(1) The court shall revoke the suspension of a custodial measure if the convicted person

1.  commits an unlawful act during the period of supervision;

2.  grossly and persistently violates directions under section 68b; or

3.  persistently evades the supervision and guidance of the probation officer or the supervision authority

and there is reason to believe that the purpose of the measure requires his detention. The 1st sentence above shall apply mutatis mutandis if the reason for revocation arose between the decision on suspension and the start of the supervision (section 68c(4)).

(2) The court shall also revoke the suspension of a measure pursuant to section 63 and section 64 if there is evidence during the operational period of the supervision that unlawful acts are to be expected from the convicted person as a result of his condition and the purpose of the measure requires his detention.

(3) The court shall further revoke the suspension if evidence, which has come to its attention during the period of the supervision and which would have led to the suspension being denied, shows that the purpose of the measure requires the detention of the convicted person.

(4) The period of detention before and after the revocation must not in its totality exceed the maximum statutory period for the measure.

(5) If the court does not revoke the suspension of the measure the measure shall be deemed terminated at the conclusion of the operational period of supervision.

(6) Services which the convicted person has rendered in fulfilment of directions shall not be reimbursed.
