(1) The court shall order the suspended sentence to take effect if the convicted person:

1.  commits an offence during the operational period showing that the expectation on which the suspension was based, has been disappointed;

2.  grossly or persistently violates directions or persistently evades the supervision and guidance of the probation officer, thereby causing reason for fear that he will re-offend; or

3.  grossly or persistently violates conditions.

No 1 of the 1st sentence of this subsection shall apply mutatis mutandis if the offence was committed in the interim period between the decision suspending the sentence and its becoming final; it shall also apply in cases of the subsequent fixing of aggregate sentences if the offence was committed in the period between the decision on the suspension of a judgment included in the aggregate sentence and the date when the aggregate sentence became final.

(2) The court shall not order the suspended sentence to take effect if it is of the opinion that it would suffice

1.  to impose further conditions or directions, in particular to place the convicted person under the supervision of a probation officer; or

2.  to prolong the operational period or period of supervision.

In cases pursuant to No 2 above the operational period must not be prolonged for more than one-half of the originally imposed period.

(3) The convicted person shall not be compensated for services rendered in fulfilment of conditions, offers, directions or assurances. If a suspended sentence is put into effect the court may credit services which the convicted person has rendered in fulfilment of conditions under section 56b(2) 1st sentence Nos 2 to 4, or related offers under section 56b(3) towards the sentence.
