This paper considers the development of new clinical and medical practices in the early 2000s in France, after the adoption of legal reforms aiming at the prevention of sexual infractions and the protection of minors. The paper explains how the reform led to the creation of a new form of punishment for sexual offenders, l'obligation de soin (therapeutic obligation), which can be described as long-term mandatory therapeutic monitoring. This paper offers an analysis of the implementation of this measure from the standpoint of the specialized mental health care unit which were entrusted the mission of caring for the new group of convicted patients, i.e., patients sentenced to undergo mandatory therapy, after this legal reform. In the new regime these mandatory therapies created, clinicians are tasked to combine their conventional mission of care for the patient in the present, with the judicial mandate of detecting and preventing the patient's relapse qua recidivism in the future. Mobilizing ethnographic examples that evidence the way clinical care comes to encompass a penal mandate of long-term surveillance of convicted patients, I argue that the dual injunction of procuring care while preventing relapse-recidivism constrains the psychodynamic forms of clinical intervention deployed by French clinicians, realigns both psychiatric and clinical interventions along penal lines, and revives interest in some of the diagnostic categories and aims of criminal psychiatry which were important for the development of psychiatry in France.
