Philosophical Lens (The Normative Theories, etc. Continued)

While objectives 1–3 have been dealt with in the chapters so far, this chapter is dedicated to objective 4. That is to say, whether we can identify a certain common horizontal (or rather a specific) pattern in referring to these terms of ethics and morality, and whether we can thus identify an ethical spirit based on an analysis of these legal texts; or whether we have to ascertain a gap, which has to be filled by other means?


Ethical Approach Identified in EU Legal Documents
While objectives 1-3 have been dealt with in the chapters so far, this chapter is dedicated to objective 4. That is to say, whether we can identify a certain common horizontal (or rather a specific) pattern in referring to these terms of ethics and morality, and whether we can thus identify an ethical spirit based on an analysis of these legal texts; or whether we have to ascertain a gap, which has to be filled by other means?
First, we have to shed some light on the notion of 'spirit', a term that can have manifold meanings. According to the Collins Birmingham dictionary, the spirit of a legal provision "is the way that it was intended to be interpreted or applied", 1 and according to the Oxford dictionary "the real meaning as opposed to lip service or verbal expression (the spirit of law)". 2 Often this intention of the authors of a legal provision can be contrasted to the literal meaning, the mere wording. A famous example for this opposition of "wording vs. spirit" can be found in William Shakespeare's "The Merchant of Venice", 3 where the promise to give a "pound of flesh" in case a loan cannot be repaid, in the end is solved as follows. As the agreement did not mention blood, hence, there would only be a right to have this "pound of flesh", if no blood would be shed. 4 However, this book is based on an understanding, where the notion of 'spirit' surpasses the mere 'intention' of a legal provision in various ways. First, this book refers to "the ethical spirit of EU law", hence, a legal system and not only a single legal provision. Second, for the author, 'spirit' is more than just the intention. It is the holistic coming together of different elements, or as Montesquieu called it, the "relations [which] together constitute what I call the Spirit of Laws". 5 When analysing " [h]ow values come to matter at the European Commission", Jim Dratwa has referred to a 'lattice', a "set of bodies and texts, of products and processes". 6 While the author of this book fully acknowledges the difficulty in defining the notion of 'spirit', this book is based on the following understanding: the intention of the authors of a legal system, which is reflected in a lattice of various different provisions.
In a metaphorical sense, this 'spirit' 7 can be described as a ghost that maybe cannot be seen, but which is nevertheless present in terms of this lattice; or, as mentioned above, the discovery of a common approach which can serve as a basis of understanding of the underlying philosophy of EU law. 8 The reason, why this definition includes "the authors of a legal system" (plural) and not "the legislator" is simply because we have seen several authors in Sects. 3.1-3.3.4. From the MS as "Masters of the Treaties", the EP and the Council (i.e. the ordinary legislative procedure), the CJEU (case-law), and finally to the MS in implementing directives, to name but the most important ones. The spirit of a legal system obviously can change over time. The spirit of EU law in its infancy was different at the beginning (starting with coal and steel, spilling over to the general economic field), compared to what it is today (also comprising the political field and entailing human rights and values). It is also relative to those different provisions and processes. This relativity is reminiscent of the 'relation' aspect, which has also been stressed by Montesquieu. In his famous book, the 'spirit of laws' ('De L'esprit des Loix' 9 ), he wrote that the spirit of laws "consists in the various relations which the laws may have to different objects". 10 In that regard he mentioned the "nature and principle of each government", "the climate of each country", the "relation to the degree of liberty which the constitution will bear, to the religion of the inhabitants, to their inclinations, riches, numbers, commerce, manners, and customs". 11 In addition, he continues: "These relations I shall examine, since all these together constitute what I call the Spirit of Laws". 12 These relations 13 add up to this lattice that reflects this spirit, in our case, 'the ethical spirit of EU law'.
To begin with, some introductory remarks. In the context of the above-mentioned determination of the substance of ethics, some categories are more useful to extract this ethical spirit, others less so. The most fruitful categories were those where ethics was used as a supportive argument [2.], or where the determination took place via codes of conduct [5.], especially if these codes of conduct entailed certain principles, as well as if the content of ethics was determined in the relevant legal document itself [7.]. If ethics was only used as an argument against interference from the EU [1.], if 'only' a parallel ethical assessment (besides the legal one) was opened [3.], or if substance wise ethics has not been determined at all [8.], then these categories obviously are less rewarding. Obviously, we cannot harvest any useful 'ethics fruits', if the determination takes place elsewhere, i.e. in case of ethics committees [4.] and in reference to other documents [6.]. The same holds true if in case of codes of conduct [5.], these documents, in the future, will be drafted at a different level (e.g. by MS or companies). The respective contribution of these categories to our quest for the ethical spirit of EU law can be displayed as follows (see Table 4.1).
Hence, in the following, the findings of Chap. 3 will be contrasted with the practical philosophical basics, as covered in Chap. 2. The questions to be answered are the following: 11 Ibid. 12 Ibid. 13 In CJEU Achmea, C-284/16, paras 33-34, in the context of the autonomy of EU law and the EU's common values, the Court referred to "a structured network of principles, rules and mutually interdependent legal relations".
• Question No 1: In EU law's references to ethics, can we identify any philosophical theory at all? • Question No 2: If yes, would this comprise one or more philosophical theories? • Question No 3: If yes, should this be understood as an unconditional reference to one or more philosophical theories, or only as pointing towards a certain idea?
Without wishing to broach fundamental philosophical issues, it should be emphasised that these three normative theories presented in Chapt. 2 can also overlap. As mentioned earlier, deontology rather focuses on an act, consequentialism on its consequences, and the virtue ethics puts an emphasis on the agent itself. 14 Hence, the peculiarity of these three theories is the way in which "good behaviour" is argued. Of course, these three theories arguing in a different way, in the end can come to the same solution. For example, it can be considered good to help children, e.g. to cross a dangerous street. This can be considered intrinsically good (deontology), one can also argue this as in line with consequentialism (the outcome that a child that has not been endangered in this situation), but one can also see it as a positive trait to help children, whereby this inner attitude also manifests itself in the outside (virtue ethics). While a division into these three normative ethical theories is prevailing in literature, one can question if this sharp distinction is the best approach possible. However, as it is not the objective of this book, this question can be left aside. 15 When now, hereinafter, certain examples will be assigned to the three normative theories, the following has to be emphasized: As far as this can be judged on the basis of the research conducted, the various 'authors' of the EU's legal system have never explicitly referred to one of these normative theories. Hence, question No 1 (identification of any philosophical theory) can only be answered with regard to implicit references. Therefore, the following 'disclaimer' has to be stressed. The following examples can be interpreted as pointing into a certain direction, but it is not the case that sometimes other interpretations would not be possible.
As mentioned above, according to deontology actions are intrinsically right or wrong, irrespective of their consequences.
• In the field of patentability of biotechnological inventions, we seem to have such a deontological approach, when it is stated that "there is a consensus within the [EU] that interventions in the human germ line and the cloning of human beings offends against ordre public and morality". 16 This consensus seems to refer to what is intrinsically wrong. As it is against morality, (a) processes for cloning human beings, (b) processes for modifying the germ line genetic identity of human beings, as well as (c) uses of human embryos for industrial or commercial purposes, "shall be considered unpatentable". 17 Especially this stance against commodification of human beings in statu nascendi can also be seen as a deontological approach, reminiscent of the concept of human dignity. This is in line with the EP statement we have seen on surrogacy. According to this statement, surrogacy "undermines the human dignity of the woman since her body and its reproductive functions are used as a commodity". 18 • A similar deontological and anti-commodification approach can also be found with regard to animals, when the killing of seals "for commercial reasons" is seen as intrinsically wrong due to "public moral concerns", whereas this is not the case for seal hunts traditionally conducted by Inuit and other indigenous communities. 19 Hence, to some extent also a consequentialist approach. • Another noteworthy example concerns supply chain due diligence obligations and the import of tin, tantalum and tungsten, their ores, and gold, which shall not be imported from conflict-affected or high-risk areas, in particular in the African Great Lakes Region, as this would contravene "ethical mining". 20 • However, the most important example in this regard is the one that "[a]nimals have an intrinsic value which must be respected". 21 This deontological attitude corresponds with what we have seen in the context of animal transports 22 and animal experiments, i.e. the statement that "man has a moral obligation to respect all animals and to have due consideration for their capacity for suffering and memory". 23 In addition, we have seen similar approaches with regard to animals in the context of mass slaughtering. 24 • In addition, the statement on an ethical accountability of researchers "towards society as a whole" 25 can be interpreted as a deontological approach. All these examples point towards a deontological understanding and are, as we have seen, closely related to human dignity, or the intrinsic dignity of animals. 27 As mentioned above, according to consequentialism actions are morally right or wrong depending on the quality of the consequences of action.
• The request "to ensure the ethics of transplantation by adopting measures to eliminate 'transplant tourism'" 28 could be interpreted as a consequentialist approach, as the ethical quality of the action of the addressed states is based on the outcome of their action, i.e. the elimination of transplant tourism. • In addition, the Korea agreement defines 'ethical business practices' (i.e. the title of this provision) with regard to the pharma industry by its outcome, according to which the contracting parties "shall adopt or maintain appropriate measures to prohibit improper inducements by manufacturers and suppliers of pharmaceutical products or medical devices to health care professionals or institutions". 29 • The outcome is also the basis for the following example, here to reduce ethical concerns. Moreover, it is an example of the consideration of animal welfare with a consequentialist approach. The outcome in the field of novel food is, where possible, the avoidance of the duplication of animal testing, as "[p]ursuing this goal could reduce possible animal welfare and ethical concerns with regard to novel food applications". 30 While these examples display a consequentialist approach in order to determine moral correctness and falseness of action, we also have consequentialist examples elsewhere in EU law.
• The effectiveness of EU law, often even in other language versions referred to as "effet utile", has become of paramount importance in the case-law of the CJEU. In essence, it states that the provisions of EU law must be interpreted and applied in such a way that they fulfil their practical purpose and have practical effect. On this basis, the requirement of the practical effectiveness of EU law serves the CJEU as an explanatory element with regard to practically all institutes of EU law and in this respect runs like a red thread through the case-law of the Court. 31 In this case-law, the key interpretative approach of the Court is the outcome, the assertion of EU law. Although, this 'effet utile' approach finds its limitations, as there has to be an "appropriate balance between Member State autonomy and the 'effet utile' of EU law". 32 When analysing the explicitly mentioned "effet utile", Advocate General (AG) Kokott referred to "the spirit and purpose of" the relevant provisions of 27 For various ethical approaches concerning animals, see the various contributions in Beauchamp and Frey (2014 EU law. 33 As mentioned above, this 'effet utile' case-law is not directly related to ethics and morality. As we have seen above, 34 the Court tackles 'sensitive issues of ethical nature' with a purely legal methodology, which, nevertheless, still renders a decision on this ethical topic. Hence, the 'effet utile' case-law can also be of indirect relevance for our topic. • Apart from this supreme 'tool of interpretation', another (non-ethical/moral) consequentialist approach of EU law can be found in case of impact assessments. Impact assessments have already been mentioned as one example indicated in literature in the context of consequentialism. 35 According to Birnbacher, they are not required to assess the outcome of any possible action, but are limited to decisions with far-reaching consequences, as in case of national or supranational legislators. 36 In EU law, impact assessment is one of the "tools for better law-making", in order to "reach well-informed decisions", respecting, amongst others, fundamental rights and "based on accurate, objective and complete information". 37 In essence, an impact shall "cover the existence, scale and consequences of a problem". 38 Such an impact assessment can also be required in the context of the precautionary principle, for instance when approving active substances resulting in losses of honeybee colonies. 39 All these examples point towards a consequentialist approach, both relating to ethics and morality, but also elsewhere in EU law (effet utile, impact assessments).
Virtue ethics, sometimes understood rather as a supplement than a basis of normative ethics, 40 puts an emphasis not on the intrinsic quality of the action or its consequences, but on the agent itself. 'Virtues' are character traits, which must also be reflected in corresponding behaviour. 41 As mentioned above, sometimes virtue ethics cannot avoid establishing principles for its part (e.g. the virtue of justice may require principles of justice). 42 'Integrity' has been described as "an important personal characteristic in ethical systems based on virtue and moral character". 43 • In the Georgia agreement, we have seen one example for the close link of ethics (precisely, the 'Blueprint on Customs ethics') and "the highest standards of integrity".  Birnbacher (2013, pp. 194-195 Birnbacher (2013, p. 305). 41 Birnbacher (2013, p. 295). 42 Birnbacher (2013, p. 304). 43 Forrest (2002, p. 441). 44 See at note 52.
• The most important examples referring to integrity can be found in the field of lobbying. 45 Integrity was mentioned for several 'targets' of lobbying, such as the EP, the EC, 46 EU staff, and even for the CJEU, as well as for experts ("ensure the highest level of integrity of experts"). 47 However, it has not been addressed for the 'actors' of lobbying. 48 • Other terms we have seen in the context of lobbying, have been as follows: accountability, dignity, diligence, discretion, disinterest, honesty, impartiality, independence, loyalty, objectivity, openness, responsibility, and transparency. Some of these terms rather fall in the category of legal principles (accountability, diligence, impartiality, independence, objectivity, responsibility, transparency), while (human) dignity is a value 49 and discretion, disinterest, openness, honesty, integrity and loyalty could also qualify as virtues. 50 • Furthermore, Horizon 2020 addresses "research integrity", 51 as well as Directive statutory audits, which requires statutory auditors to adhere to "the highest ethical standards". 52 • In the context of the EU 'ethics directives', 'integrity', besides ethics, was the most important key term, mainly occurring in the field of 'accounting & finance', followed by the 'health' field. 53 • As already mentioned earlier, the three notions of 'values', 'principles' and 'virtues' "can and do overlap". 54 While Art 2 TEU explicitly addresses values, the second sentence of this provision refers to "a society [in the MS,] in which pluralism, non-discrimination, tolerance, justice, solidarity and equality between women and men prevail". For instance, tolerance and solidarity could also be virtues, where justice is even a cardinal virtue. 55 All these examples can be seen to point towards virtue ethics, if they are also reflected in the corresponding behaviour. Consequently, we have seen examples pointing into the direction of all three normative theories, which answer the abovementioned three questions. However, as this book follows an inductive approach, likewise, in the following, examples referring to minimal ethics, principlism and communitarianism will be addressed.
Minimal ethics only defines moral norms for a core, while this claim does not exist for the periphery.  Williams (2010, p. 257). 55 See at note 105.
• The most prominent example, in this regard, is the field of patentability of biotechnological inventions, a much-contested issue, which we have already seen at various times throughout this book. This has been solved in the following way: Art 6 of this directive defines a core in para 2, where MS and the EP where able to reach a compromise; in the words of AG Cruz Villalón: "a minimum, Union-wide consensus for all Member States". 56 This compromise defined at EU level comprises cloning of humans, modification of the germ line genetic identity of humans, uses of human embryos for commercial purposes, as well as modification of the genetic identity of animals. Obviously, there was no consensus concerning other equally sensitive issues, hence, para 1 of this provision delegates the question of answering the unpatentability to the national level, where the commercial exploitation of inventions has to be assessed against the notions of "ordre public or morality". This approach of a minimal ethics at EU level for a core, capable of consensus, and a possible divergent national approach at the periphery, could serve as a role model for other fields. • This minimum consensus of this 1998 directive has been adopted, in identical terms, in the 2014 agreement with Ukraine. 57 A similar approach is adopted in Horizon 2020, where, under the heading of 'ethical principles', research fields reminiscent of, however not identical to, Art 6(2) Directive Biotech shall not be financed. 58 • A minimum approach, however of a different kind, can be seen in a resolution, which states that in case sanctions cannot "bring about a change of regime in a particular country, or at least a major change in the policy of that country's government, their imposition may also serve simply as an expression of moral condemnation". 59 This is not a true minimum approach which achieves consensus in a core and leaves open questions at the periphery, rather the primary objective (i.e. change of regime) has failed, that is why only moral condemnation remains.
All these examples display a 'minimal ethics' approach. Such an approach might be suitable for areas, where a consensus amongst MS (and the EP) can only be achieved in a (united) core, while the periphery is left to potentially diverse solutions in the MS.
Principlism determines ethics in a substantive way (cf. in the field of medical ethics, Beauchamp and Childress), where ethics is defined based on a certain number of moral principles (e.g. autonomy, beneficence, nonmaleficence, and justice). As mentioned earlier, 60 we can distinguish a legal and a philosophical understanding of 'principles'.
• Against the background of the heated debates on investment protection, Art 8. multilateral investment tribunal. The independence of its members, as well as the avoidance of both a direct or indirect conflict of interest. 61 The 'Joint Interpretative Instrument' stresses "independence and impartiality, the absence of conflict of interest, bias or appearance of bias". 62 • Likewise, the Korea agreement also refers to the following principles in order to achieve "ethical practices by manufacturers and suppliers of pharmaceutical products and medical devices and by health care providers on a global basis": openness, transparency, accountability and non-discrimination in health care decision-making. 63 • These principles overlap with those which have been qualified as legal principles above in the context of lobbying: accountability, diligence, impartiality, independence, objectivity, responsibility, transparency. Again, the question of distinguishing virtues from legal as well as philosophical principles remains a challenge. • One of the most comprehensive examples can be found in the field of nanosciences.
The annex of this code of conduct, which is "based on a set of general principles", mentions the following ones. 64 Meaning (which comprises comprehensibility for the public, respect for fundamental rights, as well as acting in the interest of the well-being of individuals and society); sustainability (referring to the United Nation's Millennium Development Goals, as well as avoidance of harm or creation of "biological, physical or moral threat to people, animals, plants or the environment, at present or in the future"); precaution (basically referring to the EU's precautionary principle 65 ); inclusiveness (principles of openness to all stakeholders, transparency, access to information, as well as stakeholder participation in decision-making); excellence (also comprising "integrity of research"); innovation; as well as accountability (with regard to "social, environmental and human health impacts […] on present and future generations"). These "general principles" address both the legal as well as the ethical sphere, without providing a clear distinction. • As we have already seen elsewhere, in the field of biotechnology, reference is made to the national level of MS within the context of "ethical principles", 66 while in the same directive we find an undetermined reference to "basic ethical principles" 67 for the question when the EGE can be consulted.
All these examples can be attributed to principlism. From a theoretical perspective, one could criticize the fact that it is left open whether these principles are purely legal ones, purely philosophical ones, or a combination of both. Yet, from a pragmatic 61 It is worth mentioning that apart from these substantive principles in para 1; paras 2-4 provide procedural safeguards in this respect. 62 OJ 2017 L11/3 (4); emphases added. See also the Statement by the Commission and the Council on investment protection and the Investment Court System ('ICS'), on p. 20. 63 Agreement Korea, Annex 2-D, Art 1(e). 64 EC recommendation nanosciences, Annex, pt. 3. 65 Recently: GC BASF Agro, T-584/13; for further details, see Frischhut and Greer (2017, 331-333). 66 Directive Biotech, recital 39: "ethical or moral principles recognised in a Member State". 67 Directive Biotech, recital 44. perspective, this approach has to be welcomed, as the content of ethics is more clearly determined.
In summary, it can be said that in EU law's references to ethics, we can identify normative theories (question No 1), although only implicit and no explicit ones, covering all three proponents (question No 2). All the examples we have seen cannot be understood as unconditional references, but only as pointing towards these normative theories (question No 3). Can we identify a certain common horizontal (or rather a specific) pattern in referring to these terms of ethics and morality? We have seen different approaches referring to the normative theories of deontology (putting an emphasis on human dignity), consequentialism (with examples in the field of ethics and morality, but also elsewhere in EU law, such as effet utile and impact assessments), and virtue ethics (especially, but not only in lobbying), as well as minimal ethics (Directive Biotech, etc.), and principlism (lobbying and nanosciences). There is clearly no horizontal, but a specific approach in addressing different needs in different fields, from independence of members of investment tribunals to research integrity in nanosciences. Hence, we can address both an ethical spirit in the sense of the intention of the various authors of EU law, which is reflected in a lattice of various different provisions, as well as a gap that still needs to be filled. So far, the examples covered those authors authorized to issue binding and non-binding legal provisions, not specifically tasked to deal with ethics. Accordingly, we will now turn to an entity that, while 'only' having an advisory function, is specifically tasked to deal with ethics.

EGE Opinions
The practical impact of EGE opinions can, amongst others, 68 be seen from the EU's research funding programme Horizon 2020, where the relevant regulation states that "[t]he opinions of the [EGE] should be taken into account". 69,70 In the field of patentability of biotechnological inventions, the already widely covered directive states that the EGE "evaluates all [sic!] ethical aspects of biotechnology". 71 This directive dates from 1998, hence, the year after the EGE's establishment. 68 In addition, several other regulations and directives, as well as courts, e.g. the CJEU and the European Court of Human Rights (ECtHR), as well as AG at the CJEU have referred to EGE opinions; for further details, see Pirs (2017, p. 32). This chapter has been drafted at the same time as the following paper; hence, certain parts can overlap: Pirs and Frischhut (2019, forthcoming

EGE History, Institutional Structure and Opinions
Due to rapid scientific developments in biotechnology and genetic engineering in the late 1980s and early 1990s, there was need for an institutionalized framework facilitating debate and addressing public concern as to ethical implications. 72 Hence, in April 1991 the EC stated that there is a need for a "consultative structure on ethics and biotechnology". 73 The Group of Advisers on the Ethical Implications of Biotechnology (GAEIB) was created on 20 November 1991. After the first mandate of two years, the EC addressed the necessity "to clarify further value laden issues in relation to some applications of biotechnology", hence to "reinforce the role of the [GAEIB]". 74 After the mandate had expired on 31 July 1997 75 and the legislative process leading to 'Directive Biotech' was in full swing, 76 the EC on 16 December 1997 decided to replace the GAEIB by the EGE, "extending the Group's mandate to cover all areas of the application of science and technology". 77 12.12.199712.12. [EGE mandate I 1997. 80 That is to say, as of the second mandate (see Table 4.2), Mohr et al. (2012, p. 107). 81 Plomer (2008, p. 841). 82 The EGE's website can be accessed via http://ec.europa.eu/research/ege/index.cfm. direct and regular access to the EC president (Juncker). 83 For an overview of the EGE's development, see Table 4.2.
Moreover due to the increasing role of 'good governance', 84 the already mentioned horizontal rules on the creation and operation of EC expert groups also apply to the EGE; as already mentioned, these rules strive for a balanced composition of expert groups and also comprise rules on conflict of interest, in order to "ensure the highest level of integrity of experts". 85 Likewise, as for all expert groups giving advice to the EC, the core principles of 'quality, openness, and effectiveness' apply to the EGE. 86 Under the current mandate, the EGE is tasked "to advise the Commission on ethical questions relating to sciences and new technologies and the wider societal implications of advances in these fields". 87 The members are appointed by the EC president, based on a proposal from the Commissioner for research, etc. 88 The EGE, which "shall be independent, pluralist and multidisciplinary", is composed of 15 members serving in personal capacity, and demonstrating "a high level of expertise and pluralism"; furthermore, the mandate strives to establish a geographical balance, as well as a balanced representation of relevant know-how and areas of interest". 89 In its 1997 resolution concerning the GAEIB, the EP had criticized that so far, "too much attention has been paid to the interests of research and not enough to the possible effects on society". 90 Today, besides a balance of qualities, gender and geographical distribution, the current mandate requires "independent advice of the highest quality", "combining wisdom and foresight", as well as "internationally recognised experts, with a track record of excellence and experience at the European 83 Compared to former president Barroso, president Juncker also took a different approach in another field, by "scrapping" the role of the Chief Scientific Adviser (CSA); see Panichi (2015).  (2002) Pirs and Frischhut (2019, forthcoming) and global level". 91 Furthermore, one of the criteria mentioned is membership in national ethics councils, 92 in order to establish this vertical link between the EGE and national ethics committees. 93 This networking is also related to the international level, in particular the World Health Organisation (WHO), the United Nations Educational, Scientific and Cultural Organisation (UNESCO), and the Council of Europe. This networking is important in terms of exchange of best practice (in either direction).
Most important in terms of qualification, the mandate requires the following 94 : The Members shall reflect the broad cross-disciplinary scope of the group's mandate, embracing philosophy and ethics; natural and social sciences; and the law. However, they shall not [!] perceive themselves as representatives of a particular discipline, worldview, or line of research; they shall have a broad vision which collectively reflects an understanding of important ongoing and emerging developments, including inter-, trans-, and multi-disciplinary perspectives, and the need for ethical advice at the European level.
This requirement, more precisely, this rejection of the possibility of sending representatives of a certain political or ideological direction must also be seen in the light of the criticism that in 2005, many members were too closely linked to the Catholic church. 95 In terms of the inter-institutional role, before the transition from the GAEIB to the EGE, the EP had called for an increasing role on the composition of the new members. 96 These tensions must be seen against the background of fundamental questions about the role of morality in EU law, precisely "the content of any putative European moral norms and the institutional mechanisms through which morally charged EU policy should be decided", as well as the EP's veto against the first draft of 'Directive Biotech'. 97 However, as mentioned above, the EGE's task is to advise one institution, namely the EC. 98 Plomer (2008, p. 842). 98 Quoting former EC president Jacques Santer, in literature (Mohr et al. 2012, p. 107) the EGE was referred to as "the servant of 'European decision-makers', not solely the Commission"; however, in formal terms it is clearly attached to the EC. importance". 99 Once an opinion has been adopted, besides the general publication, the opinion has to be transmitted to the EP and the Council. 100 In terms of the intra-institutional role, the current mandate states "the EGE shall establish close links with Commission departments concerned by issues the Group is working on", 101 hence, a more prescriptive and less aspirational ('may') language, as this was the case earlier. 102 Links with external representatives have to be agreed with the Commission's representative, 103 while previously this was a prerogative of the EGE itself. 104,105 Finally, as Plomer has emphasized, 106 the EGE does not have a 'president', but a 'chairperson' only; while the first mandate had referred to a chairperson, the second mandate 'upgraded' this job to an EGE 'president', with mandates No 3 to 5 again only referring to a chairperson. 107 While legally speaking this might not change a lot, one should never underestimate the symbolic meaning of such wording. 108 The EGE develops their opinions and standpoints in a collaborative way, seeking consensus amongst its members, while leaving open the possibility of dissenting opinions, 109 whereas the discussions are confidential. 110 So far, the EGE has deliv-99 EGE mandate V 2016, Art 3. However, the EGE has also accepted requests by other institutions (especially in case of a political standstill), followed by an official request of the EC (e.g. in case of EGE opinion No 27, on energy). 100 EGE mandate V 2016, Art 5(8). 101 EGE mandate V 2016, Art 5(7); emphasis added. Having access also to other DGs can be important in terms of the impact of the EGE's activities. 102 Plomer (2008, p. 846 (1); EGE mandate V 2016, Art 5(2). 108 It seems that the EGE has always enjoyed sufficient independence in its work. Göran Hermerén, past president and chairperson of the EGE "[does] not recollect any attempt from BEPA or the Commission to interfere with our work, nor to suggest or put pressure on us to change something in a draft EGE report" (personal communication). 109 EGE mandate V 2016, Art 5(6) and (8), "as a 'minority opinion'". See for instance the dissenting opinion of Günter Virt on the controversial issue of patenting of human embryonic stem cells, in EGE opinion No 16 (European Group on Ethics in Science and New Technologies (2002, p. 19)). 110 EGE mandate V 2016, Art 5(10). These internal EGE documents cannot be accessed, "even from within the Commission"; Mohr et al. (2012, p. 109). ered 30 opinions, as well as statements 111 and reports. 112 EGE opinions 113 have been mentioned in several EU legal documents. 114 They shall include a set of recommendations and shall be based on an overview of the state of the art of sciences and technologies concerned, as well as a thorough analysis of the ethical issues at stake. 115 The opinions are usually structured in the following three parts 116 : the first part consists of recitals of the reference texts, which form the starting point (e.g. request by EC president, relevant EU law, relevant international law, primary scientific texts, relevant previous EGE opinions, expert reports and roundtable hearings). The second part consists of three sections, which provide the scientific, legal and ethical backgrounds to the opinion, and the third part presents the opinion with recommendations. 117 Since the beginning, EGE opinions have increased in both scope (from bioethics to sciences and new technologies) and size (from six pages to typically around 100 pages). 118 While some argue that theoretically the EGE is not formally bound to the CFR, 119 there are various references in EGE opinions to this key human rights document, as we will also see in the following.

Key Findings
As it is the EGE's specific task "to advise […] on ethical questions", it remains to be seen how many of the gaps concerning the EU's ethical spirit within the lattice identified so far can be filled based on the findings from the EGE's opinions. Thus, in a similar way as Sect. 4.1, this chapter is dedicated to objective 4, which is to say to answer the question whether the EGE substantiates its ethical reasoning on one of the three normative theories. 111 Statements or other forms of analyses can be produced, if operational circumstances require that advice on a particular subject should be given more quickly than in case of the adoption of an opinion (this should be followed, if necessary, by a fuller analysis in the form of an opinion); EGE mandate V 2016, Art 5(9). 112 According to Busby et al. (2008, p. 840), the EGE was asked to give an opinion on the CFR, however declined to do so and, instead, gave the following report: European Group on Ethics in Science and New Technologies (2000). 113 For a detailed analysis of their impact on the legislative procedure, see Busby et al. (2008)  This chapter is based on a research project, where the research design has been developed by the author, the research itself conducted as well as the research design further specified by Matthias Pirs, 120 and his Master thesis having been supervised within the 'Integrity Research Group' by Lorenzo Pasculli (now: Coventry University) and the author.
With regard to the methodology, 121 this project also took an inductive approach, coding 122 the 1205 pages of the 29 EGE opinions with the aim of deriving 'rules of prediction' in an explorative way. 123 The categories were formed based on a latent analysis, the 'interpretative reading' of the text, so to speak. The opinions where then screened, using the MAXQDA software, which moreover allows to eliminate code redundancies. 124 As mentioned above, for the first time, the third mandate of the EGE (2005-2010) was based on a formal decision, hence increasing EGE's legitimacy. The research has revealed that starting from the second half of this mandate, the EGE refers to our three normative theories, that is to say mainly since opinion No 23 (issued on 16.01.2008), until opinion No 29 (issued on 13.10.2015). 125 Besides the new (and formally strengthened) mandate, the EGE left its initial turf of biotechnology and bioethics, and moved on to new fields of technological developments in agriculture, energy, information and communication technologies (ICT), security and surveillance, and citizen participation in new health technologies. 126 In quantitative terms, 127 the total references to deontology prevail (37), followed by virtue ethics (12) and consequentialism (10), with EGE opinions No 25 on 'synthetic biology' and No 28 on 'security and surveillance technologies' exhibiting the largest accumulation of hints to one or more of these three normative theories, 18 120 Pirs (2017). 121 For further details on the methodology and the limitations, see Pirs (2017, pp. 40-45). Concerning these opinions (in EN), this project applied a qualitative content analysis (QCA) and took a mixed qualitative (assigning code categories in the relevant materials) and quantitative (analysing and interpreting category frequencies) approach. Concerning the footnote references to potential schools of thought, the QCA mainly considered those, "which were primarily referred to in the main line of reasoning (in-text citation or direct references) in the opinions". In other words, the QCA excluded standalone footnote references, if they could not be related to one of the normative theories; Pirs (2017, p. 44). 122 The coding process contained the following steps: reading opinions, inductive coding, lexical search, refining categories, classification, and finally narrowing down to the results, presented in the following; for further details, see Pirs (2017, pp. 43-44). 123 The author would like to thank Nils-Eric Sahlin for pointing to the fact that an inductive method cannot lead to a theory. 124 Pirs (2017, p. 42). As mentioned above (Table 4.2), for opinion No 30 see Pirs and Frischhut (2019, forthcoming). 125 Opinion No 30 is on the 'future of work'. 126 Pirs (2017, p. 49). 127 It has to be emphasized that sometimes it could be the case that, for instance, three hits occur on the same page of the same opinion, while in other cases three hits occur in different parts of the same opinion, or in total three hits in three different opinions. That is why these numbers shall not be overestimated. and 16 respectively (see Table 4.3). In terms of philosophers, John Rawls accounts for most hits (10 128 ), followed by Hugo Grotius (7), Thomas Hobbes and Hans Jonas with 5 each, Hannah Arendt (4), Jeremy Waldron, Jeremy Bentham, John Stuart Mill, Peter Singer, Michel Foucault and Aristotle with 3 each, John Locke with 2, as well as Immanuel Kant and Jean-Jacques Rousseau with one each, to name but a few. 129 Overall, 130 the qualitative content analysis (QCA) revealed that thinkers in a deontological tradition of thought dominate the reasoning in the EGE (see Table 4.3). 131 In its opinion (No 24) on 'ethics of modern developments in agriculture technologies', the EGE referred to justice, as the "institutional dimension of ethics". 132 When broaching issues of global as well as intergenerational justice, the EGE referred to Harvard philosopher John Rawls (1921Rawls ( -2002 133 and his 'original position', where everyone decides questions of justice from behind a 'veil of ignorance; hence, one would adopt "a 'maximin' strategy which would maximise the position of the least well-off". 134 For the global justice discourse, the EGE refers to this question of distributive justice, which deals with the question of which goods a society or a collective group shall distribute among its individual members. This geographical dimension addresses similar questions as along the timeline (i.e. 'justice between generations'), where "future or past generations can be viewed as holding legitimate claims or rights against present generations, who in turn bear correlative duties to future or past generations". 135 It is worth mentioning that this involves not only the perspective of rights, but also of duties, similar to the discussion on human rights and human rights obligations. 136 As we have seen earlier, conflict of interest is a key issue in ethics. Likewise, in this context, by again referring to Rawls, the EGE emphasizes that "if there is an intergenerational conflict of interests, considerations of justice could place an obligation on present generations not to pursue policies that create benefits for themselves but at the expense of those who will live in the future". 137 One year later (in 2009), the EGE picked up the same ideas of Rawls on justice in its opinion on 'synthetic biology '. 138 (2015) i While their classification to a normative theory is debated in literature and clearly challenging, Foucault and Arendt are covered here in 'virtue ethics, and related'. The author would like to thank Johan Brännmark for addressing the fact that Foucault is more about social theory than normative theory; the reason why he was addressed by the EGE in the field of surveillance might be that he is a relevant source because of his work on disciplining and governmentality Hans Jonas (1903, a philosopher focussing on relationship of man to nature and his handling of technology, has also highlighted this responsibility towards future generations. Based on Kant's 'categorical imperative', 139 in his 1979 book "Das Prinzip Verantwortung", he developed an 'ecological imperative', which states as follows: "Act so that the effects of your action are compatible with the permanence of real human life on earth". 140 The development of this deontological concept has to be seen against the historical background, where he saw the need to develop a new concept of ethics, since in the past technology did not have such ranges of action in space and time. In opinion No 27 on energy, the EGE has referred to Jonas, stating that his approach "is echoed in part in the implementation of the 'precautionary principle' in the legal EU framework, which reverses the burden of proof-the argument for the greater overall benefit of an action-in cases of expected harms or risk of envisioned technologies". 141 Likewise, the EGE links Jonas' ideas of obligations towards future generations to the 'principle of sustainability' with respect to the impact of present actions on future generations. 142 In this regard, the EGE refers to the values of human dignity (and human rights), justice (including distributive, social, political, and intergenerational justice), as well as solidarity (the shared responsibility and concern for EU and global welfare). These overarching rights and values shall "guide the development of an ethics framework oriented at a responsible design of the EU energy policy". 143 The aforementioned value of human dignity is another deontological concept, which the EGE in its opinion on 'synthetic biology' sees as "the core of the ethics framework for synthetic biology". 144 Although the EGE only refers to it as "[o]ne such attempt" to define human dignity, it quotes the following definition of medical expert William P. Cheshire 145 : The exalted moral status which every being of human origin uniquely possesses. Human dignity is a given reality, intrinsic to human substance, and not contingent upon any functional capacities which vary in degree.
[…] The possession of human dignity carries certain immutable moral obligations. These include, concerning the treatment of all other human beings, the duty to preserve life, liberty, and the security of persons, and concerning animals and nature, responsibilities of stewardship. This deontological concept of the 'intrinsic value' comprises, according to the "Kantian understanding of human dignity [which] emphasises moral responsibility", a prohibition of "treating human beings as mere 'objects' of the interests of others". 146 According to the EGE, this is especially important in case of vulnera-ble human beings, 147 referring to an idea addressed by Beyleveld & Brownsword in their seminal work 'Human Dignity in Bioethics and Biolaw'. Based on "the notion of dignity as a virtue", the idea of responsible behaviour, according to them, should be taken seriously; in that regard, the responsibility that underlies the notion of dignity, is a "responsibility that goes to questions of character as much as to the appearance". 148 Then they continue with the part that was (partially) quoted by the EGE 149 : "Specifically, it is the idea of dignity as a particular practical attitude to be cultivated in the face of human finitude and vulnerability (and, concomitantly, the natural and social adversity that characterizes the human condition)". 150 Hence, for the EGE, dignity "is the basis for more specific principles, rights and obligations, and is closely connected to the principle of justice and solidarity". 151 This corresponds to human dignity enshrined in Art 1 CFR and Art 2 TEU (EU's common values), as well as the above-mentioned emphasis not only on rights, but also on obligations.
With regard to patentability of biotechnological inventions, the EGE addresses the danger of commercial exploitation ('commodification'), which can offend human dignity, thus proposing three types of categories of inventions. First, that "which is common to all humankind, and should not be patentable or directly exploited for commercial gain", second, that "which, for a variety of reasons, should be placed in the public domain for all to use and exploit (the 'commons')", and finally, inventions that can be protected "at the inventor's discretion". 152 In summary, it can be said that based on the EGE's emphasis on human dignity, deontology plays an important role in bioethics. 153 Also in the field of 'security and surveillance technologies', the EGE emphasized that human dignity "is at the heart of ethics and is also of crucial importance regarding the debate" in this field. 154 Against the background of debates of increasing security by limiting freedom, the EGE makes a clear statement: "Human dignity is the core principle of the European moral framework, and as such it cannot be 'traded off'". 155 However, according to the EGE, "dignity is intimately associated with freedom and responsibility", and here a balance needs to be struck between those two. 156 In this context, the EGE draws on Jeremy Waldron (1953-), a New Zealand professor of law and philosophy, who uses the respect for the dignity of citizens as an argument 147 See Footnote 146. 148 Beyleveld and Brownsword (2001, p. 2 Pirs (2017, pp. 57-59). 153 Cf. also Pirs (2017, p. 56) with further details. for a moral entitlement to "transparency or the reasons why [the citizens] should apply certain laws". 157 This relationship of citizens and the state (rulers and the ruled) is also broadly addressed in terms of 'social contract theories '. 158,159 Starting from famous philosophers such as Thomas Hobbes (1588-1679 and the like, 160 the EGE reflects on security and "the moral justification of the absolute power of the state and of the citizens' limitation of freedom", 161 based on Hobbes' 1651 book 'Leviathan'. 162 While theoretically the elected representatives are bound by the 'people's will' (and can be held accountable), "this has turned out to be a challenge under the new security policies". 163 Pirs argues that in this field of security and surveillance technologies, the EGE applies "a more subtle approach towards a deontological understanding of human dignity", where rights are balanced based on the principles of proportionality and effectiveness. 164 According to the above-mentioned qualitative content analysis, there were clearly fewer references in EGE opinions to consequentialism (see Table 4.3). 165 This normative theory plays a role when assessing the consequences that arise from developments in the field of science and new technologies, i.e. the EGE's turf. In the context of risk assessment, these consequences relate to possible benefits versus possible risks. Anthropocentric approaches, placing humans in the centre of the universe, focus "on consequential considerations and issues related to potential consequences from the use of synthetic biology for human beings (risk assessment and management and hazard considerations […])". 166 The analysis of risk comprises the three elements of risk assessment, risk management and risk communication, where the already mentioned precautionary principle 167 is particularly relevant for risk management. 168 Such risk assessment is emphasized by the EGE "in order to protect 157 EGE opinion No 28,p. 78. 158 The EGE provides the following definition: "social (or political) contract arguments classically posit that individuals have consented, either explicitly or tacitly, to surrender some of their freedoms and submit to the authority of the sovereign (or to the decision of a majority) in exchange for protection of their remaining rights". These theories can be distinguished between some that are concerned with the origin of the state, while others focus on "the contract-the modus vivendi-between the ruler(s) and the ruled"; EGE opinion No 28, p. 62. 159 Pirs (2017, p. 60). 165 The author would like to thank Göran Hermerén for addressing the fact that, where a consequentialist approach was (also) called for, the EGE often discussed proportionality; on the latter, see Hermerén (2012). 166  human dignity and the autonomy of persons", in a similar way as the importance of the precautionary principle. 169 Hence, linking this consequentialist approach to human dignity, as mentioned above in the context of deontology.
Moreover, a consequentialist approach is applied by the EGE in the context of 'animal cloning for food supply'. Here, the EGE takes a more bio-centric attitude, 170 comprising ethical concerns for the cloned animals, for humans, for the environment, as well as for society. 171 Jeremy Bentham (1748-1832) is considered as the founder of modern utilitarianism, the most prominent form of consequentialism. As already mentioned, utilitarianism is egalitarian (as the well-being of each person is of equal value), and even the feelings of animals can be taken into account. 172 That is why Bentham is often regarded as one of the earliest proponents of animal rights. The EGE refers to Bentham, John Stuart Mill (1806-1876) and Peter Singer (1946, etc., in order to argue 'the moral status of animals', as "actions causing pain in sentient animals are morally unacceptable, since animals are considered moral subjects". 173 At the same time, the EGE also refers to a deontological line of argumentation, based on the 'intrinsic value argument', referring especially to literature focusing on animals' intrinsic value 174 and integrity. 175 In summary, the EGE concludes that it "has doubts as to whether cloning for food is justified", and "does not see convincing arguments to justify the production of food from clones and their offspring". 176 Accounting for slightly more hints than consequentialism (i.e. 10), the research of Pirs identified 12 references in EGE opinions to [3.] virtue ethics (see Table 4.3), which has been defined as "[a]n approach to both understanding and living the good life that is based on virtue". 177 What does this concept of 'human flourishing' imply for today's potential dangers arising from the corroding of privacy due to the introduction of new ICT tools? This 'good life' is addressed in the opinion on ethics of ICT in the sense that "giving up privacy would determine the flourishing of a personal and social virtue […] based on people's freedom to introduce and share whatever data on their own lives they desire". 178 In the end, the EGE calls for building "a stronger and more coherent data protection framework". 179 In this context, the EGE also refers to Hannah Arendt (1906Arendt ( -1975, one of the most important philosophers of the 20th century, as "one of the first scholars to observe the political importance of privacy". The EGE states that "Arendt's defence of the importance of the private sphere warns about dangers arising from the erosion of the private, a situation which some consider as deriving from the use of ICT as communication tools". 180 Also in the context of new health technologies and citizen participation, the EGE refers to Arendt 181 when addressing the danger of "downgrading of individual rights in pursuit of the collective good". 182 A famous representative of virtue ethics, Aristotle (384-322 B.C.), is mentioned in the context of ethics in ICT, where the EGE reflects on his "friendship as mutual care between equals" against the background of the "ethically important change" in the way in which social networks shape the concept of friendship and community. 183 Hence, we can see various examples of old concepts being applied to current as well as future challenges. However, despite these examples, it is important to emphasize that the EGE "does not clearly stipulate any normative ethical guidance on the basis of virtue ethics in this regar[d]". 184 One exception can be found in 'security and surveillance technologies'. There, the EGE refers to 'virtuous behaviour' in the context of the tension between privacy and new technologies, which has been addressed with regard to four instruments: technology, education, self-regulation and the law; in terms of the third one, according to the EGE, "[s]elf-regulatory governance works to promote (virtuous) behaviour by involving stakeholders and establishing bottom-up soft regulations". 185 As mentioned above, based on the first formal mandate (in 2005), since 2008 (i.e. Opinion No 23) the EGE has started to refer to normative theories, especially via their proponents. In this regard, it is fascinating to see a similar development in the legal sphere. As of Opinion No 16 (patenting of human stem cells inventions, May 2002), which falls in the 2nd mandate, 186 the EGE has also increasingly (9 hits) started to refer to EU and international documents, mainly in the field of human rights (see Fig. 4 Arendt et al. (2018). 181 Arendt (1951). 182 EGE opinion No 29, p. 41. In this context, the EGE also refers to Michel Foucault (1926-1984p. 40. 183 EGE opinion No 26, p. 42;Aristotle was also mentioned in EGE opinion No 25, p. 11, and EGE opinion No 28, p. 64. 184 Pirs (2017, p. 63). 185 EGE opinion No 28, p. 59. 186 2000-2005 here, the EGE became part of BEPA. No 30, see Pirs and Frischhut (2019, forthcoming)  Overall, we can observe an extension not only in pages, in references to normative theories as well as to these EU and international documents, but also in scope, as the group has moved from purely bioethics also to broader principles of human rights, as well as an increase in group members. There has also been an increase of the duration of the mandates, except for the last one. 190 As we know from the job of the president of the European Council, newly created by the Lisbon Treaty, 191 an appointment for two times 2.5 years allows for more control, compared to an appointment for five years. Apart from the normative theories covered in this chapter and based on the terminological delimitation, 192 the EGE has referred to values (human dignity, justice, freedom, solidarity, etc.), to human rights, as well as to principles (privacy, informed consent, non-discrimination, equity, precaution, sustainability, etc.).

Conclusion
It is evident, that both in EU legal documents (Sect. 4.1) as well as in case of the EGE (Sect. 4.2), ethics enters the scene in sensitive areas. This was the case with CETA (investment protection and the fear that big companies can 'buy justice'), as well as the Korea agreement (inappropriate influence of the pharma industry). In addition we can name the saving of Islandic banks in the context of EFTA (taxpayers' money and moral hazard), scepticism with regard to (regulation of) the financial world in general (cf. ethics committees in the field of ECB and EIB), and lobbying (the fear that big companies can 'buy law'), to name but a few. In case of the EGE, one reason for its establishment was also to address public concern on the new challenges raised by new (bio-)technologies. 193 In the following, the questions mentioned at the beginning 194 will be answered in more detail, as the results of Sect. 4.2 on the EGE will supplement those of Sect. 4.1.
With regard to the possible identification of normative theories (i.e. question No 1), we have seen implicit references in EU legal documents, implicit as well as explicit ones in EGE opinions. The latter have mainly referred to several proponents of 187 Dating from 11.11.1997. 188 Source: Pirs (2017, A37); mentioning twelve other documents in descending order. 189  these normative theories, but have also explicitly addressed these normative theories. Implicit references in EGE opinions especially addressed deontological ideas via the EU value of human dignity.
Question No 2 can clearly be answered in terms of addressing several normative theories, although these three theories are not equally represented. In EGE opinions, deontology clearly prevails, and we find less examples of virtue ethics. 195 However, it is important to emphasize that often the EGE refers to one normative theory, by emphasizing the consequences if the decision-makers opt for this theory, besides pointing to another normative theory, also emphasizing the consequences for this other theory. Hence, while there are most references to deontology, this disclaimer has to be kept in mind.
It was also remarkable to see justice as the "institutional dimension of ethics". 196 Justice occurred both in terms of distributive justice (Rawls), as well as with regard to future generations (Jonas). Human dignity, in Waldron's interpretation, also has an institutional component, in terms of citizens' entitlement to transparency in the decision-making process.
In both EU legal documents, as well as in EGE opinions, human dignity plays a paramount role. It was addressed to be at the 'core' of synthetic biology, at the 'heart' of ethics in the field of security and surveillance technologies, and was even addressed as the "core principle of the European moral framework". 197 This EU value clearly has a deontological connotation, when referring to the intrinsic value of humans, with similar ideas expressed with regard to animals. Throughout EU law, human dignity has been an argument against 'commodification' of the human body, based on the Kantian idea of not treating humans as mere objects. For the same reason, it has been emphasized that there can be no trade-offs. 198 Human dignity has been emphasized especially in case of vulnerable groups, which also links it to solidarity. This 'core principle', in more correct terms one would have to speak of 'core value', is the basis for further rights, principles and obligations, as we can also observe it in the CFR. 199 Consequentialism has been addressed by the EGE in the context of risk assessment. Apart from ethics, in EU law in general we have seen that impact assessment plays an important role in EU decision-making, as well as the 'effet utile' principle in CJEU case-law, both of which also have a consequentialist connotation. Utilitarian philosophers have been addressed when taking a more bio-centric approach, in particular with regard to animals. It is worth mentioning that the EGE both in case of risk assessment and with regard to animals has also taken a deontological approach, as it has emphasized the importance to protect human dignity and the autonomy of persons (in case of risk assessment), and has also referred to the intrinsic value of animals, as mentioned above.
Social contract theories have been addressed in terms of security and surveillance technologies. Although drafted during the age of enlightenment to legitimate the authority of the state, this concept is still of relevance and was applied to these new challenges.
Both for EU legal documents, as well as for the EGE opinions, all the examples we have seen cannot be understood as unconditional references to one or more normative theory(ies), but only as pointing towards them (question No 3). The EGE often refers to several views, for instance to deontology and to consequentialism, 200 without explicitly favouring the one, or rejecting the other view. In other words, in case of explicit references to normative theories, the EGE contrasts different philosophical views; hence, it is not possible to assign the EGE exclusively to one of these three normative theories.
Another question was, whether we can identify a certain common horizontal (or rather a specific) pattern, when referring to these terms of ethics and morality in EU legal documents (Sect. 4.1), respectively when addressing these normative theories (Sect. 4.2). As we have seen above with regard to EU legal documents, there is clearly no horizontal, but a specific approach in addressing different normative theories in different fields. Deontology plays a role in order to refer to general principles of morality, consequentialism to address effects of the ethical challenge at hand, and virtue ethics is addressed in the context of 'pursuing a good life'. 201 Against the background of the diverse topics of the 30 opinions so far, the EU's values with their corner stone of human dignity, a deontological concept, can be seen as the most horizontal approach in this regard.
Having now analysed the different 'layers' (in the sense of the hierarchy) and the different 'areas' (in the sense of the 'separation of powers') of EU law, the final question (i.e. objective 4), as to whether we can identify an ethical spirit of EU law, can be answered as follows. As stated above, in this book, the notion of spirit is understood as "the intention of the authors of a legal system, which is reflected in a lattice of various different provisions". In Sect. 4.1 with regard to EU legal documents, we have already identified both an ethical spirit, as well as a gap that still needs to be filled. The findings of Sect. 4.2 point in a similar direction, further emphasizing the predominant role of the EU's common values and the corner stone of human dignity. Apart from explicitly referring to these concepts from a legal angle as the values enshrined in Art 2 TEU, the deontological normative arguments addressed in the EGE's opinions also point in the same direction, hence further closing the gap addressed earlier. Having identified this 'lattice' of ethics in the different layers and areas, both binding legal provisions and soft-law, including the EGE's opinion, this does not mean that we have reached a final position. This analysis is valid as of 2018, might however be different in the future, and was clearly less elaborated in the past.
One example in this regard is Opinion No 12, on ethical aspects of research involving the use of human embryo in the context of the fifth framework programme, from November 1998. The EGE appropriately states that the EU has no proper competence in medicine, hence such protection falls within national competence. Nonetheless (i.e. first limitation), EU authorities "should be concerned with ethical questions resulting from medical practice or research dealing with early human development". 202 However, (limitation to the first limitation), in doing so, EU authorities have to take into account "the moral and philosophical differences, reflected by the extreme diversity of legal rules applicable to human embryo research", as "because of lack of consensus, it would be inappropriate to impose one exclusive moral code". 203 The question remains, if this diversity stipulated in 1998 with regard to embryo-related questions is still valid today, having in mind the growing importance of EU values, especially since 2009. To sum up, this ethical spirit is in statu nascendi, as we can also see from the 'united in diversity' approach we have seen in case of EU primary law.
Addressing these elements of constant development on a time line, it is worth mentioning that also the status quo, as viewed from today, has addressed retrospective elements (the historical responsibility for climate change and the moral obligation to assist ACP countries), 204 as well as the obligations with regard to future generations (nanosciences, Hans Jonas, etc.).
The ethical spirit of EU law identified in this book is subject to the following limitation. It only applies to EU law. Hence, this does not cover all the examples where reference is made to the national or local level (e.g. "compliance with local codes of ethics" 205 ). In those situations, the ethical spirit of EU law can only have an indirect influence, especially via the EU's common values. This is similar to 'morality' being determined by the different MS, but constrained by the EU's proportionality principle (especially the requirement of 'coherence'), as well as the prohibition of double morality, etc., as stated in the CJEU's case-law.
One final word about the just addressed difference in terminology, i.e. ethics versus morality. The reason why this book has not coined the term of the 'moral spirit of EU law' is primarily due to the reason that the notion of 'public morality' has essentially been used as a protection shield, in EU primary law (called 'reason of justification'), in international agreements (called 'exception clause'), as well as in EU secondary law. 206 Besides this, 'public morality' is a legal term while ethics is a term of practical philosophy. In terms of morality, 'public morality' is a collective term, while we have also seen a lot of variations of morality: 'moral support', 207 'moral condemnation', 208 'moral development', 209 a 'high moral standing', 210 'moral safety', 211 'moral responsibility', 212 as well as the economic term of 'moral hazard'. 213 The notion of 'ethics', 214 on the other hand, has not been used in such a collective way. 215 It has the advantages of not being a legal term (although used in legal texts) and it has not been used as a 'protection shield'. 216 Now that we have examined the 'ethical spirit of EU law' from a philosophical point of view, we turn to the legal perspective.
