環境議題帶來的不僅是環境風險可能造成的危害，亦使行政權力作用獲得一個正當性的反思機會。本文企圖找尋憲法定位的行政正當性來源在制度前端解決層出不窮的爭執與衝突，並結合環境領域中的新興管制治理模式，以彌補環境相關爭議最終訴諸司法訴訟曠日廢時與環境利益保護實效性不佳之弊端。又環境影響評估在整體環境行政決策中具有舉足輕重的法制度定位，其高度專業與政治性格使環境影響評估成為極重要的民眾參與場域。此一民眾參與功能的落實將攸關後續環境行政決策品質的正當與否。因而，本文擬透過行政正當性的各種來源檢視我國環境影響評估程序之民眾參與，並從司法實務反思現況及制度應然面之建置。其最終目在的係在促使環境行政之相關決策能獲得更妥適的決策。 Environmental issues not only bring the potential harm of environmental risk, but also make the executive power to get a rethink chance of administrative legitimacy.
