(1) After expiration of the period set in accordance with section 95 (1), the court may, upon request of the execution authority, or if it is responsible for enforcement itself, order coercive detention ex officio if
1. the regulatory fine, or the assessed instalment thereof, has not been paid,
2. the person concerned has not made his or her insolvency known (section 66 (2) number 2b),
3. he or she has been instructed in accordance with section 66 (2) number 3, and
4. no circumstances are known on which his or her insolvency can be based.
(2) If it is revealed in accordance with his or her economic circumstances that the person concerned cannot be expected to pay the amount of the regulatory fine immediately, the court grants an easier means of payment, or leaves the decision thereon to the enforcement authority. An order already given for coercive detention is rescinded.
(3) The period of coercive detention involving a regulatory fine may not exceed six weeks; it may not exceed three months for several regulatory fines assessed in one regulatory fining decision. The period is fixed by days in consideration of the amount of the regulatory fine to be paid, and may not be extended subsequently, but may be reduced. Coercive detention may not be repeated on account of the same amount.
