Since most occupations are licensed in Taiwan, especially based on the professionalism and the judicial interpretations about article 86, section 2 of the Constitution. The situation above caused the control of professions is designed as licensure which use examinations to identify one’s abilities to meet the demands from the judicial interpretations. Though the kinds of regulations absolutely restrict the right to work our judicial interpretations overlooked it. Furthermore, the relation among the right to work, article 86, section 2 of the Constitution and the power of controlling professions which are thought as the power of the Examination Yuan has been neglected for a long time. As a result, I’d like to analyze the problems about professions and its control, and what contents did article 86, section 2 of the Constitution the control of professions.
