Background
M. [K] [W] was under criminal investigation for drug offenses and criminal association with recidivism. He filed a motion to annul certain documents in the investigative file. The instruction chamber of the Versailles Court of Appeal rejected his motion on 28 November 2025, upholding the validity of evidence obtained through various police investigative techniques. M. [W] appealed to the Court of Cassation.
Among the disputed investigative acts were: (1) installation of a geolocation device on his vehicle in a private residential parking lot; (2) police access to multiple law enforcement and administrative databases including the criminal records database (TAJ), the national driver’s license database (SNPC), and the pre-employment declaration database (DPAE); and (3) the identity and authorization of officers who accessed these databases.
The Court’s Holding
The Court of Cassation issued a partial cassation, vacating the lower court’s decision in part while upholding it in part. On the geolocation issue, the Court found that although the prosecutor’s authorization did not explicitly permit entry into the private parking lot outside statutory hours, the evidence was admissible because the parking area was a common area of a residential building and officers were acting within their judicial police authority in compliance with constitutional safeguards.
On database access, the Court made critical distinctions. Regarding the TAJ and SNPC consultations by two officers on 27–29 September 2023 based on authorizations dated 27 April and 5 May 2022, the Court held that the instruction chamber properly verified the officers’ individual authorizations. The Court noted that absent evidence of revocation, it need not search for whether authorizations had been withdrawn. However, the Court annulled the decision on two separate grounds: (1) the DPAE database access by officer [F] [U] in September 2023 occurred outside the statutory framework limiting such access to illegal labor investigations, yet the lower court upheld access without examining whether it could be justified under Articles 60-2 or 77-1-2 of the Code of Criminal Procedure; and (2) officer [S] [T]’s claimed access to these databases on 4 March 2022 could not be justified by an authorization document dated 5 May 2022—after the access occurred—and the lower court contradicted itself by both acknowledging this chronological impossibility and denying its legal consequence.
Key Takeaways
- Police access to employment databases (DPAE) is strictly limited to investigations of illegal labor offenses under Articles L. 8271-1 et seq. of the Labor Code; general judicial police authorizations cannot bypass this statutory restriction.
- Authorization documents must be dated before the access they purport to permit; post-hoc authorizations cannot validate prior database consultations.
- Lower courts must provide reasoned justifications addressing the parties’ essential contentions and may not rest decisions on legal theories that contradict their own findings of fact.
- Access to criminal records and driver license databases may be upheld if individual officer authorizations are verified, absent evidence suggesting revocation or lapse.
Why It Matters
This decision tightens judicial oversight of police database access, particularly for sensitive employment records. French law restricts DPAE access to investigations of labor-law violations; this ruling confirms that prosecutors and investigating judges cannot circumvent that restriction by invoking general criminal investigation authority. The decision reinforces that statutory limits on police database access are not advisory—they define the jurisdiction itself. For practitioners, the ruling underscores the importance of proper documentation, chronological consistency, and explicit legal bases for investigative measures, and signals that courts reviewing police procedure will examine whether access fell within its statutory scope, not merely whether officers held a credential to access that database in some context.
The partial cassation returned the case to a differently constituted instruction chamber for reconsideration of whether officer [U]’s DPAE access and officer [T]’s claimed database access could be justified under alternative legal provisions, and whether officer [T]’s consultations on 4 March 2022 violated procedural rules.
