Finnis thinks that Alexy admits of the possibility of observers calling monstrously evil laws legally valid (Finnis, supra note 17 at 88-89) but notes that the central point of view should be that of participants (Alexy, “Some Reflections”, supra note 19 at 109). Finnis opines that Alexy has failed to challenge Hart’s thesis about the specifically legal point of view of Hart’s participants, who correspond to Alexy’s observers, who recognise as rules what is acceptable by the rule of recognition. Thus, positivists can say that their account of law facilitates an understanding of all perspectives, including that of Alexy’s participants who are interested in legal ideals (Finnis, supra note 17 at 89).

In relation to East Germany see Russell Miller, “Rejecting Radbruch: The European Court of Human Rights and the Crimes of the East German Leadership” (2001) 14:3 Leiden J Int’l Law 653 at 653-63. Miller notes that Radbruch’s Formula has not been used by the European Court of Human Rights, which chose to find, in similar cases on appeal from the German courts, that the use of firearms had been authorized only for serious crimes, and the acts of the accused persons were therefore not justified by various provisions of German law, with the result that Article 7(1) of the European Convention on Human Rights did not absolve them. But the European Court on Human Rights may have sought to avoid the political sensitivities in what would have been taken as an equation of East German crimes with Hitler’s crimes, if Radbruch’s Formula had been invoked.

59. Manfred J Gabriel, “Coming to Terms with the East German Border Guards Cases” (1999) 38:2 Colum J Transnat’l L 375 at 417. While the killing in these cases was not equated with the mass murder during the Nazi regime (see also Rivers, supra note 58 at 249), in 1992, the Federal Supreme Court for Civil and Criminal Matters considered the validity of a provision of the East German Border Law authorizing a border guard to fire his weapon at persons fleeing at the Berlin Wall. They considered the actual practice of shooting in interpreting the scope of the law. They found that the issues were whether the state had gone beyond “the outermost limit set in every country as a matter of general conviction” and whether the conflict between positive law and justice was “intolerable”: see Paulson, supra note 8 at 28.

65. This was challenged in Mack v Attorney General of Canada (2002), 60 OR (3d) 737 (CA). That the court did not consider invalidating the statute has been regretted (Rivers, supra note 58 at 251) though it has also been noted that the constitutional and international norms against racial discrimination might not have been in existence at the time of the statute. See David Dyzenhaus & Mayo Moran, “Mack v Attorney-General of Canada: Equality, History, and Reparation” in David Dyzenhaus & Mayo Moran, eds, Calling Power to Account: Law, Reparations, and the Chinese Canadian Head Tax Case (University of Toronto Press, 2005) 3 at 10.

66. Contrast with the view of Dyzenhaus that such a law is better conceived of as punitive towards a class of individuals and therefore failing in Fuller’s requirement of generality which is a requirement of the inner morality of law or the rule of law. See ibid at 270-76.

74. Alexy makes a different case for human rights which represent the core of justice, as every injustice involves a violation of human rights (Alexy, “Law, Morality”, supra note 19). But my case for acceptance of Radbruch’s Formula in light of acceptance of democratic constitutionalism is a different one.

75. Legitimacy is said to be greater in cases of authorship than ratification, and in turn for ratification over passive acceptance in the form of acquiescence, which is a “suboptimal form of legitimation.” See Jeff King, “The Democratic Case for a Written Constitution” (2019) 72:1 Current Legal Problems 1 at 7-8.

83. This is not commonly discoursed as such. Usually, the link between the constitution and a natural law understanding of rights is made through the argument that inherent uncreated rights have been recognised in the constitution. See, e.g., Juan Cianciardo, “The Culture of Rights, Constitutions and Natural Law” (2013) 8:2 J Comp L 267. For example, Alexy, writing about human rights that have been positivized into constitutional rights, took the view that the positivization did not cause human rights to “vanish.” Rather, human rights remain “as reasons for or against the content that has been established by positivization and as reasons required by the open texture of constitutional rights.” See Robert Alexy, “Constitutional Rights and Proportionality” (2014) 22 Revus: Journal for Constitutional Theory and Philosophy of Law 51 at 62.

84. Alexy recognises that an accommodation of natural law in positive law is still legal positivism (Alexy, “Some Reflections”, supra note 19 at 109-10). Finnis tends towards this as he requires the system itself to provide a juridical basis for regarding otherwise valid rules as legally invalid by virtue of their iniquity (Finnis, supra note 4 at 476).

88. Ibid at 515.

89. 198 US 45 (1905) [Lochner]. This was despite the fact that the majority, through Justice Douglas, declined the invitation to use Lochner as their guide (see Griswold, supra note 85 at 481-82). In Lochner, freedom of contract was found to be guaranteed as part of the ‘liberty’ referred to in the due process clause. This had been criticised as the method by which judges imposed social and economic policies they favoured on the public. See Robert P George, “Natural Law, the Constitution, and Judicial Review” in Robert P George, The Clash of Orthodoxies: Law, Religion, and Morality in Crisis (ISI Books, 2001) 169 at 172.

The view that natural law might have suggested that there exists a right to marital privacy that supports an invalidation of an anti-contraceptive law is ironic as Aquinas’ classical natural law recognises the preservation of species through procreation as natural. See, also, Kirk A Kennedy, “Reaffirming the Natural Law Jurisprudence of Justice Clarence Thomas” (1997) 9 Regent U L Rev 33 at 49.

90. Griswold, supra note 85 at 520.

91. Ibid at 513.

92. George, supra note 89 at 173-74. It has been observed that the philosophical influence upon the founders was the classical natural law theorists rather than the Enlightenment thinkers. See Robert S Baker, “Natural Law and the United States Constitution” (2012) 66:1 Review of Metaphysics 105 at 113. There was also a reluctance to enumerate rights when the proposal for a charter of rights was rejected at the Philadelphia Convention, though a compromise was reached in the guarantees via the amendments. Baker notes that the phrasing in the First Amendment suggests that the rights are not created by the amendments but implies that they pre-exist the constitution. This contrasts with the expression, for example, in the French Declaration of the Rights of Man and of the Citizen, which focuses on state sovereignty and the law being an expression of general will, or the Venezuelan Constitution of 1811 which speaks of a renunciation of unlimited liberty and license and the social contract being an assurance to the individual of the enjoyment of his rights (Baker, ibid at 121-23). Notably, also, there is no contradiction between recognising the natural law foundations of the American Constitution and the rejection of judge-made constitutional law. See Baker, ibid at 130, citing Bowers v Hardwick 478 US 186 (1986). See also, Kennedy, supra note 89 at 47.

93. In particular, the idea of substantive privacy or the freedom from governmental interference in fundamental decisions is hardly likely to have the support of some natural law theorists.

108. Alexy, “Dual Nature”, supra note 35 at 176. See also Alexy, supra note 106 at 287. Notably, Alexy points out that the position that Beyleveld and Brownsword term ‘idealism’ has inbuilt checks which restrain the wide-ranging effects of injustice on legal validity. Their ‘theory of restraint’ stipulates for a collateral moral obligation to comply with immoral rules, and a provisional legal-moral obligation in the case of controversial rules, in order to balance the moral costs of compliance with the moral costs of non-compliance. Alexy does not agree with this mode of taking away legal validity but recreating a moral obligation as he thinks it is tantamount to treating the consequences of a mistake instead of curing the disease.

See Barber, supra note 118 at 198. Pope Pius XI emphasized that social activity ought to “furnish help to the members of the body social, and never destroy or absorb them.” See Pope Pius XI, Quadragesimo Anno: Encyclical of Pope Pius XI on Reconstruction of the Social Order (1931) online: http://www.vatican.va/content/pius-xi/en/encyclicals/documents/hf_p-xi_enc_19310515_quadragesimo-anno.html (accessed on 23 July 2020) at para 79, a point also noted by Pope John Paul when he suggested that a community of a higher order ought not interfere in the internal life of a community of a lower order, and should be supportive and coordinating all to the common good. See Pope John Paul II, Centesimus Annus (1991) online: http://www.vatican.va/content/john-paul-ii/en/encyclicals/documents/hf_jp-ii_enc_01051991_centesimus-annus.html (accessed on 23 July 2020) at para 48.

See also Patrick McKinley Brennan, “Subsidiarity in the Tradition of Catholic Social Doctrine” in Michelle Evans & Augusto Zimmermann, eds, Global Perspectives on Subsidiarity (Springer, 2014) 29 at 35. The term ‘subsidiarity’ was coined by Italian Jesuit, Luigi Taparelli.

See also Nicholas Aroney, “Subsidiarity, Federalism and the Best Constitution: Thomas Aquinas on City, Province and Empire” (2007) 26:2 Law & Philosophy 161 at 177-79. Indeed, subsidiarity has been regarded as incompatible with Aristotelian ideas which treated the city-state as primordial and did not grant autonomy to inferior levels.

High regard remains for individual freedom; see Robert A Sirico, “Subsidiarity and the Reform of the Welfare of the Nation State” in Michelle Evans & Augusto Zimmermann, eds, Global Perspectives on Subsidiarity (Springer, 2014) 107 at 111. Subsidiarity assists individuals and groups when they are unable to accomplish something on their own, with a view to achieving their emancipation by fostering freedom and participation through assumption of responsibility, according to Pope Benedict XVI.

See Pope John XXIII, Pacem in Terris: Encyclical of Pope John XXIII on Establishing Universal Peace in Truth, Justice, Charity, and Liberty (1963) online: http://www.vatican.va/content/john-xxiii/en/encyclicals/documents/hf_j-xxiii_enc_11041963_pacem.html (accessed on 23 July 2020) at paras 140-41.

153. This is, strictly speaking, different from the issue of a common good at the international level, in relation to which Carozza notes the general difficulty in applying subsidiarity in the context of international law in view of the fragmentation of international law and the lack of a uniform, coherent notion of the common good. See Paolo G Carozza, “The Problematic Applicability of Subsidiarity to International Law and Institutions” (2016) 61:1 Am J Juris 51 at 55-60. There is no presumption in favor of localism or devolution as such, as subsidiarity calls for intervention and assistance as well as immunity and autonomy ( ibid at 63).

Moreover, the way the margin of appreciation has been applied is difficult to square with subsidiarity, for example when a broader margin has been allowed when issues relate to protection of morals and national security, but less leeway has been applied to matters of discrimination, freedom of expression, or rights to family life.
