🚧 Conceiving Power

► Full reference: M.-A. Frison-Roche, Conceiving Power, Working Paper, December 2021 - 📝 This Working Paper serves as the basis for an article to be published in the collective book drawn up in tribute to Professor Emmanuel Gaillard.    - ► Working Paper summary: In 1985, Emmanuel Gaillard's central work came out under the title Le pouvoir en droit privé  (The Power in Private Law)📎1Gaillard, E., Le pouvoir en droit privé, préf. Cornu. G., coll. ..., Economica, 1985., but when it was defended in 1981, his thesis directed by Dean Cornu was entitled La notion de pouvoir en droit privé (The notion of Power in Private Law) 📎2Gaillard, E., La notion de pouvoir en droit privé, thèse .... ; . Let's give full force to the original title of the thesis.   The deletion of the term notion perhaps implies that by defining something the essential is done, that there would be something of a pleonasm in aiming at The notion of Power and The Power, as Law likes to economise on words.   But it was indeed a renewed, simpler and more powerful conception of the notion of Power, containing the entire regime necessarily imputed, that this work imposed, henceforth illuminating positive Law. Emmanuel Gaillard's definition, on the other hand, goes beyond Private Law. We would gladly have argued in favour of retaining the heading for the term Notion, proposing instead to dispense with the reference to Private Law alone …. Perhaps it was because the concept is so vast that in this seminal thesis its scope was restricted to Private Law, since the author already had to account for the sheer multiplicity of manifestations in this part of the legal system; Or perhaps it was because the concept of 'Power' is so familiar in Public Law that it would have needed less definition in Public Law (which, moreover, is so diversely proposed in this more political area, which is already careful on principle to distinguish between powers, which must always be plural in order to be separated), and that it was therefore reasonable to want to arrive at a single concept of Power in Private Law, where the notion of subjective rights is more familiar.  However, Emmanuel Gaillard's definition of Power as a prerogative placed, by legal rule or contract, in the hands of the person invested with them for the benefit, at least in part, of others, covers both Public and Private Law. This even contributes to the solidity of this thesis and explains why it flourishes today in legal systems where the distinction between Private Law and Public Law is weakening. The power of this definition lies in its simplicity. Simple and brave minds are often the most fruitful. As Dean Gérard Cornu points out in his preface, the author, in particular because he bases himself more on positive law, for example that relating to the powers of corporate officers, does not get bogged down in discussions between authors only to end up preferring one over the other. He arrives at a definition that is close to our everyday experience: the one we experience when we collect an envelope on behalf of someone else and the agent asks us in what capacity we claim to be doing this on his behalf. We then show him our 'power', the legal power to do so for the benefit of the person to whom the letter is addressed, and can thus exercise the power to withdraw the letter, even though it is personal. When legal and common sense come together, it is a good omen, not only in terms of form, because everyone can understand it and the Law must remain comprehensible, but also in terms of substance, because everyone must be able to control the exercise of a power that is exercised for and over others. For this letter addressed to someone else, the person who has been able to take it by virtue of the power conferred on him/her, could just as easily open it and read it, then destroy it or give it to the worst enemy of the person to whom it was addressed. In Power, there is always might to do, and the danger to others that Power contains therefore.  This highly legal definition of Power not only distances the holder from his/her own interests, but also channels the Power thus granted to the person who benefits from it. In this respect, Emmanuel Gaillard not only distinguished between Power and subjective right, but also identified the right amount of power required for this power to effectively fulfill this 'Mission', through the notion of abuse of power, when the holder uses for other beneficiaries this power that was conferred on him/her for this sole purpose. What is more, this concept makes it possible to distinguish Power from discretionary force, because the holder of Power thereby exercises factual , by acting for others, deciding for others, deciding on others. Because Power is inseparable from might, but might must remain the means of power and no more, the Law shall produce the antibodies that are not only the theory of abuse of power but also an Ex Ante responsibility that accounts must always be rendered, either to the other for whom everything is done or to a third party. For this third party is often there from the outset, the guardianship judge for example: because the Power was put in place because of the beneficiary's weakness, both in himself/herself and because of the situation, an impartial and disinterested third party is needed to ensure proper execution from the outset, without there even being a dispute. In this respect, how useful this thesis is for thinking about what Supervision is today!   This thesis, so clear, so simple and so strong, goes beyond Private or Civil Law. It is both much more restrictive than the more factual and political definition of Oower, which would be the ability to do something, and much broader than the usual definitions, since it embraces and legitimises de jure all situations where a person acts legally for the benefit of another.  Dean Cornu shows, moreover, in two sentences that such a notion of power also captures the office of the judge, who has power over others only to serve them 📎3"En droit processuel, l'office du juge aurait donné à l'auteur un renfort. Pour le juge, il n'est point de pouvoir sans devoir. Au-delà de la distinction de ce qu'il a obligation de faire ou faculté d'apprécier, il y a toujours, au creux de ce qu'il peut, le sceau de ce qu'il doit, un devoir gardien - comme un âme - de l'exercice du pouvoir." (p.5).. The definition corresponds to the mission of one who has power only to fulfill his office. It suits so well the conception we have today of Administration, especially if it takes the form of independent authorities. Moreover, Power thus contains its own limit in its very definition, since others are present in it: the holder has power only to serve others. From then on, it is only a power because it is a kind of Charge. Emmanuel Gaillard immediately uses the term: "Un individu se voit confier une charge qu'il exerce dans un intérêt au moins partiellement distinct du sien propre"  ("An individual is entrusted with an office which he exercises in an interest at least partially distinct from his own") 📎4n°3, p.9. . Dean Carbonnier, who reformed the legislation in this area 📎5🕴️J. Carbonnier, 📗Essai sur les lois, 1992 (on the guardianship).,, emphasised that the guardian has a public duty because the State entrusts him/her with a child. In the same way parental authority is a charge on the parents for the benefit of the children. More generally, Power is a burden that the Law places on a person to satisfy the interests of another. This definition offered by Emmanuel Gaillard in 1981, anchored in Private Law only insofar as it is the entire legal system, is premonitory of the Regulatory and Compliance Law as it unfolds today. It would be enough to continue the Gaillard's sentences, as if they had been half-written, to finish them 40 years later and find in them the mechanisms of Supervision of companies by public authorities which are now in place not to reduce their power but to ensure that they exercise it for the benefit of others 📎6S. in a general way, 🕴️M.-A. Frison-Roche (ed.), 📕Régulation, Supervision, Compliance, 2017.. The whole evolution of Company Law and Financial Law is here. Between the lines of this thesis, which develops the notion of duty 📎7Cornu, préface précitée : "Tous les pouvoirs sont, à double face, des pouvoirs-devoirs" (p.5)., we can also see what positive Law is developing today, in particular through the 'duty of Vigilance', this personal responsibility for the benefit of others (I). The definition of Power thus conceived contains within itself its regime and enables us to anticipate it better today: because the holder exercises Power only for others, at least partially, he is consubstantially accountable for it, responsibility being only one form of this accountability; because this service must be effective and others must benefit fully from it, because unlike the subjective right which allows the holder freely not to use his might, Power has never been the 'most absolute' availability to use his/her might: it is even the opposite. It is the expression of a Power assigned to a purpose, compelling the holder to use his/her Power to that end.  But it is equally necessary for the holder to have all the might to do so, otherwise the very notion of 'Power' is meaningless. This is the definition that should be given to the principle of Proportionality: the person on whom the Power rests must have not more power than is necessary, but all the power necessary to achieve the Monumental Goals for which the Power has been entrusted to him/her, so that others may derive full benefit from it (II).  In today's positive Law, the definition of Power as a Duty is found not only in Private Law but also in Public Law, not least because pure might, i.e. those that do not account for the use of their might, are in decline while concern for others is on the increase. The days of discretionary powers are over, and the increased independence of those who exercise Power over others requires them to be accountable. Beyond this Accountability, the personal Responsibility of those who have the Power to serve others is being established. But, no doubt because the Law is slow to evolve, the correlative idea that the holder of Power must have all the powers required to carry out his/her mission is less entrenched:  As Emmanuel Gaillard has shown, the Law has only gone part of the way in sanctioning excesses of power, when the holder uses his/her power for other goals, but it has not yet clearly established that the holder – sometimes forced – of a Power is legitimate in using all the means required to achieve the result for which this Power, i.e. a charge and a duty, has been conferred on him/her.   No doubt we need to read Emmanuel Gaillard's thesis again in all its potential, to imagine the reading we could do today of what he could have written as if on blank pages that would write themselves, a magical thesis where everything is already there, a thesis so short (250 pages) and so beautiful, so dense that it already contains the Law of the Future. The Law of the Future 📎8On Compliance Law as a Law of the Future, s. 🕴️M.-A. Frison-Roche, 📝Compliance Monumental Goals, beating heart of Compliance Law, in 🕴️M.-A. Frison-Roche (ed.), 📘Compliance Monumental Goals, 2023. On the consequences for Liability Law, which is now looking to the Future, s. 🕴️M.-A. Frison-Roche, 🚧Ex Ante Responsibility, 2021.  where there must be much more responsibility for the benefit of others📎9Sur la notion de "Responsabilité Ex Ante", v. Frison-Roche, M.-A., La responsabilité Ex Ante", in Archives de Philosophie du Droit, La responsabilité, 2022. and powers since this notion includes others who are the beneficiaries. Droit de l'Avenir where Emmanuel Gaillard will be present, in particular thanks to this work of doctrine offered in 1981.  So that, in practical terms, those who are entrusted with looking after others – for example, today all companies obliged by Compliance Law to look after others so that they are not destroyed by hatred in the digital space, by corruption in the economic system or by climate change in a projected future – do not find themselves challenged by the same Law for the means of exercising this power for the benefit of others, for example when this involves 'judging'. Dean Cornu himself emphasised the identity of the two offices. -                         Lire les développement ci-dessous⤵ - 🌐 follow Marie-Anne Frison-Roche on LinkedIn 🌐follow Marie-Anne Frison-Roche on Instagram 🌐subscribe to the Newsletter MAFR Regulation, Compliance, Law

📝Regulating Competition in Digital Platform Markets : A Critical Assessment of the Framework and Approach of the EU Digital Markets Act

► Full Reference: P. Akman, "Regulating Competition in Digital Platform Markets : A Critical Assessment of the Framework and Approach of the EU Digital Markets Act", (2022) 47 European Law Review 85, available at SSRN: https://ssrn.com/abstract=3978625 or http://dx.doi.org/10.2139/ssrn.3978625 - ► Summary of the article (made by the authors): "The European Union’s Digital Markets Act (DMA) initiative, which is set to introduce ex ante regulatory rules for “gatekeepers” in online platform markets, is one of the most important pieces of legislation to emanate from Brussels in recent decades. It not only has the potential to influence jurisdictions around the world in regulating digital markets, it also has the potential to change the business models of the wealthiest corporations on the planet and how they offer their products and services to their customers. Against that backdrop, this article provides an analysis of the aims of and principles underlying the DMA, the essential components of the DMA, and the core substantive framework, including the scope and structure of the main obligations and the implementation mechanisms envisaged by the DMA. Following this analysis, the article offers a critique of the central components of the DMA, such as its objectives, positioning in comparison to competition law rules, and substantive obligations. The article then provides recommendations and proposes ways in which the DMA – and other legislative initiatives around the world, which may take the DMA as an example – can be significantly improved by, inter alia, adopting a platform-driven substantive framework built upon self-executing, prescriptive obligations.". - 🦉This article is available in full text to those registered for Professor Marie-Anne Frison-Roche's courses -

🎤Legal Focus : Compliance Ex Ante, in 📅Toward Automated Compliance in the Data Economy

► Full Reference: Frison-Roche, M.-A., Legal Focus: Compliance Ex Ante, in GAIA-X, Toward Automated Compliance in the Data Economy , November 30,  2021, online -   Read the program. Listen to the intervention.   Intervention Summary: Compliance Law has two senses and GAIA-X is a perfect illustration. Firstly, to respect rules and show in Ex Ante permanently this respect (procedural definition) ; secondly, to pretend certain specific "Monumental Goals" (substantial definition). In this second sens, Compliance Law is very different from Competition Law: it required in Ex Ante collaboration, transparency, stability to reach these Monumental Goals around the respect and protection of Humans, while Competition Law is based on fighting,  mobility and trade without obligation Ex Ante, just sanction Ex Post if a prohibitive behavior occurs.  GAIA-X is based on Compliance Law, established for the purpose of a European Data Industry, a Monumental Goal linked to the Sovereignty and people's protection: it must structurally oblige its members to collabore for this goals, notably through its policy rules (first sens).  It is also a part and subject of the European Union Law. In the sense, its members must obey European Regulatory system (second sens). The both are narrowly linked because the European legal system has the same purpose of sovereignty, internalization of goals in enterprises and individuals' protection: GDPR, Cybersecurity, Digital Services Regulation, etc. : members must show permanently they do it actively. Because the purposes of GAIA-X and the purpose of the European Union Law are now the same in the Compliance Law the respect of letter's Law but also the respect of spirit's Law matters. Both are Ex Ante. Therefore, Compliance by design, which is also Ex Ante, is adequate.   Automated Compliance (and automated Certification) are tools to obey and reach the Monumental Goal. GDPR has specific dispositions (articles 24 and 42) about them, but more generally the efficiency these tools are validated by Regulatory Body, and Courts notably through the design of Smart Contrats.  It could be prudent to put in adition some human Compliance control because, by definition, an Automated Compliance is just the technological transposition (second level) of legal norme (first level) and cannot create new normes.  This is why the more important in this conception in Ex Ante of Compliance by this marriage between Law and Technology is to keep in mind not only the letters put in the algorithms but only the spirit of Compliance Law. -   Go back to the previous intervention about Compliance Law as an adequate branch of Law for GAIA-X (November 2020)

🎤The temporal dimension: imminence and intertemporally, in 📅Climate Change Cases before National and International Courts Cross-fertilization and Convergence”

► Full Reference: Frison-Roche, M.-A., Chair for "The temporal dimension: Imminence and Intertemporally", in Climate Change Cases before National and International Courts Cross-fertilization and Convergence", November 27, 2021, Paris.  -   read the program   Summary of the panel presentation: The specific topic of our panel is the “temporal dimension” of the judicial cases of Climate change. We shall listen to two great experts on this topic, which is Time. Listening the other previous speakers, I understand how this topic is important, because Climate Change requires an immediate action and it create a political issue, because everyone comes before courts. A basis and fundamental problem, because the times are not adjusted.  let's come back to basic notions, to have three times : “past, present, future”.   The issue of Climate Change is in the Future, the necessity of Action is in the Present and the basis temporal question is to know if Courts are the bodies adequate to responde ; maybe it is inevitable that Judge must be recreate their office because the time of the classical judicial office is the Past. Immediately, this simple et huge problem appears : in a classical repartition, the judge is the legal character to intervenir for the Past, the present (maybe is for you and me), and the future is the time for the State, and more precisely for the Parliament. But the climate change is a huge topic, not in the past, not in the present, but in the future. Therefore a gap exists between the time of the topic and the time of the court before the case is explained for obtaining a solution : how to give a good answer ? Judge maybe must travel in time, from past to future …. Maybe, he must, but might he? Classically, the judge can anticipate a very next future, but not the more distant and systemic future. Climate change belongs to the second one. This is why the title of this panel is non only about the necessity to take in consideration the “imminence” but also the “intertemporally” : maybe court are the sole able to create this intertemporality between Past and Future, and by this way to obtain from States and companies to do something immediately !   By two legal ways.    Courts can stay in Past, supervising States, if they dispose of effective legal decisions taken by States in the past about Climate Change (essentially Paris Agreement, for instance transposed in the French legal system by a formal law). This is why an efficient judicial solution would be the possibility for the courts to oblige State to implement their more or less committment they had taken in the past for the future (as the Conseil d’État did in the Commune de Grande-Synthe Cas Law). Even for that, the courts must adopt a creative notion of what is a commitment from a State through a Law… ; as they must do about private companies comitment (in their codes of conduct or soft law of corporate social responsability).    But what to do if States didn’t take such commitment ? Some can allege Courts are not Parliaments and are not legitimate to rule for the future … It is a political issue, a very classical one but very accurate for Climate change (where States and companies are face to courts…) and maybe  And as our colleague said, judicial system is quite technically weak to concretize human rights.   Therefore, the second way, more innovative, est the new use of Tort Law : no more a liability Ex Post, but a responsibility Ex Ante. In every legal system, even in Civil Law systems, Tort Law is conceived by courts (for instance in French Law).  If the new reasoning is conveived in Ex Ante, Tort Law must be a set of legal tools to reach the monumental tools to reach the "Monumental Goal" (being by nature future) which is the Climate Change stopping.  In this teleological reasoning, the admissibility and the choice remedies, must be adapted to obtain what is central : the effectivity and the efficiencicy.  In this sens, the judgement between two parties (which was an Ex Post act) may be conceived as an systemic efficient action (which was an Ex Ante act), because it must be.  -

From this new general conception, the Vigilance obligation, about which so much was said when it was imposed in France in 2017, is the advanced point, soon taken up in Europe and whose scope must be naturally global, because that Compliance Law is consubstantially global. Taking up more technically the legal techniques of Compliance and confronting them with the Competitiveness of firms, it is necessary that these Compliance Tools do not harm this Competitiveness because Compliance Law , supporting immense ambitions, can only function through an alliance between political  wills (with great pretensions, i.e. save the planet) and the entities which are able to concretize them (the crucial economic operators): the Compliance tools designed by legal systems must preserve the companies which put them in place and never favor their competitors. On the basis of this principle, it is possible to assess these two legal techniques,  namely the whistleblowing and the Vigilance duty,  which both capture Information, which, as such, gives them a uniqueness and places them in the global Competition for Information. Taking the whistleblowing first, it appears that its first beneficiary is the company itself since it discovers a weakness and can therefore remedy it. This is why, beyond the principle of protection of the whistleblower by the access of somebody to the legal statute conceived in France by the law known as "Sapin 2", it is criticized that all the incentives are not used for that the holder of such information transmits it to the manager and that the same law continues to require the absence of financial counterpart, the "heroic figure of the whistleblower and the refusal of his remuneration depriving the company of a means information and improvement. The American solution is better and tt is regrettable that the law transposing the European Directive maintains this ineffective conception. But French legislation has on the contrary developed the right incentive as to the person whom the information must be transmitted to is the manager, then externally if the latter does nothing. The solution is better that the American solution because the incentive is thus made to push the internal manager to act and put an remedy to the internal dysfunction, which increases the competitiveness of the company. Even more, even if it seems counter-intuitive, the French Vigilance Duty greatly increases the competitiveness of the companies which are subject to it. Indeed, the 2017 Law by obliging them to prevent and fight against  human rights and environment violations has tacitly given them all the necessary powers to do so, in particular the power to capture Information on third-party companies, including ( and even above all) those which are not subject to transparency obligations. In this, companies, insofar as they are personally responsible, hold a supervisory power over others, a power which allows Compliance Law to globalize and which, in the process, increases their own power. This is why the obligation of vigilance is in many respects a boon for the companies which are subject to it. The resumption of the mechanism by the next European Directive, itself indifferent to the territory, will only strengthen this global power on other firms, even foreign ones. - ► This  conférence et le document de travail servent de base à un article dans un ouvrage : 📝This conference and the Working Paper constitute the basis for an article:  📕  in its French version in the book  Les buts monumentaux de la Compliance, in the Series    Régulations & Compliance  📘  in its English version in the book Compliance Monumental Goals, in the Series    Compliance & Regulation -
