Background
M. [F] [K] was placed under formal investigation on July 22, 2024, for offenses including assassination and criminal conspiracy. He sought annulment of numerous investigative acts and records, challenging matters that included an unsigned record of a telephone conversation, the notice given to the investigating judge when he was placed in police custody, the audiovisual recording of an interview, and investigators’ use of facial recognition and other information from the French criminal-records database known as TAJ.
He also challenged officers’ authorization to consult TAJ and the national DNA database, statements he made when a passport was shown to him during a search, the opening and seizure of an abandoned bag found beneath a vehicle, and a specialized police unit’s extraction and organization of cellphone data. The Rennes Court of Appeal’s Investigation Chamber refused to annul any material, and M. [K] appealed to the Court of Cassation.
The Court’s Holding
The Criminal Chamber dismissed the appeal. It held that the signature formalities governing witness interviews did not apply to the caller’s brief, spontaneous, and imprecise statements. Notice that M. [K] had been placed in custody was sufficient because the investigating judge had already issued a search warrant for him concerning the same conduct and legal classifications, and therefore had personally assessed the grounds for custody. The challenged interview had also been audiovisually recorded, as shown by the investigating judge’s inspection of a recording matching its date, time, and duration.
The Court held that a nullity application in the current proceeding could challenge consultation of TAJ, but not the legality of the earlier collection, recording, or retention of information in that database; those matters belong to the separate procedure for deletion of stored data. The Investigation Chamber had adequately verified the officers’ authorizations to consult TAJ and the DNA database. A further challenge concerning records imported from another proceeding failed because M. [K] had not asserted before the lower court an interest in seeking their annulment.
The Court also held that M. [K]’s spontaneous acknowledgment that a seized passport was his and stated his true identity was a non-self-incriminating recognition of an object, not an interview requiring counsel. Opening a bag abandoned on a public street was not a search governed by the statutory rules for premises searches. Finally, a specialized police unit could extract, organize, and flag potentially relevant cellphone data under Articles 60-3 and 99-5 of the Code of Criminal Procedure; because those operations did not interpret the data, they were not a judicial expert examination.
Key Takeaways
- Brief, spontaneous information supplied to police is not necessarily a formal witness interview subject to signature requirements.
- A procedural-nullity motion may test investigators’ consultation of TAJ, but challenges to the original collection, recording, or retention of TAJ data must proceed through the statutory deletion process.
- Recognizing a seized object without police questioning is not an interview when the statement is non-self-incriminating, and searching a bag abandoned in public is not treated as a premises search.
- Police specialists may extract and organize cellphone data without appointment as judicial experts when their work involves no interpretation of the data.
Why It Matters
The decision clarifies the boundaries between formal evidentiary acts and preliminary or technical police work. It identifies when witness-interview safeguards, custodial-interview protections, premises-search rules, and judicial-expertise procedures do—and do not—apply.
It also channels challenges involving police databases into distinct procedural routes: consultation in a pending case may be attacked through nullity proceedings, while the legality of stored data’s original collection and continued retention generally must be contested through the statutory deletion mechanism.
