A criminal justification for industrial actions is provided in the Amendment of the Settlement of Labor Disputes Law, which has been adopted in 2009. However, the amendment does not provide relief for most of the labor protest activities in our country. An immediate resolution still lies in the theoryof substantial justification under the criminal law. Due to the unique historical and social context in Taiwan, the societyholds a more conservative attitude toward the labor activities. Under such a context, the appropriate illustrations are required for the practice. This paper aims at providing some practical guidelines and criteria. The core of criminal infringement is the breach of legal goods. While determining the criminal justification, we mayintr oduce a multiple consideration to the criminal legal matrix firstlythr ough linking the legal goods with the constitutional rights. Then we use the principle of "superior interest" and the "penalized breach of the law" theoryto extend the probabilityo f justification. Three cases are demonstrated in this paper. In addition, the paper deals with the constitutional status of "right to dispute" and the industrial actions as "civil disobedience".
