SOURCES OF LAW

Abstract

This article aims to clarify what is meant by “a source of law” argument. A source of law argument justifies an action by showing that it has as its legal basis the best interpretation of a rule, principle or value identified in a material source of law. Such an argument is authority-based in that it appeals for its correctness to a collective decision to adopt a particular rule. The identification comes from an analysis of the practices within a specific legal community. The concept of “a rule of recognition” is not helpful since it glosses over the contestability of what is a source of law and its revisability over time. In a second part, the article illustrates the dynamics of change by reference to the status of EEC/EU law in a number of national laws and the 1966 Practice Statement on precedent in the House of Lords.

Though one may be able to treat the wording as fixed, the legal significance is a matter of interpretation and the Fallnorm (the rule to be applied in the case) is only the product of that reasoning process.

19 It might be objected that “values” could not be directly applied as sources of law.

35 “Rules are conventional social practices if the general conformity of a group to them is part of the reasons which its individual members have for acceptance; by contrast merely concurrent practices such as the shared morality of a group are constituted not by convention but by the fact that members of the group have and generally act on the same but independent reasons for behaving in certain specific ways” (Hart, Concept of Law, p. 256).

37 More correctly, we probably have to look at what the influential members of the legal community do: see Paterson, A., The Law Lords (London 1982)CrossRefGoogle Scholar on who influences the Law Lords; Paterson, A., Final Judgment (Oxford 2013), ch. 6Google Scholar.

43 The most famous exception is article 1 of the Swiss civil code: “If no command can be taken from the statute, then the judge shall pronounce in accordance with the customary law, and failing that, according to the rule which he as a legislator would adopt.

La non applicazione [del diritto interno] deve essere evitata solo quando venga in rilievo il limite, sindacabile unicamente da questa Corte, del rispetto dei principi fondamentali dell'ordinamento costituzionale e dei diritti inalienabili della persona.”
