Introduction
The principle of pacta sunt servanda, meaning “agreements must be kept,” is a cornerstone of contract law worldwide. It ensures commercial certainty by obliging parties to honor their contractual commitments. However, its application varies across jurisdictions, influenced by public policy, fairness, and statutory protections. This practice note examines how different legal systems interpret and enforce this principle, supported by landmark case law.
Comparative Application Across Jurisdictions
| Jurisdiction | General Approach | Key Case Law | Outcome & Principle |
| South Africa | Strong adherence to pacta sunt servanda, but tempered by public policy, fairness, and constitutional values. Courts emphasize sanctity of contract but occasionally balance it with equity. | Mohamed’s Leisure Holdings (Pty) Ltd v Southern Sun Hotel Interests (Pty) Ltd (2017, SCA) | Court upheld a cancellation clause, rejecting the infusion of ubuntu or generalized good faith. This reaffirmed that pacta sunt servanda remains central unless a term is unlawful or contrary to public policy. |
| South Africa (recent) | Recent authority continues to favor enforcement of clear commercial bargains, with public policy and constitutional values acting as controls only in limited cases. | 68 Wolmarans Street Johannesburg (Pty) Ltd v TUFH Ltd (2024, SCA); Municipal Employees Pension Fund v Aspara Tech and Projects (Pty) Ltd t/a Gadget Solutions (2024, Gauteng Local Division) | The courts enforced clear default and renewal provisions, rejecting attempts to invoke fairness, ubuntu, or public policy to avoid agreed wording where the clauses themselves were lawful and certain. |
| United Kingdom | Pacta sunt servanda underpins freedom of contract. English courts continue to prioritize contractual certainty and are reluctant to require parties to accept non-contractual substitutes for the bargain they made. | Printing and Numerical Registering Co v Sampson (1875); Cavendish Square Holding BV v Makdessi [2015]; RTI Ltd v MUR Shipping BV [2024] UKSC 18 | The modern position remains strongly enforcement-oriented: freely agreed bargains are upheld, subject to established limits such as the penalty doctrine and the wording of force majeure clauses. In RTI, the Supreme Court reinforced that clear contractual rights are not displaced absent clear drafting. |
| United States | Strong enforcement of contracts, but doctrines such as unconscionability, public policy, and statutory consumer protections qualify the principle. | Williams v Walker-Thomas Furniture Co (1965, D.C. Circuit) | The court refused to enforce an oppressive contract under the unconscionability doctrine, showing that fairness concerns can limit strict enforcement. |
| Germany | German law treats contracts as binding, while controlling their operation through good faith and changed-circumstances doctrines. | Bürgerliches Gesetzbuch §§ 242, 313 and 138 | The modern German position emphasizes predictability and enforcement, but performance and remedies remain shaped by Treu und Glauben (§ 242 BGB), the doctrine of disruption of the basis of the transaction (§ 313 BGB), and invalidity for immorality or serious public-policy concerns (§ 138 BGB). |
| France | Pacta sunt servanda is codified in Code civil Article 1103, but enforceability remains bounded by protection of essential obligations and mandatory rules. | Chronopost v La Poste (1996, Cour de cassation); Code civil Articles 1170 and 1171; Cour de cassation, Commercial Chamber, 3 July 2024, No. 21-14.947 | French law continues to uphold negotiated allocations of risk, while invalidating clauses that deprive an essential obligation of its substance. The 2024 case law also strengthens contractual certainty by allowing certain agreed liability limits to be relied on against third parties invoking a contractual breach in tort. |
Key Insights
- Universal principle: All jurisdictions discussed continue to recognize pacta sunt servanda as foundational to commercial certainty.
- Modern trend: Recent decisions in South Africa and the United Kingdom underscore judicial reluctance to re-make commercial bargains or dilute clear contractual language through broad appeals to fairness.
- Limits vary:
- South Africa & UK → strong enforcement, with public policy operating as a real but narrow control.
- US → unconscionability and consumer-protection doctrines remain more prominent limits.
- Germany & France → civil law systems maintain binding force while mediating outcomes through good faith, changed circumstances, and mandatory rules protecting essential obligations.
- Practical implication: For commercial drafting, recent developments favor precision in default clauses, renewal mechanisms, force majeure wording, and risk-allocation provisions such as exclusions and limitations of liability.
Conclusion
Pacta sunt servanda remains a fundamental principle underpinning contract law globally, ensuring that agreements are honored to maintain commercial stability. Nonetheless, its application is not absolute; courts across jurisdictions recognize the need to balance enforcement with fairness, public policy, and statutory protections, reflecting evolving societal values and legal norms.
