Constitutional Writings of Pierre-Louis Rœderer
|
Pierre-Louis Rœderer,
Écrits constitutionnels, introduction et édition critique de Julien Jeanneney, Dalloz, coll. Bibliothèque Dalloz, 2022, xxxii + 375 p. 
|
Introduction and critical edition of ten texts on constitutional law by Pierre-Louis Rœderer - including one unpublished text found in the French National Archives. A jurist and a major member of Napoleon's first Council of State, Rœderer played an important role during the Revolution and the Empire. Between 1788 and 1835, he expressed his constitutional thinking in a number of notes, articles and pamphlets. The interest of these texts stems both from their theoretical scope and from what they reveal: a singular narration of the events of the Revolution, placed in the service of an institutional project. Through them, Rœderer contributes to forging a collective understanding of a political modernity then under construction. Beyond an apparently descriptive project of the revolutionary events, his work conceals a prescriptive ambition, with two main dimensions: the consolidation of a sovereign political community which requires, according to him, a representative form of government.

Constitutional Gaps
|
This research started from the claim, made by Hans Kelsen and many other scholars, that gaps are impossible in legal systems in general and particularly in constitutional systems. The book shows that despite the diversity of books and articles striving to prove the impossibility of gaps, in several countries, since the end of the 19th Century, the very idea of gap remains largely vague when used by legal scholars. Hence, it was important to confront the many concepts put behind the word "gap" and positive legal systems, and especially the French 1958 Constitution – the goal of this confrontation being to shed some light on the relative values of each of those concepts.
The first part of the book is based on a "descending" reasoning: starting from the usual claims in legal theory regarding legal gaps, and arriving to positive law, the book shows that constitutional gaps are based on some legal dogmas. Firstly, constitutional gaps are hard to know. One is always prevented by some systemic and linguistic impediments to fully know the gaps. The former impediments proceed from a dogmatic imaginary that surrounds the systemic vision of legal norms. The later impediments prove to be the consequence of indeterminacy in legal communication. Secondly, constitutional gaps are hard to deny. The books shows how limited are the usual claims made in order to prove the necessary completeness of legal systems, when confronted with positive law: first, the arguments based on the idea of an implicit subsidiary norm, ponctual or general, supposed to guarantee the completeness of a system which seems to have a gap; then, the arguments based on the idea of the irrelevance of legal gaps, since the enforcement of legal systems always enable the judge to fill such gaps.
The second part is based on an "ascending" reasoning: starting from positive law, and arriving to claims in legal theory regarding legal gaps, the book shows the actual effects of the argumentative use of the idea of gaps by several interprets of the law in general, and of the French 1958 Constitution in particular. Firstly, constitutional gaps are phenomena presented as something that one can simply discover in the law. As such, gaps are an imperfect measuring tool. Such imperfection derives from the tendency of legal scholars to call "gaps" the consequence of the confrontation of the law as it is, and of the law as it ought to be, or to call "gaps" the technical situation in which the lack of a legal norm deprives a superior norm of legal efficiency. The books claims that a new concept of gaps – called "institutional gaps" – is useful to designate situations in which the lack of a constitutional norm can be deemed more objective than others. Secondly, in a strategic perspective, legal gaps tailored by the interpret that claims that they exist appear a subversive legal tool. Axiological gaps are a model of legal argumentation, used by public authorities or by constitutional judges in order to circumvent constitutional provisions. The book shows how efficient such a tool can be.

The Master of Vaccines.
Brazil's Supreme Federal Court in the Thick of the Fray "Le maître des vaccins.
Le Tribunal fédéral suprême brésilien au cœur de la mêlée" Revue française de droit administratif, vol. 38, n°3, 2022, p. 576-586 |
The covid-19 pandemic has not only severely affected the Brazilian population, but has also created tensions between institutions, both horizontally - between the organs of the Federal Union - and vertically - between the federal executive and the federated entities. The role played by the Supreme Federal Court during this period was peculiar: through various decisions - most notably, in December 2020, on the determination of the authorities entitled to prescribe compulsory vaccination - it contributed to the transfer of the health powers of the President of the Republic and of the Minister of Health of the Union to the federative entities, in circumstances that are worthy of renewing the long-standing debate on the political role of constitutional courts and on the ways in which constitutional justice decisions are motivated.

Citizenship and
Compliance With the Law "Être citoyen, obéir aux lois"
Jus Politicum, vol. 27, 2022, p. 143-171 |
Although it is usually seen through the lens of political rights – right to vote, right to be elected – citizenship also implies duties, especially a duty to obey the law. This correlation between obligation to comply with the law and citizenship deserves to be further clarified and tested. We argue that two concepts of citizenship, which are often blended together, citizenship in a philosophical sense and citizenship in a legal sense, should be differentiated ; that the obligation to obey the law is a necessary feature of citizenship in a philosophical sense, not of the citizenship in a legal sense

Calhoun's Revenge:
Abortion as a Challenge to American Federalism "La revanche de Calhoun:
l'interruption volontaire de grossesse au défi du fédéralisme américain" Revue française de droit administratif, vol. 37, n°6, 2021, p. 1199-1128 |
Particular attention should be paid to the emergency order by which the Supreme Court refused to suspend the application, before its entry into force, of a law of the State of Texas substantially reducing the period of time during which women can obtain abortion care. It sheds light on an original legislative mechanism: by entrusting private persons with the task of guaranteeing its enforcement before civil courts, Texas develops a legislative shell intended to immunize itself against constitutional review. This raises a thorny challenge for American federalism.

The Reappearance of Punitive Closures of Places of Worship
"La résurgence des fermetures punitives
de lieux de culte" Revue française de droit administratif, vol. 37, n°3, 2021, p. 519-533 |
In France, punitive closures of places of worship have been abandoned, for the most part, since the French Revolution. They reappeared half a decade ago, by the combined action of the Parliament, of the Government and of the administrative judge. The closure of the Pantin mosque, in reaction to the murder of Samuel Paty – a middle-school teacher, killed and beheaded by an Islamist on October 2020, after a course he taught on freedom of expression – gave visibility to such a policy. This paper shows that such closures, ordered for punitive purposes, upsets, in a perilous way, the subtle balance institutional guarantees of freedoms, and the collective aspirations for public safety.

Putting the French Revolution in Order. About Pierre Louis Rœderer’s Constitutional Ideas
"La Révolution mise en ordre. Sur la pensée constitutionnelle de Rœderer",
Jus Politicum, vol. 24, 2020, p. 273-303 |
Pierre-Louis Rœderer was an important actor of the French Revolution and the First Empire. He was active from the Ancien Régime until the July Monarchy. He published a great number of constitutional writings, which deserve to be exhumed. This article shows that they reveal an ambition to put the French Revolution in order. First, in an intellectual manner: he makes an essential distinction between the liberal inventiveness of 1789 and the violence of 1793.Then, in a more concrete way: the concept of "public order" takes a central place in his political theory.

The Non-Theory of “Special Circumstances”.
About the Decision Regarding the “State of Health Emergency” Organic Legislation "La non-théorie
des circonstances particulières. Sur la décision relative à la loi organique d'urgence sanitaire" Actualité juridique droit administratif, vol. 76, n°15, 2020, p. 843-848 |
In reviewing an organic law adopted in disregard of a procedural constraint imposed by the Constitution, the Constitutional Council declared it to be in conformity with the Constitution. The interest of its decision lies in its contra constitutionem scope, in the motive that seems to underlie it – the diffuse feeling of a state of necessity – and in its lapidary motivation, symptomatic of a singular way of administering constitutional justice in France.

Disobedience
"Désobéir",
Droit & Littérature, vol. 3, 2019, p. 97-109 |
From a legal standpoint, disobedience is ambivalent. It represents a risk for the law: the rejected rule is less effective and less stable, and the sanction attached to its violation loses its dissuasive impact. It also proves to be a resource for the law: prompted by legal norms, this act can lead to the revolution of the normative system altogether.

Scandal and Fury. About Brett Kavanaugh's confirmation to the Supreme Court
"Le scandale et la fureur.
Sur la confirmation de Brett Kavanaugh à la Cour Suprême", Jus Politicum, vol. 22, 2018 |
Brett Kavanaugh's confirmation hearings leave unanswered an allegation of sexual misconduct and the possibility of a perjury in front of the United States Senate Committee on the judiciary. The article shows that those hearings were not as original as we could think: they fit into a long tradition of scandals that showed up during confirmation processes such as this one, and that shared with this one many common points. What was original, here, was the nominee's defense strategy: Brett Kavanaugh broke with the a tradition of usual behavior of Supreme Court nominees who try to remain calm and to embody the abstract idea of judicial dignity.

Presidential Dignity in the Criminal Court: the Trial of Jacques Chirac
"La dignité présidentielle devant le tribunal correctionnel: le procès de Jacques Chirac", Revue du droit public et de la science politique en France et à l'étranger, vol. 134, n°2, 2018, p. 407-422
|
More than five years after former French president Jacques Chirac's trial, it is possible to shed a new light on the constitutional provisions regarding the French president of the Republic, beyond their temporal scope, and on the conditions pursuant to which first level politicians can be judged by a ordinary criminal court. Jacques Chirac's trial put an end to the commonly shared idea of the criminal impeccability of the French head of state. This article shows that two common claims in French constitutional law should be nuanced i.e., that a former president would become, after the term of his presidency, an "ordinary" citizen to be held accountable by the law as any other citizen, and that the criminal judge would be in a better position to judge such a politician than the political judge.

Legislative Intent and Normative Ambiguity
"Le recours à l'intention du législateur face aux énoncés normatifs ambigus", Droit & Philosophie, vol. 9, 2018, p. 79-119
|
It is commonly believed that legislative intent is a way to eradicate the ambiguity of a legal norm. This articles highlights the many confusions surrounding the concept of "legislative intent", and offers a clarification of the phenomena referred to by such an expression. It shows that references to legislative intent are flawed, in several ways, and that many of the claims made about such a use of legislative intent are to be criticized.

Misappropriation of Land Reserves for Commercial Purposes
"Le détournement des réserves foncières à des fins mercantiles", Revue française de droit administratif, vol. 31, n°5, 2015, p. 937-955
|
For a long time, land reserves have been seen as a way to control the price of the land in France. Many of them are misappropriated by local authorities: by way of example, lands that have been expropriated or pre-empted in the past are then sold by the authorities, retrospectively depriving the land reserves of their purpose. The article claims that administrative interest and general interest should be differentiated in that instance.

Atlantis. Submersion of the State in International Law
"L'Atlantide. Remarques sur la submersion de l'intégralité du territoire d'un Etat", Revue générale de droit international public, vol. 118, n°1, 2014, p. 95-130
|
The prospect of a rise in sea levels bringing about the total submersion of some island states’ territory raises new questions for international law, questions that should be considered in anticipation of this geophysical phenomenon. The physical disappearance of a State’s territory would be a new cause of State extinction, and all the more original as it would, by assumption, make the succession of States impossible. Notions which form the cornerstone of international law – the territory and the State – will potentially need to evolve when faced with a geophysical phenomenon of such magnitude.

Case Law Outside the Courtrooms
"La jurisprudence hors des prétoires, source négligée du droit constitutionnel",
in A. Le Divellec (ed.), Des institutions et des normes, Éditions Panthéon-Assas] To be published, Fall 2022 |
Could it be that the jurisprudential phenomenon extends beyond the courtrooms, where our legal culture has become accustomed to confining it? Various practices of executive bodies or of the Parliament share many common features with the "case law of the courts". Very often, they are reduced to concepts that are not tailored to them - first and foremost constitutional customs or conventions. We try to shed light on this neglected source of constitutional law.

Legal Uncertainty.
An Argument in Parliament "Insécurité juridique. Un argument au Parlement", in G. Cerqueira, H. Fulchiron, N. Nord (ed.), L'insécurité juridique: L'émergence d'une notion?, Société de législation comparée
To be published, Fall 2022 |
As a phenomenon, legal uncertainty is not new. As a legal category, it is as rare as it is recent. As a concept, it suffers from defects similar to that of "legal security", which has been singularly popular since the early 1990s. As an argumentative resource, it is commonly invoked, in plenary sessions, in the French National Assembly. Its interest lies less in what it designates - a set of phenomena already apprehended by other concepts - than in what its increasing invocation reveals about our societies and our contemporary legal systems.

Is the Constitution, in Canada, a Canadian One? About the 1982 "Patriation"
"La Constitution, au Canada, est-elle canadienne? Remarques sur le "rapatriement" de 1982", Révolution, Constitution, Décentralisation. Mélanges en l'honneur de Michel Verpeaux, Dalloz, 2020, p. 347-360
|
Although largely in control of its own internal and external destiny, Canada has long been unable to amend, without an act of the British Parliament, a Constitution that the British Parliament had adopted for it and had not ratified. The attribution to Canada of the power to directly amend its Constitution - presented as the "Patriation" of the latter - is less a normative revolution than a symbolic and political rupture. This original form of constitutional spatial change within the Commonwealth nonetheless raises several challenging questions for constitutional theory.

Constitutional Complaints
"La réclamation en droit constitutionnel", in D. Rousseau (dir), Réclamer en démocratie, Mare & Martin, 2019, p. 51-117
|
Registers of grievances before the French Revolution, petitions, street demonstrations, requests and appeals, conversations with members of Parliament: all of the above are part of the idea of "constitutional complaints", even if it is not always easy to distinguish precisely what comes under it and what does not. However, the community of properties attached to these phenomena and the questions they bring forward regarding the theories of sovereignty and representation justify that they be studied together. To this end, we develop a concept of "constitutional complaints", and then we apply it to constitutional law.

Constitutional Reformism during the French Fifth Republic
"Le réformisme constitutionnel sous la Ve République", in Ph. Blachèr (dir.), La Constitution de la Cinquième République: 60 ans d'application (1958-2018), LGDJ-Lextenso, 2018, p. 135-153
|
Constitutional reformism can be understood as the tendency to prescribe a change in the Constitution, in order to improve institutions and the protection of rights and freedoms. Embodied by the public statements that strive to convince that the Constitution should be amended, constitutional reformism sheds a new light on constitutional norms and constitutional interpretations. This chapter circumscribes the concept of "constitutional reformism" before putting into perspective some of the main manifestations of such a phenomenon.
