Introduction
In contract law, unforeseen events can fundamentally alter the basis upon which parties agreed to be bound. Legal systems provide mechanisms to address such situations, balancing the principle of contractual certainty (pacta sunt servanda) with the need for fairness when circumstances change dramatically. French law employs two key doctrines in this area: force majeure and, more recently, imprévision (hardship). While force majeure has long been a feature of the French legal landscape, dealing with situations where performance becomes impossible, the doctrine of imprévision was only formally codified for private law contracts in the significant 2016 reform of the French Civil Code (Code civil). This essay will explain the concepts of force majeure and hardship in French law. It will outline the legal requirements and consequences of force majeure under Article 1218 of the Code civil. It will then trace the evolution of the hardship doctrine from its historical rejection in the famous Canal de Craponne case to its modern codification in Article 1195, before briefly distinguishing the two concepts.
Force Majeure: The Traditional Doctrine of Impossibility
The doctrine of force majeure provides a defence for a party who is unable to perform their contractual obligations due to an external, unforeseeable, and irresistible event. It addresses situations of impossibility of performance. The concept is now codified in Article 1218 of the Code civil, which was introduced as part of the 2016 reform but largely restates principles from previous case law (Fauvarque-Cosson and Mazeaud, 2018).
Article 1218 defines force majeure in contractual matters as an event that is beyond the debtor's control, could not have been reasonably foreseen at the time the contract was concluded, and the effects of which cannot be avoided by appropriate measures. This definition synthesises the three traditional conditions established by the French courts: externality (extériorité), unforeseeability (imprévisibilité), and irresistibility (irrésistibilité) (Zimmermann, 2017).
The first condition, that the event must be beyond the debtor's control, encompasses the traditional idea of externality. The event must not be attributable to the debtor's own actions or an issue internal to their business, such as a strike by their own employees unless it is a national general strike (Cartwright, 2016).
The second condition is unforeseeability. The event must not have been something the parties could have reasonably anticipated when they made their agreement. For example, a hurricane in a region where hurricanes are common may not be considered unforeseeable, whereas an unprecedented natural disaster might be. The assessment is made at the moment the contract is concluded.
The third and most important condition is irresistibility, which means the debtor is unable to perform their obligations. This implies not only that the debtor cannot prevent the event from occurring, but also that they cannot overcome its consequences. Performance must have become impossible, not merely more difficult or expensive (Jansen and Rademacher, 2018).
The consequences of a successful force majeure claim depend on whether the impossibility is temporary or permanent. According to Article 1218, if the impediment is temporary, performance of the obligation is suspended unless the resulting delay justifies termination of the contract. If the impediment is permanent, the contract is terminated by right (de plein droit), and the parties are discharged from their obligations. This provides a clear, if drastic, solution to situations of genuine impossibility.
The Doctrine of Hardship (Imprévision): From Judicial Rejection to Codification
In contrast to force majeure, the doctrine of hardship, or théorie de l'imprévision, does not concern impossibility of performance but rather situations where performance, though still possible, has become excessively onerous for one party due to a change in circumstances. For over a century, French private law, as enforced by the Cour de Cassation (the highest civil court), steadfastly refused to admit a general principle of hardship that would allow a judge to revise a contract.
The landmark case embodying this position is Canal de Craponne (Cass. civ., 6 March 1876). In this case, a contract from the 16th century set a fee for supplying water. Due to inflation over 300 years, the fee had become completely inadequate to cover the costs of maintenance. Despite the obvious imbalance, the Cour de Cassation refused to allow the fee to be revised, holding that no consideration of time or equity could permit a judge to modify the agreement of the parties. The court upheld the absolute binding force of the contract, stating that Article 1134 of the old Code civil (now Article 1103) required parties to be held to their original bargain, however harsh the outcome.
This rigid position was often criticised for its potential to create severe injustice and was out of step with French administrative law, which had long allowed for the revision of public contracts under a similar doctrine (Deshayes, Genicon and Laithier, 2017). It also contrasted with the law in many other European countries and with international soft law instruments like the UNIDROIT Principles of International Commercial Contracts, which contain provisions on hardship. Over the years, French courts sometimes used other legal tools, such as the duty of good faith (bonne foi), to encourage renegotiation, but there was no general right to have a contract revised by a court on the grounds of hardship (Fauvarque-Cosson and Mazeaud, 2018).
The 2016 Reform and the Introduction of Article 1195
The 2016 contract law reform marked a revolutionary change by finally introducing a general doctrine of hardship into the Code civil. The new Article 1195 establishes a legal framework for dealing with imprévision. It allows for judicial intervention in a contract if three conditions are met.
First, there must be a change of circumstances that was unforeseeable at the time of the contract's conclusion. This requirement is similar to the unforeseeability condition in force majeure. Second, the change must render performance of the contract "excessively onerous" (excessivement onéreuse) for a party. This is the core of the hardship doctrine and distinguishes it from force majeure, as performance remains possible. Third, the party claiming hardship must not have accepted to bear that risk in the contract. Parties remain free to include clauses that allocate the risk of changing circumstances, thereby excluding the application of Article 1195 (Deshayes, Genicon and Laithier, 2017).
Where these conditions are met, Article 1195 sets out a structured, multi-stage process. The disadvantaged party may first request renegotiation of the contract from the other party but must continue to perform its obligations during this period. If the renegotiation fails, the parties can jointly agree to terminate the contract or ask a judge to adapt it. If the parties cannot reach an agreement within a reasonable time, one party may unilaterally petition the court to revise the contract or terminate it at a date and on such terms as the court determines. This granting of power to the judge to revise the terms of the agreement is the most significant departure from the old Canal de Craponne jurisprudence (Cartwright, 2016).
The Relationship Between Force Majeure and Imprévision
Following the 2016 reform, French law now has two distinct statutory doctrines for dealing with unforeseen events. The key distinction lies in the effect of the event on performance. Force majeure (Article 1218) applies when performance becomes impossible. Its consequence is the suspension or termination of the contract. In contrast, imprévision (Article 1195) applies when performance is not impossible but has become excessively onerous. Its primary goal is to save the contract through renegotiation and, if necessary, judicial revision, with termination being a final option. The threshold for force majeure is therefore higher, leading to a more definitive remedy, whereas imprévision offers a more flexible set of solutions aimed at restoring the contractual equilibrium (Jansen and Rademacher, 2018).
Conclusion
In summary, French contract law provides a two-tiered system for addressing supervening events. The long-standing doctrine of force majeure, now codified in Article 1218, excuses non-performance when an event renders it impossible. The more recent and groundbreaking introduction of imprévision in Article 1195 provides a remedy for hardship, where unforeseen circumstances make performance excessively onerous but not impossible. The introduction of Article 1195 was a major step away from the rigid principle established in Canal de Craponne, empowering judges to revise or terminate contracts to achieve a fairer outcome. This reform has brought French private law into line with many other legal systems and modern commercial practice, creating a more flexible and arguably more equitable framework for managing contractual relationships in the face of unexpected change.
