For the past few years, lots of effort has been put into the sphere of legal ethics in Taiwan. In the aspect of Taiwan legal ethics culture, the promotion of legal ethics shall respond to the condemnation of judicial injustice, put the ideal of judicial justice into practice, and improve the judiciary reputation and social confidence. However, how do we comprehend the idea of judicial justice? Why do the judiciary system, procedural design, and judgments, which ought to accomplish the ideal of judiciary justice, constantly bring us into the disputes of judiciary injustice? I believe the purpose of promoting legal ethics is to acquaint jurists with the relevant obligations, and make them strictly abided by the limits of interpersonal relationship. Moreover, the social communicating functions of legal ethics shall be elaborated positively by urging the legal profession to keep cautious while dealing with the difficulties of interests and values measuring. As the condemnation of judicial injustice emerges, the jurists, especially judges and prosecutors, should always reflect: Is the terms of justification and application sufficient? Is the discourse of legal reasoning crystal to the public? Which interests and values measuring difficulties have I encountered during the trail? Are those positions and discussions properly revealed in the judicial documents (including judgments, indictments, and documents of not to prosecuted and deferred prosecution)? In sum, a discussion platform of judicial justice must be built to contain the social examinations and professional explanations. Thus legal ethics shall be capable of being used to promote judicial justice.
