Environmental impact assessment documents with the meaning of Taiwan’s EIAA, which are binding on the developers, contain three major parts: the main text of EIA review reports, conditional approval and commitments made in the environmental impact statement or during the review meeting by the developers, when it comes conditional approval of the environmental impact assessment review of Art. 43 EIAA Enforcement Rules. Although the foregoing conditions and commitments are different in legal disputes, on the one hand, whether their legal admissibility and limitations are correctly understood, could ensure that the EIA system is not abused. On the other hand, these have been widely adopted in the reports of the EIA review, therefore, it gradually became the focal point of administrative litigation. However, relevant disputes have not been fully discussed in the lecture and the relevant judgments have also appeared inconsistent positions. Therefore, it is worthwhile to study them.
