暴利行為於法院裁判基準之實證研究

Abstract

本文以我國民法第 74 條規定之暴利行為為研究核心，旨在探討我國法院於 民國 103 年至 113 年間審理撤銷暴利契約案件時，對於判斷要件之邏輯架構及 價值取向。學理上，關於暴利行為與顯失公平行為之界限及構成要件判斷標 準，長期缺乏穩定之學說共識與實證檢驗;而實務上，法院對暴利行為之認定 則採取相對嚴格標準，實際獲准撤銷的案件比例偏低，顯示法院為避免過度干 預契約自由，傾向採取較嚴格之審查態度。 本文蒐集相關判決資料，透過量化分析各項變數，並結合統計方法與決策 樹模型，歸納出影響法院判斷的關鍵因素。針對「急迫」要件判斷，法院相較 經濟層面之困窘，更強調原告是否處於受他人制約或突如其來之心理壓力之境 地。「輕率」要件則著重於原告是否具備了解契約內容之管道、風險評估能力 及是否在短時間(通常為一日內)內作出決斷。「無經驗」要件則以原告之教 育程度及過往經驗為判斷基礎，評估其是否具備足以理解契約條款之能力。至 於客觀要件「顯失公平」標準，則依雙方當事人之地位與資源分配、原告之財 力和需求性、及契約之合法性及正當性加以斷定，僅在契約條款嚴重背離公平 原則時，法院方介入進行實質修正。此反映法院在尊重契約自由之原則下，採 取中立審慎之立場，並非單以契約金額高於市價或偏離常態為由，即認定其具 備顯失公平之程度。關於民法第 74 條在無償契約之適用，學說多持否定立場， 但實務仍多依原告之認知能力、風險判斷與資力綜合判斷「顯失公平」，並未 因無償即排除適用;涉及刑事告訴權之和解契約亦同。詐騙案件中，被害人之 錯誤動機並非法院判斷「輕率」之主要因素。另部分高等法院採「準暴利行為」 論證，以公序良俗保護高齡者財產及生存權，並據民法第 72 條認定給付顯失均 衡之契約無效，呈現實務對弱勢情境之補充性發展。 根據研究結果，法院判斷上重視當事人是否具備基礎生活知識，若無特殊 排除情況，進一步考量其是否具有預見契約可能帶來不利結果之能力及相關經 驗。若原告缺乏基礎之生活知識、風險辨識能力及相應經驗，法院傾向將其視 為相對弱勢，進而傾向准予撤銷判決。此外，本研究發現民法第 74 條於實務上 隱含三層適用層次，分別為「可預期」、「可理解」與「可履行」三個面向。 此三層面不僅體現立法者保護弱勢當事人之立法目的，同時亦可作為訴訟策略 制定之重要參考。整體而言，法院對暴利行為之審查態度仍屬審慎，僅於契約 條款明顯違背公平原則且有調整必要時，方會介入撤銷。本文藉由實證分析呈 現暴利行為制度於實務運作之現狀，並就司法適用及訴訟策略提出相關建議， 以期對未來學理探討與實務發展有所助益。

This article examines exploitative transactions under Article 74 of the Taiwan Civil Code, focusing on the analytical framework and value considerations adopted by courts in adjudicating actions for rescission of exploitative contracts between 2014 and 2024. In academic discourse, the boundary and doctrinal standards distinguishing exploitative transactions from unconscionable transactions have long lacked stable consensus and empirical validation. In judicial practice, courts apply a relatively stringent standard when determining the existence of exploitative conduct, resulting in a low rate of successful rescission. This trend reflects the judicial concern of avoiding undue interference with the principle of freedom of contract and thus adopting a more cautious review. Drawing from collected judicial decisions, this study conducts quantitative analyses of multiple variables and employs statistical methods together with decision- tree modeling to identify the key determinants influencing judicial reasoning. With respect to the element of “distress,” courts place greater emphasis on whether the claimant was under external pressure or sudden psychological strain, rather than merely on economic hardship. The assessment of “recklessness” centers on whether the claimant had access to channels for understanding the contractual terms, the ability to evaluate risks, and whether a decision was made within a short timeframe—often within a single day. For the element of “inexperience,” courts examine the claimant’s educational background and prior life experiences to determine whether the claimant possessed sufficient capacity to comprehend the contract. As for the objective requirement of “gross unfairness,” courts evaluate the relative positions and resources of the parties, the claimant’s financial capacity and need for the transaction, and the legality and legitimacy of the contractual arrangements. Judicial intervention is triggered only when contractual terms deviate substantially from principles of fairness. This indicates that courts maintain a neutral and circumspect stance, and do not deem a contract grossly unfair solely because its price exceeds market value or diverges from standard practice. Regarding the applicability of Article 74 to gratuitous contracts, academic commentary tends to oppose such application. Nonetheless, courts commonly evaluate “gross unfairness” based on the claimant’s cognitive ability, risk assessment capacity, and financial resources, without excluding gratuitous transactions from review; the same approach is observed in settlement agreements involving the waiver of criminal complaints. In fraud-related cases, the victim’s mistaken motivation is not treated as the core determinant of “recklessness.” Additionally, certain High Court decisions invoke the concept of “quasi-exploitative acts,” applying public-policy considerations to protect the property and livelihood interests of elderly individuals, and finding contracts with markedly imbalanced performance obligations invalid under Article 72 of the Civil Code—demonstrating a supplemental doctrinal development in cases involving vulnerable parties. The findings of this study indicate that courts place significant weight on whether parties possess basic life knowledge and, absent special circumstances, further assess their ability to foresee potential adverse consequences and their relevant experience. When a claimant lacks fundamental life knowledge, risk-recognition ability, and corresponding experience, courts tend to classify the claimant as a relatively disadvantaged party and are correspondingly more inclined to grant rescission. This research also identifies three implicit layers of judicial evaluation under Article 74: foreseeability, comprehensibility, and performability. These dimensions reflect the legislature’s intention to protect weaker parties and offer valuable guidance for litigation strategy. Overall, courts approach exploitative transactions with caution, intervening only where contractual terms clearly violate fairness principles and correction is necessary. Through empirical analysis, this article illustrates the contemporary operation of the exploitative transaction doctrine in judicial practice and proposes recommendations regarding judicial application and litigation strategy, with the aim of contributing to future doctrinal development and practical implementation.
