本文以法制史料為基礎，回顧清末變法修律的歷程，嘗試透過各種法制素材，還原當時樣貌。並於歷史考察的過程中，探索當時時代背景下所面臨的外在環境，思考當時以日本為師的可能原因。 其次，本文嘗試整理、分析清末新刑律草案的用語，並將之置於傳統中國律典的發展脈絡，以及中日文化交流的過程下，探討其詞語特徵。 最後，針對立法當時來自地方督撫上奏意見所提到的語言問題，本文嘗試以構詞和語法的觀點，提出不同面向的思考。希望透過清末變法修律過程中所遭遇的語言問題，探尋可供現代借鏡之處。

模糊是語言的主要特色之一，這與法律語言的終極目標—精確恰恰相反。在追求精確的過程中，在法律制度裡的某字或某術語該做何解釋，往往有許多爭議。法官如何在模糊與精確當中取得平衡?又如何確保每項法律公正地適用於每個人與每起個案?本文試圖探討這兩個極端—模糊與精確—如何交織與競合，從法律語言學的觀點對爭議個案提供解釋，並進一步解決法律制度中各種語言詮釋的問題，其中以刑法的語言為主要研究標的。為了闡釋文字的意義，本文嘗試以框架語意學、檢查表理論和原型理論來架構出法律語言的框架。本文之另一項目的是要觀察刑法法條中的語言現象，是否能反映出刑法的精神與特質。 / Vagueness is one of the major characteristics of language, which happens to be contradictory to the ultimate goal of legal language—precision. In the process of pursuing precision, there are a variety of disputes over what interpretations words or terms in the legal system should be made. How do judges strike the balance between vagueness (uncertainty) and precision (certainty) and affirm that every rule be justly applied to every individual and every case? This research attempts to explore how these two extremes interweave and compete and to provide explanations for some controversial cases and offer a perspective from forensic linguistics to solve the problems among the various interpretations of the language used in the legal system, in this case, the Criminal Law. To elucidate the meaning of words, this study tries to construct the frame of legal language with linguistic approaches such as frame semantics, checklist theory, and prototype theory. Another objective of the research is to see whether the linguistic phenomena observed in the system can reflect and convey the spirits and essences behind the Criminal Law.

本論文是以曾引起臺灣社會輿論熱烈關注的玻璃娃娃案為研究起點，進而探究法律語言、法律論證與日常語言之間的關聯性。首先，分析玻璃娃娃案的四件民事判決，並聚焦在這些判決文內容的法律語言、法律論證與日常語言。其次，從玻璃娃娃案判決的相關新聞報導中，探討日常語言與法律語言。再者 ，檢視與評論民法學者對玻璃娃娃案的第一、第二審判決的個案分析，藉此探究法律語言、法律論證與日常語言之間的關聯性，緊接著運用民法請求權基礎的架構來重新檢視玻璃娃娃案之當事人間的法律關係，例如契約、無因管理和侵權行為等。最後，藉由Robert Alexy的法律論證理論，檢驗玻璃娃娃案的民事第一、二、三審判決和民法學者對此案的案例分析之中的法律論證。 / This thesis investigate the relationships between legal language, legal argumentation and daily language in the fatal accident case of osteogenesis imperfecta in Taiwan. First, we analyze legal language, legal argumentation and daily language used in the verdicts of four civil cases. We focus on the contents of verdicts. Second, from the newspaper reports of this case, we investigate the relationships between legal language and daily language. Third, the case studies by civil law researchers are investigated by the verdicts of trial of first and second instances. From the investigation of cases studies, we can obtain the connection between legal language, legal argumentation and daily language. Using the foundations of claims of civil law, we re-study the legal relationships like contracts, torts and voluntary service among clients in the case of osteogenesis imperfecta. Finally, we re-investigate the legal argumentations of the every verdicts of civil court and the case studies with Theory of Legal Argumentation proposed by Robert Alexy.
