When placement under judicial supervision has been ordered against a person sentenced to a term of criminal imprisonment of fifteen years or more for one of the offences referred to in article 706-53-13, the regional court referred to in Article 706-53-15 may, in accordance with the procedures set out in this article, decide to extend all or part of the obligations to which the person is subject, beyond the limit set out in Article 723-29, by placing them under security surveillance for a period of two years.
The regional court for secure detention is seized by the sentence enforcement judge or the public prosecutor six months before the end of the measure.
Placement under secure surveillance may only be ordered, after medical expertise has established the persistence of dangerousness, in cases where:
1° The obligations resulting from registration in the automated national judicial file of perpetrators of sexual or violent offences appear insufficient to prevent the commission of the crimes mentioned in article 706-53-13;
2° And if this measure constitutes the only means of preventing the commission, the likelihood of which is very high, of these offences.
Security surveillance may be extended under the same terms and conditions and for the same duration if the conditions set out in this article continue to be met.
The provisions of the last four paragraphs of Article 706-53-19 shall apply.
The regional court for secure detention may also, in accordance with the procedures set out in Article 706-53-15, order secure supervision for a person placed under judicial supervision from whom all sentence reductions have been withdrawn, pursuant to the first paragraph of l’article 723-35, following a breach of the obligations to which he or she was subject under conditions that reveal a risk that he or she will again commit one of the offences mentioned in article 706-53-13. Security surveillance applies as soon as the person is released.
