Police custody and delay in notification: automatic nullity according to the Court of Cassation

Imagine: you are a property owner in Arles, and your tenant is suspected of an offence. The police arrive, place him in police custody at 2:30 PM. But the investigating judge is not informed until 7:30 PM, i.e. five hours later. Can this lapse of time, seemingly innocuous, vitiate the entire procedure? The answer is yes, and the Court of Cassation forcefully recalled this in a judgment of 29 February 2000.

This decision, rendered under number 99-84.899, concerns Article 154 of the Code of Criminal Procedure. But what does this actually change for you, as a property owner or tenant in Istres or elsewhere? In short, if you are involved in criminal proceedings, compliance with time limits for notification is crucial. Any delay, even a short one, can lead to the annulment of essential acts such as an interview.

In this article, we will analyse this decision, understand what it means in practice, and give you advice on how to react if you face a similar situation. Because, in my practice, I have encountered cases where this type of nullity changed the course of a case.

The facts: a story like many others

The case concerns a person under judicial investigation (an inquiry conducted by an investigating judge). The judge had issued a rogatory commission (an order to the police to investigate) to a judicial police officer (OPJ). In this context, the OPJ placed the person in police custody at 2:30 PM. However, the investigating judge was not informed of this measure until 7:30 PM, a delay of five hours.

The person in police custody raised the nullity of his interview, arguing that this delay violated Article 154 of the Code of Criminal Procedure, which requires that the judge be informed "as soon as possible". The indictment division (intermediate appellate court) rejected this request, considering that the information had been given orally at the beginning of the custody, as required by Article 63-1 of the same code.

But the Court of Cassation (the highest judicial court) censured this reasoning. It held that any delay, not justified by an insurmountable circumstance, necessarily prejudices the interests of the person in custody. In this case, the judge had been informed only five hours after the start of the custody, without any valid explanation. The nullity of the interview was therefore incurred.

The reasoning of the court — analysed

The legal basis of this decision is Article 154 of the Code of Criminal Procedure, which provides: "The investigating judge must be informed as soon as possible, by the judicial police officer acting in execution of a rogatory commission, of any placement in police custody." This article is an essential protection for the person in custody, as it allows the judge to control the regularity of the measure.

In essence, the investigating judge is the "guardian" of individual liberty during the investigation. If he is not notified in time, he cannot verify whether the custody is necessary or proportionate. The Court of Cassation therefore considered that the mere fact of the delay, without valid excuse, causes automatic prejudice to the person concerned. In other words, it is not necessary to prove that the delay had concrete consequences: it suffices that it exists.

This reasoning marks an important evolution: before this judgment, some courts required the person to demonstrate actual prejudice. Now, the unjustified delay alone suffices to entail nullity. However, note: the Court specifies that if an insurmountable circumstance (such as a storm or network failure) had prevented the notification, the delay could have been excused. But in this case, nothing of the sort was invoked.

What few people know is that this decision also applies to interviews conducted during police custody. If the judge was not informed in time, any interview report can be annulled, which considerably weakens the prosecution.

What this changes for you — in practice

If you are a landlord in Istres, and your tenant is involved in a criminal case, this decision can have an indirect impact: if the procedure is annulled, it can influence related disputes (for example, an eviction for neighbourhood disturbance). But above all, if you yourself are placed in police custody, you must be vigilant about compliance with time limits.

For tenants, this decision strengthens your rights: if you are in custody, any delay in notifying the judge can lead to the annulment of interviews. For example, if the police place you in custody at 10 AM and the judge is not informed until 4 PM, without valid reason, your lawyer can request the nullity of all interviews conducted in the meantime. This can invalidate confessions or statements.

For buyers or co-owners, the lesson is more general: compliance with legal time limits is fundamental. In a property dispute, a delay in a notification (for example, a notice to quit) can also lead to nullities. But here, the principle is the same: the court automatically sanctions any unjustified delay.

If you are in this situation, you must immediately note the exact time of the start of custody and the time when the judge was informed. Your lawyer will then be able to check compliance with Article 154. In practice, a delay of more than two hours without serious justification can be challenged.

Four tips to avoid this type of dispute

• Note the times precisely: at the start of custody, ask the police officer to indicate the exact time of placement and the time of notification to the judge. Record these times in writing.
• Request a copy of the report: after your interview, you are entitled to obtain a copy of the report mentioning the times. Check that they match your notes.
• Contact a lawyer quickly: as soon as you are informed of the custody, call a lawyer. He can immediately check the regularity of the procedure and raise a nullity if necessary.
• Do not sign anything without checking: if you notice a difference between the actual time and the time mentioned, do not sign the report without consulting your lawyer.

Further reading: related case law and developments

This decision is part of a line of judgments protecting the rights of persons in police custody. For example, the Court of Cassation has already held that the failure to inform the judge as soon as possible vitiated the procedure (Crim., 12 May 1998). The 2000 judgment confirms and reinforces this position by specifying that the delay is necessarily prejudicial.

Since then, the trend has been towards increased monitoring of time limits by the courts. Judges no longer hesitate to annul acts for even minor delays, as long as they are not justified. This means that police officers must be particularly vigilant in informing the judge almost instantaneously.

For the future, this case law could be extended to other measures depriving liberty, such as customs detention or administrative detention. Specialised lawyers regularly exploit these nullities to defend their clients.

FAQ: Frequently asked questions

1. What is a rogatory commission? It is a written order from the investigating judge to the police to carry out investigative acts (searches, interviews, etc.).
2. What time limits are considered "as soon as possible"? Case law generally considers that a delay of more than two hours without justification is excessive.
3. What to do if I notice a delay? Note the times, inform your lawyer, and request the nullity of the procedure before the investigating judge or the investigation chamber.
4. Can I obtain compensation if nullity is pronounced? Yes, you can claim damages for the violation of your rights, in addition to the annulment of the acts.
5. Does this decision apply to all police custody? Yes, as long as there is a rogatory commission. For flagrante delicto investigations, Article 63-1 applies with different rules, but the principle of speed remains the same.
