Outline of Final Research Achievements

The goals of this research project is to elucidate the admissibility standards of bad character and similar fact evidence, to propose the procedure in which judge decide the admissibility and to suggest how to examine these evidences which are only for sentencing at trial. I examined the various attitudes toward these evidences in the common law countries (US, England, Canada, and Australia) and the civil law country (Germany).
The conclusions are as follows. These evidences should be allowed when probative value outweigh prejudice and misleading effect, whether these evidences are used for substantive purpose or for impeachment. In pretrial arrangement hearing, judge should decide the admissibility after prosecutor and defense lawyer discuss how the material fact can be inferred from these evidences based on rule of thumb. Judge have to distinguish the procedure for guilty and that for sentencing so that fact-finder will not misuse these evidences which are only for sentencing.
