Graduate students and postdoctoral fellows

Lucien Carrier – doctoral candidate

Lucien Carrier
Lucien Carrier has a keen interest in constitutional theory, legal theory and philosophy of law. His readings have led him to taking into account both the historical and sociological dimensions of law, as well as its ties to political theory in general. Having studied in France, England, Scotland and now Québec, he greatly values the importance of identifying and discussing perspective in the study of law.

Project: Le recours aux classifications des formes politiques pour décoder l’ordre constitutionnel britannique : processus utile ou obstacle épistémologique ? (Classifications of Political Entities as a Means of Understanding British Constitutional Order: Useful Process or Epistemological Barrier?) (2019 – )

Representation of the world through taxonomies is not automatic, or necessary. Starting from the hypothesis that certain legal cultures resort less to classification than others, I intend to explore the actual meaning of the act of classification. Based on the study of the British constitutional order’s specific case, my research aims to explain and analyze different possible decoding methods. In so doing, I will confront representations of political entities produced by French, British and Canadian scholarly discourse.

Atagün Mert Kejanlıoğlu – doctoral candidate

He obtained another master’s degree in Fundamental Public Law from University Paris 1 Panthéon-Sorbonne in 2016 with his dissertation on Turkish and French presidency.

Project: Unconstitutional Constitutional Amendments : an Example of Abusive Constitutionalism? (2018 – )

In a world where populism is on the rise, constitutions are also increasingly under attack. The reason is simple: constitutions include legal mechanisms designed to protect the values of constitutional democracy. Yet, unlike many other authoritarian regimes, populists play the game by its rules and amend the constitutions by methods that seem to be constitutional. This tendency is one of the main threats to constitutionalism, and therefore to the protection of democracy, human rights and diversity. As populists see the “people” as a unity that can express its will without any limits and directly through referenda, one needs to decipher the role of the “people” in constitutional amendments.

This research intends to explain to what extent the authority of the “people” to amend the constitution is restricted contrary to populist claims. I mainly argue that there are limits regarding how the will of the “people” can be expressed. Contrary to what populists assert, I contend that the will of the “people” cannot be easily determined solely through a referendum process. I use examples from international human rights law, critical constitutionalism, and federalism to illustrate this argument.

Project: Le consociationalisme, principe structurant du fédéralisme coopératif au Canada? (Is Consociationalism a Structuring Principle of Cooperative Federalism in Canada?) (2020 – 2023)

My postdoctoral research project proposes to examine the extent to which the theory of consociationalism (or consociational democracy) could serve as a structuring principle for understanding cooperative federalism in Canada. By methodically examining different materializations of cooperative federalism, I will seek to determine the degree to which the main consociational pillar, which is the search for accommodation between political elites, allows for a better understanding of the dynamics that animate executive federalism between the partners of the federation, as well as the interpretation that the courts make of the different norms that apply to cooperative federalism.

Catherine Mathieu – Doctoral Student

Catherine Mathieu holds both a bachelor’s degree in Public Affairs and International Relations and a Bachelor of Laws from Université Laval. After completing a master’s degree in Constitutional Law while working as an advisor at the Canadian Intergovernmental Affairs Secretariat, she clerked at the Supreme Court of Canada for the Right Honourable Chief Justice Beverley McLachlin.

Project: Fédéralisme et protection du consommateur au Canada à la lumière du droit européen (Federalism and Consumer Protection in Canada in Light of European Law) (2018 – 2023)

My thesis examines the issues raised by the interrelationship and overlap between federal and provincial consumer laws. It aims to contribute to a better understanding of the impacts of Canadian federalism on the protection of consumer rights. It also seeks, by studying the specific case of consumer law, to analyze the evolution of the jurisprudential conception of federalism and of the doctrines guiding the interpretation of the division of powers.
