669–73; see Horwitz (1982) 1425. The connection is most obvious in the priority given to party autonomy in private international law:

see for example Yntema, H ‘Contract and Conflict of Laws: ‘Autonomy’ in Choice of Law in the United States’ (1955) 1 New York Law Forum 46.Google Scholar
