Police custody during a search: what the Court of Cassation says

Imagine: you are at home, in Villeneuve-lès-Avignon, on a quiet evening. Suddenly, police officers knock on your door, search warrant in hand. They ask you to stay available while they search your house. You are not a suspect, just present. But during the search, a seized object catches their attention. A few minutes later, you are told you are being placed in police custody. Is this legal?

This is precisely the question decided by the Court of Cassation in a judgment of 12 June 2013 (No. 13-80.893). A decision that concerns any owner or occupant likely to witness a search. And which recalls a fundamental rule: your rights must be respected from the moment you change status from a mere witness to a suspect.

In this article, I explain this decision for you, its practical consequences, and the reflexes to adopt if you face a similar situation. Whether you are an owner in Pont-Saint-Esprit, a tenant in Nîmes, or an ordinary citizen, what you are about to read may save you a lot of trouble.

The facts: a story that happens every day

It is 22 May 2012, in Monnaie (37). Mr Y..., owner of a house, sees the gendarmes arrive with a rogatory commission for a search. They arrive around 8 p.m. Mr Y... is present, he is not a suspect at this stage. The judicial police officer (OPJ) keeps him available under Article 56 of the Code of Criminal Procedure (which allows a person present to be detained to obtain information about seized objects).

The search continues. Around 10 p.m., the investigators discover evidence that casts suspicion on Mr Y.... They then decide to place him in police custody (a measure depriving him of liberty for questioning). But they notify him of his placement at 10 p.m. with retroactive effect to 8 p.m., the time of their arrival. Then, at 11:50 p.m., a second notification is made.

Problem: between 8 p.m. and 10 p.m., Mr Y... was detained without being informed of his rights (right to silence, to a lawyer, to notify a relative). The retroactivity of the police custody is challenged. The case goes up to the Court of Cassation.

The reasoning of the court — explained

The Court of Cassation had to answer a specific question: from when must a person present during a search benefit from the rights attached to police custody?

The legal basis is Article 56 of the Code of Criminal Procedure, which allows the OPJ to keep on the premises any person likely to provide information. But this detention is not police custody: it does not entitle the person to the usual guarantees (lawyer, silence, etc.).

The Court distinguishes two phases: as long as the person is merely detained for information, it is lawful. But as soon as evidence of participation in an offence appears, the person must be placed in police custody, with immediate notification of rights. In short, the trigger is the appearance of serious or corroborating evidence (elements suggesting that the person has committed an offence).

In this case, the Court validates the placement in police custody, but criticises the retroactivity: police custody cannot begin before notification of rights. In other words, if the OPJ detained Mr Y... without rights from 8 p.m. to 10 p.m., that period must be considered a simple detention (lawful because based on Article 56). Police custody begins at 10 p.m., when rights are notified.

What few people know: this decision is a confirmation of prior case law (Crim., 30 June 2010, No. 10-80.892). It recalls that defence rights are a priority, even during a search.

What this changes for you — practically

If you are the owner or occupant of a property being searched, here is what you need to remember:

• For the owner-landlord: if your tenant is a suspect, you may be kept on the premises to provide information (e.g., tenancy agreement). But if the police find objects at your home that implicate you, you must be placed in police custody with rights notified immediately. Example in Pont-Saint-Esprit: an owner present during a search of a rented garage sees drugs seized. If he is suspected of complicity, police custody must be immediate.
• For the tenant: you are on the front line. If you are present, you may be detained without rights as long as you are merely a witness. But as soon as the investigators consider you involved, they must notify you of your rights. In practice, if you are asked to stay without being told why, ask if you are in police custody. If the answer is no, you can in principle leave (unless the OPJ detains you under Article 56, which is lawful).
• For the buyer: before buying, check that there is no ongoing criminal proceedings concerning the property. A search may reveal past offences that could be held against you (e.g., trafficking).

In figures: police custody can last 24 hours (renewable to 48 hours for certain crimes). Without notification of rights, any evidence obtained during the irregular period may be annulled. undefined, I have seen cases where failure to notify led to the nullity of the proceedings.

Four tips to avoid this type of dispute

• Know your rights before any search: note the number of a lawyer available 24/7. As soon as you are detained, ask if you are in police custody. If yes, exercise your right to silence and to a lawyer.
• Do not sign any statement without understanding: investigators may ask you to sign statements. Take time to read, and refuse if you are unsure. You have the right to consult a lawyer beforehand.
• Document the timeline: note the time the police arrived, the time you were notified of your rights, the time police custody began. This will be useful if you challenge the procedure.
• If in doubt, contact a lawyer: even after the search, if you believe your rights have been violated, you may bring an action for nullity. Do not delay: time limits are short (before trial).

Further reading: related case law and developments

This decision is part of a protective line of defence rights. Already in 2010, the Court of Cassation had ruled that detention on the premises without police custody was limited in time (Crim., 30 June 2010, No. 10-80.892). More recently, the Criminal Chamber recalled that notification of rights must be made at the start of the measure depriving liberty (Crim., 4 February 2014, No. 13-85.329).

The trend is clear: judges are increasingly demanding regarding compliance with formalities. The 2013 judgment confirms that mere presence at the scene does not justify prolonged deprivation of rights. For the future, we can expect any retroactivity of police custody to be systematically censured.

Checklist before acting

What to do if you are detained during a search:

1. Stay calm and do not physically resist.
2. Ask immediately: "Am I in police custody?" If yes, ask to exercise your rights (lawyer, silence, notify a relative).
3. Note the exact time of each event (arrival of police, notification, etc.).
4. If you are placed in police custody without notification, do not sign anything and contact a lawyer as soon as possible.
5. After the search, keep all documents given to you (statement, summons).
