The Return of Judicial Sovereignty in International Contracts

Both cases arose from the Lebanese financial crisis, which prevented many depositors from accessing their savings.

In each case, the agreements concluded with a Lebanese bank contained a jurisdiction clause conferring exclusive jurisdiction on the courts of Beirut.

Yet the French Court of Cassation reached two different conclusions.

In the first case, the consumer was domiciled in France when proceedings were commenced. The Court held that a clause designating a foreign court could not deprive that consumer of the right to bring proceedings before the French courts.

In the second case, however, the claimants were domiciled in Portugal. There, the jurisdiction clause remained fully effective.

The decisive factor was therefore neither the contract, nor the bank, nor even the nature of the dispute.

It was the consumer’s place of residence at the time they sought to enforce their rights.

At first glance, these rulings might appear to concern little more than a refinement of consumer protection law.

In reality, they illustrate a broader shift.

For many years, the expansion of international commerce was accompanied by an increasing contractualisation of jurisdictional rules. Parties enjoyed considerable freedom to determine in advance which court would resolve any future dispute.

The decisions handed down on 25 March 2026 remind us that this logic now has limits.

Where access to justice concerns the protection of a consumer domiciled in France, contractual autonomy gives way to a higher imperative: ensuring effective access to the French courts.

Residence therefore ceases to be merely a connecting factor for jurisdictional purposes.

It once again becomes an instrument of legal protection.

The significance of these decisions reaches well beyond the context of the Lebanese financial crisis.

Cross-border contractual relationships now involve banks, digital platforms, service providers, fintech companies, as well as suppliers and hosting providers established outside the European Union.

Against this backdrop, the drafting of jurisdiction clauses has become an increasingly important point of attention in international contracts.

The Court of Cassation’s decisions make clear that such clauses do not operate without limitation.

Where fundamental considerations of protection come into play, national courts retain the ability to reaffirm their jurisdiction.

More broadly, these decisions reflect a wider trend visible across several areas of law. The globalisation of commercial relationships no longer necessarily entails a gradual withdrawal of State authority. On the contrary, it is increasingly accompanied by the reassertion of the State’s role in protecting certain categories of litigants and preserving the effectiveness of its judicial system.

Jurisdiction clauses remain an essential feature of international commerce.

The decisions of 25 March 2026 do not call that principle into question.

They do, however, demonstrate that jurisdiction can no longer be governed exclusively by party autonomy where overriding considerations of protection are involved.

The real significance of these rulings therefore extends beyond the boundaries of private international law.

They illustrate the way in which national courts are gradually redefining their role in response to the increasing contractualisation of cross-border legal relationships.

Perhaps the question is no longer how far contractual arrangements can organise the administration of international justice.

The more fundamental question is under what circumstances States consider that protecting those subject to their jurisdiction justifies reclaiming control over that framework.
