As France is traditionally opposed to electronic voting, especially when used in general elections or national referenda, electoral interference could take the form of false information disseminated online. Indeed, misinformation may affect the honesty of electoral debates and influence voting behavior. This article first studies the electoral interference that occurred in France, during the 2017 presidential campaign, and that targeted more particularly the future president of the republic, Emmanuel Macron. It shows that the laws that existed at the time could only imperfectly counter disinformation spread in an online environment. This article then analyzes the new laws on the fight against the manipulation of information, adopted in reaction to the 2017 electoral interference with the support of the president of the republic. It studies how those laws aim to react to manipulation of digital information before general elections and national referenda. A new judge sitting for urgent matters may order the suspension or suppression of limited digital false information. The French regulatory broadcasting agency may suspend, interrupt, or refuse broadcasting of false information by audiovisual media controlled or influenced by a foreign state. Its powers are, however, restrained for legal and political reasons. This article then studies how the new laws aim to prevent manipulation of digital information. They give users of online platforms more means to critically assess digital information and be less influenced by it. Thus, online platforms must be more transparent about the information they host, especially during electoral campaigns. Furthermore, information and media literacy are strengthened. Finally, this article concludes that the scope of the new legislation against the manipulation of information, constrained by the freedom of expression, remains modest. It argues that facilitating the detection of false information by platforms' users is the way forward to diminish the impact of that information on electoral debates.
