The time spent in this treatment will, after its completion, be deducted from the duration of the prison sentence. If the offender has completed the treatment successfully, this may lead to a suspension of the sentence and finally to its remission. Under the terms of this Act, treatment especially means residential treatment, mostly in officially recognized private institutions. The institutions providing the treatment are obliged to inform the competent enforcement authority of any discontinuation/dropout of treatment. If the offender does not carry on with the treatment, the suspension of the sentence shall be revoked and its execution continued.
