After graduating from the Ecole Nationale d'Administration (ENA), a prestigious institution for French civil servants, Emmanuelle Mignon began her career at the Conseil d'Etat. Her roles included serving as a rapporteur in the litigation and internal affairs divisions, leading the legal research center, acting as a government commissioner, and holding the position of assessor.

Her profound understanding of public law and governmental operations greatly benefits the firm's clientele in both advisory and litigation engagements. Her tenure at the Conseil d'Etat and within French administration saw her coordinating the preparation of diverse legal, constitutional, legislative, regulatory, and European texts.
