Although probation plays a pivotal role in social treatment, there is no means to properly cope with violations of compliance requirements. In particular, this problem is revealed in probation conducted according to suspension of execution and parole, which account for most of the adult probation. First, there are no standards for actions that can be taken when violating compliance requirements. It also has structural limitations in that the legal effects on similar violations are different, the gap between sanctions is severe, and the probation period cannot be secured. To improve these problems, this paper proposed a short-term improvement plan and a long-term improvement plan that does not require a revision of the law. First, as a short-term improvement plan, it was proposed to prepare a step-by-step and specific practical manual to supplement the effectiveness of special compliance requirements by actively utilizing the system of addition, change, and deletion of requirements. As long-term improvement measures, the systematization of the law based on compliance, improvement of detention, the extension of probation period, partial revocation of a suspension of execution, mandatory parole, and flexible operation of parole was suggested as alternatives.
