La convergence des jurisprudences de la Cour de cassation et du Conseil d'État

This dissertation aims at describing how the two Supreme Institutions -- the Board of State and the Court of Cassation --, despite their respective traditions and status were able to make their Jurisprudences convergent. Beginning with an historical Introduction, the study goes in details into the reciprocal attraction of the the Board of State and of the Court of Cassation based on shared goals (Part I). This convergent movement is discussed according to both Jurisprudences (Title 1), then in relation with the Jurisprudences of the Disputes Tribunal of the Constitutional Council and of the European Courts (Title 2). Part II offers a methodological approach explaining how the sources of these Jurisprudences are selected in order to solve normative conflicts (Title 1). A cross-movement consisting in loans and exchanges of technics between both Institutions occurs for the sake of Law unity and in defense of the public and individual Rights (Title 2).
