Constitutional Court Procedure Act Article 42

(Petition for Rehearing) For cases concerning constitutionality of laws or disputes between constitutional organs, except as provided in Paragraphs 2 or 3 of this Article, no one shall lodge a petition in respect of the same impugned laws or disputes that have been previously declared short of unconstitutionality or otherwise decided pursuant to the Constitution in a Judicial Yuan Interpretation or a judgment of the Constitutional Court.All courts, persons, or the legislative or executive authorities of the local self-government bodies may, in accordance with the procedural provisions of Chapters 3 or 7, lodge a petition to request the Constitutional Court to alter a Judicial Yuan Interpretation or a judgment of the Constitutional Court by which a legal provision has been previously declared not unconstitutional, if they consider that the amendment of the Constitution or relevant laws or material changes in social circumstances necessitates the reconsideration of such interpretations or judgments.Under the conditions specified in the preceding Paragraph, the highest organs of the state may lodge a petition to request the Constitutional Court to alter such Judicial Yuan Interpretations or judgments of the Constitutional Court concerning disputes between constitutional organs in accordance with the procedural provisions of Chapter 4.
