Abstract

This article considers prescription as a customary standard of legal validity which enables judges to identify certain customs as law even though the status of those customs as law cannot be ascribed to a law-making authority. Although claims as to customs having prescribed are often bound up with claims as to the quality (as opposed to the validity) of custom as law, prescribed custom is properly conceived to be a feature of the rule of recognition – a criterion by which a court can identify, and declare, a custom as already existing law as distinct from both custom without the force of law and custom turned into positive law.

16 “Austin … held that … customary practices were not law until the courts … recognized them … . Hart reversed Austin on this point. The master rule [sc., the ultimate rule of recognition], he says, might stipulate that some custom counts as law even before the courts recognize it. But he does not face the difficulty this raises for his general theory because he does not attempt to set out the criteria a master rule might use for this purpose”.

I use “community custom” to refer to national and local customs as distinct from customs of the legal profession. Local (particular) and national (general) custom, we will see in the next section, are distinct concepts in English law.

19 See Raz, J., “Legal Principles and the Limits of Law” (1972) 81 Yale L.J. 823CrossRefGoogle Scholar, at 852–53; also Lamond, G., “Legal Sources, the Rule of Recognition, and Customary Law” (2014) 59 Am. J. Juris. 25CrossRefGoogle Scholar. Lamond's account is particularly interesting because he sees the difficulties in squaring this line of argument with what is meant to be a positivist legal theory: if customs in foro are accommodated by the rule of recognition, he observes, we have a legal system in which the rule of recognition extends to standards which courts customarily treat as binding but which are not validated by statute, precedent, a constitutional provision or any other posited source of law (ibid., at pp. 34–35). Nevertheless, he appreciates that some squaring has to be done, because judges within municipal legal systems do enforce community customs which conform to “non-source-based” standards of legal validity (p. 35). Rather than invoking the rule of recognition to explain how they do so, he argues that judges understand the non-source-based standard as “authoritatively binding” – to be followed not because of “the merits of the standard itself” but because “it is part of the law” and so is something which they “are duty-bound to apply” (p. 45). To say that judges identify community customs as having legal validity by virtue of their conformity to a standard which is “part of the law” seems to entail acceptance of the rule of recognition (modified to allow custom in foro to feature in its content). The point for emphasis is that Lamond, like Raz, accepts that judges try to identify community custom as law (rather than turn community custom into law) when they declare its conformity to a standard of legal validity which is accepted as customary law of the courts.

20 Under the Prescription Act 1832, s. 2, evidence of 20 years’ continuous and uninterrupted enjoyment of an easement establishes a strong presumption that, at some time earlier, there was a (now lost) grant of the easement to the dominant neighbouring estate and that the holder of that estate enjoys the easement as a prescriptively acquired right. The presumption is practically unassailable because it can only be rebutted by proof that the grant could not have been made in the time before the prescription period but after the year 1189 (about which more later). In any event, once user has run for 40 years, the prescriptively acquired right becomes absolute.

21 Prescription stands as a vivid illustration of how lawyers can accept a standard of legal validity as part of the rule of recognition while disagreeing – not empirically but theoretically – over what is required for that standard to be satisfied. On empirical disagreement (over whether a rule satisfies a criterion of legal validity) as distinct from theoretical disagreement (over what the criterion of legal validity actually is), see Dworkin, R., Law's Empire (London 1986), 46 Google Scholar. Hart never denied the possibility of theoretical disagreement over criteria embodied in the rule of recognition: see Hart, The Concept of Law, pp. 245–47.

36 Mercantile custom, for example, was more often local custom rather than, as Finch insisted, common law: see J. Baker, “The Law Merchant and the Common Law Before 1700” (1979) in his Collected Essays on English Legal History: Volume III (Cambridge 2013), 1238–44Google Scholar.

37 The common law did not have to be proved but the presumption that a custom was common law could be rebutted. In Section III, this point is raised in relation to customs presumed immemorial. Here, it is worth noting that a custom considered common law could lose this status if it became evident that the custom did not prevail in every locality, even though it prevailed in nearly every locality, throughout the realm. For one such custom (concerning recovery of a decedent's personal property), see Palmer, R.C., English Law in the Age of the Black Death, 1348–1381 (Chapel Hill, NC 1993), 9293 Google Scholar.

38 See e.g. Reniger v Fogossa (1550) 1 Plowd. 1, 9, per Atkins, apprentice counsel.

For examples in Bracton, see Ibbetson, “Custom in Medieval Law”, pp. 163–64. The author of Britton (c. 1290) alludes to the distinction when remarking on customs used in the county other than the common law”. Britton, 2 vols, ed. and trans Nichols, F.M.

39 An obvious difficulty with depicting the common law as immemorial general custom is that the customary features of later common-law systems cannot be fitted into the account: for an elaboration of the point with regard to the reception of English common law in America, see Bridwell, R. and Whitten, R.U., The Constitution and the Common Law (Lexington, MA 1977), 1518 Google Scholar; also Bederman, D.J., Custom as a Source of Law (Cambridge 2010), 105CrossRefGoogle Scholar.

46 There is no reason to think that Coke was not being deadly serious when he claimed that the common law dated from 2860 BC, when Brutus came from Troy (E. Coke, “To the Reader” (1602) in Third Part of the Reports of Sir Edward Coke, Kt (London 1738), viii)Google Scholar.

Something, but not just anything: de Fontaine had in mind judicial opinions. Although Justinian's Code eschewed precedent following (C 7. 45. 13), it was accepted that “customs and usage” should guide judicial rulings “where we have no applicable written law” (D 1. 3. 32 (Julian)). If an opinion had been repeated it was custom, and so, in the absence of written law, it could be cited as legal authority.

51 Statute of Westminster I 1275 (3 Edw. 1), c. 39: “en conte de decente en le bref de dreit qe nul ne seit oy por demaunder la seisine son auncestre de plus lointein seisine qe del tens le rey Richard, oncle le piere le Roy qe ore est” (“in making the count of the descent [from the last ancestor in seisin] in a writ of right, no one shall presume to trace the seisin of his ancestor beyond seisin at the time of King Richard, uncle to [Henry III,] the father of [Edward I,] the king that now is”). The idea that Richard I's coronation marked the beginning of legal memory was reinforced by Edward I's investigations into the exercise of jurisdictional franchises, which settled that peaceful enjoyment of such a franchise since 1189 would be an answer in a writ of quo warranto: Statute of Quo Warranto 1290 (18 Edw. 1).

52 The association of a statutory limitation date with the limit of legal memory starts to become particularly evident from around 1300 – see De La More v Thwing (1308–09) Y.B. 176, 178; The King v Wickham Breaux (1313) Y.B. 179, 180 – though there are earlier instances: see Brand, P., “Lawyers’ Time in England in the later Middle Ages” in Humphrey, C. and Ormrod, W.M. (eds), Time in the Medieval World (York 2001), 103Google Scholar, where a case from 1247 is cited in which, during pleading, the accession of Henry I appears to be asserted as fixing the outer limit of the prescription period for the acquisition of an easement; and also Brand, “Limitation and Prescription in the Early English Common Law (to c. 1307)” in Dondorp et al., Prescription and Limitation, forthcoming, where there is cited a case from 1241 (de Columbers v de la Ryvere), in which 1135 was used as the date marking the limitation period for a (pre-Provisions of Merton) claim made by writ of right.

57 The question of whether it had been established was for a jury, and jurors were not instructed that a standard fixed amount of time must pass before they could conclude that a custom had been proved beyond living memory. Sixty years was usually (though not always) considered a sufficient amount of time. Sometimes the period would be shorter. A range of instances is set out in Baker, “Prescriptive Customs”.

58 See Coke, 1 Institutes 113b.

59 See Blackstone, 1 Commentaries 77–8. Although it was accepted that local customs had to be reasonable if they were to bind as law – see e.g. Littleton, Tenures, p. 37; also the Case of Tanistry, p. 32 – a binding local custom was enforced as customary law at variance with the common law (see Littleton, Tenures, p. 81). Since the common law itself was understood to be inherently reasonable (a point considered below), a court which enforced a local custom was in effect allowing a practice deemed reasonable in a locality (typically, a manor) to take priority over a custom considered reasonable throughout the realm.
