Section 43. Duration of preventive detention

In a sentence of preventive detention, a time frame is set that normally should not exceed 15 years, and that may not exceed 21 years. For offences with a penalty limit of imprisonment for a term of up to 30 years, the court may set a time frame not exceeding 30 years. If the convicted person was under 18 years of age at the time of the act, the time frame normally should not exceed 10 years, and may not exceed 15 years. On application of the prosecuting authority, the court may by judgment extend the set frame by up to five years at a time. An extension application must be filed with the district court no later than three months before the end of the period of preventive detention.
The court should also set a minimum term of preventive detention which may not exceed 10 years. In cases where the court sets a time frame exceeding 15 years, however, the court may set a minimum term not exceeding 14 years. In cases where the court sets a time frame exceeding 21 years, the court may set a minimum term not exceeding 20 years.
