French Administrative Contracts: Criteria, Imprévision, and Public Procurement

French administrative contract law (droit des contrats administratifs) governs agreements between public authorities and private parties, as well as agreements between public authorities themselves. Administrative contracts are subject to special rules that differ from private contract law and reflect the public interest objectives that the contracts serve. The law has been developed primarily by the Conseil d’État and is now codified in the Code de la commande publique.

Criteria for Administrative Contracts

A contract is classified as administrative (contrat administratif) based on two alternative criteria. The first is the existence of a statutory provision expressly classifying the contract as administrative. The second, developed by the Conseil d’État in the Arrêt Société des Grands Garages Parisiens (1921) and the Arrêt UAP (1999), requires that: (1) at least one party is a public person (personne publique), and (2) the contract either concerns the execution of a public service (exécution d’un service public) or contains clauses that are unusual in private law (clauses exorbitantes du droit commun).

A clause exorbitante is a contractual provision that would not be found in a private contract, such as the power of the public authority to unilaterally modify or terminate the contract, to impose penalties, or to require the contractor to continue performance despite changed circumstances. The presence of such a clause automatically classifies the contract as administrative.

Théorie de l’Imprévision

The théorie de l’imprévision (theory of unforeseeability) is a distinctive feature of French administrative contract law. Established by the Arrêt Compagnie Générale d’Éclairage de Bordeaux (Conseil d’État, 1916) and developed by the Arrêt Société Les Films Lutétia (1959), the doctrine applies when unforeseeable circumstances fundamentally disrupt the economic equilibrium of an administrative contract.

When imprévision is established, the contractor is entitled to compensation from the public authority for the additional costs caused by the unforeseen circumstances. The contractor must continue to perform the contract; the doctrine provides for compensation rather than termination. The compensation is calculated to restore the economic equilibrium that existed when the contract was signed. The théorie de l’imprévision reflects the principle that administrative contracts serve the public interest and must remain viable to ensure the continuity of public services.

Fait du Prince

The fait du prince doctrine applies when the public authority itself takes action that disrupts the contractual equilibrium. If the contracting authority, acting in its sovereign capacity, interferes with the performance of the contract, the contractor is entitled to full compensation. The fait du prince differs from imprévision because the disruptive action is taken by the contracting authority rather than by external circumstances.

The fait du prince includes measures such as the imposition of new taxes on the contractor, regulatory changes that increase the contractor’s costs, or restrictions on the contractor’s operations. The contractor must prove that the measure was taken by the contracting authority and that it directly affected the performance of the contract. Compensation under the fait du prince is more generous than under imprévision: the contractor receives full compensation for all additional costs.

Mutuum Dissensu

The principle of mutuum dissensu allows the parties to an administrative contract to terminate the contract by mutual agreement. Unlike the unilateral termination powers of the public authority, mutuum dissensu requires the consent of both parties. The agreement to terminate must be voluntary and informed, and it must respect the rights of third parties.

Mutuum dissensu is common in practice, as it allows the parties to avoid costly litigation when the contract is no longer viable or when the objectives of the contract have changed. The parties negotiate the terms of termination, including compensation for the contractor and the transfer of assets.

Concession Contracts

Concession contracts (contrats de concession) are a specific category of administrative contracts under which a public authority entrusts the execution of a public service to a private operator, who is compensated by the users of the service. Concessions are common in transportation, water supply, energy, and other public services.

The concessionaire bears the economic risk of the operation. The duration of the concession must be proportionate to the investment required and must not exceed the period necessary for the concessionaire to recover its investment and earn a reasonable return. The théorie de l’imprévision has particular importance for long-term concessions, which are especially vulnerable to unforeseen changes in economic circumstances.

Public Procurement

Public procurement (marchés publics) is governed by the Code de la commande publique, which codifies the rules for awarding and executing public contracts. The Code implements EU directives on public procurement and establishes principles of transparency, equal treatment, and competition.

Public procurement contracts may be classified as administrative or private, depending on their subject matter and the identity of the parties. The applicable legal regime varies accordingly: administrative procurement contracts are subject to the general principles of administrative contract law, while private procurement contracts are governed by the Code civil.

Remedies

Administrative contracts are subject to the jurisdiction of the administrative courts. The recours de plein contentieux (full jurisdiction action) allows the contractor to seek compensation for breach of contract, including damages for additional costs caused by imprévision or fait du prince. The recours en contestation de validité allows third parties to challenge the validity of the contract.

The public authority has special powers in the execution of administrative contracts. It may unilaterally modify the contract to adapt to changing circumstances, provided that the modification respects the contractual equilibrium. It may also impose penalties on the contractor for failure to perform, and it may terminate the contract for reasons of public interest, subject to compensation.
