(Consolidation and Division of Proceedings)

The Constitutional Court must pronounce its decision within three months after the closing of oral argument. The time limit for pronouncement may be extended by two months when necessary.

(Open Court)

The Judicial Yuan shall make the rules governing public attendance in oral argument sessions of the Constitutional Court, the audio and video recordings of oral arguments, and their use and storage.
