Section 15d 
1.  Conditional release may be postponed or denied in cases where: 
a.  the convicted offender has been admitted by reason of mental disease or defect to a custodial 
institution for the treatment of persons detained under an entrustment order and the treatment 
needs to be continued; 
 b.  it has been shown that the convicted offender seriously misbehaved after the commencement 
of his sentence, which serious misbehaviour can be evidenced by: 
1°. serious suspicions or a conviction for a serious offence;

2°. behaviour that resulted several times in the imposition of a disciplinary punishment during 
enforcement of the sentence; 
c. 
after the commencement of the convicted offender’s sentence, he seeks or makes an attempt 
to avoid serving this sentence; 
d.  the setting of conditions cannot sufficiently reduce the recidivism risk for serious offences or if 
the convicted offender does not state that he is prepared to comply with the conditions; 
e.  the custodial sentence which is being enforced is based on a final judgment of conviction 
rendered by a foreign court and enforcement of the sentence has been transferred in 
accordance with the applicable treaty, insofar as the possibility of postponement or denial of 
conditional release led the foreign authority to agree to the transfer. 
 
2.  Conditional release may also be postponed or denied if the facts or circumstances, referred to in 
subsection (1)(b), (c) or (d), occurred during the period to be deducted from the custodial sentence 
under section 27(1). 
3.  If Our Minister of Justice is of the opinion that there is cause to postpone or deny the conditional 
release for a specific period on any of the grounds, referred to in subsection (1), he shall request 
the Public Prosecution Service to submit an application requesting such postponement or denial.
