Background
Mr. [C] [H], an adult subject to enhanced curatorship, was under formal investigation for aggravated murder and attempted aggravated murder. After initially being held in pretrial detention, he was released under judicial supervision.
On February 16, 2026, the liberty and detention judge revoked his judicial supervision and ordered him back into pretrial detention. Mr. [H] appealed. The Rouen Court of Appeal’s Investigation Chamber annulled the detention order, ordered his release, and placed him under judicial supervision because his curator had not been informed that the liberty and detention judge would conduct an adversarial hearing on his possible detention. The prosecutor general appealed to the Court of Cassation.
The Court’s Holding
The Court of Cassation rejected the prosecutor general’s appeal. It held that notifying the curator that the protected adult would appear before the investigating judge regarding a possible revocation of judicial supervision did not satisfy the separate obligation to inform the curator that the liberty and detention judge had been asked to conduct an adversarial hearing concerning pretrial detention.
The Court further held that failure to provide this separate notice necessarily prejudiced the protected person. The fact that Mr. [H] was represented by counsel did not cure the omission or require counsel to request that notice be sent. The Investigation Chamber therefore properly annulled the order revoking judicial supervision and imposing pretrial detention.
Key Takeaways
- A protected adult’s curator must be notified when the liberty and detention judge is asked to conduct an adversarial hearing on pretrial detention.
- Earlier notice of an appearance before the investigating judge concerning possible revocation of judicial supervision does not satisfy that distinct notice requirement.
- Failure to notify the curator necessarily prejudices the protected adult, even when the adult is represented by a lawyer.
Why It Matters
The decision treats the investigating judge’s proceedings and the subsequent detention hearing as distinct procedural stages requiring separate notice to the curator. Prosecutors and investigating authorities cannot rely on a single initial notice when proceedings move from possible revocation of judicial supervision to an adversarial hearing on detention.
The ruling also establishes a strong consequence for noncompliance: prejudice is inherent in the failure to notify, so a protected defendant need not demonstrate that the omission changed the hearing’s outcome.
