Canal de Craponne, Court of Cassation (1876)
Canal de Craponne is the classic French contract-law case for the idea that judges may not rewrite a contract simply because economic circumstances have changed. It became the canonical rejection of judicial adaptation of contracts for hardship in ordinary private law.
The dispute concerned an old contract for maintenance of irrigation works, where the agreed price had become outdated because of changed economic conditions. One party asked the court to revise the contractual price.
Information not available.
The Court looked at the text of the contract and the altered economic conditions, including the long lapse of time since the agreement was made.
The claimant argued that fairness required adjustment because the original terms had become unrealistic. The opposing party argued that the court must enforce the contract as written.
The Cour de cassation refused to modify the contract.
The Court reasoned that judges are bound to apply the contract chosen by the parties and cannot rewrite it on grounds of equity or changed circumstances unless the law itself provides a basis to do so.
Canal de Craponne became the foundational French authority against judicial revision of contracts for hardship.

Can courts rewrite contracts when circumstances change?
France and the United Kingdom both have strong contract law traditions, but they approach judicial intervention in contracts very differently. Canal de Craponne (1876) established that French courts cannot rewrite contracts simply because circumstances have changed, while the UK has developed its own approach.
UK has a strong contract law tradition with different approach to judicial intervention. Why preferable to others: U.S., India, and China have different contract law traditions.
Each system arrived at the same problem from a different direction: how to balance contractual certainty with fairness when circumstances change. In France, the Cour de cassation had to decide whether courts could modify contracts for hardship. In the UK, the courts have developed doctrines like frustration and .

| Constitutional Basis | Civil Code; pacta sunt servanda | Common law; doctrine of frustration |
| Leading Case | Canal de Craponne (1876) | Davis Contractors v. Markham (1956) |
| Court's Reasoning | Judges cannot rewrite contracts for equity | Contracts can be discharged if frustrated |
| Outcome | Established judicial non-intervention | Established frustration doctrine |
Both systems recognize that contracts are binding and that parties should generally be held to their agreements. Both courts have issued landmark rulings to define the boundaries of contractual enforcement.
The divergence begins here. In France, Canal de Craponne established that judges cannot rewrite contracts simply because circumstances have changed or because the deal has become unfair. The French approach emphasizes pacta sunt servanda (agreements must be kept). In the UK, by contrast, the courts have developed the doctrine of frustration, allowing contracts to be discharged when circumstances make performance impossible or radically different. The UK approach is more flexible, allowing for judicial intervention in extreme cases. The result is a more rigid approach in France and a more flexible one in the UK.
What follows from all this is that contract law is not just about enforcement—it is about balancing certainty and fairness. In France, the rigid approach provides certainty. In the UK, the flexible approach allows for fairness in extreme cases. For citizens, both systems provide contractual stability, but the UK model allows for more judicial intervention.
Canal de Craponne and the UK's contract cases both gave judges the power to define contractual enforcement, but they approached the problem differently. One emphasizes certainty; the other flexibility. Together, they show that contracts are not just about promises—they are about relationships.
