Code of Civil Procedure Article 397

Where the performance ordered by a final and binding judgment has not been effectuated, and a change of circumstance after the conclusion of the oral argument renders such performance manifestly unfair, one of the parties may reinitiate an action to claim that the performance or other effects ordered by the original judgment shall be amended insofar as no remedy provided by other legal proceedings is available.The provision of the preceding paragraph shall apply mutatis mutandis to settlement, mediation, or anything with the same effect as a final and binding judgment.
中文原文 民事訴訟法第397條
確定判決之內容如尚未實現,而因言詞辯論終結後之情事變更,依其情形顯失公平者,當事人得更行起訴,請求變更原判決之給付或其他原有效果。
但以不得依其他法定程序請求救濟者為限。
前項規定,於和解、調解或其他與確定判決有同一效力者準用之。
