In Taiwan, the Grand Justices perform substantial functions of the Constitutional Court. Therefore, the ”judicial interpretations” made by the Grand Justices bear the nature of ”court decisions” and should be ”executed” accordingly so as to realise the decisions in real terms. According to Article 17 (II) of the Law to Govern the Disposition of Cases by Grand Justices of the Judicial Yuan, ”After making a judicial interpretation, the Grand Justices may notify concerned authorities and finalise the procedures and measures taken to execute the interpretation”. A judicial interpretation may be thereby executed under the law. There are theories to elaborate the execution of judicial interpretations including the nature and contexts of ”execution”, the concept as compared to relevant terms, the conditions and contexts of the notification, the definition of concerned authorities and remedies for the execution. This article will examine and review judicial interpretations concerning the ”execution” against the theories to make elaborative conclusions and concrete suggestions.
