Bringing your constitutional challenges
before the courts
Through priority constitutional questions, litigants can challenge the constitutionality of statutory provisions that may infringe rights and freedoms protected by the Constitution. These proceedings require a deep command of constitutional law and the ability to construct a rigorous and persuasive argument before the courts.
Our team draws on the experience of former senior civil servants, including a former member of the Conseil d’État, to provide the highest level of expertise. We assist clients in preparing and presenting constitutional challenges before administrative and judicial courts, through to the Constitutional Council.
Our work includes assessing admissibility, drafting submissions, managing proceedings before the referring courts, and preparing observations before the Constitutional Council. We also intervene upstream to assess the strategic value of raising a constitutional challenge in ongoing litigation.
