(1) Good-conduct measures

  Good-conduct measures are implemented when the behavior of a probationer/parolee has become stable during the period of supervision, and he/she has come to be considered unlikely to commit repeat offenses. There are two types of measures as follows: an indeterminate sentence parolee who has served his/her minimum term is granted termination of indeterminate sentence as if he/she has completed his/her sentence; an offender given suspension of execution of sentence with probationary supervision is granted provisional discharge from probationary supervision.
  In 2006, 446 offenders given suspension of execution of sentence with probationary supervision were granted provisional discharge from supervision, and no parolee was granted termination of indeterminate sentence (Source: Annual Report of Statistics on Rehabilitation).

(2) Bad-conduct measures

  Bad-conduct measures are taken when a probationer/parolee has violated the conditions of supervision or committed offenses during the period of supervision. By way of revocation of parole or revocation of suspension of execution of sentence, a subject parolee is imprisoned again in a penal institution, and a subject offender given suspension of execution of sentence has his/her suspension revoked. Also, a parolee whose whereabouts has become unknown is subject to suspension of parole supervision and his/her sentence is interrupted. In 2006, 345 were subject to suspension of parole supervision (Source: Annual Report of Statistics on Rehabilitation).
  Where a parolee/probationer fails to reside in a fixed abode or there are sufficient reasons to suspect that he/she has violated the conditions of supervision, and he/she fails or would fail to respond when summoned by a probation office director, he/she is apprehended under a warrant of arrest issued by a judge. Following the decision to commence the examination on a bad-conduct measure, he/she is detained in an appropriate institution for a fixed term. In 2006, including juveniles, 403 probationers and parolees were apprehended and 373 were detained in this manner (Source: Annual Report of Statistics on Rehabilitation).
