(401/2015) Section 14 – Ordering enforcement of the remaining sentence (780/2005) (1) On the request of the prosecutor, the court may order that the remaining sentence be enforced if the convicted person commits a new offence during the probationary period for which in the consideration of the court he or she should be sentenced to unconditional imprisonment and for which charges have been brought within one year of the termination of the probationary period. In so doing one joint sentence of unconditional imprisonment shall be imposed for the remaining sentence to be enforced and the sentence imposed for the offence committed during the conditional release period, combined with the sentences of imprisonment to be imposed for other offences, in accordance with the provisions of Chapter 7. However, the remaining sentence shall not be deemed the more severe penalty referred to in section 5, subsection 2 of said Chapter. In determining the length of the remaining sentence to be enforced the court shall take into consideration the provisions of subsection 2. (2) Enforcement of the remaining sentence may be waived in particular if: (1) most of the probationary period had been served before the offence referred to in subsection 1 had been committed, (2) the remaining sentence is brief, (3) the sentence to be imposed for the offence committed during the probationary period is brief, or (4) due to the sanction to be imposed on the offender for the offence committed during the probationary period or the other consequences of the sentence the joint sentence would lead to an unreasonable result. (3) The court may also order that a part of the remaining sentence shall be enforced, in which case the conditional release continues with the former probationary period. (4) When the court orders that the remaining sentence shall be enforced, it shall state the length of the remaining sentence or part thereof to be enforced.
