Abstract These days, the Grand Justice of the Judicial Yuan has issued the No. 563 Explanatory Ruling, and in the ruling opinion the terms "the right to learn" and "the right to education" have been used. Thus, an academic freedom issue has been repeatedly and mistakenly treated as a problem about the right to education. That is partly because the Legislature has juxtaposed "the right to learn" and "the right to education" in Article 1 of the Education Essential Law, and partly because the meaning of these two terms is confusing. In the following, this essay will clarify the concepts of "the freedom of learning", "the right to learn" and "the right to education", and then introduce the facts and decision of the No. 563 Explanatory Ruling. The discussion will start from the constitutional protection of academic freedom, and then analyze the protected legal interests of academic freedom. The aim is to set a standard for handling legal disputes concerning universities through discussing constitutional control from formal and substantive aspects. In the end, this essay suggests that judicial institutions when handling cases concerning universities should begin as a protector of academic freedom, and should recognize the academic freedom interests in each case. They should also distinguish the principles of "university autonomy" and "reservation to law", with academic freedom belonging to the university autonomy field. The other matters that do not concern academic freedom should be decided according to law. And, in both fields, themeasures and methods used should be constitutional.
