A suspended sentence is a type of criminal sanction that is imposed in the case of illegal behavior by the perpetrator of a criminal act and determines that the sentence, to which the perpetrator has been sentenced, will not be carried out if the perpetrator does not commit a new crime during the probationary period and fulfills certain obligations. Suspended sentence is one of the younger criminal sanctions created by the transition from a monistic system to a dualistic one, and ultimately to a pluralistic one, when there are significant changes in the field of criminal sanctions and everything begins to be directed towards the future and the ultimate goal that the perpetrator no longer repeats the criminal acts he has committed in the past. It is an institute that was created quite by accident in the middle of the 19th century, and today it is divided into Anglo-Saxon and Continental legal system. The historical development of suspended sentence in the Republic of Croatia can be observed through three stages, which led to the suspended sentence as we know it today (suspended sentence according to the Criminal Code from 1951, suspended sentence according to the Basic Criminal Code of the Republic of Croatia from 1993 and suspended sentence according to the Criminal Code from 1997.). The new Criminal Code from 2011. no longer recognizes warning measures, so a suspended sentence becomes a mere modification of the sentence with the fact that the core remains the same, the application of a suspended sentence is limited to cases in which the perpetrator has been sentenced to a prison sentence of up to one year or has been sentenced to a fine and at the same time becomes an alternative to short-term prison sentences. The court's assessment is the most important for the conditions for the imposition of a suspended sentence. The partially suspended sentence is a new institute that was not known in Criminal Code form 1997., but was introduced only in Criminal Code form 2011. reason for this is the abandonment of conditional sentence as a sui generis criminal sanction. Pursuant to Criminal Core from 2011., with regard to the reasons and the court's decision, two types of revocation of a suspended sentence are prescribed, namely mandatory revocation and optional revocation. Although the institution of suspended sentence, in its pure form as known by criminal law, does not exist in juvenile criminal law, we will still look at its role and application because there is an institute very similar to it, which is called the reservation of the right to impose the sentence of juvenile incarceration but there are some differences. The importance of the institute of suspended sentence is manifested in its application in practice, it is the suspended sentence that is by far the most represented criminal sanction in the Republic of Croatia.
