Does the French blocking statute (Law No. 68-678) actually prevent me from responding to a US discovery request, and what penalties apply if I comply anyway?

France’s “blocking statute” (Law No. 68-678, as amended) restricts the disclosure of certain economic, commercial, industrial, financial, or technical information when that disclosure is intended for use as evidence in foreign judicial or administrative proceedings. It does not erase your obligations under a US lawsuit, and US courts have historically ordered production despite it. So the honest answer is: it complicates compliance and creates real legal exposure in France, but it does not automatically excuse you from a properly issued US discovery demand.

Two legal systems pulling in opposite directions

A US litigant operating in France can face conflicting commands. US civil discovery under the Federal Rules of Civil Procedure is broad and party-driven, and courts can compel relevant materials within their jurisdiction. Meanwhile, French law channels foreign evidence-gathering through formal mechanisms (such as the Hague Evidence Convention) and penalizes data transfers that bypass them.

US judges weigh these conflicts case by case, considering the importance of the information, the specificity of the request, whether the data originated abroad, the interests of each nation, and the good faith of the responding party. Outcomes differ by court and jurisdiction, and they are not predictable from the statute alone.

Penalties for non-compliant disclosure

Under the French statute, transmitting protected information outside the sanctioned channels can expose individuals to criminal penalties, including fines and potential imprisonment, with higher exposure for companies. France has also strengthened enforcement and oversight in recent years. Separately, the EU General Data Protection Regulation may apply to any personal data in the same documents, adding its own restrictions and fines.

A practical path

• Do not unilaterally export data or ignore either obligation; act through counsel in both countries.
• Where appropriate, pursue formal channels (for example, the Hague Convention) and seek French authority guidance before transferring anything.
• Negotiate proportional, narrowed requests and surface the conflict to the US court early and in good faith.
• Map where responsive data physically resides and what privacy regimes attach to it before collection.

Treat this as a cross-border evidence and data-protection problem, not a simple production task. For broader context, see our e-discovery topic hub. This is general education, not legal advice; engage qualified counsel in each jurisdiction.
