The FBS was enacted in 1968.[2] It was originally intended to protect French national concerns by prohibiting French persons or legal entities from communicating to foreign public authorities documents or information "the disclosure of which may damage sovereignty, security or essential economic interests of France"[3] (emphasis added). This was subject to international treaties and agreements (foremost amongst them, from 1970, the Hague Convention[4]. The prohibition was backed up by criminal sanctions, including imprisonment up to six months and fines.
The FBS' scope was significantly expanded in 1980 with the introduction of Article 1 bis – in part, a reaction against the perceived excesses of pre-action discovery in US litigation [5] – which provided that:
"Without prejudice to international treaties or agreements and laws and regulations in force, it is prohibited for any person to request, search for or communicate, in writing, orally or in any other form, documents or information of an economic, commercial industrial, financial or technical nature for the purposes of establishing evidence in view of foreign judicial or administrative proceedings or in relation thereto" (emphasis added).
In spite of the broad scope of Article 1 bis, the FBS has traditionally been seen as something of a dead letter; to date, there has been just a single reported conviction (a rather unusual case known as Christopher X, which involved a French lawyer fraudulently obtaining information from a French defendant company).
The English courts' approach to the laws of other states which seek to prohibit parties from giving disclosure in foreign proceedings, such as the FBS, has been informed by two connected principles. First, that procedural matters (such as disclosure) shall by governed by English law as the lexi fori, such that a conflicting rule of foreign law shall not be applied. And second that, in exercising that jurisdiction, the court must balance the risk to a party of prosecution for breach of the relevant foreign law against the importance of the disclosure of the documents to the fair disposal of the English proceedings. [6] In the case of the FBS, given the scant evidence of successful prosecutions, the courts were historically not persuaded to order disclosure via the cumbersome Hague Convention route.[7]
But recent developments appeared to be likely to have changed the analysis. In 2016, the Service de l'Information Stratégique et de la Sécurité Economiques (the "SISSE") was created, whose functions include overseeing the application of the FBS. This was followed by a 2019 report by Raphaël Gauvain MP recommending certain measures relating to the FBS, including the creation of a mandatory early warning mechanism. [8] In 2022, a decree was passed providing for compulsory reporting of possible disclosure requests falling under Article 1 and Article 1 bis to the SISSE, and establishing a procedure whereby the SISSE is obliged to issue an opinion on the applicability of the FBS' provisions (within one month of first report).[9] That opinion could then be used as evidence before foreign courts, where there are disputes relating to disclosure.
Taken together, these steps appeared to signal a new – more proactive – approach to enforcement of the FBS, which one might have thought would lead to a different approach from the English courts.
