論契約限制責任約款

Abstract

契約限制責任約款為現代交易實務中常見之風險分配工具，當事人得透過契約事先限制或免除依法原應負擔之損害賠償責任，以控制交易風險、降低交易成本並提高法律關係之可預測性，具有交易上之實用性。然而，此類約款一方面涉及私法自治與契約自由之實現，另一方面亦可能減損對債權人之保護，故其容許性及法律效果向來具有高度爭議。尤其當同一事實同時構成債務不履行與侵權行為時，債權人是否得藉由主張侵權責任而規避契約限制責任約款，更成為契約法與侵權法交會領域之重要問題。 本文首先界定契約限制責任約款之概念與範圍，並整理其常見類型及制度功能。本文認為，契約限制責任約款並非單純偏袒債務人，而係透過事前風險配置促進交易之進行。關於其容許性，本文認為契約自由雖為私法自治之核心內容，惟仍須受到強行規定、公序良俗之限制。於消費性定型化契約中，基於資訊與議價能力之不對稱，責任限制約款應接受較嚴格之效力審查；至於商業性定型化契約，則應原則上尊重當事人自主形成之風險分配安排，並採取較低密度之司法介入。 就契約責任與侵權責任之競合問題，本文整理學說與實務發展後認為，我國法上較可採取請求權相互影響說。亦即，在承認契約責任與侵權責任得競合存在之同時，應使契約中有效成立之責任限制安排，於一定範圍內對侵權責任發生影響，以維護當事人事前所進行之風險分配。至於契約限制責任約款是否及於侵權責任，本文主張應回歸契約解釋加以判斷：若約款係以特定風險事實或損害結果為規範對象，原則上應解釋為及於因該風險所生之一切損害賠償責任，而不限於特定請求權基礎。如此始能兼顧契約自由與被害人保護，並維持契約限制責任約款作為風險分配工具之制度功能。

Limitation of liability clauses are commonly used risk-allocation mechanisms in modern transactions. By limiting or excluding liability for damages that would otherwise arise under the law, such clauses enable parties to control risks, reduce transaction costs, and enhance legal certainty. However, while they reflect the principles of private autonomy and freedom of contract, they may also weaken the protection afforded to creditors and injured parties. In such cases, an important question arises as to whether a claimant may avoid a contractual limitation of liability clause by bringing a tort claim. This thesis examines the concept, functions, and validity of limitation of liability clauses. It argues that these clauses serve not merely to protect debtors but to facilitate transactions through ex ante risk allocation. Although freedom of contract should generally be respected, limitation of liability clauses remain subject to mandatory rules and public policy considerations. In consumer standard-form contracts, stricter judicial scrutiny is justified due to disparities in information and bargaining power. In commercial standard-form contracts, however, courts should generally respect the parties’ allocation of risks and exercise a lower degree of intervention. Regarding the concurrence of contractual and tortious liability, this thesis argues that Taiwanese law should adopt the theory of mutual influence between claims. While contractual and tortious claims may coexist, valid contractual limitations of liability should, to an appropriate extent, affect tort liability in order to preserve the parties’ agreed allocation of risks. Whether a limitation of liability clause extends to tort claims should ultimately be determined through contractual interpretation. Where a clause is directed at a particular risk or type of loss, it should generally be interpreted as covering all liabilities arising from that risk, regardless of the legal basis of the claim. Such an approach strikes a balance between freedom of contract and the protection of injured parties while preserving the risk-allocation function of limitation of liability clauses.
