Police Custody and Administrative Detention: Can an Old Irregularity Nullify Everything?

Imagine: you are a property owner in Argelès-sur-Mer, and you rent an apartment to a tenant who, after run-ins with the police, ends up placed in administrative detention. The procedure seems regular, but suddenly, an old flaw – an irregularity in a police custody dating back several days – is invoked to annul the detention. You wonder: can such an irregularity invalidate the measure? And above all, what can you do to prevent your situation (rental, neighbourhood, etc.) from being disrupted by these legal complications?

The question every property owner or real estate professional asks is simple: how far back can judges go to annul a procedure? The answer, provided by the Court of Cassation in a decision of 6 June 2012 (No. 11-11.384), is clear: an irregularity affecting an initial police custody that does not immediately precede the detention does not justify annulling it.

This decision, rendered in the context of immigration law, directly concerns property owners and real estate professionals: it limits cascade annulments and protects the stability of administrative situations. Let's decode this story and its practical implications, particularly in the jurisdictions of Perpignan, Argelès-sur-Mer and Prades.

The Facts: A Story Like Many Others

Mr X, a Lithuanian national, was arrested on 23 November 2010 at 7:15 a.m. by the police in the jurisdiction of Perpignan. Placed in police custody, he presented identity documents that proved to be dubious. The investigators carried out checks, and Mr X was placed in police custody a second time on 24 November, then a third time, after which he was placed in administrative detention pending removal from the territory.

The problem? During the first police custody, no doctor was called to examine Mr X, contrary to the requirement of Article 63-3 of the Code of Criminal Procedure (compulsory medical examination for any person in police custody). This lack of a medical certificate was discovered by Mr X's lawyer, who applied to the First President of the Court of Appeal to annul the detention.

The First President, considering that this absence of a certificate had deprived Mr X of the possibility of proving that his state of health was incompatible with police custody, and that it had infringed the rights of the defence, annulled the procedure. But the Court of Cassation, seised by the Public Prosecutor, quashed this decision. Why? Because the irregularity concerned the first police custody, which was not immediately followed by the detention: in the meantime, two other police custodies had occurred. The direct causal link was broken.

The Reasoning of the Court — Analysed

The Court of Cassation relies on two texts: Article 63-3 of the Code of Criminal Procedure (which requires a medical examination in police custody) and Article L. 552-1 of the Code on the Entry and Residence of Foreigners and the Right of Asylum (which governs administrative detention). In short, it recalls that to annul a detention, the alleged irregularity must affect the immediately preceding measure of deprivation of liberty. In other words, one cannot go back indefinitely in time to find a flaw and bring everything down.

The lower courts had considered that the absence of a medical certificate during the first police custody had necessarily infringed the rights of the defence. But the Court of Cassation responded: "Not so fast!" It considered that the alleged irregularity affected the first police custody, which did not immediately precede the contested detention measure. Consequently, it had no impact on the validity of the detention.

However, caution: this is not a carte blanche for the authorities. If the irregularity had concerned the last police custody (the one directly preceding the detention), annulment would have been justified. The decision thus sets a temporal limit: only irregularities in the measure of deprivation of liberty immediately preceding the detention can be invoked.

This solution is consistent with a logic of proportionality and legal certainty. The judges want to prevent old flaws with no direct link from paralysing otherwise regular procedures. What few people know is that this decision was rendered in a context where cascade annulments were frequent, creating insecurity for property owners and professionals who rent to irregular immigrants.

What This Changes for You — Practical Implications

For landlord owners: if you rent to a foreign tenant and that tenant is placed in administrative detention, you can no longer hope to have the detention annulled by invoking an old irregularity in a police custody that is not immediately preceding. For example, if your tenant in Prades was placed in police custody three days before his detention, and that first police custody was irregular, that will not suffice to annul the detention. You must therefore focus on the regularity of the most recent measure of deprivation of liberty.

For tenants: this decision limits your remedies. If you believe you were the victim of an irregularity during an old police custody, know that it will not affect a subsequent detention. Conversely, if the irregularity concerns the police custody immediately preceding the detention, you can challenge it. Practically, if you are in Argelès-sur-Mer and are arrested then placed in detention, check whether a medical examination was carried out during the last police custody. If not, you have a ground for annulment.

For real estate professionals (agents, property managers): this decision reassures you about the stability of situations. You can advise your owner clients that detention procedures will not be weakened by old flaws. This secures rental contracts, particularly in high-demand areas like Perpignan, where rentals to foreigners are common.

If you are in this situation, you must act quickly: the time limits for challenging a detention are very short (48 hours in general). For an owner, an annulment of detention could lead to the tenant's return, with consequences for the lease. It is therefore better to anticipate.

Four Tips to Avoid This Type of Dispute

• Check the regularity of procedures from the outset: if you are involved in a police custody procedure, immediately demand a medical examination. Do not let this right pass, as it can be crucial for challenging a subsequent detention.
• Keep all documents: carefully retain medical certificates, police custody records and detention placement decisions. These documents allow proof of the regularity or irregularity of the procedure.
• Consult a lawyer without delay: as soon as you are informed of a detention measure, seek advice. A specialised lawyer will be able to verify whether the last police custody is regular and, if necessary, initiate a challenge within 48 hours.
• Anticipate the consequences on the lease: if you are an owner and your tenant is placed in detention, prepare to manage the absence: what about the rent? the notice period? Find out about the legal obligations in case of temporary disappearance of the tenant.

Further Analysis: Related Case Law and Evolutions

This 2012 decision is part of a line of case law that tends to limit cascade nullities. For example, in a judgment of 5 July 2011 (No. 10-88.123), the Court of Cassation already ruled that the irregularity of a police custody does not necessarily affect a subsequent procedure if there is no direct link. The trend is therefore towards securing procedural acts, to prevent formal flaws from paralysing public or administrative action.

Conversely, some earlier decisions had allowed broader annulments, considering that any irregularity in the chain of deprivations of liberty could vitiate the whole. The 2012 decision marks a partial reversal: it sets a clear limit: only the immediately preceding irregularity is taken into account.

For the future, we can expect judges to continue refining this notion of "direct link". undefined, I have encountered cases where the question arose for successive police custodies with very short durations. Case law will have to specify what constitutes an acceptable "immediacy". In the meantime, this decision remains a reference for lawyers and litigants.

Checklist Before Acting

• Question: Can I challenge an administrative detention if the first police custody was irregular?
  Answer: No, if that police custody is not immediately preceding the detention. Only the irregularity of the last measure of deprivation of liberty can be invoked.
• Question: What should I do if I am placed in police custody then detention?
  Answer: Demand a medical examination at each police custody. Keep the certificates. If the last police custody is irregular, you can apply to the judge within 48 hours.
• Question: My tenant is in detention. Can I terminate the lease?
  Answer: Detention is not an automatic ground for termination. You must wait until the end of the measure or prove a prolonged absence. Consult a lawyer for the modalities.
• Question: What are the time limits for action?
  Answer: The challenge against a detention must be filed within 48 hours of notification of the measure. After this period, you lose the possibility to challenge.
• Question: Can an owner be penalised if his tenant is in detention?
  Answer: No, unless you facilitated the offence. However, you must comply with the lease rules and not take unilateral decisions without legal grounds.
