Reviewing the cases on criminal law last year, the current study aims to collect some adequate cases from the perspective of the content and the judgment criteria of the human right protecting function in criminal law under the constitutional order. The chosen cases have been examined case by case in terms of their consistency with theories, especially the theories which are built by the substantive demands of ”Nulla poena sine lege (no penalty without a law)” due to limiting criminal law, or self-contradiction. In accordance with mentioned above, two interpretations by the Justices of the Constitutional Court will be discussed first. One is Interpretation No.662, which refers to the Convert Imprisonment into Fine; the other is Interpretation No.664, concerning the treatments of the juvenile delinquents in the Juvenile Proceeding Act. The present research discusses further the following issues from last year's criminal judgments: the Principle of Proportionality application in confiscation, the criteria of aggregate offenses, the content of neutral behaviors and the cultural conflict between aboriginal and Chinese cultures. At last, the result of these case observations will be concluded.
