Lawyers at the Conseil d’État and the Court of Cassation, who are government officials, are professionals specialising in the technique of cassation and cross-disciplinary legal experts. 

They are brought together in a professional association which represents the profession, provides assistance to litigants looking for a lawyer, offers mediation if necessary and ensures the discipline of the profession (link https: // ordre-avocats-cassation.fr).

They work to stringent professional and ethical standards and they provide genuine advocacy in the defence of their clients’ interests, whilst ensuring that their arguments are credible, fair and respectable. 

Strictly independent, lawyers at the Conseil d’Etat and the Court of Cassation must ensure that, for every case they handle, they give their clients an objective opinion as to the likelihood of their appeal succeeding, and the risks involved. This fundamental task includes advising clients against lodging or supporting appeals that have no chance of success. 

More generally, lawyers at the Conseil d’Etat and the Court of Cassation contribute to access to justice and to the public service mission carried out by all the courts in which they work and, first and foremost, the Conseil d’Etat and the Court of Cassation.
