The court shall be applied an extraordinary mitigation of the penalty or may even conditionally suspend the execution of the penalty, with respect to a perpetrator who, co-operating with others in the commission of an offence, reveals information pertaining to the persons involved therein or essential circumstances thereof, to the agency responsible for its prosecution. § 4. Upon a motion from the state prosecutor, the court may apply an extraordinary mitigation of the penalty or even conditionally suspend the execution of the penalty with respect to a perpetrator, who, irrespective of any explanation provided in his case, revealed and presented to the agency responsible for prosecution, essential circumstances, not previously known to that agency, of an offence subject to a penalty exceeding 5 years deprivation of liberty. § 5. In the cases referred to in § 3 and 4, the court, in imposing the penalty of deprivation of liberty for up to 5 years, may conditionally suspend the execution of the penalty for a probation period of up to 10 years, if it recognises that, in spite of not serving the penalty, the perpetrator would not commit the offence again; the provisions of Articles 71 through 76 shall be applied accordingly. § 6.
