本文研究歐洲監察使的起源、職權行使方式與具體貢獻。歐洲監察使的職權設計，採取軟法的方式，可受理歐盟人民對歐盟 行政機構與單位之不當行政的陳情案，處理方法有友善解決方案、批判性評論、草擬建議和特別報告。本文研究從1995年第一任歐洲監察使起到2005年間，其主要的貢獻。其主要貢獻領域為一、澄清不當行政概念，二、推動良好行政行為規範，三、促進資訊公開方面的努力外，四、處理政府契約的遲延給付問題、契約糾紛問題及五、促進具體人權。根據本文研究發現，雖然歐洲監察使的處置方式並無拘束力，僅有建議性質，但在其努力下，歐盟各行政機構都盡量配合遵守其建議。此外，其除了個案，也會利用向歐洲議會提出的特別報告，推動制定或修改法規。其協助推動制定了歐洲良好行政行為規範，並推動歐盟各機構制定或修改其資訊公開的規定。從此面向來看，歐盟監察使可以用較柔性的方法，促成法規的修正，而達到保障人權的功能。
