The court may order the execution of the penalty, if the sentenced person in the probation period flagrantly breached the legal order, and, in particular, if he committed an offence other than that specified in §1, has not paid the fine, has evaded supervision, or failed to fulfil the obligations or penal measures imposed. § 3. The court may order the execution of the penalty if, after the sentencing decision was rendered but before it became valid and final, the perpetrator flagrantly breached the legal order, and in particular if he committed an offence within that time. § 4.
