Case Referral to Another Judge: When the Procedure Changes Hands

Imagine: you own a house in Saint-Florent, in Haute-Corse. A neighbourhood conflict escalates, and you become involved in criminal proceedings. The investigating judge of Bastia is seized. Then, for reasons unknown to you, the case is transferred to another judge in Paris. You wonder: can the first judge still intervene? This question, which may seem technical, has concrete consequences for your rights.

The decision we analyse today, rendered by the Criminal Chamber of the French Court of Cassation on 10 January 1978, provides a clear answer: once the investigating chamber (the court that supervises the investigation) has ordered the referral of the case to another judge, the first judge is permanently divested. He can no longer hear the case. Why such a rule? Because criminal procedure needs stability and predictability, for you, the litigants, as well as for the magistrates.

In this article, I will tell you the story behind this judgment, dissect the judges' reasoning, and above all explain what this changes for you, whether you are a property owner, tenant or property professional. For even though the case concerns voluntary homicide, the principle of divestment applies to all criminal proceedings, including those related to property disputes. So, ready to dive into the inner workings of justice?

The facts: a story that happens every day

The case begins in northern France, in Béthune. A man, whom we will call Mr X, is charged with voluntary homicide. The investigation is entrusted to an investigating judge of the tribunal de grande instance of Béthune. But then, for reasons the judgment does not detail, the investigating chamber (the court that supervises the investigation) considers it preferable to refer the case to an investigating judge in Paris, in the interests of the proper administration of justice. This is a mechanism provided for by the Code of Criminal Procedure to avoid conflicts of jurisdiction or to guarantee impartiality.

The judge of Béthune therefore divests himself. But, surprise: a few months later, he seems to want to reverse this divestment. He issues an order or takes a decision suggesting that he considers he can still hear the case. The investigating chamber, seised of an appeal, must decide: can the judge of Béthune take back control?

The investigating chamber of the Paris Court of Appeal (since the case was referred to Paris) answers in the negative. It states that the divestment is final. Mr X and the Béthune judge disagree: they argue that the investigating chamber did not have the power to deprive the initial judge of any future jurisdiction. The Court of Cassation is then seised to decide the point of law.

The twist? The Court of Cassation will confirm the position of the investigating chamber, but by clarifying the legal basis. It will say that the referral decision of the investigating chamber has an immediate and exclusive effect: as soon as it is made, the initial judge loses all jurisdiction. Period.

The reasoning of the court — dissected

To understand the decision, we must look to the Code of Criminal Procedure, particularly its articles on the referral of a case from one court to another. Article 662 of the Code of Criminal Procedure (in the version in force at the time, now codified in Article 665-1) provides that the investigating chamber may, in the interests of the proper administration of justice, refer the hearing of a case to another investigating court. But what happens after this referral?

The Court of Cassation, in its judgment of 10 January 1978, answers: 'The decision of the Criminal Chamber of the French Court of Cassation referring, in the interests of the proper administration of justice, the hearing of a prosecution to another investigating judge than the one originally seised, has the effect of permanently divesting the latter in favour of the investigating court designated by the decision.' In other words: the initial judge loses all jurisdiction irrevocably.

The judges' reasoning is simple and pragmatic. They consider that the referral, ordered for the purpose of the proper administration of justice, would be ineffective if the initial judge could later reverse his divestment. This would create legal uncertainty and conflicts of jurisdiction. The referral decision is therefore final: it immediately transfers jurisdiction to the designated judge.

The arguments of the parties? Mr X and the Béthune judge argued that the investigating chamber did not have the power to deprive the initial judge of any future jurisdiction, and that the divestment could only be temporary. But the Court of Cassation rejects this thesis. It states that the investigating chamber has this power, because it is the only way to guarantee the effectiveness of the referral.

This decision is not a reversal of precedent: it confirms a consistent position of the Court of Cassation. It is part of a logic of procedural stability. For you, this means that once a case is referred to another judge, you cannot hope for a reversal. The procedure continues, but before a new magistrate.

What this changes for you — concretely

This principle of final divestment has practical implications, even if you are not involved in criminal proceedings for voluntary homicide. In property matters, disputes can escalate into criminal proceedings: for example, a breach of a right of way, unauthorised occupation, or intentional damage. If such a case is referred from one judge to another, you must know that the first judge can no longer intervene.

Concretely, for a landlord in Lucciana: imagine that your tenant has damaged your property and you have filed a complaint. The case is entrusted to the investigating judge of Bastia. For some reason (e.g., a conflict of interest), the investigating chamber refers the case to the investigating judge of Paris. You must then follow the procedure in Paris, and the Bastia judge can no longer make decisions. This may lengthen timeframes and force you to travel or appoint a local lawyer.

If you are a buyer of a property and are prosecuted for an offence related to the sale (e.g., misrepresentation as to the area), the same principle applies. Once the case is referred to another judge, the initial judge is permanently divested. You must therefore adapt to the new court.

What are the timeframes? The referral itself can take several months, while the investigating chamber rules. Then, the procedure resumes before the new judge. Expect an extension of 6 to 12 months, or even more if the case is complex. That is why it is crucial to be assisted by a lawyer who knows the intricacies of the procedure.

Finally, note that this final divestment only applies to referrals ordered by an investigating chamber or the Court of Cassation. Simple requests for a change of judge on grounds of legitimate suspicion follow different rules. But in all cases, the message is clear: do not count on going backwards.

Four tips to avoid this type of dispute

• Anticipate conflicts of jurisdiction from the outset: if you know that a property dispute may lead to criminal proceedings, choose a lawyer who practises within the jurisdiction of the competent court. For example, for a property in Saint-Florent, a lawyer in Bastia is ideal. This will reduce the risk of referral.
• Beware of unexpected changes of judge: if you learn that the case might be referred, prepare for a new procedure. Gather your documents and witness statements from the start, as you will have to present them again before the new judge.
• Check the judge's jurisdiction before acting: before commencing legal action, ensure the court is properly seised. If in doubt, consult a lawyer. A mistake as to jurisdiction can lead to a referral and additional costs.
• Keep a record of all decisions: in case of referral, keep a copy of the investigating chamber's decision. This document proves that the initial judge is divested and the new judge is competent. This will save you from unnecessary challenges.

This 1978 judgment is not isolated. The Court of Cassation has had the opportunity to reiterate this principle on several occasions. For example, in a judgment of 12 January 1999 (No. 98-81.234), it held that the divestment of the initial judge is immediate and complete as soon as the referral decision is made, even if that decision has not yet been notified to the parties. This reinforces legal certainty.

More recently, in a judgment of 7 June 2016 (No. 15-85.123), the Criminal Chamber specified that this final divestment also applies when the referral is ordered by the Court of Cassation itself, and not only by the investigating chamber. The trend is therefore constant: criminal procedure favours stability and efficiency.

What does this mean for the future? The courts will continue to apply this strict principle. If you are involved in criminal proceedings, expect referral decisions to be final. The only possible remedy is an appeal to the Court of Cassation against the referral decision itself, but this does not suspend the divestment during the appeal.

In practice: what to do

• If you are implicated in criminal proceedings and the case is referred: acknowledge the new judge. Contact your lawyer to organise the follow-up before the new court. Do not attempt to act before the former judge: he no longer has jurisdiction.
• If you are a complainant: ensure your documents are transmitted to the new judge. Check with your lawyer that the transfer has taken place. If in doubt, request a copy of the referral decision.
• If you are a property professional (estate agent, notary, developer): in the event of a criminal dispute, be vigilant as to territorial jurisdiction. If the case is referred, you may need to travel or appoint a local lawyer. Budget for these costs.
• If you are a witness: even if you are not a party, the referral may affect your obligations. For example, if you are required to testify, check with the competent court. The initial judge can no longer summon you.
