The French criminal justice currently goes through a diversification of cases treatment processes. This diversification is the result of many factors, both endogenous and exogenous. It is the focal point of the evolution in theoretical approaches regarding criminal phenomena, social expectations of an effective criminal justice, and of a new process of justice management. Prosecution choices reflect a logic of criminal policy and also a logic of rationalization of the criminal justice management. The idea of «prosecution choices» becomes a new legal category that articulates the response to criminality. Its theoretical range modifies the approach of the prosecution. The diversification of prosecution choices has consequences on both conception and typology of the criminal trial and on courts organisation. The monolithic criminal trial inherited from the 1808 French code of criminal investigation becomes a more plural trial, with a renewed configuration and multiple purposes. The notion of « orientation schematics » illustrates such evolution. A legislative consideration of this notion would lead to a better structuring of the criminal justice response. The criminal justice system's organization is also affected, as well as the parties situation in the trial. Consultation and delegation mechanisms appeared. The new judicial management builds on this diversification in the prosecution choices. The criminal trial must integrate the digital transformation that should lead to the construction of a digital criminal trial.
