Yes, in the event of difficulties, it is possible to refer a case to the consumer ombudsman for the profession of barristers to the Council of State and the Court of Cassation, at the following address:

Consumer ombudsman for the profession of barristers to the Council of State and the Court of Cassation

Mr Jean Barthélémy

5 Quai de l'Horloge, 75001 Paris


It is a procedural act by which the administrative court (State Council, Administrative Appeal Court, administrative court,…) appeals prior to the deadline; usually two months from the notification of the decision, sentence or ruling.

This action, which interrupts the appeal deadline, is transmitted via dematerialised means to the State Council and a certain number of administrative courts, and on paper to the others.

The appeal includes a brief reminder of the factual circumstances followed by an account of various legal measures, to be referred to at a later stage and concluding with the annulment of the decision, judgement or ruling in question.

It is a lodging carried out on behalf of the party bringing the matter before the appeal court simultaneously interrupting the deadline.

In a civil context, this lodging is made by the Councils’ lawyer to the Clerk of Courts’ office via e-communication with an e-signature.

With regard to criminal law, it is made at the Clerk’s Office of the court which pronounced the ruling challenged by the party itself or by its representative. The Appeal Court lawyer must register at the Clerk’s Office within a month from the lodging.

The filing of an appeal or a protective appeal allows for the time-limit to be interrupted. It also enables the Councils’ lawyer to foresee the appeal’s likelihood of success, or, providing the appeal has reasonable grounds to be put forward, to compile a legal brief accompanied by a legal notice. At the Court of Appeal, having read the consultation concerning the appeal’s probability of success or legal brief and notice, the lawyer and their client can decide to either pursue the appeal or to stand down.

Generally (excluding emergency procedures), the time limit for filing a brief for an appeal is three months.

The dossier is assigned to the State Council where it is studied by a team of legal professionals.

Having studied the document, it is then rendered either non-eligible, if the Council deems the grounds stated are not adequate to justify an appeal, or eligible.

The procedure then becomes an opposition and the defence files a defence case.

Other cases and particularly a response case can also be potentially filed. Following this written procedure, a public reporter is generally appointed and the affair is carried to a court hearing during which the rulings will be announced.

The affair is considered and the final ruling given, generally, two to three weeks following the hearing.
