GAB is pleased to welcome back Frederick Davis, a lawyer in the Paris office of Debevoise & Plimpton, who contributes the following guest post:

The Supreme Court of France recently reversed two criminal judgments on the application of the international double jeopardy principle (or ne bis in idem, as the principle is known in Europe and elsewhere) in transnational bribery cases (and others). Taken together with some other recent developments, these developments suggest a renewed determination in France to regain leadership from US prosecutors in enforcing international bribery norms in France.

The ne bis in idem principle limits prosecutors’ power to pursue individuals or companies already convicted or acquitted elsewhere, including in other countries. Several European countries have domestic laws endorsing this principle; in France, the prosecutor is not bound by non-French outcomes if the French prosecution is “territorial” (that is, if an element of the offense took place on French soil) but cannot prosecute a defendant already pursued elsewhere if the only French basis for prosecution would be so-called “extraterritorial” principles (such as French citizenship of the perpetrator or the victim). Separately, a number of Europe-wide treaties, the most effective of which is the Convention Implementing the Schengen Agreement (CISA), have provisions that, with some exceptions, basically mean that no one can be prosecuted twice in Europe for the same offense.

But these provisions do not apply to US prosecutors, who are by far the most aggressive and effective pursuers of cross-border crimes such as overseas bribery. US courts interpret the Double Jeopardy clause of the Fifth Amendment to mean only that a single sovereign cannot prosecute the same defendant twice for the same offense. Some have argued that the US position creates a tension with Article 4.3 of the OECD Anti-Bribery Convention, which provides that when more than one country is competent to prosecute, they must consult to “determin[e] the most appropriate jurisdiction for prosecution,” clearly contemplating that only one country prosecute a given defendant for the same acts. But for reasons I have explored elsewhere, as well as in this space here and here, US prosecutors have not followed the spirit of Article 4.3, instead acting as the “final arbiter” of outcomes around the world, not hesitating to bring actions if they deem non-US outcomes insufficient.

Two formally unrelated decisions of the Paris Court of Appeals in 2016 – the ones that the French Supreme Court just vacated – seemed to complicate matter still further: Continue reading →
