Administrative Litigation Act Article 237-27

If the High Administrative Court determines that the Urban Plan is not unlawful, it shall dismiss the plaintiff's case by a judgement. The same shall apply when the Urban Plan is found violating procedural rules and such violation has been corrected in a lawful manner prior to the conclusion of the oral-argument session in the first instance.
中文原文 行政訴訟法第237-27條
高等行政法院認都市計畫未違法者,應以判決駁回原告之訴。
都市計畫僅違反作成之程序規定,而已於第一審言詞辯論終結前合法補正者,亦同。

English translation for reference only; the Chinese text prevails. Not legal advice.
