隨著不動產交易日益頻繁，立體相鄰關係紛爭、都市老化乃至都市更新等問題不斷地在社會上發生，在在涉及人民財產權之保障與限制。為確保當代法治國家下之人民得以擁有基本人性尊嚴，乃至自由行使各種基本權利，須藉由系列之管制法規範（如都市更新條例、公寓大廈管理條例等）予以規制及調和。本文嘗試以法學方法為證立之基礎，藉由整合方法之思維證立管制法規範於財產權保障與限制之法教義學構造，彰顯法之正義機能，並擇定都市更新撤銷案──最高行政法院109年度判字第364號判決、強制出讓區分所有權案──最高法院108年度台上字第1541號民事判決為法教義學證立之素材：前者以都市更新條例第22條、第32條等規定於都市更新事業計畫之核定，檢視都市更新事業計畫之核定之適法性，及對於劃定更新單元內土地及建築物所有權人之都市更新正當程序，探究公共利益、正當行政程序於都市更新致使財產權變動所扮演之規制角色；後者以公寓大廈管理條例第22條第1項第3款、第2項強制出讓區分所有權之規定，進行財產權限制與居住環境權──適足居住權保障之檢討，衡酌全體大廈住戶與單一區分所有權人之利益，特別著眼於「共同關係」、「情節重大」如何闡釋及其具體類型化。

As real estate transactions become increasingly frequent, disputes arising from complex adjacent relationships and issues such as urban aging and urban renewal continue to occur in society, all of which involve the protection and limitations of individuals' property rights. In order to ensure that the people in a contemporary rule-of-law state can possess basic human dignity and exercise various fundamental rights freely, a series of regulatory laws and regulations (such as Urban Renewal Act, Condominium Administration Act Building Administration Division, etc.) must be established and harmonized. This article attempts to establish a legal foundation through legal methods, using integrated thinking to establish regulatory laws and regulations within the legal dogmatics framework of property rights protection and limitations. This highlights the justice function of the law. The article selects two legal cases for legal dogmatics establishment: the first case involves the revocation of urban renewal-the Supreme Administrative Court Judgment (109) Pan Tzu No. 364, and the second case pertains to the forced eviction unit ownership-the Supreme Court Civil Judgment (108) Tai-Shang-Tzu No.1541. In the former case, the examination focuses on the legality of the approving of urban renewal projects in accordance with the provisions of Article 22 and Article 32 of the Urban Renewal Act, as well as the proper procedures for determining ownership of land and buildings within the updated units. It explores the role of public interest and proper administrative procedures in regulating property rights changes resulting from urban renewal. In the latter case, it discusses property rights limitations and the protection of the right to a suitable living environment, in accordance with the provisions of Article 22 of Condominium Administration Act Building Administration Division, considering the interests of all building residents and individual unit owners. Special emphasis is placed on how "common relationship" and "significant circumstances" are interpreted and typified.
