Outline of Final Research Achievements

The results of this research are the following four points.
First, the rationale for the use of evidence that may be restricted in the trial after the pretrial arrangement procedure and its specific rules were clarified. Second, based on the possibility of restricting evidence in the trial, the range of fact and evidence that the parties should assert and request in the pretrial arrangement procedure are shown. Third, I clarified how to arrange the issues and evidence necessary and sufficient for the fruitful trial by using the concept of relevancy as a criterion for selecting assertions and evidence. Fourth, I showed a model for arranging issues and evidence from the perspective of evidence law, using the case where the issue was the restriction of self-defense doctrine, and a example of dynamic evidence regulations, using the recording of interrogation as a material.
