環境影響評估法制的內容規定無疑作為預防原則之實現。其中，環境影響評估審查結論公告目前被認定為行政處分，又稱為多階段行政處分或多階段審查程序。一旦第一階段有條件通過環評環境影響評估，即無須再進行第二階段環境影響評估。然而，有條件通過環評之「條件」的性質為何？其爭論有：附款之行政處分、未來履行義務事項說以及須經審查委員會之開會討論、審查事項等說。再者，「審查結論嗣後撤銷」與「自始未通過審查結論」之效力不同應分別從：環評法之立法沿革、行政程序法「無效」法理以及「多階段程序」等三大面向觀之，始能一探究竟。評估審查結論被撤銷後，人民得提起之救濟途徑為何？其爭議有：非課予義務訴訟、課予義務訴訟、給付訴訟等。本文最後提出結論與建議。

The legal provisions of“Environmental Impact Assessment Law”are regarded undoubtedly as the implementation of the precautionary principle. Among them, the announcement about the review conclusion of the environmental impact assessment is now been identified as an administrative sanction, also known as multi-stage administrative sanction or multi-stage review process. Once of a conditional adoption through environmental impact assessment in the first phase, the second phase of an environmental impact assessment is needed no longer to be carried out. However, how is the nature of the “conditional adoption” through environmental impact assessment? It´s argument are: additional administrative sanction, matter of the future obligations and the matter to be subject to discussion, review by committee etc. Moreover, the differently applied effectiveness between “the review conclusions of the environmental impact assessmen be revocated subsequently” and the “original non-adopted review conclusions through environmental impact assessmen” should be finded out separately from three concepts: legislative history of Environmental Impact Assessment Law, “invalid” legal theory in the Administrative Procedure Act and “multi-stage process”. The review conclusion of the environmental impact assessmen has be revocated subsequently, how about the relief types after it´s revocation? It´s disputes are: non-imposed duty litigation, imposed duty litigation, pay litigation. Finally, this dissertation makes conclusions and recommendations.
