Criminal Appeal: The Lawyer Must Prove a Special Mandate from Their Client

Imagine the scene: you are the owner of a flat in Mougins, implicated in a case of construction without planning permission. Your lawyer, convinced that the judgment is unfair, decides to appeal. But a few months later, the Court of Appeal tells you that your appeal is inadmissible. Why? Because your lawyer did not have a special mandate to act on your behalf. This is the trap that the Court of Cassation closed in a judgment of 27 November 2012 (No. 11-85.130).

This decision, often unknown to litigants, reminds us of an essential rule: in criminal matters, a lawyer can only lodge an appeal if the person concerned has previously appointed him as their counsel in the forms prescribed by law. Otherwise, the appeal is void. But what does that actually change for you, as an owner, tenant or property professional in the Alpes-Maritimes?

In this article, I will break down this decision, explain how it applies in practice, and give you advice to avoid finding yourself in an inextricable situation. Whether you are in Antibes or Grasse, these rules concern you.

The Facts: A Story that Happens Every Day

Mr X, a landowner in Mougins, is under investigation in judicial proceedings on suspicion of fraud in a property sale. He chooses a lawyer, Mr Y, and officially informs him of this choice by a declaration to the registry of the investigating judge, in accordance with Article 115 of the Code of Criminal Procedure. The investigation continues, but Mr X changes lawyer along the way. He appoints Mr Z, but without making a new official declaration to the registry. Mr Z, considering that his client's rights are being violated, lodges an appeal against an order of the investigating judge.

Problem: Mr Z had not been formally appointed by Mr X in the forms provided for by Article 115. The investigating chamber of the Aix-en-Provence Court of Appeal declares the appeal inadmissible. Mr X appeals to the Court of Cassation, arguing that the lawyer does not need a special power to appeal, and that tacit appointment is sufficient. The Court of Cassation dismisses his appeal: it confirms that while the lawyer does not need a special power (a signed document authorising a specific act), he must nevertheless have been previously chosen by the party and this appointment must be officially registered with the registry of the investigating court.

In short, the lawyer cannot act as a simple agent without a pre-existing relationship with his client. This relationship must be formalised. In this case, since Mr Z had not been regularly appointed, his appeal was void.

The Reasoning of the Court — Explained

The Court of Cassation relies on two texts: Article 115 of the Code of Criminal Procedure (which governs the appointment of a lawyer during the investigation) and Article 502 of the same Code (which provides that an appeal may be lodged by the lawyer without a special power, but on condition that he is regularly constituted). The combination of these texts imposes a dual condition: the lawyer must have been chosen by the party, and this choice must be declared to the registry of the investigating judge, dated and signed by the registrar and the party.

In other words, the lawyer who makes a declaration of appeal does not have to produce a special power (a written document authorising him to act for that specific act), but he must already be the lawyer of the person in the context of the judicial investigation. This prior appointment is a substantive formality. Without it, the lawyer has no standing to act.

Note, however, that the Court of Cassation makes clear that this is a rule specific to criminal procedure during the investigation. Before trial courts, the rules are different. What few people know is that this requirement of formal appointment aims to protect the person under investigation from untimely appeals made in their name without their consent. The judges therefore favoured legal certainty over procedural flexibility.

undefined, I have come across cases where lawyers lodged appeals without a clear mandate, sometimes even after the client had changed lawyers without saying so. Result: months of procedure wasted and unnecessary costs. This decision puts an end to these practices.

What This Changes for You — Practical Implications

For owners or tenants implicated in criminal proceedings (for example for illegal works, nuisances, or serious tenancy disputes), this decision has immediate consequences. If you change lawyers during the investigation, you must imperatively make a new declaration to the registry of the investigating judge. Without this, your new lawyer will not be able to lodge a valid appeal.

Let's take a concrete example: you are an owner in Antibes, and you are prosecuted for converting a garage into a studio without planning permission. You choose a first lawyer, but after a few months, you prefer to change. If you do not formalise this change with the registry, your second lawyer will not be able to appeal an unfavourable order. You risk losing your right of appeal.

For property professionals (agents, developers, notaries), who may face criminal proceedings for breaches of planning or construction rules, this rule is crucial. If you are under investigation, ensure your lawyer is regularly appointed from the start of the investigation. If you change lawyers, inform the registry immediately by an official declaration.

If you are in this situation, you must check that your lawyer has been appointed by a declaration to the registry, signed by you and the registrar. If in doubt, ask him for a copy of this declaration. You can also contact the registry to confirm.

Four Tips to Avoid This Type of Dispute

• Always formalise the choice of your lawyer: as soon as you are under investigation or the subject of a criminal complaint, sign a declaration of choice of lawyer at the registry of the investigating judge. Do not rely on a verbal agreement or tacit mandate.
• If you change lawyers, make a new declaration: do not assume that the registry is informed. You must make a new official declaration for each new lawyer. Otherwise, the old lawyer remains the only one authorised to act, and the new one will not have standing to appeal.
• Keep a copy of the signed declaration: keep a document proving that you have appointed your lawyer. This will avoid later disputes.
• Check your lawyer's acts: if your lawyer lodges an appeal, ask him if he has standing to do so. A serious lawyer will confirm that he is regularly constituted. If in doubt, consult the registry.

Further Reading: Related Case Law and Developments

This decision is part of a consistent line of case law from the Court of Cassation. Already, in a judgment of 14 December 2010 (No. 10-86.321), the Criminal Division had held that a lawyer who lodges an appeal without having been previously appointed in accordance with Article 115 renders the appeal inadmissible. The 2012 decision merely confirms this position, insisting on the need for a formal appointment.

One might wonder about a contrary development: some lawyers argue for greater flexibility, considering that the will of the person under investigation can be inferred from circumstances (for example, the lawyer's presence during interrogations). But the Court of Cassation remains firm: only the official declaration is binding. This rigour protects the litigant against unwanted appeals.

For the future, it is unlikely that the case law will evolve, because this rule guarantees the security of procedural acts. The courts will therefore continue to require a formal appointment. undefined lawyers must be particularly vigilant at the first appearance.

In Practice: What to Do

FAQ: Frequently Asked Questions

1. What if my lawyer lodges an appeal without my having officially appointed him? Contact another lawyer immediately to check the regularity of the procedure. It may be possible to regularise the situation before the Court of Appeal rules on admissibility.
2. Can I appoint my lawyer by email or ordinary letter? No. The law requires a declaration to the registry, dated and signed by you and the registrar. An email or ordinary letter is not sufficient.
3. What are the time limits for making this declaration? Ideally, at your first appearance before the investigating judge. If you change lawyers during the investigation, make the declaration as soon as possible. There is no deadline, but it is better to act quickly.
4. Does this rule also apply in correctional matters (Criminal Court)? No, this decision specifically concerns the investigation phase. Before the Criminal Court, the rules for constituting a lawyer are different, but it is always prudent to formalise the mandate.
5. What does my lawyer risk if he lodges an appeal without a mandate? The appeal will be declared inadmissible, and you could hold him professionally liable for fault. Better to prevent.
