Disappearance of Estelle Mouzin: ECHR finds that French courts acknowledged deficiencies in justice system and compensated for resulting non-pecuniary damage.

The Court has declared inadmissible the application in the case of Mouzin v. France.

The case concerned the judicial investigation and proceedings in relation to the disappearance of the applicant’s 9-year-old daughter. Her body was never found. The Court’s decision was based both on the criminal conviction of Ms Olivier in 2023 and 2024 and on a 2025 judgment acknowledging the State’s gross negligence as a result of the defective operation of the public justice system.
