(1) If a single or aggregate sentence of imprisonment of not less than two years has been imposed for intentional offences, or not less than one year for an offence listed in section 181b, has been fully served, supervision shall commence upon the release of the convicted person. This shall not apply if a custodial measure of rehabilitation and incapacitation is enforced immediately afterwards.

(2) The court may waive supervision if there is reason to believe that the convicted person will not commit further offences without supervision.
