Extract

In 1845 a master of English commercial law wrote that there was “no part of the history of English law more obscure than that connected with the maxim that the law merchant is part of the law of the land.” Since then there have been detailed studies of the medieval law merchant and of the later development of English mercantile law, but the precise status of the law merchant in England and the nature of the process by which it supposedly became fused with the common law remain as obscure as they were in 1845. The obscurity begins with the very concept of the “law merchant,” which has been differently understood by different writers and continues to be used in widely divergent senses. Some have regarded it as a distinct and independent system of legal doctrine, akin in status to Civil or Canon law, and perhaps derived from Roman law. Others have supposed it to be a particular aspect of natural law, or the universal ius gentium, and as such akin to international law.

Carter, op. cit., p. 240, says: “Possibly the law merchant was the channel through which the Roman law chiefly affected our law.” And Sir Carleton Allen said the law merchant was “profoundly affected” by Law, Roman: Law in the Making, 7th ed. (Oxford 1964), p. 274.Google Scholar Mitchell, op. cit., pp. 160–161, is guilty of equivocation on this: “Roman law was, in the main, the basis of the Law Merchant … But great as was the influence of Roman law, the customs and usages of the merchant himself remained the decisive factor … Roman law was the raw material of the Law Merchant, but that material the medieval merchant fashioned and framed as seemed good to him.” (This assumes a rather surprising degree of legal erudition on the part of the medieval merchant.)

11 Kiralfy, A. K. R., The Action on the Case (1951), p. 169Google Scholar, says of the incorporation of the law merchant: “This is a substantive field of research which has been covered by Sir William Holdsworth and others and requires no further study before 1700.” Against this somewhat dire warning, we may claim the support of two earlier American writers who dared to question conventional wisdom on the law merchant for reasons similar to those advanced here, but who did not pursue the matter in historical detail: Dr. Hoffman, cited in J. Reddie, An Historical View of the Law of Maritime Commerce (Edinburgh 1841), pp. 427–428; Ewart, J.

14 Holden seems to admit this (op. cit., p. 33, n. 5) when he adds the gloss, “surely this is what it amounts to? The courts declared the law merchant to be part of the ‘law of the land’, i.e., the common law. That it was not so, but was a separate body of doctrine with rules of its own is obvious …” (It is not obvious to the present writer.)

But the 1794 edition of Fitzherbert refers to a King's Bench precedent as late as 1616.

28 See the statutes 11 Edw. I, De mercatoribus (Stat. Regn. i, 53); Ordinance of the Staples 1353, 27 Edw. III, st. 2, c. 2 (Stat. Regn. i, 334: “soil hastive et redde proces fait devers lui, de jour en jour et de heure en heure, solonc la leie de lestaple et nemie a la comen lei”). William Noy, reading on the Statute of Acton Burnell in 1622, said, “The wise men of the law considered that the law of merchants ought to be different from the common law, for many of their contracts consist in aequo et bono without solemnity, and thereon many old judgments have been given by inspecta rei veritate … and this law was made according to the rule of the merchants, according to a form wholly different from the old law of the land”: Lincoln's Inn, MS. Misc. 29 (c) (translated from law French). This provides a contrast with the contrary statements of Davies and Coke, p. 316, below.

29 The Carrier's Case, note 21 above (translated from law French). The implication seems to be that the Star Chamber and the Chancery followed the same informal procedure. Perhaps it should read “[as] in the Chancery.” For the conciliar jurisdiction over maritime felonies, see 6 Selden Soc. xlv.

J., The Elizabethan Court of Chancery (Oxford 1969), p. 381Google Scholar, says the sixteenth-century Chancery often handled bills of exchange. There is a case in the first decree roll: Michaell v. Dyas (1545) C78/1/43 (judgment for the plaintiff where bill of exchange dishonoured).

44 The law of debt is obscure, for the procedural reason that it rarely fell open to discussion. In Grene v. Warde the facts were that A delivered £100 at Bruges to B, who was the factor of C; B directed a bill to C witnessing the payment “after the course of marchaundise,” and the action was brought against C for non-acceptance. If we analyse the situation as being that B owes A £100 and C owes B £100, and that C agrees with B to pay A £100, this was no contract because it did not discharge B's debt and so there was no quid pro quo: Pas. 1 Hen. VI, 43, pl. 30; McGovern, 13 A.J.L.H. 186. But if we analyse it differently by regarding B as C's agent for the purpose of lending, then there may have been no difficulty in regarding C as bound by the agent's contract made on his behalf: Mich. 8 Edw. IV, 11, pl. 9, per Pygot sjt (“si … jeo face un home mon factor et mon atturney pur achater marchandise etc. en cest case s'il achate marchandise d'un home jeo serra charge per tiel contract”).

45 By 1466 it was held that the steward was the judge, and therefore error lay: Mich. 6 Edw. IV, 3, pl. 9, per Choke J.; Hil. 7 Edw. IV, 23, pl. 27, per Littleton J. Recorders are rarely heard of before the fifteenth century; by 1500 most cities and boroughs had inns of court men as recorders.

46 E.g. KB 27/1037, m. 76 (error on a recovery in assumpsit in the Hereford piepowder court, 1520); Myddelton v. Foxley (1523) CP 40/1038, m. 452 (debt on a recovery in assumpsit in a piepowder court). See also 94 Selden Soc. 52, n. 2.

47 See 94 Selden Soc. 51–53. Yet the King's Bench formally decided that the rule requiring covenants to be proved by deed, and the rule requiring fourteen days between returns of writs, were not universal and did not bind local courts: 93 Selden Soc. 120, 94 Selden Soc. 258. While this paper was in proof, the writer found a case of 1491 in Caryll's reports (Line. Inn, MS. Maynard 86) where the plaintiff assigned an error in fact “que touche solement le course del ley merchant.” Hussey C.J. said, “cest un especiall ley allowable icy, quel ne pursue le comen ley … dont nous ne poimus aver conusans, per que moy semble que nous covyent descryer a ceux queux sont justices, de nous certifier lour ley; et donques poimus sacher le quel cest que il assigne pur errour soit errour ou nemy.” Kebell sjt, however, replied that the parties should join issue on any disputed point of the law merchant. The report does not resolve the doubt, but it is evident that the problem was unfamiliar. The ley, it will be noticed, is procedural.

48 From Edmund Dudley's reading on Quo Warranto in Gray's Inn (c. 1490), Cambridge Univ. Lib. MS. Hh. 3. 10, at f. 16v (translated from law French). The same passage occurs in the later readings of William Marshall (Lincoln's Inn 1516) and John Spelman (Gray's Inn 1519).

49 Stat. 17 Edw. IV, c. 2, which attempted to impose definite limits. See also the note on this statute in Spelman's Reports (93 Selden Soc.), 139, s.v. Feiers. Evidently a wider jurisdiction continued in some parts. In 1520 a plaintiff in error attempted to upset a judgment in a piepowder court, in assumpsit for a servant's wages, on the grounds that “causa actionis sive sectae non est pro aliquibus rebus seu mercandisis in mercato emptis seu venditis”: KB 27/1037, m. 76 (no judgment).

54 The bill (“cedula papiri”) read: “Be it knowen to all men that I John Barne of London oweth to Markes Colynes of Andwarp the somme of xliiij li. xiij s. iiij d. g., the whiche somme of xliiij li. xiij s. iiij d. g.

Debt would have lain if the bill had been sealed: see the earlier cases cited above, and Peirson v. Ponuteis (1608) 1 Bro. & Goulds. 102, Yelv. 135.

74 Brown v. London (1669) 1 Lev. 298, 1 Vent. 152, 1 Mod. 285, 2 Keb. 695, 713, 758, 822; approved by Holt C.J. in Stewart v. Hodges (1693) 1 Salk. 125, Comb. 204, Holt 115; and Smith v. Aiery (1705) 6 Mod. 128, 129. Where, however, A paid money to B and B gave A a bill of exchange or promissory note for repayment, it was possible to bring indebitatus assumpsit for money lent and give the bill in evidence (in which case the custom was irrelevant): 2 Keb. 758, per Hale C.J.; Bromwich v. Lloyd (1698) Lutw. 1582. The same principle could have applied where money was laid out or had and received.

75 The records do not enable us to tell exactly when this practice began, or how frequently it was followed. But the use of bills as evidence of an undertaking was approved in Eaglechilde's Case (1630) Hetley 167, Litt.Rep. 363, and we have speculated above that it may have been practised much earlier.

76 For the principle that Canon law was noticed in the royal courts, see “Ascertainment of Foreign Law: Certification to and by English Courts prior to 1861” (1979) 28 I.C.L.Q. 141, 143. The same was probably true of the lex mercatoria in the old sense. Our seventeenth-century customs are different in character.

77 The Question concerning Impositions (1656), pp. 10, 27 (written temp. Jac. I). There is a similar passage in his argument in R. v. Cusacke (1619) 2 Rolle Rep. 113. Cf. Sir Bartholomew Shower's argument in Carter v. Downich (1689) Show. 127: “It is not like a particular custom, which is confined within a certain precinct in this realm, but it is of universal extent, and concerns the whole realm; nay, reaches further, for it is jus gentium and concerns all countries where traffick is used.”

78 Co.Litt. 182.

79 Hale, M., History of the Common Law of England, ed. by Gray, C. M. (Chicago 1971), p. 18.Google Scholar Hale, however, included local custom in the same category.

80 The Interpreter (Cambridge 1607), sig. Rr3. The passage was copied verbatim in the law dictionaries of Manley, Jacob and Tomlins. Cf. Noy, note 28 above. Likewise Hussey C.J. in 1491, note 47 above.

81 Mich. 30 Edw. III, 25, per Finchden sjt; Beaulieu v. Finglam (1401) Pas. 2 Hen. IV, 18, pl. 6, per curiam; Co.Litt. 110. St. German, Doctor and Student, lib. i, Chap. VII (91 Selden Soc. 45–57) equates custom of the realm and common law.

82 Richard's Case (1542) Dyer 54, Bro.Abr., Custom, pl. 59 (alleged custom of England for merchants to assign import licences by word of mouth); Vanheath v. Turner (1621) Winch 24, per Hobart C.J., semble; Woodward v. Rowe (1666) 2 Keb. 105, 132; Carter v. Downich (1689) 3 Mod. 226, Carth. 83, Show. 127 (action of covenant).

83 Anon. (1668) Hard. 485, per Hale C.B. See also (in relation to another custom) Rich v. Kneeland (1613) Hob. 17; Matthews v. Hopkin (1665) 1 Sid. 244.

84 Sarsfield v. Witherley (1689) Show. 125, Holt 112 (liable to payee); Cramlington v. Evans (1689) 1 Show. 4, 2 Show. 509, 2 Vent. 307, Holt 108 (liable to indorsee).

85 Williams v. Williams (1693) Carth. 269, 3 Salk. 68.

86 Anon. (1668) Hard. 485. See also Hodges v. Steward (1695) 3 Salk. 68, 69 (“though the court takes notice of the law merchant as part of the law of England, yet they cannot take notice of the customs of particular places”). Cf. Peirson v. Ponuteis (1608) 1 Bro. & Goulds. 102, Yelv. 135 (“the judges ought to take notice of those things that are used amongst merchants for the maintenance of traffick”).

87 Treatise on the Admiralty Jurisdiction, quoted with permission from the edited transcript by Mr. D. E. C. Yale, to whom the writer is extremely grateful. By “special pleading” Hale presumably meant questions raised on the pleadings (including the declaration) by demurrers, writs of error and motions in banc; issue was seldom, if ever, joined on the existence of a custom, though if it had been it is difficult to see why the matter should not have been dealt with by evidence and special juries. Two of Hale's rulings at the Guildhall on questions of mercantile law are noted by C. Molloy, De Jure Maritimo (1682 ed.), pp. 280, 281.

88 This is plainly hinted at in Carter v. Downich (1689) Show. 127, Carth. 83, 3 Mod. 226.

89 Lethulier's Case (1692) 2 Salk. 443.

90 Belasyse v. Hester (1697) 1 Ld.Raym. 1281, 2 Lutw. 1589, 1593, per Powell J. (“issint que le resolucion de le court en cest case ne ledera le custome des merchants”). See also Chandler v. Meade (1705) 2 Ld.Raym. 1211, 1212.

91 Oaste v. Taylor (1612) Cro.Jac. 306, 1 Rolle Abr. 6; Mounsey v. Traves (c. 1621) Vidian's Entries, p. 66 (custom “inter mercatores apud civitatem Lond.”); Aswel v. Osborn (c. 1628) Ibid. 67 (similar).

92 E.g. Bate v. Luce (undated) Vidian's Entries, p. 70 (London and Venice); Ashurst v. Thomas (c. 1660) Ibid. 33 (London and Dublin); Clarke v. Robinson (c. 1662) Ibid. 34 (London and Amsterdam); Aboas v. Raworth (c. 1666) Ibid. 30 (London and Amsterdam); Colvile v. Cutler (c. 1666) Ibid. 31 (London and Gothenburg [Göteborg]); Walkyn v. Butts (1683) Clift's Entries, p. 897 (London and Dunkirk); Death v. Serwonters (1685), set out below (London and Venice). The custom of London was always laid in a parish and ward, but this was merely for venue purposes, since a jury could not be summoned from the city of London in general: Bromwich v. Loyd (1698) Lutw. 1582, 1585.

93 Lutw. 885, 886 (translated from Latin).

94 The point is raised by the pleadings in Claxton v. Swift (c. 1685) Lutw. 878, 3 Mod. 86, 2 Show. 441, but not argued.

95 Lutw. 892.

96 Ewers v. Benchkin (c. 1688) Lutw. 231.

97 Sarsfield v. Witherley (1689) Show. 125, Holt 112. These cases have been misread as indicating a change of heart since Oaste v. Taylor (1612), where it was objected that the defendant was not averred to have been a merchant at the time of acceptance. But in the 1612 case the custom as laid was only for merchants, whereas in the later cases it was “for merchants and others.”

98 This might even mention a bill of exchange in setting the context for the assumpsit, without relying on a custom: e.g. Vandeput v. Messam (undated) Vidian's Entries, p. 69.

99 As to the treatment of foreign law, see “Ascertainment of Foreign Law: Certification to and by English Courts prior to 1861” (1979) 28 I.C.L.Q. 141–151.

1 In fact it was a familiar complaint in the 17th century that the common law in commercial matters was too remote from the actual customs of merchants: see, e.g. Sir Josiah Child, A Discourse about Trade (1690), p. 113.
