Section 13 
1.  A convicted offender sentenced to imprisonment may be admitted to a custodial institution for the 
treatment of persons detained under an entrustment order, if he is eligible for such admission by 
reason of mental disease or defect; in that case sections 37c, 37d and 37e shall apply mutatis 
mutandis. 
2.  If a convicted offender has been sentenced to imprisonment in combination with detention under 
an entrustment order with compulsory treatment, a review of whether the convicted offender should 
be placed in a custodial institution for the treatment of persons detained under an entrustment 
order shall be conducted regularly. Further rules pertaining to this review shall be set by or 
pursuant to Governmental Decree. These rules shall relate to and include in any case the 
frequency of the reviews, the procedure to be followed, including the consultation of behavioural 
experts, and the way in which the reviews should be conducted. 
3.   Admission under subsection (1) and discharge shall be governed by rules to be set by 
Governmental Decree by order of the Minister of Justice, issued after at least two behavioural 
experts of different disciplines - one being a psychiatrist - who have examined the person in 
question have issued a reasoned, dated and signed opinion. Such opinion shall be given jointly by 
the behavioural experts or by each of them separately. 
4.  A convicted offender may file an appeal against the decision pertaining to admission, the decision 
pertaining to discharge and the decision denying admission contrary to the recommendation of the 
court given in accordance with the provisions of section 37b(2) with the Council for the 
Administration of Justice and the Protection of Juveniles within four weeks after the decision has 
been notified to him. The provisions of Chapter XVI of the Treatment of Persons detained under an 
Entrustment Order (Framework) Act [Beginselenwet Verpleging ter Beschikking Gestelden] shall 
apply mutatis mutandis.
