In order to solve the corresponding problems from total-sum fine system while maintaining it, fine system has changed several times over the years. Especially since the imprisonment in a workhouse as a substitution for pecuniary penalty emerged as a serious problem, there have been improvements to it. Also, to prevent offenders with higher fines from abusing the substitution system without paying their fines, the standard for imprisonment in a workhouse was legalized(Criminal Act Article 70 ①). In addition, “The Act on special cases concerning the execution of fine defaulters’ community service work” was entered into force to resolve the difficulties of offenders who cannot afford to pay even lower fines. Moreover, suspension of execution for punishment of a fine was recently legalized(Criminal Act Article 62 ①). The introduction of suspension of execution for punishment of a fine can be underestimated since it isn't any crucial improvement for using imprisonment in a workhouse as a substitution but only a partial supportive measure. However, it also has such meanings as follows; it can prevent the darker side of substituting an imprisonment for a fine at the sentencing phase, it can solve the contradiction that imprisonment which is heavier punishment could be suspended of execution while pecuniary penalty couldn't, and it can provide another forcing alternative other than imprisonment in a workhouse. Although suspension of execution for a fine will be less used than suspension of execution for an imprisonment because both are already in common with preventing the dark side of imprisonment itself. And also since most of the cases concluded with punishment of a fine are summary order cases, it can be predicted that probation, social service orders and orders to attend a lecture are not going to be imposed often with it. But there will be some cases using suspension of execution for a fine, and probation, social service orders and orders to attend a lecture will be also imposed along with it. In order for the new suspension system to be settled and function, a predictable sentencing standard should be adopted. Investigation Conducted before Ruling should be actively used, the system of cancellation of suspension of execution should be supplemented by partial cancellation, inclusion of the already carried-out disposition of imposition, and so on. Also, coordination should be placed to avoid duplication with “The Act on special cases concerning the execution of fine defaulters’ community service work”
